Why your business emails go to spam, and how to fix it

Short answer: Mail goes to spam when the receiver cannot trust it. Set up SPF, DKIM and DMARC, send from your own domain and avoid spam-like words.

  1. 1Use your domain
  2. 2Add SPF
  3. 3Turn on DKIM
  4. 4Add DMARC
  5. 5Test

When a customer says “I did not get your email”, it is often in the spam folder. Mail providers ask one question: can we trust this sender? Help them say yes.

How the check works

Fix it in 5 steps

Tap a step to open it.

1 Send from your own domain

Use name@yourbusiness.com, not a free address, when you send business email. Send from the mailbox that belongs to your domain.

2 Add SPF

SPF is a note in your domain settings that lists who may send mail for you. In cPanel, open Email Deliverability and follow the repair suggestions it shows.

cPanel, then Email Deliverability. A domain shows Valid when SPF and DKIM are set. Use Manage to see the records.
3 Turn on DKIM

DKIM adds a signature to each email. It is also in Email Deliverability in cPanel. If it says the record is missing, use the repair button.

4 Add DMARC

DMARC tells receivers what to do when a check fails. Start gently: add a DMARC record with the policy none and watch. Tighten it later.

5 Test and keep it clean

Send a test message to a free mailbox and open Show original to see if SPF and DKIM say pass. Avoid ALL CAPS, too many links, and buying email lists.

Domain changes can take some hours to reach everyone. Test again the next day.
