Event RSVP form for Slack
Get a Slack message for every RSVP — watch the guest list fill up in real time.
For team events and launches, RSVPs are more fun when everyone sees them. This form posts each one to your channel with attendance and guest count attached.
It doubles as a nudge — a visible, growing list reminds the stragglers to reply. Catering details still land in the data; the buzz lands in Slack.

- 3
Collect on autopilot
Every submission posts a message to your Slack channel in real time, with your form fields mapped to the right message lines.
How your fields map to Slack
Each form field becomes a message line. Edit the mapping anytime in the form editor.
| Form field | Slack message line |
|---|---|
| Your name | Your name |
| Will you attend? | Will you attend? |
| How many guests (including you)? | How many guests? |
| Any dietary notes? | Any dietary notes? |
The honest catch
The honest catch: Slack rate-limits to about one message a second per channel, so a viral spike queues rather than floods. For most forms you'll never notice.
Questions
Is the event rsvp → Slack integration free?
Yes. The form and the Slack connector are included free with unlimited submissions. You only pay for usage-based add-ons, never per-response.
Do I need to write any code?
No. Connect Slack, map your fields in the visual editor, and you're live. The webhook plumbing is handled for you.
Can I customize the event rsvp form?
Completely. Add or remove fields, change labels, add conditional logic — the Slack mapping updates alongside it.
Every submission posts a formatted message to your Slack channel.
Free forever. Unlimited submissions. No credit card.
