What is watched
The live numbers on the Block Clock page: the fee that gets into the next block (sat/vB), how much is waiting to be confirmed (MB), and how long since the last block was found.
How fresh
Checked every 5 minutes.
Messages go to email, Telegram, a webhook, Discord, Slack or your browser.
Your limits
Each alert waits at least 60 minutes before it can go off again. A "no block" alert takes 10 to 240 minutes.
Your account keeps up to 10 alerts on, and sends up to 30 messages a day.
