Hi @Nikki148 ,
Thank you for posting to the PayPal Sandbox Community.
There are two different ways to resolve this issue. You can reply to this post and provide the sandbox merchant id, and if we can locate the sandbox account we can manually confirm the email.
The other option is to create a sandbox account from your developer dashboard, providing the email you want to use, and the email should automatically confirm itself.
Here are the steps for creating a new sandbox account:
Log into the Developer Dashboard at https://developer.paypal.com
Hover over Testing Tools
Click on sandbox accounts
Click Create Account
Click Create next to "Do you want a more customized account" (toward the bottom)
Choose Business
Choose your Country
Input the email address you want to use
Leave everything else as the default settings
Click Create Account
Input the password
(Leave first and last name blank)
Add an amount for the PayPal Balance (You can add 50,000 if you want its virtual money)
Click Create Account
I tested in the Developer Dashboard, and if you create the account through the dashboard the email will be auto confirmed.
Thank you,
Jennifer
