Alert customers via SMS, relay failed notices through SMTP, and label the bounced thread in Gmail when MailerSend reports a hard bounce
Email is hard bounced in MailerSend→Send SMS in MailerSend→Send email in SMTP→Search email in Gmail→Add label to email in Gmail
Handle hard bounces immediately by alerting the customer, logging the event via SMTP, and tagging the Gmail correspondence.
When a message hard bounces in MailerSend, this workflow springs into action. 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.
