Ad Booking Software for Newsletters?

Hey Awesome Creators!!

Which ad booking software do you use on your newsletter for auto ad bookings/sponsorships without having to have back and forth communications with the sponsors?
I have seen a few use Calendly while others use Jotform. Calendly isn't an option for me as it supports Paypal or Stripe, which unfortunately I don't have.
Is there any ad booking software that supports Wise .com or Payoneer?
