Atnext mail

You're referring to "at next mail"!

"At next mail" is a phrase used in email marketing and automation to refer to the next email in a sequence or campaign. It's often used in email marketing automation workflows to trigger the sending of the next email in a series, based on certain conditions or actions taken by the recipient.

For example, you might set up an email campaign with three emails, and use "at next mail" to trigger the sending of the second email after the recipient opens the first email, or to trigger the sending of the third email after the recipient clicks a link in the second email.

In other words, "at next mail" is a way to automate the sending of subsequent emails in a campaign, based on specific triggers or actions taken by the recipient.
