You can accept donations with PayPal. To do so, add your PayPal account email in your Donorbox account settings

However, we highly recommend using Stripe as it provides a faster checkout process for donors who don't have a PayPal account. With PayPal, the donor will be redirected to Stripe allows the donor to enter his or her card number directly in your donation form. It's most optimal to use both Stripe and PayPal.
