Set up an SPF record

Add or update the SPF record that authorizes us to send on behalf of your domain. SPF (Sender Policy Framework) is a DNS record that lists the mail servers allowed to send email using your domain. When ours is included, receiving servers can verify that Broadcasts really come from an authorized source, which improves delivery and reduces the chance of your messages landing in spam.

Before you begin​

  • Administrator access to your domain's DNS zone (or a colleague who can add TXT records for you).
  • The exact SPF include value we ask you to add — copy it from your account's sending-domain or authentication settings (confirm the exact value in your account).
  • A note of any existing SPF record on the domain. A domain may have only one SPF record, so you will edit the existing one rather than add a second.

Steps​

  1. In your DNS provider, look for a TXT record on the sending domain that begins with v=spf1.
  2. If no SPF record exists, create a TXT record with the value v=spf1 include:<our-spf-value> ~all, replacing <our-spf-value> with the value from your account.
  3. If an SPF record already exists, edit it and add include:<our-spf-value> before the closing mechanism (the ~all or -all at the end). Keep every existing include so your other senders still work.
  4. Save the record. DNS changes can take from a few minutes up to 48 hours to propagate.

Result​

Your domain now authorizes us to send on its behalf. Once propagation completes, run an SPF lookup (or send a test Broadcast to a monitored inbox and check the message headers) to confirm the record resolves and passes. If your account shows a domain-authentication status, it should move to verified (confirm the exact indicator in your account).
