Lots of email deliverability advice is being bandied around suggesting to delete unengagers (those who have not opened your email in say a year?) from your email list and that that will increase your delivery rate.
And yes, that is true to some extent. To a larger extent it may not be…
But before I go into why and why not this could or could not be true, let’s take a look at what inspired this little rant: A post on Facebook from a very skilled email marketer. (much smarter than myself)
In a nutshell, of course your open percentage rate went up. You “Physically sent” less email.
Less Email Sent = Higher % Opened – IF (Total Opens remain the same physical number)
Above is Ryan Lee’s email this morning If I don’t download his pixel from AWeber in Outlook? (and I have no reason to since he sends only copy in HTML email–) Should he delete me from his list? Should you be deleting me off your list if I don’t open your images?
While Yahoo and Outlook.com (having replaced Hotmail and all Microsoft mail properties) DO load images by default in the Inbox… Just who is downloading these images? Microsoft, Google or Yahoo? Or your actual recipient? Which brings us to our next question–
Gmail Pre-Fetches Email Images! So Does This Have Effect Where It Is Most Effective- At Gmail
After analyzing Gmail’s Priority Inbox and the Primary tab VS the Promotions tab, not only myself but just about every email marketer have announced “Engagement” as your best chance to be seen in these “Best Inbox” Gmail customizations.
However, since the “automatically display images” default came to Gmail, Gmail began pre-caching images. So does the chance of getting in the primary tab and priority inbox have little or even no effect when it comes to removing un-engagers?
This theory would be the basis for a great test here. I would be thinking:
Does the CTR rate at Gmail correspond with the OPEN rate?
Can we even properly measure engaged VS unengaged users anymore at Gmail?
Paul Myers just pointed out to me that the math most email marketers are using is flawed when talking about Gmail pre-fetched images.
To paraphrase- If pre fetch was causing open rates to be flawed, then there would only be ONE open at Gmail, via pre-fetch? So you would see only one open?
Again anyone is only guessing here. We simply do not have enough data to make a factual decision…
No Immediate Delivery Effect Occurs?
The next question I asked myself is does this have immediate 1 to 1 effect on delivery? Do we see immediate affect like my friend suggested above?
After reaching out to my best delivery peeps, Paul Myers in particular pointed out to me that he doubts any positive or negative change would be seen immediately, going on to say:
“The real measure will be over time. It’s likely to be positive, but the degree of change is uncertain.”
Deleting Hard Bounces?
Yeah, email non existent bounces should be removed. And they should be removed by your mailer application, not by you.
Most mailer apps and software will delete a hard bounce, basically an email address that no longer exists after anywhere from one to three attempts. One hard bounce does not mean the email is dead.
In some mailers like SendGrid you can even remove soft bounces manually, usually an “Inbox full” bounce and I do manually remove Gmail bounces for full inboxes.
You have 15 GB of free storage to share across Google Drive, Gmail, and Google Photos; if your Inbox is at its limit I am removing you.
Deleting the Opt Out / Unsubscribe List?
That will have absolutely no effect on deliverability. But if for some reason you do remove unsubscribes, preserve the list with it’s IP addresses and dates, so should someone later accuse you of sending spam? You have proof of the subscribe process and the associated IP address.
So Let’s Decode Exactly What Is Going On Here:
Okay, so my friend deleted almost 50% of her list. That 50% number may mislead you here, since she also deleted her opt out list. All due to the fact they had not engaged by opening an email in the last 12 months.
And her open rate went up by 5%. The more I try to support this theory, the more I poke more holes in it!
So before making a move like this you should ask yourself this:
- How do you know that unopens simply mean your email was not seen because it landed in the Gmail promotions tab?
- Unless you send email with important images in them, might users of say Outlook that does not automatically download images, mislead you?
- Is your Domain is being filtered due to a blacklist you have no knowledge of?
- Do you often get buried because you sent at a time of day that landed you on page-2 of Gmail by the time they got around to opening up Gmail?
- Is your WordPress install is hacked unbeknownst to you and sending spam and that lands your emails in the spam folder at Microsoft properties as well as Yahoo?
So What Should You Do Next?
If you are considering removing a large part of your list we should take some time to sit down and talk about this– Just you and I. Most email delivery experts will agree, this is a drastic step.
