SPF Check
Sender Policy Framework is an email authentication method that helps prevent unauthorized senders from using your domain to send email. By publishing an SPF record in your DNS, you specify which mail servers and services are allowed to send messages on your domain's behalf.
DKIM Check
DomainKeys Identified Mail is a protocol that contributes to DMARC compliancy and allows a company to take responsibility for sent messages that can be verified by mailbox providers. It enables the outbound domain to digitally sign email to provide legitimacy for the recipient. In conjunction with SPF, DKIM significantly increases your email delivery rates, and setting it up for your domain is a requirement to become DMARC compliant.
DMARC Check
Domain-based Message Authentication, Reporting, and Conformance is essential for protecting your domain from spoofing and phishing attacks. It helps prevent attackers from impersonating your business, safeguards your brand reputation, and improves email deliverability. DMARC provides visibility into who is sending email on your behalf and allows you to instruct receiving mail servers on how to handle messages that fail authentication.
BIMI Check
BIMI is an email standard that allows verified brand logos to appear next to authenticated emails in supported inboxes. By showing a trusted visual identifier, BIMI helps recipients quickly recognize legitimate messages and builds confidence in the sender.
