There is an affiliate platform called Referly that integrates with Pickaxe. I have been using it for maybe a year and it’s one of the best affiliate platforms I’ve used. I bought it from ■■■■■■■, the founder made it by request for a pickaxe user.
It is currently back on ■■■■■■■ for 7 days only. Sharing the link here in case anyone wants to check it out: Referly - Create your own referral program | ■■■■■■■
