Mailgun vs SendGrid: reliability, measured

Current state and a 12-month uptime record for both, from RealUptime's own independent probes. This is a factual side by side, not a recommendation: it never ranks or scores either service, and states no opinion on which to choose.

Full live status and region detail

Composed by the same rule each service's own page uses, with the same omission that page's dependency-stack view carries: user reports, public chatter and each vendor's own status-page claim are not read here, only our probes' own readings.

12-month record

Mailgun

Tracking Mailgun since Aug 22, 2026. In that time our probes detected no outage. Months before that date are not tracked and carry no figure.

Uptime here is the share of each month in which our probes had no outage open for Mailgun: two consecutive failed readings from a region opens one, the first clean reading closes it. Any detected outage counts, including one seen from a single region, and an outage that crosses midnight on the first of a month is counted in both months with its minutes split. User reports, public posts and Mailgun's own status page contribute nothing to these figures.

SendGrid

Tracking SendGrid since Aug 22, 2026. In that time our probes detected no outage. Months before that date are not tracked and carry no figure.
