The problem
- A nightly job stops running and nobody notices for a week.
- A certificate expires on a Sunday.
- Your app needs to send mail, but you don't want a separate vendor for it.
How vizsu helps
Heartbeats and SSL tracking
Your job pings a URL when it runs. No ping in time, you get an alert. Uptime also warns you before certificates expire.
API checks from several regions
Confirmed by every region before it pages anyone.
API keys and webhooks
Manage Uptime with vgl_* API keys. Send alerts to your own webhook.
Send mail from code
Mail has a REST send API with Idempotency-Key support, plus standard SMTP submission.
How it works
- Create an API key in your vizsu workspace.
- Add a heartbeat or check. Put the ping URL at the end of your cron job.
- Wire alerts to Slack, Discord, Telegram, email or your webhook.
Said plainly
We're a new company with no logos to show. The limits are real and we'd rather say them now: Mail sends to up to 250 recipients per mailbox per 24 hours. It's built for app and team mail, not bulk or marketing sends.

Can I use SMTP instead of the API?+
Yes. Standard SMTP submission works.
Can alerts go to my own system?+
