2. Generate the DNS records

• Once your domain is verified, go to Settings → Domains again.

• Click the “Set up DNS records” button beside your domain.

• Sender.com will automatically generate:

  • SPF TXT record

  • DKIM (usually via a CNAME record pointing to a selector within ._domainkey)

  • Optionally, a DMARC suggestion Woodpecker+12help.sender.net+12Reddit+12DmarcDkim+2Wikipedia+2Wikipedia+2

3. Add records in your DNS provider

• Log into your domain registrar or DNS host (e.g. GoDaddy, Cloudflare, Namecheap).

• SPF: Add a TXT record at your root domain (example.com) with the exact SPF string provided.

• DKIM: Create a CNAME or TXT record under the label selector._domainkey.yourdomain.com (based on instructions).

• DMARC (optional but recommended): Add a TXT record at _dmarc.yourdomain.com (e.g. v=DMARC1; p=none; rua=mailto:...) Microsoft Learn+7help.sender.net+7DmarcDkim+7Woodpecker+10Wikipedia+10Wikipedia+10

4. Verify and wait for propagation

• After adding the records, return to Sender.com and click “Check SPF/DKIM Records”.

• DNS propagation typically takes 24 to 48 hours.

• Once verified, you’ll see green checkmarks next to SPF and DKIM. If not, click “Recheck DNS records” after waiting. help.sender.net+1support.nmi.com+1

📝 What SPF and DKIM Do

• SPF: An SPF TXT record (starting with v=spf1) specifies which mail servers are allowed to send emails from your domain. Mail providers check this to prevent spoofing. senders.yahooinc.com+15help.sender.net+15Wikipedia+15

• DKIM: Adds a cryptographic signature to your email. The public key is published via DNS and helps recipients verify that the email is authentic and unchanged. Wikipedia

• DMARC: (Optional, but highly recommended) This policy combines SPF and DKIM alignment and tells receiving servers what to do if emails fail authentication. It also provides reporting feedback. YouTube+6Wikipedia+6Reddit+6
