Free tool
Do your e-mails reach the inbox?
Give your domain or an e-mail address: the tool reads the SPF, DKIM, DMARC and MX records, and tells you what is missing for Gmail and Outlook to trust your site’s e-mails.
Only public DNS records are read. No e-mail is sent, and nothing is kept.
A domain (your-site.com) or an address (hello@your-site.com).
The name before ._domainkey, given by your e-mail provider.
What the tool looks at
- SPF: the servers allowed to send on the domain’s behalf, and what happens to the others.
- DKIM: the signature proving an e-mail was not altered, looked up under common names.
- DMARC: the rule applied to e-mails imitating the domain, and the reports.
- MX: the servers that receive the replies.
