Deliverability
Graymail
Legitimate email that recipients signed up for but no longer engage with, often filtered or ignored.
Definition
Graymail refers to emails that recipients have technically opted into but rarely engage with. Examples include newsletters they've lost interest in, promotional emails from past purchases, or alerts they no longer need. Unlike spam, graymail is legitimate, but low engagement can hurt sender reputation. Managing graymail involves sunset policies for unengaged subscribers.
Pro Tip
Identify and re-engage or remove graymail recipients before they hurt your sender reputation or mark you as spam.
