Email Health Checker от Hassan

Check any domain's email deliverability setup in one click. Email Health Check by MailAfiniti inspects the three records that decide whether your messages land in the inbox or get flagged as spam — SPF, DKIM, and DMARC — and tells you exactly what's wrong and how to fix it.

What it checks

• SPF — Is your sending domain authorized?
• DKIM — Are your messages cryptographically signed?
• DMARC — Do you have a policy telling receivers what to do with failures?

Who it's for

• Founders and marketers debugging why cold emails go to spam
• Agencies auditing client domains before campaigns
• IT teams verifying tenant configuration after a migration
• Anyone curious whether their domain is set up correctly

How it works

Type a domain, click check. The extension calls the public MailAfiniti API to perform live DNS lookups and returns a plain-English report with pass/fail status and remediation steps for each record. No account required. No tracking. No data stored.

Built and maintained by MailAfiniti — the email deliverability platform trusted by senders who care about reaching the inbox.
