Postgun

Thousands of emails. Each one addressed by name.

Import your list, design the email, attach a different certificate to every recipient, and send it through your own Mailgun account. Postgun handles batching, retries and unsubscribes.

Your Mailgun, your reputation

A file for every person

Import CSV or Excel, use {{merge_tags}}, and attach each recipient's own certificate or ticket.

Clean lists

Every email gets an unsubscribe link. Mailgun bounces and complaints are skipped automatically.
