MailVakt

MailVakt helps you troubleshoot email deliverability and authentication directly from Claude. Investigate why emails may land in spam, check your domain’s DNS configuration, and get actionable recommendations for improving email security.

Use MailVakt to:

• Audit email authentication: Check SPF, DKIM, DMARC, MX records and domain alignment, plus BIMI, MTA-STS and TLS-RPT configuration.
• Check blocklists: Look for domain and sending-IP listings on supported free public blocklists.
• Analyze email headers: Inspect reported authentication results, sending IPs and alignment to identify potential delivery problems.
• Generate DNS recommendations: Get proposed email authentication records and provider-specific setup guidance for monitoring or enforcement.
• Test email receipt: Create a test address, send it an email, and inspect authentication, unsubscribe, content and deliverability findings.
• Monitor DMARC reports: Add domains to your MailVakt account and summarize collected aggregate reports, including message volumes, pass/fail counts, sending sources and receiver actions.

Ask Claude: “Check my domain’s email authentication,” “Analyze these email headers,” or “Summarize my DMARC reports for the last 30 days.”

Domain checks, header analysis, DNS recommendations and email-receipt tests work without signing in. Managing domains and viewing DMARC reports require a MailVakt account. Report collection starts after you publish the provided reporting address in DNS.

MailVakt recommends DNS changes for you to review and publish. Email-receipt tests confirm receipt and inspect the message; they do not measure inbox-versus-spam placement at Gmail or Outlook.
