There may be a few reasons some users look like they should be receiving a message, but aren’t:
- If the user received another campaign message, Intercom might be waiting the spacing period you’ve set on the campaign before trying to send the next message.
- Users must log in to your app to receive in-app messages. If the user doesn’t log in in the spacing time allotted in your campaign, Intercom will look for a different message to send.
- If the message is an email, there might be a delivery window on the message. In this case we’ll wait for the window to open for that user before sending the message.
Important: Users must also meet the rules for individual messages in a campaign to receive them.
