About Twilio
Twilio publishes three SLAs (APIs incl. SendGrid Mail Send, Flex Critical Scenarios, Segment Data Ingestion). Support response guarantees carry a credit: if the monthly average response time for a priority exceeds the guarantee, credit equals the support plan fee for that month (claim within 30 days). Business-hour minutes are nominal. Stytch SLA exists only in order forms.
