Prepare your contact data
Fill in the CSV with your contact records. The only required field is a valid phone number in E.164 format (e.g.
+14155552671). Optional fields include first name, last name, email, tags, and any custom fields.4
Upload and map columns
Upload the completed CSV and use the column mapping interface to match each column in your file to the corresponding contact field in WaMatrix.

Choose handling for duplicates
Decide what to do when an uploaded contact’s phone number already exists: Skip (keep the existing record unchanged) or Update (overwrite the existing record with the new data).

+ prefix. Multiple tags are comma-separated and wrapped in quotes.
Custom Fields
Admins can create custom contact fields to store business-specific data that isn’t covered by the standard fields. Supported field types include:
Custom fields are available as template variables (e.g. populate
{{1}} with a customer’s tier) and as segmentation criteria (e.g. target all contacts where tier = “Gold”).
Opt-In Status
Every contact in WaMatrix has an opt-in status — this is the single most important compliance field in the platform:
Contacts can be opted in via:
- A web form connected to WaMatrix
- An automation flow that sets opt-in status based on a trigger event
- Manual update by an admin on the contact record
Segments
Segments let clients define a filtered sub-set of their contacts for use in campaigns, automations, and reporting. To create a segment:- Go to Contacts → Segments → New Segment.
- Define one or more filter conditions — e.g. tag =
"vip"AND last message date > 30 days ago. - Save the segment. The contact count updates automatically as contacts match or stop matching the criteria.
