How to read your Optimizely.com verification result

Every check returns one of three clear outcomes so you know exactly what to do with the address.

Passed - Safe to Send

The mailbox exists and accepts mail. Send with confidence, the address is deliverable.

Failed - Do Not Send

The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.

Unknown - Use Caution

The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.

Can you verify Optimizely.com email addresses?

Verification method

SMTP

A live SMTP handshake connects to Optimizely.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.

Accuracy

99.7%

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.

Why verify Optimizely.com emails before you send?

Every unverified address is a gamble. Here is what happens when you skip verification and mail a list that has not been cleaned.

Catch role changes

People leave companies. Verification flags optimizely.com mailboxes deactivated since you collected them.

Avoid dead mailboxes

Expired or full optimizely.com inboxes hard-bounce. A live SMTP check catches them before you hit send.

Protect sender reputation

Low bounce rates keep you trusted by optimizely.com mail servers and the major mailbox providers.

Keep CRM data accurate

Verified contacts mean your CRM, lead scoring, and routing all run on addresses that reach a person.
