What is Email health check and what is it for?
Audits your domain's SPF, DKIM, DMARC and MX records and checks whether your mail server is blacklisted. If your emails don't reach customers or land in the spam folder, the cause is usually not the content but these authentication records being missing or wrong.
Frequently Asked Questions
- Enter your domain.
- Review the SPF, DKIM and DMARC results one by one.
- Fix missing or faulty records from your DNS management panel.
- Check again after the change has propagated.
Yes. SPF defines which servers may send, DKIM proves the message wasn't altered in transit, and DMARC sets what happens when verification fails. Setting up only SPF is one third of the protection.
Don't. Start with none and collect reports, add your legitimate senders, then tighten gradually. Otherwise the email of a service you weren't aware of gets rejected entirely.
The two most common reasons: more than one SPF record on the domain, and exceeding the 10 DNS lookup limit. Removing services you no longer use from the record usually solves it.
Yes, even more so. Domains that don't send are ideal for spoofing; with a strict SPF and DMARC policy you can prevent mail being sent in your name.
Fix the cause first: a compromised account, an open mail relay or unsolicited bulk sending. Then apply through the delisting form of the list in question.
