Mailbox providers


The other day I tweeted that I often used the term “receivers” to describe receiving MTAs.

A number of folks chimed in and the clear consensus was that the term most people used was “mailbox provider.”

The big problem I have for mailbox provider is that when we’re talking about filtering, or reputation, mailbox providers are not a monolith. Providers have different ways of filtering mail and that’s relevant to some discussions.

But, for now, I’ll use mailbox provider instead of receiver.

  • This is a common issue in the Deliverability world, non-standardized terms, and terms that don’t necessarily encompass what they are intended to mean. It creates an artificially high barrier to entry for understanding.
