Why this helps
Event outreach can become scattered across campaign planning, contact selection, and manual mail preparation.
- Give selected contacts a physical event invitation.
- Use a prepared invitation PDF and confirmed addresses.
- Start the workflow from an HTTP request in your campaign process.

- 2Create an automation and describe which selected contacts should receive an invitation.
- 3Choose a webhook trigger and have your process send an HTTP request for the selected invitations.
- 4Choose where run reports should go.
- 5Test with one real contact and verify sender, recipient, and invitation PDF.
Questions about this workflow
Does this workflow choose contacts from an ActiveCampaign event?
No ActiveCampaign trigger events are listed. Your campaign process must send the webhook for selected contacts.
What document is mailed?
A PDF URL supplied by your team. Review the invitation and recipient details before sending.
Can it mail an entire contact list?
The send action supports a specified recipient. Use a test first and confirm each intended recipient through your process.
