Contacts
Contacts are keyed by phone number: one contact per number per account, and imports upsert rather than duplicate.
Fields
name,phone(E.164),notestags: free-form labels that double as broadcast audiencesfields: up to 20 custom key/values, usable in merge fields as{{field:key}}
CSV import
Console → Contacts → Import CSV. The first row must be a header including a
phone column (phone, number, mobile…). Unrecognized columns become
custom fields. Existing contacts are enriched, never wiped: a row with only
name+phone will not erase tags you added by hand.
Export
Console → Contacts → Export downloads the whole book as CSV, custom fields as columns.
Names in the inbox
Inbound messages resolve the sender against contacts, so threads show "Jane Doe" instead of a raw number the moment a contact exists.
