You can add the emails to your email autoresponder service manually.
This screening process allows you to select those that match the ethos of your group.
Whilst this may be easy when your group is small it becomes labour intensive as your membership grows.
Group Convert helps you get around this problem.
It is a chrome extension launched by Kim Dang. Once installed, whenever you approve a member to your group, it automatically saves their info (username, first name, last name) plus their answers to your Group’s screening questions.
This saved information can be pushed onto a Google sheet and then connected to your email service through Zapier.
So each time a member is added to your Google sheet, Zapier will automatically add them to your email list
Simple but very clever!.
