Free email deliverability check

See in 10 seconds whether your quote follow-ups will reach the inbox — and whether anyone can send email pretending to be your business. We check SPF, DKIM, DMARC and MX.

Enter your domain (e.g. yourbusiness.com), not an email address.

Free, instant, and no email required. Run a check, then sign up for QuoteWon to keep your domain monitored and get alerted if it ever breaks.
