What are SPF, DKIM and DMARC, and do I need them? Print this Article
Short answer: they're DNS records that prove your email really comes from you, so it lands in inboxes instead of spam. Yes, you need SPF and DKIM. You can check them in cPanel under Email Deliverability.
What each one does
- SPF lists the servers allowed to send email for your domain.
- DKIM adds a digital signature to each email, so the receiver can tell it wasn't changed.
- DMARC tells other mail servers what to do with email that fails SPF or DKIM.
Check yours
- Log in to cPanel. See "How do I log in to my hosting control panel (cPanel)?".
- In the Email section, click Email Deliverability.
- Look at your domain's status.
If the page shows a problem, open a support ticket and we'll help.
If you also send from another service
If you send mail through Microsoft 365, Google or a newsletter tool as well, your SPF record must include them too. A domain should only have one SPF record. Ask us before you add a second.
If it still doesn't work
If your mail goes to spam, open a support ticket with the sending address and a copy of a bounced or junked message.
To send us the right details first time, see "How do I open a support ticket, and what should I include?".
