Facts read from this source

• Spf dkim dmarc support Report an error

  “This guide explains how to configure SPF, DKIM, and DMARC authentication records for your sending domain in Sender. Completing all three ensures mailbox providers can verify emails sent through your account.”

• Domain settings path Report an error

  “In the Sender dashboard, go to: Account settings → Domains”

• Dns records Report an error

  “DKIM record: Type: CNAME Name/Host: sender._domainkey Value: dkim.sendersrv.com TTL: 3600”

• Spf record Report an error

  “SPF record: Type: TXT Name/Host: @ Value: v=spf1 include:sendersrv.com ?all TTL: 3600”

• Dmarc record Report an error

  “DMARC record: Type: TXT Name/Host: _dmarc Value: v=DMARC1; p=none; TTL: 300”

• Domain ownership verification Report an error

  “Sender will send a verification email to that address. Open the email and click the verification link to confirm domain ownership. Once verified, a green checkmark appears in the Ownership confirmed column.”

• Dns verification recheck Report an error

  “Return to the DNS records dialog in Sender and click Check SPF, DKIM and DMARC records. Sender will query your domain’s DNS to verify that all three records are correctly configured.”

• Dns propagation time Report an error

  “DNS changes can take up to 24–48 hours to propagate, though most complete within minutes.”

• Single spf record rule Report an error

  “If your domain already has an existing SPF TXT record, do not create a second one. Instead, merge the Sender include into your existing record by adding include:sendersrv.com before the all mechanism. A domain must have only one SPF TXT record to pass validation.”

• Dmarc policy upgrade Report an error

  “You can later strengthen this to p=quarantine; or p=reject; as you gain confidence in your authentication setup.”

• Free email sender warning Report an error

  “Using a free email address as your sender address is not recommended. Most mailbox providers enforce strict DMARC policies on free email domains, which will cause your emails to fail authentication and land in spam or be rejected.”

• Authentication failure consequence Report an error

  “If you modify or remove the DNS records Sender relies on, authentication will fail. Mailbox providers may begin rejecting or spam-filtering your emails.”
