Email deliverability checker

Your welcome emails, password resets and magic links all depend on these three DNS records. Paste a domain, an email address or a URL — whichever you have.

About the email deliverability

Check a domain's SPF, DKIM and DMARC records, the three DNS records that decide whether your welcome emails, password resets and magic links reach the inbox or land in spam. Paste a domain, email address or URL and get a score out of 100, what each record says, and a copyable fix for anything missing. Your MX records are listed too.

How to use it

  1. Enter your domain, an email address on it, or a URL.
  2. Press Check and wait for the report.
  3. Read each record's status: green passes, amber is a warning, red is missing or broken.
  4. Copy any suggested record into your DNS provider, then check again once it has propagated.

Questions

How do I check if my SPF record is correct?
Enter your domain and look at the SPF row. A domain must have exactly one TXT record starting with v=spf1, and it should stay within SPF's limit of 10 DNS lookups or receivers treat it as an error.
Why can't it find my DKIM record?
DKIM records live under a selector name chosen by your email provider, and DNS has no way to list them. The checker tries the selectors common providers use, so a miss can mean your provider uses a different one.
Do I need DMARC?
Since 2024, Gmail and Yahoo require a DMARC record from bulk senders, and it helps every sender's deliverability. A record at _dmarc.yourdomain.com with p=none is the usual starting point.
How long do DNS changes take to show up?
Often minutes, but up to the record's TTL, and occasionally longer, before resolvers see the new value. Check again later if a record you just added is not found.
