Scale.com

No. scale.com is not a disposable email provider. It is classified as Corporate Email operated by Scale AI Inc. and addresses on scale.com are persistent rather than throwaway. Mail sent to a valid scale.com mailbox reaches a real recipient.

The fastest way to verify a scale.com email address is to use our free email checker. Enter any @scale.com mailbox at the top of this page and our system performs a real-time SMTP handshake against scale.com's mail servers, confirming whether the mailbox exists, is reachable, and is safe to send to. No email is ever delivered during the check.

Yes. Our real-time email verification API connects directly to scale.com's mail server, opens an SMTP session, and queries the mailbox using the RCPT TO command without ever transmitting an actual email. The server's response confirms whether the scale.com mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.

scale.com currently publishes 5 mail exchange (MX) records. The primary MX is aspmx.l.google.com, which is the first server contacted when other mail systems try to deliver email to a scale.com address. The full list with priorities and IP addresses is in the MX Records panel above. MX records tell sending servers where to route email for scale.com.

scale.com enforces all three email authentication standards: SPF, DKIM, and DMARC (policy: quarantine). This is the gold-standard configuration. It means receivers can verify that mail claiming to come from @scale.com is genuine, and scale.com's DMARC policy of 'quarantine' instructs receivers how to handle messages that fail those checks.

Bounces from scale.com usually fall into three buckets: the mailbox doesn't exist (5xx user unknown), the inbox is full, or your sending domain isn't authenticated to scale.com's satisfaction. The fastest fix is to run each address through a free email verifier before you send, and to make sure your own SPF, DKIM, and DMARC are configured correctly so scale.com's receivers trust you.

Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of scale.com addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, scale.com catch-all detection, role-account detection, and disposable-domain matching. Results typically come back within minutes and previously-failed addresses on your blacklist are reprocessed for free. For continuous high-volume needs, see our unlimited email verification API.

Yes, with normal hygiene. scale.com is a legitimate email service and signups from @scale.com behave like any other real user. Pipe each address through a real-time email verifier API at the moment of signup to catch typos and dead mailboxes, but there is no need to block scale.com by default.

Most scale.com mailboxes follow common patterns like first.last@scale.com, firstinitiallast@scale.com, or first@scale.com, but the actual local-part rules depend on Scale AI Inc.. The only reliable way to confirm whether a specific @scale.com address exists is to run it through a free email verification tool. Guessing patterns will produce a high bounce rate and damage your sender reputation.

The 0-to-100 risk score for scale.com combines disposable-domain classification, mail-server reachability, MX record presence and depth, SPF / DKIM / DMARC enforcement, DMARC policy strength, SMTP banner response, and domain age.
