The Subscription Plus addon expands the Popup Builder subscription popup by adding custom fields (phone, text, number, checkbox), automatic notification to the administrator for each new registration, and an autoresponder for sending offers and promotions to subscribers.

Designed as a boost to Popup Builder’s capture form, the Subscription Plus addon turns a simple opt-in into an entry point for basic email automation: every visitor who subscribes starts feeding a routine of welcome emails, offers, and internal alerts without requiring an external platform.
