Check your domain’s email authentication

Enter a domain and this reads its live SPF, DMARC and MX records, counts your SPF DNS lookups against the limit of 10, and tells you what to fix. No account, no email required.

Why this matters for sending

Authentication is the part that decides whether you reach the inbox

Flomailr checks SPF, DKIM and DMARC before every campaign goes out, and refuses the send when something would land you in spam. Suppression, daily caps and quiet hours are enforced on the server, so no setting or integration can talk its way past them.
