Import contacts from CSV

Contacts enter SendCanyon through CSV import (or the API). Every import runs through the same three-stage pipeline: upload, column mapping, and validation. Nothing gets emailed until it survives all three.

1. Upload

Go to Contacts → Import CSV and drop your file. UTF-8 CSVs up to 50 MB are accepted; the first row should be headers. You can import into an existing list or create a new one during the import — lists are how campaigns select their audience, and a contact can belong to several.

2. Column mapping

SendCanyon previews the first rows and auto-matches headers to fields — email, first_name, last_name, company, title, phone, website, timezone, plus any custom fields you've defined. Check the auto-matches, map anything it missed, and pick Skip for columns you don't want stored. Only email is required. Unmapped data is not imported; we deliberately don't hoard columns you didn't ask for.

3. Verification

Verification starts automatically when the import finishes, and contacts you add one at a time or through the API are verified the same way. The checks that run are listed under Email Verification. Rows also dedupe against contacts already in the workspace and screen against your suppression list. Each contact ends up in one of three verdicts:

Every verdict carries its reason, shown next to the contact and in the import's results, which you can download as a CSV from Deliverability → Email Verification. Held contacts stay out of campaigns unless you opt them in on the campaign's Audience tab. Contacts on your suppression list are never emailed, and duplicates are merged.
