Resend SLA: What You Need to Know
Resend guarantees 99.95% uptime measured as server uptime for resend's email sending infrastructure (api and smtp availability). This commitment applies exclusively to Enterprise (custom contracts for 3M+ emails/month) plan customers — other tiers have no contractual uptime guarantee.
Based on DevHelm's continuous monitoring, Resend currently shows a 30-day measured uptime of 100.00%. This meets their published SLA commitment of 99.95%.
What's Covered (and What Isn't)
Resend's SLA specifically covers server uptime for resend's email sending infrastructure (api and smtp availability). It explicitly excludes: Free, Pro, and Scale tiers; email deliverability to recipient inboxes (distinct from platform uptime); downstream provider outages. This means outages in excluded components don't count toward SLA credits.
Impact on Your Application
At 100.00% uptime, you can expect approximately < 1m of cumulative downtime per year from Resend alone. 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 Resend'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.
