Handle hard bounces immediately by alerting the customer, logging the event via SMTP, and tagging the Gmail correspondence.

It immediately sends an SMS to the customer, relays the failed delivery notice to an internal system through SMTP, and finds and tags the matching email thread in Gmail so your team stays informed without manual searching.

Sync MailerSend unsubscribes to your internal suppression relay and mark related Gmail threads to prevent accidental follow-ups.
Keeping your contact lists compliant is critical. This workflow ensures that whenever a recipient unsubscribes in MailerSend, the opt-out is relayed internally through SMTP and the associated email thread in Gmail is clearly labeled, preventing sales reps from contacting the lead again.
