  1. Open Messages in the sidebar.
  2. Click the round + button and pick the channel: Send to Feed, Send to SMS or Send to Email. See The Messages hub if you are unsure which.
  3. Set the Audience: Everyone, Selected people, or a Custom Filter — use a custom filter to send to a group.
  4. Write the message. For email you can Design manually or Design with AI.
  5. Read the Summary card, then press Send message (or Schedule message if you chose to schedule it).

Who actually receives it

Selecting people is not the same as reaching them. A message only lands where the person can receive it:

  • A feed message reaches members who have the app installed and are signed in.
  • An SMS reaches people with a valid mobile number who have not opted out.
  • An email reaches people with a valid address who have not unsubscribed.

People missing a detail, or who have opted out, are skipped. That is why the recipient count can be lower than the number of people you picked — it is working correctly.

Sending it later

A message can be scheduled instead of sent now, which is how most churches handle Sunday reminders — written on Thursday, delivered Saturday evening.

Before a large send

  • Send it to yourself first. It is the only reliable way to see what it actually looks like.
  • Check every link.
  • Say who it is from in the message itself — people should not have to work out which church texted them.
  • For SMS, keep it short and put the important part first.
