A cut above the rest of the Gmail mail merge add-ons available. Super easy to use and a generous free plan. Plus, importantly, it doesn't request permission to read my emails.

Mailmeteor BounceShield verifies 100% of your emails sent via Mailmeteor.

Mailmeteor BounceShield works in real-time, in the background, to verify 100% of your emails. There may be instances where you still receive a bounce, despite verifying the email address beforehand. This could be due to the email being deleted between the time it was verified and when it was actually sent. Also, in some cases, a bounce can only be detected by actually sending an email to the email address.

Bounces happen when you send emails to invalid email addresses. By verifying email addresses before sending emails, you reduce the likelihood of receiving bounced emails. Mailmeteor BounceShield verifies your emails before sending them, so you don’t have to.
