Email Reputation Check
Inspect a sending IP’s blocklist status and your domain’s email configuration.
Know exactly what is checked
- Blocklist status Check the supplied sending IP against supported lists.
- Email configuration Inspect SPF, DMARC and a DKIM record when a selector is provided.
- Reverse DNS Compare PTR hostnames with forward DNS for the supplied IP.
DNS checks describe configuration. They do not verify a message’s authentication or guarantee inbox delivery.
How to get accurate results
- 1Enter your domain
Add the domain you use to send emails (optional). This checks SPF and DMARC, and DKIM when you also enter a selector.
- 2Use the actual sending IP
Enter the IP address that sends your emails (optional). That address is checked against the supported blocklists and reverse DNS.
- 3Add your DKIM selector
Provide your DKIM selector (optional). The published DKIM record is looked up. The selector is not replaced with a default.
Frequently asked questions
Where can I find my sending IP?
Use the IP address of the server that hands the message to other mail servers. The website’s A record and an MX hostname are not automatically that address.
What does a blocklist listing mean?
A listing means that provider returned a documented code for the IP you supplied. Policy listings and spam-source listings are not the same thing. Confirm the provider, the code, and the IP before asking for removal.
Does this check verify email authentication?
No. It reads DNS configuration and selected blocklist responses. It does not evaluate an individual message or guarantee inbox delivery.
Can I check only a domain?
Yes. A domain check covers SPF and DMARC, plus DKIM when a selector is present. Blocklists and reverse DNS wait until you enter a sending IP.
