# Email verification

The Murlist email verification tool helps to validate the existence of a mailbox before attempting to send emails. This helps you avoid bounce, maintain a good sender reputation, and maximize the ROI on cold email outreach. \
We added this feature to help unify important steps to sending a successful campaign under one roof.

#### Ways to verify email:

There are just two ways to verify an email list, the email verification search bar, and the upload email list method. The email verification search bar is primarily for verifying emails one by one. Only the resulting message is returned.\
Bulk upload on the other hand allows you to verify an email list using csv. 

### Single email verification with search bar:

### Bulk email verification:

To verify an email list, upload a CSV by clicking on the upload list button and following the guide:

![](/files/hbw3fv05WAKk3i1mEnG4)

The lists you uploaded here can be used to create a campaign. You can launch a campaign to only send to prospects who pass the verification or to all prospects.
