How to Use the Email Deliverability Tool in cPanel

cPanel includes a handy one-stop panel called Email Deliverability that checks the three records mail providers look at before trusting your messages — SPF, DKIM and reverse DNS (PTR) — and flags anything wrong. If your outgoing mail keeps landing in spam, this is the first place to look.

What it checks

SPF — confirms your domain authorises this server to send mail.
DKIM — adds a cryptographic signature proving messages were not altered.
PTR / reverse DNS — links the sending IP back to a valid hostname.

Green ticks mean you are in good shape; a warning icon means something needs attention.

Step 1: Open the tool

Log in to cPanel.
Under the Email section, click Email Deliverability.
Find your domain and read the status column.

Step 2: Fix any warnings

If a domain shows problems, click Manage beside it. cPanel shows exactly which record is missing or incorrect, and — when the DNS is managed here — offers a Repair button that adds the correct SPF and DKIM records automatically.

If your DNS is hosted elsewhere (for example at Cloudflare), cPanel shows you the exact values to copy across manually. Our guide on adding SPF, DKIM and DMARC records explains each one.

Step 3: Re-check and test

After repairing, wait for DNS to propagate, refresh the page, and confirm the ticks turn green. Then send a test email to yourself at another provider and check it lands in the inbox, not spam.

Frequently asked questions

My records are green but mail still goes to spam.

Authentication is only part of deliverability. Content, sending history and IP reputation matter too. Our guide on why emails go to spam covers the rest.

What is a PTR record and can I fix it myself?

A PTR (reverse DNS) record maps the server IP back to a hostname. On shared hosting we manage this for you, so if it flags a problem, open a support ticket and we will sort it.

Should I add DMARC too?

Yes — DMARC builds on SPF and DKIM and improves trust further. The Email Deliverability tool focuses on SPF, DKIM and PTR, so add DMARC separately using our records guide.
