It’s not marketing, it’s spam

There are times when I hesitate to call what marketers do “spam.” I can use the euphemisms with the best of ’em. “Cold emails” “Targeted Marketing” “B2B marketing.” I’ll say it here and now: cold emails are spam. Sales people who are sending enough email that they require automation to actually send the mail are […]

My question about Gmail engagement is how would I reach someone who has not been opening my emails? Say I want to do a re-engagement campaign. If I temporarily suppress a contact from […]

My domain reputation is bad, should I get a new domain?

Many companies have the occasional “oops” where they send email they probably shouldn’t have. This can often cause a decrease in reputation and subsequent delivery problems.

Undelivered mail without a bounce

A few weeks ago I wrote a blog post focusing on one small part of bounce handling. Today I want to talk about delivery failures that aren’t bounces. This is really the biggest issue for companies who have written their own bulk sending servers.
