Common DNS hosts

EonMailer and your ESP show the records; the client’s DNS host must publish them. Here’s where to click for the hosts we see most.

Cloudflare

1. Select the domain → DNS → Records.
2. Add record for each CNAME / TXT.
3. For DKIM CNAMEs, set Proxy status → DNS only (grey cloud). Orange-cloud proxy breaks ESP verification.
4. TTL Auto is fine.

Amazon Route 53

1. Hosted zones → domain → Create record.
2. Paste name/value exactly (Route 53 often wants the relative name, not the FQDN — follow the console hint).
3. Record type TXT or CNAME as shown by SES/SendGrid/Mailgun.

GoDaddy

1. My Products → DNS → Manage DNS.
2. Add records; for TXT, put the value in quotes if the UI strips spaces oddly.
3. Propagation can be slow — wait before re-checking in EonMailer.

Namecheap

1. Domain List → Manage → Advanced DNS.
2. Use Host field carefully (@ for apex, s1._domainkey style for DKIM).
3. Save → wait 15–60 minutes.

If IT owns DNS

Export a one-pager from EonMailer’s domain screen (copy records) and ask IT to:

1. Add the records unchanged.
2. Confirm no conflicting SPF (only one SPF TXT on the apex).
3. Reply when live so you can click Re-check in Deliverability.
