About Mailproof

A small, honest tool for people who send email and want to know where it ends up.

Mailproof keeps a set of ordinary mailboxes at popular providers. When you run a test, your message is sent to those mailboxes like to any other recipient, and we report what each provider did with it.

The accounts are created and maintained by our team by hand, following each provider's terms. The service never registers accounts automatically and never interferes with the providers' filtering.

We built it because spam folders are silent: no bounce, no error, just customers who never saw your message.

Providers currently tested

The list changes over time as we add and retire mailboxes.
