SPF & DKIM Checker

Check whether your domain has SPF, DKIM, and DMARC set up correctly — the three records that decide whether your email lands in the inbox or the spam folder.

Have a DKIM selector? Add it for an exact check (optional)

DKIM selectors are unique to each sending service. If you leave this blank, we'll probe the most common selectors — but the surest way to confirm DKIM is to enter the selector your provider gave you.

Not passing? We'll set it up for you.

Audienceful generates the exact SPF, DKIM, and DMARC records for your domain and verifies them for you — so your email is authenticated from day one. Read SPF, DKIM & DMARC explained or our custom domain setup guide.

This tool reads public DNS records. DNS changes can take time to propagate, so a record you just added may not appear immediately.
