What is the Birthday Field? #
The Birthday field is a standard system field that captures a contact’s birth date (Month/Day/Year).
It can be populated through:
- Manual entry
- Form submissions
- CSV Imports
- API integrations
This field enables automation triggers based on birthdays and helps segment contacts by age.
How to Build Birthday Reminder Campaigns #
You can automate birthday reminders or offers by setting up birthday workflows.
Step 1: Configure the Birthday Trigger #
- Navigate to Workflows > Create New Workflow.
- Set the Trigger to Birthday.
- Choose the trigger condition:
- On the birthday
- Before the birthday (e.g., 7 days before)
- After the birthday (e.g., 1 day later)
- On the birthday

Step 2: Define Actions #
#
- Send Email: Personalized birthday greetings or offers.
- Send SMS: Short birthday wishes or coupon codes.
- Assign Task: Alert internal teams to follow up manually if needed.

Example Workflow Structure #
Step | Action |
---|---|
1 | Trigger on Birthday |
2 | Send Birthday SMS |
3 | Send Birthday Email |
4 | (Optional) Notify the internal team |
How to Filter Contacts by Age in Smart Lists #
Using the Birthday field, you can segment your contacts based on their age for targeted communication.
Steps to Filter by Age #
- Go to Contacts > Smart Lists.
- Apply a Filter using the Birthday field’s Age condition.
- Select the appropriate comparison:
Filter Condition | Use Case Example |
---|---|
Age is greater than X | Target seniors aged 50+ |
Age is less than X | Promotions for young audiences under 25 |
Age is between X and Y | Target specific age groups, e.g., 30–40 years |

The system calculates age dynamically based on the current date and the stored birthday.
Best Practices #
- Capture Birthdays Early: Include a Birthday field in lead capture forms to gather the information upfront.
- Validate Date Formats: Use MM/DD/YYYY format to ensure automation triggers work correctly.
- Test Automation: Always test birthday workflows with sample contacts before making them live.
- Consider Time Zones: Be aware that workflows may use contact-specific time zones if configured.
Common Issues and Troubleshooting #
Issue | Solution |
---|---|
Birthday automation is not triggering | Ensure the Birthday field is populated with a complete and correctly formatted date. |
Incorrect age calculation | Confirm that the birth year is correctly entered. Missing or incorrect years can cause errors. |
SMS or email was not sent on the birthday | Double-check workflow timing, trigger configuration, and contact timezone settings. |
