Email Newsletter Open Rates: April 2008

Posted by Justin Premick

Think you know the best day and time to send your email newsletter?

Ever wonder if your fellow email marketers are all sending at the same time you do?

Convinced your open rate is too low (or amazingly high)?

Some recent statistics pulled from all AWeber users may help you answer these questions:

What Kind of Open Rates Are People Getting?

If you’re sending HTML emails, you probably use your open rate to help gauge your success.

Even though it’s not a perfect measure of whether people are actually opening and reading your emails, it’s useful as a relative measure:

If it goes up over a short period of time, more people are probably reading
If it falls over a short period of time, it’s almost certain fewer people are reading.

Plus, all other things being equal, it can give you some motivation (if your open rates are lower than other senders’) or satisfaction (if your rates are higher).

So, here goes…

Average Open Rate Last Month: 13.6%

When Is/Was The Best Day To Send?

You’ll often hear (at least, I often hear) that Tuesday is the optimal day to send, because on Monday people are catching up from the weekend, and that on Tuesday morning you’ll have their undivided attention before they jump into their work for the upcoming week.

Do the numbers back up that theory? Let’s see.

The breakdown of open rates by day of the week:

Monday
13.67%
Tuesday
13.21%
Wednesday
14.07%
Thursday
14.52%
Friday
13.25%
Saturday
12.09%
Sunday
13.26%

Last month, Tuesday was actually the second-worst day to send, at least if you’re measuring by open rates.

(While we’re breaking assumptions, I should point out this, too: the hour of the day that got the best open rate was not 8-9AM, or 9-10AM, but in fact 2-3PM Eastern Time — email newsletters sent during that hour last month enjoyed a 19.1% open rate.)

Does This Mean I Should Switch My Campaigns To Thursdays?

In a word: No.

Don’t break with your readers’ expectations just to try to follow the latest day of the week stats. You might actually reduce your open rate by doing so.

In both March and February, Thursday newsletters got the 3rd-worst opens vs. the rest of the week.

I hesitated a little to publish these stats, because I’m concerned that people might flock to sending their newsletters at the day or time that happened to get the best results lately.

Please, don’t drastically change your sending times/days just because you see that the average last month, or any month, happened to be higher on a different day or time.

Yes, you might eventually be able to shift your sending schedule, or split test some broadcasts, but if you up and move everything, you may throw off subscribers who are used to hearing from you at the usual time.

“It’s So Busy, Nobody Goes There Anymore”

To get at the other reason for not shifting your sending based on these stats, let’s paraphrase Yogi Berra (see above).

If everyone switches their sending schedule to send on say, Thursday, then recipients will start getting a ton of email that day, and start paying less attention to each individual email.

One possible reason for Thursday’s success last month may be that it wasn’t as popular as say, Tuesday or Wednesday for sending email:

Percentage of Newsletters Sent by Day
Monday
16.0%
Tuesday
17.7%
Wednesday
16.9%
Thursday
16.6%
Friday
15.2%
Saturday
8.8%
Sunday
8.8%

Those higher-volume days mean more emails in readers’ inboxes, which might contribute to reduced open rates. Following that reasoning, some people may look at the low weekend volume (more email newsletters were sent on Tuesdays than on Saturdays and Sundays combined) and see an opportunity to get their audiences’ undivided attention.

My main point in showing these is to point out that our assumptions about what works are often quite wrong, and that you ultimately have to test for yourself to see what best suits your audience.

Some Inspiration… And Some Help

Are you getting better open rates than this?

If so, GREAT! Give yourself a pat on the back…

…but don’t get complacent. Open rates aren’t the be-all, end-all of email metrics. They don’t guarantee that people are reading your emails, only that they have images turned on and that they probably saw your email for at least a moment.

Plus, there’s always room for improvement, right?

Some ideas that can help you raise your open rates:

Ask people to add you to their address books. Some email programs will display images from senders who are in the recipient’s contact list.
If you are putting pictures in your emails, use the ALT text for those images to pique readers’ interest in what the picture is, so that they enable images. Or, just directly ask readers to turn on images!
Add a picture of yourself to your emails, near/next to your signature. People like seeing your smiling face, and if they see it in one of your emails, they may be more likely to turn on images to see it again later.

    Great info! I am enjoying a healthy 46.8% open rate with a 34.8% CTR.

    I send out my newsletter every Wednesday at 11 a. m. and any promotions at 2:00 p. m.

    Thanks Aweber for the info!

    Justin,

    Great article.

    Since 2001 I have pretty much emailed my list once a week 3 weeks a month then a promo email followed by a few follow-up emails all in one week during the final week of the month.

    That has made me some serious cash.

    But lately I have been told daily email is the way to go. Put up a small post on your blog, email your list and tell them to read it.

    My open rate is much higher than 13.6% and always has been, but can you give us a comparison of open rates for lists mailed 5+ times a week versus 1 or 2? iEntry.com does daily email and I according to their GM (who I had lunch with last year), their readership has daily net growth.

    Curious what you can tell us Justin.

    Dear Justin, I did not know you twitt :)

    I found that not all lists open rates are equal, and only testing will teach you a thing or two about these metrics.

    I never had more than 25% open rate, and I wonder how Diana Fontanez got a whopping 46.8%..

    It’s bad that most AWEBER users have no clue how to use these stats, and barely test them.

    Is it because we tend to ignore easy or simple things?

    I’d like to see statistics on great subject lines, the best pulling results..

  4. T.M. Harris
    May 14th, 2008 at 8:58 am

    I’m amazed that she’s achieving this 46.8% open rate. It can probably be attributed to a few things…

    1) Her RELATIONSHIP with her subscribers

    2) The scarcity of her email messages. She probably doesn’t email them all the time, and leaves them hanging to her every word because they don’t hardly hear from her.

    3) I definitely believe her CTR rate, because at times I experience similar results. It’s all in the way you DIRECT your reader to the link. If you demonstrate a NEED to click the link for something that’s beneficial or inspiring, they’ll click. If there’s no reason to click, THEY WON’T. Point blank.

    Good article, Justin…and kudos to Diana.

    Aaron;

    I had exactly the same question of Justin — it is hard to judge the open rate without knowing the frequency (or the quality of the content, for that matter).

    I am curious about your statement that your open rate is "much higher than 13.6%." That is really fantastic. Can you please elaborate on why that is (or point me to a resource on increasing open rates)?

    Thanks!

  6. Justin Premick
    May 14th, 2008 at 10:35 am

    Aaron,

    How are we defining "the way to go?" In other words, what metric/s should we use as a measurement of whether more frequent email is better?

    Depending on whether we used average open rate, total opens per week, average click rate, total clicks per week, revenue, unsubscribe rate, change in list growth (to name a few possible stats), we might find that daily emails were more successful than say, weekly ones. And let’s not forget revenue (that’s why you have an email campaign, right?). Open rate is one possible measurement of success, but it isn’t the only one.

    It’s also worth remembering that drastic changes to your email practices (such as ramping up frequency from weekly to daily) can drive away your current subscribers, who are used to what you do now. Shifting expectations takes time.

    That said, if you’re interested in being a guinea pig and doing a case study on making those kinds of changes, I’ll gladly talk to you about it :)

    Codrut,

    Testing is definitely the way to go, because as you say not all lists are equal (plus opens don’t necessarily yield clicks or sales).

    For those who are not making use of stats, I’d say it’s mostly a question of not being sure what changes to make.

    For example, if your open rate is consistently 15%, what should you change to make it 18%? There’s no universally right or wrong answer. There are many things you could try in the subject line, in the body of your emails and in your overall strategy.

    Dear Justin,

    This is pretty helpful stuff!

    I was thinking exactly as everybody else! :) Now I am wiser or at least more informed :)

    I track and split-test almost everything… And sometimes get "lucky" with a weekend offer… :) (made a habit of braking habits.) But your test results and advise really makes sense to me.

    Thanks for your passion and for sharing

    Hi,
    I think that email with some expected value in it will have better open rate. And statistic will tell us what we want to hear. Open rate in percentage. ok but from which volume of emails?? Maybe that 12% is much more emails than some 14%?? I think, open rate statistic is important for accidental emails (spam, which we are not doing, are we?), and for those who bombard their poor subscribers with a ton of emails. I mean we all open our bank statements (and similar emails) with 99% open rate. Am I right? So, value of the emeil…..

    Wow! I’m feeling a LOT happier about my open rates having read the averages here.

    I agree that testing is the only way to know which day and which subjects work best for your subscribers. I’ve been surprised to see my open rate go up on or just before a holiday. I always thought that fewer people would be reading their email on those days.

    My main newsletter goes out on Tues. but a few times I’ve sent announcements on a Sunday thinking that they’d be opened on Monday. Not so, the few Sundays I sent email, the rates were as good or better than my average.

    The open rate for my e-courses averages 80%. Clearly, the folks wno sign up for follow-ups are more dedicated to getting the information than folks who sign up for newsletters.

    As with everything else involving humans, there are no sure guidelines. We must each test to see what works for our subscribers. Then test and retest.

    Not too concerned about open rates on any given day, more concerned about persistence and consistency in sending out auto responders. I find that 2 or 3 auto responders per week, keeps my name in front of my prospects.

    I often have prospects call me up several months later, and say, Ray you must be real, been getting all those emails, from you for the past seveal months, so sign me up, I’m in!!!

    It is really that simple, with A-Weber auto responders and email campaigns.

  12. Aaron Abber
    May 14th, 2008 at 12:02 pm

    @Mark,

    Open rate for my weekly newsletter (started in 2001) was over 45% *for first year subscribers*. Click thru rate was consistently over 75% of opens.

    Since most of the time my promo emails were text, I don’t have open rate data. However with a multi-send, one week promotion I tended to see visits in the 90% range of number sent. Otherwise, on multiple text emails I sent promoting a product or service the number of visits correlated to about 90% of the number of individuals sent the emails.

    @Justin,

    I was thinking of open rate, though as you imply simply looking at open rate may give a false perspective–correlation doesn’t necessarily mean causation and open rate doesn’t mean profitability. Still it would be interesting to see large scale open rate data broken down by frequency.

    I’ll send you a private email about being a guinea pig.

    @Dr. Brown,

    Have you tested Fri v. Sat v. Sun? Just curious.

  13. Justin
    May 14th, 2008 at 12:15 pm

    Interesting info Justin. I send my weekly newsletter out on a Tuesday and we average around 80% open rate (we even had 99% open rate a few weeks ago).

    We used to send it out on a Saturday and that worked quite well too. In fact, weekend emails we found were actually read more in-depth as people obviously had more time.

    Great stats though, thanks for sharing.

  14. Aidan Crawford
    May 14th, 2008 at 4:05 pm

    13% seems really low considering the double opt-in hassle for subscribers. I’d think they would be really interested in receiving what they asked for.

    When we brought our list to aweber we had 27000 folks registered and that number dropped to about 3000.

    Our open rate is between 70 and 75%.

    It was a splash of cold water to see the initial numbers - especially as the guy who persuaded the boss to move to aweber in the first place - but real numbers are better than fantasy numbers.

    I think open rate is over-rated.

    If it’s a promotional email you should also look at $earned / emails sent.

    May 14th, 2008 at 4:50 pm

    Obviously profit is the biggest measure of success for any business.

    But open rate is one of the factors involved in the process of profiting from your list. If a mail never gets opened, there is no profit. Learning how to make each step of the process more effective ensures the highest profit per subscriber.

    Justin,

    Thanks for the great info. I was just wondering last night what a typical open rate was.

    I am happy to report I am achieving a 60%+ open rate. And I was frustrated it wasnt higher -lol.

    And Aaron - thanks for referring me to aweber.

  22. Jeff F
    May 15th, 2008 at 1:33 pm

    This post really is reassuring! I was thinking along the same lines as Sean. My lowest open rate was 60.8% with a highest being 82.3. Avg would say about 77%. Click throughs have been about 10-33% for me.

    I don’t send too often, and when I do, about 95% of the content is just useful helpful information to fellow guitar players and musicians. Usually I will tie in the information at the very end to something that I am promoting with a brief call to action.

    It really does come down to your relationships with your subscribers, the type of site or product you are promoting, and having a compelling headline that really makes the reader want to learn more. Emphasizing their benefits or sparking their interest in the headline is a must.

    My lowest open rate mailer had a headline "Please help GuitarPlayerZen.com with this Survey"

    No wonder.

    Hi!

    Interesting facts.

    However, I am an Artist and not a statistician, but those open rates for Monday, Tuesday, Wednesday, etc. might not be different in a statistically significant matter anyway.

    I personally open every single newsletters from folks I "like" regardless when they have sent it. Even, if the subject line sucks.

  25. Justin Premick
    May 15th, 2008 at 2:56 pm

    Great to hear that so many of you are getting open rates above the average :)

    Elandria,

    As you have illustrated, there are definitely other factors that go into whether your subscribers will read your emails.

    Recognition of you as the sender (provided the reader has a positive association with you) will contribute to getting an open. So will your copywriting in the subject line. So will overall frequency with which you send email.

    Day and time certainly aren’t the only factors influencing open rates.

  29. Justin Premick
    May 16th, 2008 at 8:55 am

    Stephen,

    There is typically an inverse correlation between list size and open rates, yes.

    Generally speaking, the larger a list gets, the "older" its subscribers are. Newer subscribers will read your emails more frequently than older ones, because they just expressed an interest in whatever your email campaign is about.

    Larger lists also tend to be less focused. Know the saying, "you can’t please everyone?" It applies to email, too… you’re much more likely to send a message to 100 people and have it be compelling for all of them, than you are to do the same thing for a list of 100,000 people.

  30. Aaron Abber
    May 16th, 2008 at 10:01 am

    @Stephen,

    When I quoted the open rate above I specified "first year subscribers." Typically this was around 10,000 sent.

    What I found with "aged" subscribers is that the open rate seems to stabilize after the first 12 months–dropping to 10%-15% for subscribers 13-48 months. But here’s the good part: Aged subscribers who open the email almost always click-thru to the site, making "aged" subscribers much more profitable per open than new subscribers.

    Justin,

    Great article.

    And a question. If I send an html email whose content is smaller than the preview pane in lets say Outlook the recipient may not choose to so call open the email, because they’ve seen the content so to speak.

    So my question is this, if an email only shows in a preview screen and is not double-clicked on (fully opened), would that be tracked as opened or not with Aweber’s system.

    And if there is a web url hyperlink that they click on in the preview screen (again not in the fully opened email), does that change how Aweber tracks the html email open rate?

  33. Justin Premick
    May 16th, 2008 at 1:02 pm

    Robert,

    When a program like Outlook loads your message in the preview pane, as long as you have images enabled for the message, an open will be recorded.

    Open rate tracking is unaffected by whether the subscriber clicks any links in your message.

    May 17th, 2008 at 9:34 am

    These numbers were very interesting to me… I just started our list almost eight weeks ago, and am sad that it is only up to 80 subscribers so far.
    But it turns out we are getting very high opens at 74.53%. But since they are all new subscribers, the fact that the rate is so high is explained partly by the fact that they are all new subscribers, although many are long-time customers.
    Our click through rate is 34.7% which I see is also pretty high! Cool. The same reasons as above partly apply.. plus this… I have only sent six messages in those eight weeks.. and each time I have sent the mail, it was due to an important sale or variety we were offering at that time. Since we are an agricultural operation with definite swings in production due to weather, I started the mailing list so I can encourage our customers to take advantage of the flushes of growth by offering various grades and prices while the plant growth is strong. My mail subject line will state the reason for the mailing (i.e.: heavy production this week with attendant lower prices… or some info as to the next weeks production). I expect to use it also to caution customers when the plants will go into a ‘dormant’ or slowdown phase, so they know to stock up now while we have plenty available. This should keep people buying when we have high availability, yet allow the plants their needed dormancies as our customers will have stocked up.

    I look at the list as a way to acquaint our customers with the needs of the plants, so that they may take advantage of the plants growth cycle when production is high, and also warn them of upcoming slow-downs in production so that they will not be shocked and upset when I must remove some produce offline from sale, or raise the price due to low availability. In essence, my mails are designed to keep potential customers aware of the needs of the plants, so that they can more effectively keep themselves supplied with cactus.

    Perhaps another reason for high opens is the fact that I have only mailed six lists in eight weeks, and each time I have mailed it was a ’sweet and short’ message giving some special price or advice as to ordering with an eye to convincing customers now was a good time to visit the site to consider whether they wish to order now.

    While our open rate seems to be high, our click-through rate at 34.7% does not seem so far above the average as the open ratio is.. this is explained by the fact that my mails are succinct (unlike this message) and give an explanation of the purpose of that particular mail. Since our message is not pertinent to all users at that time (some will not want the particular cactus featured), subscribers who do not want that cactus will not click through.. perhaps in several weeks time, I might offer a special due to high availability and growth of the plants they do like, this is the mail they will click on and follow through, while perhaps the person who clicked though weeks before will not due to it not being his ‘cup of cactus’.

    Thanks for making this service available, I expect it will increase our customer awareness of our unique agricultural challenges, and help us keep our customers happy with our produce and practices.

    I do wish I had been engaging in a mailing list for several years, I would have many more subscribers, and the past delays in production due to weather and deer or insect damage would be easier to explain to people.

    May 18th, 2008 at 2:33 am

    Justin, thanks for the information. It is very interesting to compare.

    One question: Does the open rate statistic reflect ‘unique’ opens, or every open? I am assuming every time it gets opened, the open-count goes up. Is that right? If not, can you explain explicitly how the number is tracked?

    Hi. Just wanted to share my 2 cents on my open rate.

    It all begins with the relationship you are building with your subscribers.

    If they like, trust and know you, AND like the messages you are sending (quality, not quantity), then they will wait for your newsletter.

    I also noticed that the biggest open rates happen when I start the message with their name. But i only do this when i am going to send out a promotion or anything else besides my newsletter.

    I recently sold out a teleseminar (in spanish) and asked my clients, who purchased for the FIRST time, to tell me the reasons they bought.

    (This is great feedback that proves that building a relationship with your list is the key to good open rates, great CTR and greeeaaat $$).

    REASONS WHY READERS BOUGHT:

    1. Consistency - Train your readers to expect you. Be there exactly the same hour at the same day of the week that you choose. This builds expectation and trust with your readers.

    2. Connection - Build a connection with your readers. Be human! Share personal things about your life. I get the most CTR’s when i share something about my life. Don’t be afraid to be human. People buy from people, not from companies.

    3. Show, don’t tell - Whatever market you are reaching, the sure way to position yourself as an expert is to prove that you are one. I write a lot about SEO but prove to my readers that I am strongly positioned in Google (87% of my traffic comes through search engines).

    Well… There you have it! Just my thoughs from the beautiful island of Puerto Rico. :)

  39. Dylan

    I certainly agree that open rates are important but they SHOULD NOT be the ONLY thing you track. By the way, I’m positive that for every 3 person that tracks their open rates, another 3 probably don’t care. I’m not 100% certain though, maybe justin can throw some light on it!

    In addition to open rates, you should be checking your unsubscribe rates, your click-through rates and eventually your sales.

    By the way, great information Diana, thanks for sharing :)

    Open rates are the first step, converting readers to buyers the second.

    The real measurement of success for any ezine is how much you sold per subscriber, e.g. the total dollar amount of sales divided by the number of people on your mailing list.

    Keep the end in mind to reach your goals.

    Hi:

    Great info. Thanks for sharing it.

    I was actually quite surprised to find that my open rate is more than double the average. I guess I must be doing something right, so I thought I’d share.

    I’ve had an ezine for about 10 years. Initially subscriptions were fed from my only website. Later I kept splitting off and starting new websites as one area on the main site became more specialized and large enough to warrent it’s own focused site. Anyway, I now have 7 websites that all feed subscribers to the one newsletter.

    When I made the move to Aweber back in 2004 (I think), I lost half my list becuase they had to verify etc. I’ve since regained and then exceeded those original numbers.

    The ezine in monthly and it contains at least 80% content - articles, tips, etc. Because of the length of the ezine, I decided that the "ads" were probably getting lost. I wasn’t making many of sales.

    I rewrote all my autoresponders. The first three happen in fast succession. They are just follow ups thanking them for joining and making sure they got the links to the free ebooks I give away for subscribing.

    After that they are sent every 21 days. No idea why I picked that number, but it seems to work. I alternate the autoresponders between a link to read a great article on one of my sites and a sales letter focused on only 1 product or service. My sales have increased dramatically with this method.

    When the autoresponder is a focused sales letter, I am also offering a subscriber only discount for that particular product. It is usually a pretty good percentage off.

    My subscribers are alot like me. I greatly dislike daily messages and if I sign up for something and I begin getting anything more frequently that weekly, I typically unsubscribe. I find all those messages annoying and I don’t care how great the information or products are that they are about.

    wave,

    Open rates are tracked using a 1-pixel image.

    When that image is loaded, an open is recorded (the implicit assumption being that for the image to load, someone had to open that message in his/her email program).
