Triggers

These communications are sent on the basis of the trigger you select.

📖 Further reading: Form and Event Communications Triggers & Groups

There are three main types of triggers:

Upon

These triggers depend upon a given action, like a registration for the event, or the event being cancelled, among others.

📖 Further reading: See the following articles related to certain Upon triggers:

• Upon registration (including related event registration): Mailing is delivered to recipient when they register for this or any related events.

• Upon waitlist registration: Mailing is delivered to recipient when they register for the event’s waitlist.

• Upon decline: Mailing is delivered when a recipient declines an RSVP.

Time

The mailing is delivered some amount of time before or after the event.

In the offset fields, enter days, hours, and minutes to specify how far in advance or following the event or deadline that the mailing should be sent.

Outreach mailing (send as scheduled)

The trigger for outreach mailings is the date and time at which you’ve scheduled it to send. In this way, they’re like traditional Deliver mailings. This type of trigger is ideal for RSVP emails.

Groups

In the context of event communications, a group is the subset of records in the recipient list that qualify to receive the communication.

Calendaring

When you create a new event communication, you can select one of two calendaring options:

Attach iCal File

This option attaches a .ics calendar invite file to the communication.

The recipient must download and open the file in their calendaring app of choice. They may need to manually import the file.

Attach Meeting Invite

🏔️ Summit 2025 Feature

This option attaches a meeting invite to the communication. These invites are picked up automatically by modern calendaring services, like Google, Microsoft 365, the Apple Mail app, and more.  

When someone receives an email with a meeting invite, their calendar client pencils in the Slate event at the date and time it’s scheduled to occur. Keep in mind that this behavior may be impacted by the recipient’s preferences in their calendar app.
