Find the weak link in your sending domain.

A missing record, incomplete DKIM check or passive DMARC policy can be easy to overlook. MailSlurp brings the findings together so you can see what passed, what needs attention and what has not been checked.

Check authentication

Review SPF, DKIM and DMARC, including whether the DMARC policy is enforced or passive.

Keep unknowns visible

Distinguish warnings, failures and unchecked signals before deciding what needs investigation.

Catch the change. Tell the right people.

Keep checking after the DNS setup is finished. Schedule runs, compare the findings and alert your team when a sending-domain change needs attention.

Send alerts to email, Slack, Microsoft Teams or a webhook. Choose the severity for each destination, then open the affected run to investigate the records behind it.

Connect your existing workflow

Use webhooks to bring findings into the tools your operations team already uses.

See what happened to the email, too.

Pair domain monitoring with an inbox placement test through your real sending provider. Authentication findings help explain the sender; provider results show where the tested messages landed.

How to keep your sending domain in view

Add the domain and run a check

Enter the domain you send from, add the relevant DKIM selectors and inspect the first result. Keep warnings, failures and unchecked signals separate.

Set a schedule and alert destination

Choose how often to check the domain and where your team should hear about changes. Send alerts to email, Slack, Microsoft Teams or a webhook.

Investigate the changed record

Open the affected run and compare it with the previous result. After a correction, run another check and test a representative email's placement. The domain monitoring guide covers setup and findings.

Connect the domain finding to the email it affects.

Check the domain behind your email

A DNS change matters because of what it can do to your next send. MailSlurp keeps the record findings visible, then gives your team inbox placement tests and device previews to check the message itself.

Schedule checks after the first domain review

When evaluating an EasyDMARC alternative, start with a domain and its relevant DKIM selectors. Review the first run, configure a schedule and send alerts to the people who manage DNS. After a correction, rerun the domain check and test a representative campaign.

Questions before you switch?

What should I test when comparing EasyDMARC alternatives?

Add the domain you send from and the DKIM selectors used by your sending services. Run the first check, review failures and warnings, and keep unchecked signals separate from passes. Set a schedule and an email, Slack, Teams or webhook alert so the next record change reaches the right person. See domain monitoring setup.

Which records can I investigate?

MailSlurp brings SPF, DKIM, DMARC, MX, blocklist, BIMI, MTA-STS and TLS reporting findings into domain monitoring. Add the relevant DKIM selectors and review unchecked signals separately from passes.

How does my team hear about a change?

Configure alerts for email, Slack, Microsoft Teams or a webhook. Choose the minimum severity, then open the affected run to investigate the underlying finding.

Keep your sender ready for the next campaign.

Run the domain checks and bring your team into the result.
