What this means. A Verified by MailArrive badge confirms that mailarrive.com’s email is set up to modern authentication and reputation standards — SPF, DKIM, DMARC, a clean sending reputation, and encryption in transit. It is not a judgment of the business or of any individual message; always read the message itself on its merits. See the full standard.
The five checks
SPF validPass
SPF looks good (1 of 10 allowed lookups used).
DKIM provenPass
A DKIM signing key is published in DNS (selector selector1, selector2), so your outgoing mail is cryptographically signed.
DMARC enforcesPass
DMARC is enforced at p=quarantine.
Clean reputationPass
Your domain is clean on the 4 domain blocklists we check, including Spamhaus DBL.
TLS in transitPass
Microsoft 365 handles this domain's mail and delivers it over encrypted (STARTTLS) connections.
