Three steps to know the truth about your emails

01

Get your probe addresses

Sign up and receive unique test email addresses at Gmail, Outlook, Yahoo, and other major providers. Real mailboxes, not simulations.

02

Send your email

Fire off your campaign, newsletter, or transactional email to the probe addresses. Use your actual sending infrastructure.

03

See where it landed

MailProbe checks each inbox automatically. Inbox, spam, promotions tab, or missing entirely. Clear visual breakdown, no ambiguity.

Most tools guess. MailProbe checks.

Real inboxes, real answers

No spam score approximations. MailProbe uses actual mailbox accounts at each provider to check where your email physically arrived.

Multi-provider coverage

Gmail, Outlook, Yahoo, iCloud, GMX, and more. One test covers every provider your recipients use.

Spam header analysis

See the raw spam headers from each provider. Understand exactly why a provider flagged you, not just that it did.

Visual, instant results

No CSV downloads or technical dashboards. Clean visualizations that show your deliverability at a glance.
