Integrations
Delivery into the tools your staff already use.
Promo Engine is where the work is decided and assigned. When a piece is assigned, Promo Engine posts to the chat tool the church connects and sends an email, and each person's pieces appear in the calendar they subscribe to. No one is asked to use a new inbox.
Where Promo Engine posts
Where it posts
One chat tool per church. In Slack each person gets a direct message. Everyone gets an email in every case, so a church that connects nothing is still notified.
Slack
The biggest single answer when we asked, and the one churches most often leave. Free plans keep 90 days. Added once with a button, and then each person on the team gets their own message rather than a channel post.
Google Chat
Free with Google for Nonprofits, and where most of the churches leaving Slack said they went.
Microsoft Teams
For churches already on Microsoft 365. Promo Engine uses the Workflows webhook, since Microsoft retired the old connectors in May 2026.
Anything else
One address covers Trello, Notion, Basecamp, BAND, NiftyPM, or Zapier in front of whatever you run. If it takes an incoming webhook, Promo Engine can post to it.
Promo Engine writes messages and reads none. It sends nothing to a member of the church. It writes into no other system, and reads only the calendar below.
The calendar
The calendar feed
Each person subscribes once to a feed of their own pieces. It updates itself and needs no account linking: it is a read-only feed, not a write into the calendar.
With the rest of Engine
Two more, later
Adding a guest to the Mailchimp or Clearstream list a church already runs comes with People, and reading the giving and spending file a church already exports comes with Operations. Both are in development on the same account, and a Promo Engine account becomes an Engine account when they open.
Alongside
What a church runs
Promo Engine does not replace a church management system, a giving platform or a website. Recording what the church runs stops setup from asking about it twice.
Church system
Giving and accounting
Team messaging
Boards and docs
Email and texting
Everything else
A system not on the list works if it accepts an incoming webhook. The list is extended as churches report what they run.

A connection is a pasted address during setup, about a minute each.
