This plugin extends Easy Digital Downloads by allowing to send custom purchase receipts for license renewals and license upgrades. You no longer have to use the standard purchase receipt for all purchases.
AffiliateWP ConvertKit allows you to add affiliates to your ConvertKit email marketing list upon their registration. A variety of settings gives you even more options to customize the subscription behaviour.
Integrate your Easy Digital Downloads store with Sendy by subscribing your customers to specific lists based on what they purchased, and allowing customers to opt themselves into a list during checkout.
