Why is my SendFox domain validation not working?

Q: How do I know my domain is validated?

Go to Settings → Email domains. A validated domain shows a Verified label with a Re-check button; a domain that still needs work shows a Verify button.

Validation fails when DNS hasn't updated, a Host value repeats your domain or Cloudflare proxies a record. Fix it, then click Verify in Settings → Email domains.

Domain validation works on every plan, including Free. Until your domain shows as Verified, your emails send from mail@sendfoxmail.com — see why your emails are sent from mail@sendfoxmail.com.

Why does domain validation fail?

1. Have the DNS changes taken effect yet?

DNS changes can take up to 24 hours to propagate, depending on your provider. Wait, then click Verify again. If validation still fails, SendFox says “We weren't able to validate the domain. Please check your DNS settings and try again.” and shows the specific record that failed under each CNAME row on the Verify domain page — fix only what's flagged.

2. Is your DNS host adding your domain to the Host field?

DreamHost, NameCheap, Google, GoDaddy, and some other providers require the Host without your domain (e.g. sendfox instead of sendfox.yourdomain.com). See validating your domain at GoDaddy, NameCheap, DreamHost or Google.

3. Are the records proxied in Cloudflare?

If your DNS is on Cloudflare, set each of the three CNAME records to DNS only (gray cloud), not Proxied. Proxied records can't be verified.

4. Was a value mistyped?

Use the copy buttons next to each Host and Data value on the Verify domain page instead of typing them by hand, and make sure no extra spaces were pasted in.

5. Did the domain sit unverified for a long time?

Records for a domain that stays unverified for about 30 days expire on the email provider's side. SendFox recreates them automatically when you open the domain's Verify domain page, so check that your DNS records match the values shown there, update any that differ, and click Verify.

Only if you see "This domain's DNS records are no longer available. Please delete and re-add the domain to get fresh records." do you need to click Remove next to the domain, add it again with Add domain, and copy the new CNAME values into your DNS.

6. "Please try again in a couple of hours."

The validation service couldn't be reached — this is temporary. Try again later; your DNS records don't need changing.

7. "Sorry, this domain is unavailable."

The domain is already validated by another SendFox account. If you own the domain, contact the SendFox team at support@sendfox.com.

Still stuck? More troubleshooting tips

Some DNS providers don't let you add CNAME records on certain plans or domain types — ask your provider how to add CNAME entries.

Frequently Asked Questions

How long should I wait before retrying?

Up to 24 hours after changing DNS records, though many providers propagate within minutes.

Two records validate but one fails — why?

Each CNAME is checked separately, and the failing one is flagged on the Verify domain page. Check that record for a Host-column issue or a typo, fix just that record and click Verify again.

Do I ever need to re-check my domain?

If you change DNS hosts or delete the records, validation can break — the Re-check button on the Email domains page checks your records again anytime.

How do I know my domain is validated?

Go to Settings → Email domains. A validated domain shows a Verified label with a Re-check button; a domain that still needs work shows a Verify button.
