The importer also recognizes common phone header aliases such as phone, phone_number, and phoneNumber. There is no separate mapping step, so keep headers close to the supported names before uploading.
Before You Upload
Clean the CSV first so the import goes smoothly:- keep one contact per row
- make sure phone numbers are in a consistent international format
- remove columns you do not need
- use simple, stable tag values
- check that the header row is present
Import Flow
Import History
Import history tracks each job with status and progress:- Pending
- In Progress
- Completed
- Failed
Notes
- Very large files are surfaced during preview so you can split before importing.
- The platform matches existing contacts by phone number, updates name and email fields when present, and applies tags from the import.
What To Do After Import
After the job completes:- Open Contacts and spot-check a few records
- Verify tags and phone numbers look correct
- Add the imported contacts to a campaign if needed
- Download the error CSV if some rows failed validation
