Mailgun SLA: What You Need to Know
Mailgun guarantees 99.99% uptime measured as monthly uptime for api, smtp, and outbound delivery services. This commitment applies to all customers.
Based on DevHelm's continuous monitoring, Mailgun currently shows a 30-day measured uptime of —. Uptime data is still being collected for a complete assessment.
What's Covered (and What Isn't)
Mailgun's SLA specifically covers monthly uptime for api, smtp, and outbound delivery services. It explicitly excludes: Mailgun Optimize offerings (deliverability suite) are explicitly excluded from the uptime SLA. This means outages in excluded components don't count toward SLA credits.
Impact on Your Application
Once sufficient monitoring data is collected, this section will show projected annual downtime. If your application depends on additional services, their independent failure probabilities compound — making dependency monitoring essential for maintaining your own SLA commitments.
Monitoring Methodology
DevHelm tracks Mailgun's official status page continuously and aggregates component-level status data into uptime percentages. Data is refreshed every 5 minutes. Uptime is calculated as the percentage of time all components report operational status.
