What do the colours in every result mean?

What the green, amber, red and grey statuses on an email mean, and what to do with each one.

Written by Tomba.io Team

The colours tell you how safe an email is to send to. Green means send, amber or grey means take care, and red means don't send.

Each email also has a score from 0 to 100. The higher the score, the more likely your email is to be delivered. In Domain Search, hold your pointer over the score to see the status.

What each status means

Badge

Status

What it means

Green

Valid

The mailbox exists and accepts mail.

Amber

Accept-all

The company's mail server accepts mail for any address, so we can't confirm this mailbox.

Amber

Risky

We can't confirm that mail will be delivered.

Amber

Webmail

The address is on a personal mail service, such as Gmail or Outlook.

Grey

Unknown

The check didn't give an answer, because the mail server blocked it or didn't reply.

Red

Invalid

The mailbox doesn't exist.

Red

Disposable

The address is on a throwaway mail service.

Unknown can also show in amber, when the score is in the middle of the range.

What to do

  • Green: Send.

  • Amber or grey: Send with care, or verify again later.

  • Red: Remove the address from your list.

If you think an address is badly typed, run it through Verify. The Format Validation check shows whether it's written correctly.

💳 Credits: Verifying an email uses 1 verification credit. You aren't charged when the result is Unknown or Disposable.
