I have been using Ninja Forms for some time now and really liked the flexibility and ease with which developers can create their own extensions. I already have a wordpress plugin for integrating Sendy which is available for download from codecanynon. For those who want to subscribe users using Ninja Forms I have created a new extension Sendy for Ninja Forms.
List of features
- Unlimited Form subscriptions
- Different List ID’s for different Forms
- Subscribe user with Email , First & Last Name.
You can download plugin from here.
