SendGrid SLA: What You Need to Know
SendGrid guarantees 99.95% uptime measured as monthly api availability for the sendgrid mail send api. This commitment applies exclusively to Essentials, Pro, Premier plan customers — other tiers have no contractual uptime guarantee.
Based on DevHelm's continuous monitoring, SendGrid 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)
SendGrid's SLA specifically covers monthly api availability for the sendgrid mail send api. It explicitly excludes: Free trial, Segment Services, Stytch Services. 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 SendGrid 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 SendGrid's official status page continuously and aggregates component-level status data into uptime percentages. Data is refreshed every 30 seconds. Uptime is calculated as the percentage of time all components report operational status.
