Automated Mailjet Bounce Rate Monitoring

Every morning, WebRun opens Mailjet, reads the delivery stats for each campaign sent in the last day, writes the open, click, bounce, spam and unsubscribe numbers into a Notion database, and texts you through Twilio when a send breaks the thresholds you set.

In short

How do I get alerted when a Mailjet campaign has a high bounce rate?

WebRun opens Mailjet every morning, reads the delivery, bounce, complaint and unsubscribe numbers for every campaign sent in the last day, logs each one as a row in your Notion database, and texts you through Twilio only when a send breaks the thresholds you set.

  • A bad send is caught the next morning, not at the end of the month
  • Every campaign's stats are logged in Notion without copy and paste
  • Sender reputation problems surface before the list is damaged

Good to know

Questions, answered

Will it text my subscribers?

No. The Twilio message goes to your own phone number and nobody else. WebRun never contacts anyone on your Mailjet list, and it never sends, pauses or deletes a campaign on its own.

What counts as a bad send?

You set the thresholds, for example a hard bounce rate above 2 percent or a complaint rate above 0.1 percent. WebRun also compares each send against the running average of your last ten campaigns and flags anything clearly worse.

What happens on a quiet day with no sends?

Nothing is logged and no text goes out. WebRun stays silent when there is no campaign to read, so a message always means a real send needs your attention.

Put this on autopilot.
