Email Health Checker szerző: Hassan

Check any domain's email deliverability in one click. Email Health Checker by [https://mailafiniti.com] runs a live SPF, DKIM, and DMARC lookup on any sending domain and tells you why your emails land in spam, plus exactly how to fix it.

If your cold emails, newsletters, or transactional messages keep getting flagged, the cause is almost always a missing or misconfigured DNS record. This extension finds the problem in seconds.

What it checks:
- SPF record check: Is your sending domain authorized to send mail?
- DKIM record check: Are your messages cryptographically signed and verifiable?
- DMARC record check: Do you have a policy telling inbox providers what to do when a message fails?

Who it's for:
- Founders and marketers are debugging why cold emails go to spam
- Agencies auditing client domains before launching campaigns
- IT teams verifying email DNS configuration after a domain migration
- Anyone who wants to confirm their domain is set up to reach the inbox

How it works:
Type a domain, click check. Email Health Checker calls the public MailAfiniti API to run live DNS lookups, then returns a plain-English report with a pass/fail status and step-by-step fixes for each record. No account required. No tracking. No data stored.
