Communication & Messaging monitoring FAQ

Which messaging and email providers does PulsAPI monitor?

PulsAPI covers the communication APIs teams rely on, including Twilio, SendGrid, Mailgun, Postmark, Vonage, Sinch, Plivo, Slack, Discord, and Microsoft Teams. Each is checked every 60 seconds against its official status page.

Why does messaging uptime matter for authentication?

If your SMS or email provider is down, one-time passcodes never arrive and users cannot log in. Monitoring those providers as a dependency lets you detect the outage and switch to a fallback channel before sign-ins start failing.

Can I route messaging-provider alerts to the right team?

Yes. Alert rules let you send a Twilio or SendGrid incident to the team that owns notifications while keeping other vendors on separate channels, so the right engineers respond without alerting everyone.
