Email Autoresponder in Popupsmart
Learn how to set up and customize the Email Autoresponder in Popupsmart to automatically send follow-up emails to your popup subscribers.
The Email Autoresponder feature in Popupsmart allows you to automatically send a follow-up email to visitors who subscribe through your popup. This is commonly used for welcome emails, discount delivery, confirmation messages, or onboarding sequences.
Autoresponder emails are sent automatically -- immediately or with a delay -- and without requiring an external email marketing tool.
