Is your email set up to send?
Type your domain. We check the four records behind every email you send, then tell you what to fix and how.
Questions
My emails bounced. Is my setup broken?
Not always. A bounce is often a full or closed mailbox on the other side, or a typo in the address. That is why bounces aren't part of this check. If all four records here are good, your side is set up.
What is a DNS host?
The place that holds your domain's settings, usually where you bought the domain: GoDaddy, Namecheap, Cloudflare and so on. Look for DNS, DNS records or Zone editor.
How long do changes take?
Usually under an hour. It can take up to 48 hours. Check again here once you've made a change.
Do I need all four?
Yes, if you send outreach. MX gets you replies, SPF and DKIM prove the mail is yours, and DMARC ties them together. Gmail and Yahoo ask every sender for SPF or DKIM, and bulk senders for all three.
