You can instantly welcome all new members in your Mighty Network by navigating to Host Management > Members and tapping on the link that says "Welcome new members."
Every time you tap on the button, you'll automatically send a welcome note to every new member who's joined since the last time you welcomed all new members. It's the quickest and fastest way to make every new member feel like they are a valuable part of your community.
After you tap on the link to welcome all new members, those members will receive a quick note either via email or push notification, depending on their notification preferences.
Here's a preview of what a welcome email look like when it lands in someone's inbox:
If you want to give your new members even more opportunities to learn what your community is all about, you can also add a Welcome section for them to see at the top of the feed right after they join.
