Spam Complaints: How Many Is Too Many?
Email Deliverability - Marc Kline - November 29th, 2007 - Permalink
With some things in life, what is “too much” is quite clear.
Last week, we might have had too much turkey or sweet potatoes, or in the ensuing weeks we might go over our holiday spending budgets. When we hit the scales or balance our checkbooks, we know whether or not we went overboard.
Still, in other cases, we need some guidance on the matter. For instance, if we receive too many spam complaints from subscribers, the deliverability of our messages can really suffer.
But how do we know when we’ve received too many of these?
How to Understand Complaint Rates
AWeber sends complaint reports to our customers forwarded from ISPs when their user’s click the “Mark as Spam” buttons they offer.
With ISPs increasing the priority of their users’ feedback on the deliverability of email messages, too many of these complaints can mean too few of our messages get through to our subscribers.
Seeing a need to set the bar and provide some guidance on understanding the volume of these complaints and when we should be concerned, we’ve published a Knowledge Base article covering what you need to know:
Maintaining Good Deliverability
Use this article as a resource to measure potential issues with your own campaigns. These complaints may be trying to tell us one or more ways we can significantly improve results and avoid issues with our campaigns, so you’ll also find additional information on how to make them.
Fortunately, by using email marketing best practices such as those we talk frequently about on this blog, we should continually find our campaigns in good standing.

Hey Aweber, Thanks for publishing the acceptable rate of
complaints. Is there any way to find out what autoresponder
message results in most complaints by campaign? That message
would be a good one to change first!
Thanks!

Thanks for publishing the full text in your RSS feed. It’s a great timesaver and makes it more likely that I’ll read the entire article.

So out of curiousity - do the service providers do anything to differentiate between someone legitimitly using the "delete spam" button, vs using the spam button as a delete button?
I just finally hit the 1,000 mark on my email list. I’d hate to think that my ability to send emails may be jeopardized because one person uses the spam key as a delete button! And there are times that I receive a spam complaint weeks after sending my previous email - highly indicative of using the spam key as a delete button by those who don’t know better.

Matt,
The complaint reporting doesn’t currently show that, but we are in the process of making some changes to the reporting so that you’ll be able to see that. Stay tuned…
John,
You’re welcome! Hopefully this will make the posts more valuable to our RSS subscribers - and inspire you to discuss more posts in the comments area.
Lori,
ISPs are certainly aware that some people use the "spam" button to clear out their inbox. One complaint isn’t going to cause problems for you. After all, what if you send an email to 10 people and 1 marks it as spam? That’s a 10% complaint rate for that email - but still just one complaint by someone who may have just wanted to delete the email. It’d hardly make sense to start blocking you based on that.
I think it’s worth keeping in mind that real, live, smart people work in ISPs’ postmaster/anti-spam departments — and they spend their whole day trying to separate the email that should get delivered from the spam. Chances are, if we think of something that they should do/try/consider or not do, they’ve already thought of it and either done it, are working on doing it — or came up with a good reason to rule it out.
So if we provide relevant, valuable information to people who are giving us permission to do so, and we make it easy for them to unsubscribe when they want to do that, we shouldn’t run into problems.

"I think it’s worth keeping in mind that real, live, smart people work in ISPs’ postmaster/anti-spam departments — and they spend their whole day trying to separate the email that should get delivered from the spam."
Hey Justin, what world are you living in? With the sheer amount of that sort of activity going on across millions of users day after day, it’s the last thing on their minds to compromise their email and risk getting labelled "easy on spammers."
Sure they might make some attempt but they’re going to err on the side of kicking tail first and taking names later because your or my being upset with them will cause less ripples than a handful of "spam complaints" that cause some wanna-be-a-big-name technews outfit to report on them in a negative light.
I think your customers, who are BUSINESS OWNERS, and RELY on assurances of accuracy and not being tossed due to unearned spam complaints need a little more reassurance than being told there are (questionably) "smart" individuals working at ISPs.
This is our livelihoods you’re talking about here.

Marc,
Thank you for your valuable article. But I needed this information about 1 year back. It is too late now.
I was fed up of receiving spam complaints and about 6 months back I contacted your online support to find out the limit. But I was told that I have to judge myself. Finally I discarded my 8000+ subscribers list.
Now I realize that I was way below the maximum limit of 0.1% (in fact I was getting less than 0.01% complaints).
Well, it is better late than never.

Hi,
Justin said:-
"I think it’s worth keeping in mind that real, live, smart people work in ISPs’ postmaster/anti-spam departments — and they spend their whole day trying to separate the email that should get delivered from the spam."
Well, I’m not so sure. The IP address I inherited on my new dedicated server is currently being blocked by Verizon, Comcast and Outblaze. It was also being blocked by Earthlink, but they have a method whereby you can email them to let them know of the issue, and they were very responsive.
The three others all bounce emails from me from my dedicated server because I’m on their out of date block list! Catch 22.
If I email them from my ISPs email address, I just get the standard form email back "your IP is a known zombied / open relay / blah blah blah" which is complete nonsense, and they’re clearly not even interested in correcting it.
It’s a fully secured cPanel server running only my own domains - the IP address was probably on a block list at some point. (Is it just me or are block lists 2001 technology?)
Until my host can resolve this for me, I have a message saying don’t contact me with these email addresses. Several of my customers have complained on my behalf to their ISPs, and got nowhere.
So, I really don’t think that’s smart behaviour is it? It makes them look a lot less than smart.

Frank and Sam,
My comments were directed toward Lori’s concerns about her AWeber-managed mailing list, and more specifically her concern that a spam complaint here and there would negatively impact her email deliverability.
I certainly did not mean to imply that deliverability issues are a thing of the past; on the contrary, both of your comments have highlighted the challenge that is getting your email to the inbox, and why so many people trust ESPs such as us with their email campaigns rather than attempting to send from their own servers.
Top-notch email deliverability derives from a combination of technical and non-technical aspects. For more on what these are, what your ESP can/should do, and what you can/should do, you may want to snag a free copy of our email deliverability guide.
Sam, I’m sorry to hear that you view ISPs as a group whose approach to email is “kicking tail first and taking names later.” In our dealings with ISPs we don’t find that to be the case. Ultimately those ISPs are accountable to their users (who can easily switch to another provider) to make sure that not only is spam mitigated, but that wanted email is delivered — with so much important business being done by email, false positives carry a high cost.
While I’m sorry that you’ve had some frustrating experiences, I still hold that ISPs are not out to punish email senders, that getting our email delivered is increasingly based on our reputations, and that a key to getting delivered is simply to improve/maintain our good name with ISPs.
Frank, in your case I might suggest contacting the ISP from a web-based address (perhaps even one at that particular ISP) if you’re unable to connect/reach them through your domain’s email address. In some cases ISPs also provide resources/contact information on their websites (example: AOL’s excellent Postmaster page). You also may want to read our post on dealing with false positives.
A few links that I’d like to share:
Google on Sender Reputation (PDF) - pay special attention to the Recommended Policies on page 5.
Carl Hutzler (formerly of AOL’s postmaster dept.) on allegations of certain groups being blocked - worth noting: the first paragraph regarding why blocking occurs. It really is about complaints.
DMNews Interview with Charles Stiles (also formerly of AOL) - skip to the last 3-4 questions to get an idea of how ISPs/postmasters view the marketing community as opposed to spammers. They really do want to make sure that wanted marketing emails get delivered.
You may also want to check out some of the talks/transcripts from this year’s FTC spam summit.
Hope this helps

Like others, I also appreciate this spam complaint breakdown.
I knew, as I decided to publish a newsletter, that some readers would press the spam key to unsubscribe rather than take the "right route."
But that’s okay, because the masses who enjoy reading my news and respond by purchasing products and services is worth the effort.
If you’re an avid marketer, there’s no way you’ll allow the actions of the few overrule positive feedback from the many.

Some marketers simply refuse to accept these email addresses that provide a spam button, especially hotmail and AOL. They will unsubscribe those people themselves to avoid getting these spam complaints.
I have not done this yet but I’m considering it. This week I’ve had two spam complaints relating to a list that has only been in existence for 3 days. I really don’t want to be writing to people who will sign up to my list one day and report me for spam the next.
December 5th, 2007 at 9:22 am
Rosie,
That’s certainly an approach that you might take, though it’s not one I personally recommend.
After all, not only would you be blocking people at those domains who might lodge complaints, but also people who might be good, qualified, engaged subscribers. Why penalize them for preferring to use a webmail address?
There ways to try and minimize spam complaints that don’t involve preventing anyone with an address at a major ISP like AOL or Hotmail from signing up.
For example, you might try a permission reminder ("you’re receiving these tips because you signed up at http://www.example.com on such-and-such date") placed at the top and/or bottom of your messages.
Or you might look at your signup process and make sure people clearly understand what they’ll be getting - and how frequently they’ll hear from you.

well, it’s kind of a joke at my end–but not a funny one. i got an e-mail today from "aweber" listing the number of spam complaints that i just got (which led me to this thread). well, surprise, surprise, i JUST signed up to "aweber" this past week and sent out my mandatory opt-in verification e-mail. i have not yet sent any broadcasts, newsletters, or rss feeds; so the "spam complaints" that i got–all 3–are apparently due to the opt-in verification e-mail that was sent. b/c of the number of leads i sent the opt-in to (~1300), that makes it a 0.23% spam complaint rate which is higher than the 0.1% suggested that we are supposed to stay under.
sooooo, how the heck could this be a reflection upon me or my company??? the "spam complaints" were direclty a result of the "aweber" opt-in e-mail i had to send out to my imported leads…?…kind of frustrating to think about this issue…

Hi Shereen,
I don’t know the specifics of your campaign or subscribers, so I’m speaking in general terms, but here are a few things that could cause your readers to lodge spam complaints about that email:
* Where/how they originally signed up to your list
* How long it’s been since you last emailed them
* (For migrating lists) whether you let them know about the move and the confirm email in advance of moving them
* Wording in the subject/body of the confirm email
* Your "from" address and name - do subscribers recognize it?
Your complaint rate will change over time (for example, as you send more email today/tomorrow/etc without complaints, that number will fall); the key is to do what you can to keep it low over the life of your campaign.
I’ve sent you an email; if you’d like to talk about the specifics of your campaign and how you might minimize your complaint rate, just let me know.

Just curious, is there a way to see WHICH email addresses actually made the SPAM complaints? If we could simply remove THOSE from our lists, that will prevent one recalcitrant member from ruining our "reputation". Is that possible to have as part of the spam reports?
December 19th, 2007 at 9:37 am
Calvin,
As part of the process AWeber uses to receive and report spam complaints, we do also remove the complaining subscriber from your list. This should help to prevent additional issues with repeated complaints.
Occasional or incidental complaints from one subscriber like this should not cause any deliverability issues. But if you see an increasing number of complaints for any given list, you’ll want to take action such as what is described in the above article.

Can anyone help me please?
Most of my mailings are to provide free content for people who have double-opted into my list. Only once in a while do I send promotional emails. Yet it seems the more I try to give people free, as a gesture of goodwill, the more spam complaints that ensue. This only happens using aweber for some strange reason and I use other mailing services that rarely if ever show spam complaints.
Can anyone advise me how to prevent people hitting the Spam button purely for what looks like fun or downright awkwardness. Surely if they sign up for free reports and I sent those free reports, the last thing I should expect is a spam report.
Can anyone help please as I am going out of my mind with frustration?
Thanks so much.

Hi Avril,
It’s hard to say for sure without knowing more about your subscribers/traffic and what kind of subscriber expectations (not only about what content you’ll be sending, but about how often you’ll be doing so) are being set in your form and welcome message.
Take a look at our Knowledge Base entry on spam complaint rates (first brown box in the above post) and what you can do to minimize them, and see how you might apply the tips there to your list.
As for seeming to get more of them on messages sent via AWeber as opposed to other platforms, that’s likely a question of reporting — other platforms you may be using may not report complaints from as many ISPs as we do! Unless you’re doing something different with your AWeber-managed campaigns than you are with other ones, there shouldn’t be any statistically significant variation in the number/ratio of complaints you receive.

I have a small list, that only sends updates for my blog posts.
150 subscribers.
Subscription process, as far as I can tell, conform the (Aweber) book.
Still, it really pisses me off, that whenever a message is sent, only
1 (One) subscribers finds it necessary to file a complaint, causing my
Acceptable Complaint Rate to rise to .68%.
!@#$$%#%&
Is there anything I can do about that? Kick him/her out?
Thanks for any great advice.
