Live Email MonitoringYour emails don’t stop after you hit send. Neither do we.
Validity Engage watches every email you’ve deployed—around the clock. The moment a link breaks, an image dies, or a client update breaks your render, you’ll know before your subscribers do.

What’s includedProtection that doesn’t clock out when your campaign ships.
Engage keeps watching every email after it leaves your ESP, so issues that surface in the wild reach you before they reach your subscribers.
Continuous render monitoring
Engage re-checks how your deployed emails render across major clients on an ongoing basis.
Broken link & image detection
Engage craws links and hosted images in your live emails around the clock—and flags you the moment one breaks or 404s.
Post-send authentication monitoring
Engage continuously verifies SPF, DKIM, and DMARC alignment on your live sending domains and flags alignment issues as they happen.
Instant alerting
Updates and issues are routed to email or Slack, so a broken campaign gets fixed in minutes—not after the complaints roll in.
Client update re-checks
Engage auto-checks your live emails against new rendering rules the moment a mailbox client ships an update—and flags anything broken.
Monitoring history & audits
Every check, alert, and resolution is logged, giving you a full timeline of how each campaign performed in the wild and proof of when issues were caught and fixed.

Monitor the health of your sent emails by using a platform like Validity Engage to continuously check each campaign after it leaves your email service provider. The program you choose should:
- Re-check rendering across all the big email clients.
- Crawl live links and hosted images to look for errors.
- Verify sender authentication alignment.
- Re-test emails when mailbox clients update their rendering rules.
- Route issues to an email or Slack account so the team knows immediately.
When you get an alert, identify the specific email and the component within that email that was flagged. Correct the issue immediately and run another check to make sure it's resolved.
To monitor email inbox placement, run a placement test before each campaign, then compare inbox and spam folder results by mailbox provider, IP address, and sending domain. If your placement drops, you can improve it by:
- Identifying the affected provider, IP address, or domain.
- Reviewing your Sender Score and blocklist status.
- Checking your Sender Policy Framework, DomainKeys Identified Mail, and Domain-based Message Authentication, Reporting and Conformance alignment.
- Investigating any spam traps, bounces, and complaint patterns.
- Correcting the issue and rerunning the test.
Set up immediate alerts for issues that can disrupt an email campaign you've sent, like:
- Broken links or 404 errors.
- Missing or unavailable hosted images.
- Rendering changes after an update.
- SPF, DKIM, or DMARC alignment failures.
- Inbox placement or Sender Score declines.
- Blocklist activity that affects an IP address or domain.
Route alerts to an email inbox or communication channel that your team actively monitors. Assign an owner and document the resolution so each alert leads to a faster response.
