Never 100% inbox

No matter how great an email program deliverability is, no one can guarantee that 100% of the email sent will reach the recipient’s inbox. Why? Recipients can make decisions about where mail goes in their own inbox. Every mail client has a way for users to control where mail is delivered.

This is good for delivery, when the mail means so much to people that they override spam filters and put mail in their inbox. This is problematic for delivery when the final recipient throws mail away or filters it into spam.

Of course, there’s no way to know what individual recipients are doing with mail in general. Sure, there’s currently panel data but that is only for the subset of users that installs a 3rd party app into their mailbox. There’s no way to know where 100% of email is delivered.

For me, I consider any email program with a >95% inbox delivery rate to be an excellent program. I also don’t think there’s much the sender can do in order to get that last 5% to the inbox. That 5% is just not reachable. Not by improving data, not by double opt-in, not by any of the things we do to improve delivery. Some small percentage of mail is just never going to get in front of the user.

The primary reason for these delivery failure is the end user. End users can, and do, create their own filters. While ISPs do curate the inbox, end users have the ability to filter email. If an enduser sets up a filter for a particular email, the ISP isn’t going to overrule that. ISPs want the end users to have a pleasant inbox experience. Thus, the end user’s wants and needs rule. Nothing is clearer to the ISP whether a particular user wants an email than that user directly setting up a filter.

Following CAN SPAM isn't enough to reach the inbox

One of the top entries on the list of things deliverability folks hear all the time is, “But my mail is all CAN SPAM compliant!” The thing is… no one handling inbound mail really cares. Seriously. CAN SPAM is a law that is little more than don’t lie, don’t hide, and heed the no. Even more importantly, the law itself states that there is no obligation for ISPs to deliver CAN SPAM compliant mail.

Collecting email addresses

One of the primary ways to collect email addresses is from website visitors, and it’s actually a pretty good way to collect addresses. One of the more popular, and effective, techniques is through a pop-up window, asking for an address. Users need to provide an address or click a “no thanks” link or close the window. I’ve noticed, though, that many companies drop something passive aggressive in their “no thanks” button. “No, thanks, I don’t want to save money.” “I don’t need workout advice.”

5 Simple Tricks to Reach the Inbox

I saw a post over on LinkedIn today. It was from an ESP, talking about their simple tips and tricks for getting into the inbox. The laughable bit was half the “tricks” had nothing to do with getting to the inbox, but rather were about enticing people to open the mail once it’s gotten to the inbox.
There are no “tricks” to getting to the inbox. There used to be some tricks. But the ISPs figured them out and protect against them.
