How to verify a sender email address

Improve email deliverability by verifying your email addresses

Email authentication changes coming in February 2024

There’s a crucial update coming our way in February 2024 from Gmail and Yahoo! regarding email authentication. From this time, both companies have required bulk senders to authenticate their email domains.

This means that starting February 2024, it is mandatory to authenticate your domain in Prowly in order to continue sending emails through our platform.

For detailed instructions on how to authenticate your domain in Prowly, please refer to our Help Center article or reach out to our Customer Support team using chat.

To protect your sender reputation and improve email deliverability, we require email verification for all emails that you want to use as a sender.

Here's how to verify your email address in Prowly  

1. Start by clicking the gear icon in the top-right corner

2. Go to Email setup and click the Add new sender button

3. Provide the name and email address and save changes

You will receive a verification email to be able to start email outreach via Prowly.

In the table within the Senders addresses section, you can find details about all your sender emails - their names, email addresses, as well as current statuses of verification and authentication:

account email setup senders

  • Verified - sender has already verified their email address and can send email campaigns via Prowly.
  • Not verified - sender still needs to be verified, and it won't be possible to send out email campaigns using it until it's done.
  • Authenticated - sender's email domain is fully authenticated, and it should give you a boost in email deliverability rates.
  • Not authenticated - sender's email domain still needs to be authenticated. You can read more about it in this article.
  • Canceled - sender verified their email address but then canceled the approval for using it for sending email campaigns.

Under the icon with three dots, you can resend verification emails, and edit or remove the sender. Removed senders, due to the registered log of their email activities, are being archived by Prowly, but do not display in the Senders addresses window.

You can add and verify senders that don't use Prowly with you. This function is especially useful for agencies executing multiple email campaigns for various clients. Every verified sender can be chosen in the Write step of email creation. 


The limit for unique senders is 5 times bigger than the number of users working on your account - but no bigger than 120. For example, if you have 10 users registered, you can authorize up to 50 sender addresses.

User roles

  • Admin & Owner - can view, add, authorize, edit, and remove senders
  • Publisher - can view, add, authorize, and edit senders, but cannot remove any
  • Viewer & Writer - can view senders, but cannot add, authorize, edit, or remove any

Why should I verify every sender?

Sender verification not only protects your email delivery rates but also prevents unwanted or non-existent senders from distributing emails. 

If you have provided a faulty email address by mistake, and it's not associated with any sender, they simply won't receive a verification email.
