You can absolutely do this using Omnisend’s Anniversary filters, which are designed specifically for birthdays and other recurring customer milestones.
To create a segment for contacts with upcoming birthdays:
Go to Audience → Segments → Create segment.
Add the Birthdate filter.
Choose “Anniversary is in the next” and specify the number of days you’d like to target.
For example:
Today:Birthdate → Anniversary is in the next → 1 day
Tomorrow:Birthdate → Anniversary is in the next → 2 days
Next 7 days:Birthdate → Anniversary is in the next → 7 days
The segment updates dynamically each day, so contacts automatically enter and leave the segment as their birthday approaches.
Note: If you’re importing birthday data rather than collecting it through Omnisend forms, make sure the dates use the YYYY-MM-DD format.
Once your segment is ready, you can create a segment-based automation and trigger it whenever a contact enters (or exits) that segment.
This gives you a fully automated way to send birthday campaigns at exactly the right time. If you need a hand setting it up or tailoring it to your birthday campaign strategy, we’re always happy to help.
