Check your domain's email deliverability configuration in seconds. We'll analyze your SPF, DKIM, DMARC, and MX records.
SPF tells receiving mail servers which IP addresses are authorized to send email from your domain.
DKIM adds a digital signature to your emails, proving they haven't been tampered with in transit.
DMARC ties SPF and DKIM together, telling receivers what to do with emails that fail authentication.
MX records specify the mail servers responsible for receiving email for your domain.
