Automated MailerLite Bounce Rate Alerts
Every hour, WebRun opens MailerLite, checks the bounce and spam complaint rate on recently sent campaigns, logs the numbers to Airtable, and posts an alert page in Notion the moment either rate crosses the threshold you set.
How do I get an early warning when a MailerLite campaign's bounce rate spikes?
WebRun checks your MailerLite campaigns every hour for bounce and spam complaint rates, logs each result to Airtable, and posts a Notion alert the moment either rate crosses the threshold you set. That gives the team an early warning on sender reputation problems instead of finding out after inbox placement drops.
- Sender reputation problems get flagged within the hour, not after the next send
- Every campaign's bounce and complaint rate is logged automatically for trend tracking
- The team spends time fixing the cause instead of hunting for the numbers

Questions, answered
Will it pause a campaign or change my list automatically?
No. WebRun only reads bounce and complaint rates and reports them. It never pauses a send, removes subscribers, or edits list settings on its own.
What counts as a threshold?
Whatever bounce and complaint rate you set. WebRun compares every recent campaign against that line and only alerts when one is crossed.
How fast will I know about a bad send?
It checks every hour, so a spike is usually logged and flagged in Notion within an hour of the numbers moving in MailerLite.
