The nice folks over at Postmark shared a new deliverability resource last week. The SMTP Field Manual. This is a collection of SMTP responses they’ve seen in the wild. This is a useful resource. They’re also collecting responses from other senders, meaning we can crowdsource a useful resource for email deliverability folks.
Sometimes I find it hard to find a new topic to write about. I decide I’m going to write about X and then realize I did, often more than once. Other times I think I can blog about some issue only to realize that it’s too complex to handle in a quick post. There are concepts or issues that need background or I have to work a little harder to explain them.
One thing I haven’t blogged about before is bounce handling. That particular topic falls into the other category of posts that take a lot of time to write and need a significant amount of work to make sense. I was even joking with my fellow panel members at EEC a few months ago about how that’s a post that so needs to be written but I’m avoiding it because it’s so hard. There’s so much to be conceptualized and explained and I realize it’s not a blog post but multiple blog posts, or a white paper or even a book.
So let’s start with some simple definitions. Those of you who work at ISPs are probably thinking of bounces in terms of accept than reject, that’s not exactly what I’m talking about here. I’m writing these for senders, who usually call rejects during the SMTP transaction bounces.
This week’s Wednesday question comes from D.
What are your thoughts on bounce handling

Bounces and bounce handling is one of those topics I’ve avoided writing about for a long time. Part of my avoidance is because there are decades of confusing terminology that hasn’t ever been really defined. Untangling that terminology is the first step to being able to talk sensibly about what to do. Instead of writing a giant long post, I can break it into smaller, more focused posts.
