SMTP or security changes
A password rotation, port change, expired certificate or TLS issue can interrupt the sending path.
CONTINUOUS MAILBOX OVERSIGHT
Know when email delivery starts to slip.
A mailbox can work today and lose deliverability tomorrow. Schedule recurring checks in your dashboard to spot SMTP, security, authentication or reputation changes before they disrupt important outgoing email.

INCLUDED WITH YOUR PAID PLAN
Included in paid plans from per month
Recurring deliverability monitoring is included with an active paid subscription. No separate monitoring add-on is required.
SMALL CHANGES CAN HAVE A BIG IMPACT
Email delivery is part of your operations.
SMTP settings, TLS certificates, domain authentication and sender reputation can change over time. A configuration update or a new spam signal may lower a mailbox score without an obvious warning in your application.
Domain authentication drift
Changes to SPF, DKIM or DMARC records can affect how receiving providers evaluate your messages.
Reputation and spam signals
Blocklist listings or other reputation signals may appear after a mailbox was configured and tested.
ILLUSTRATIVE MONTHLY SCENARIO
A campaign that lands in spam can put thousands at risk.
A sending system may accept a message even when a promotion later lands in spam. The sender can see a successful handoff while customers never notice the offer.
4 weekly sends × 1,000 recipients each
80 orders at an illustrative 2% purchase rate
Assumed average value per order
Potential gross sales at risk
If all four campaigns go unseen
80 assumed orders × average order value = gross sales opportunity.
Illustration only, not a forecast, confirmed loss or promise. This is gross revenue before costs. Real inbox placement, conversions and sales vary. Monitoring can surface technical or reputation warnings, but cannot guarantee inbox placement or sales.
MONITOR FROM THE DASHBOARD
A recurring check with a clear next step.
Choose how often MailBridgeAPI should check the connected mailbox, define the conditions that matter to your team, and keep a history of recurring reports beside your other deliverability checks.
01
Choose a schedule
Build a schedule in the dashboard. The shortest interval is 60 minutes, with options to choose the time and calendar cadence.
02
Set your alert threshold
Choose the minimum score that is acceptable for this mailbox. You can also be alerted when a report fails or stays pending for more than five minutes.
03
Review every result
Recurring reports are kept in the deliverability history and identified as automatic, so your team can follow changes over time.
GET THE SIGNAL WHERE YOU NEED IT
An alert should reach the person who can act.
Choose email alerts, mobile push notifications, or both. Email alerts go to your account email by default; you can enter another recipient. The alert includes the reason, mailbox and score, plus report details and a link to the full result.
GET THE SIGNAL WHERE YOU NEED IT
- The score falls below your chosen minimum
- A diagnostic fails
- A report is still pending after five minutes, if you enable that condition
Alerts are sent when a monitored issue is detected; recovery is recorded by later checks. A score is a diagnostic signal, not a guarantee that every provider will place a message in the inbox.
A REPORT, NOT JUST A WARNING
See what failed and what to do next.
The alert email puts the result in context: a color-coded overall status, the mailbox and score, then diagnostic checks ordered by priority. Each check explains the finding and, when available, gives a recommended action. The full report remains one click away.
Failures and warnings appear before successful checks, so the items that need attention are easy to find.
