Reliability roundup
Email & marketing reliability over the last 90 days
OutageDeck watches 6 email & marketing providers and records what each one publishes about itself. Every figure below is read from the vendor's own official status feed, rolled up per UTC day. Nothing here is a probe of the service, and nothing is a user report.
Durations are how long a vendor had something open, not how long anyone was unable to work. The headline figure is time free of major outages: counting a months-long regional event as flat downtime produces numbers no reader believes, so partial and regional impact is reported beside it instead of folded into it.
