Yes, Your PayPal e-mail address and the address that you use on the Honeygain app can be different. Once you request the payout, you will receive an email from our payout processor "Tipalti" with an invitation link to sign up for an account using your payout details. You will be able to enter any PayPal email that you want!
If along the way you wish to change the PayPal email address that you use for the payouts, you would need to sign in to your Tipalti account by following this link and proceed with the changes there.
