The mailbox exists and accepts mail. Send with confidence, the address is deliverable.
The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.
The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.

220 rkamtaext01.roche.com ESMTP Smtpd; Sun, 31 May 2026 17:10:53 GMTYes. roche.com is a valid email domain, operated by Roche Holding AG. Addresses are persistent and real mail reaches a genuine recipient. Individual mailboxes still go stale, so verify each one before you send.
A live SMTP handshake connects to Roche.com's mail server and asks whether the mailbox exists using the RCPT TO command, without ever transmitting a message. The recipient never sees the check.
Each address runs through 30+ checks including SMTP existence, catch-all detection, role-account filtering, and disposable matching. The same engine has verified billions of addresses since 2012.
Every unverified address is a gamble. Here is what happens when you skip verification and mail a list that has not been cleaned.
People leave companies. Verification flags roche.com mailboxes deactivated since you collected them.
Expired or full roche.com inboxes hard-bounce. A live SMTP check catches them before you hit send.
