Merge Fields
Merge fields let you personalize email content by inserting contact-specific or event-specific data into your subject lines and email bodies.
Syntax
Use double curly braces around the field name:
Hello {{first_name}}, your event starts soon!Whitespace inside the braces is flexible — {{first_name}}, {{ first_name }}, and {{ first_name }} all work identically.
Available Fields
| Merge Field | Resolves To | Typical Use |
|---|---|---|
{{first_name}} | Contact's first name | Greeting personalization |
{{last_name}} | Contact's last name | Full name display |
{{email}} | Contact's email address | Account reference |
{{event_title}} | The trigger event's name | Event reminder campaigns |
{{event_date}} | The trigger event's start time (formatted) | Event countdown emails |
{{event_location}} | The trigger event's location | Venue/direction info |
Event Fields
The event_* fields are only populated for date-based campaigns that have a trigger_event_id. For evergreen campaigns or broadcasts, these fields will resolve to an empty string.
The {{event_date}} field is automatically formatted in a human-friendly style:
Saturday, March 15, 2026 at 7:00 PM
Fallback Behavior
If a merge field cannot be resolved (e.g., the contact has no first_name), it is replaced with an empty string. This ensures recipients never see raw {{...}} syntax in their emails.
Any unrecognized merge fields (typos like {{fist_name}}) are also silently removed.
