I just deployed a hack that lets you pull bounces from your estonia phone number material Gmail account so that future GMass mail merge campaigns skip sending to those bounced addresses.

You already get ridiculously high email delivery rates when using GMass, but avoiding repeatedly sending to bounced addresses will optimize your email delivery even further.
This is a hack, and in time we will release a better bounce handling mechanism. For now though, here’s how to pull your bounce list and prevent GMass from sending to past bounces:
1. Use the Gmail search tool toen search. This will show all of the bounce notifications you’ve received.
