Email is business-critical, and it breaks quietly. Watch sending and receiving together with SMTP, POP3 and IMAP monitors, plus the DNS and certificate checks mail depends on.
Mail depends on several moving parts: the server that sends, the servers that receive and let people read, DNS records that route messages and certificates that secure them. Any of them can fail on its own.
Monitoring the whole set in one account means one alert list, one status page and one place to see what broke and when.
Every check is stored in a full log, so you can see exactly when and how something changed.
SMTP monitors check that your outgoing server accepts connections.
POP3 and IMAP monitors confirm mailboxes are reachable.
A DNS monitor watches MX and related records.
An SSL monitor warns before mail certificates expire.
From sign-up to your first alert in a few minutes.
