How Artra avoids double contacts and double sends, and the switches that control it.
Imports match on email: an existing contact is updated, not duplicated.
Org settings → "Duplicate-contact policy": block, warn or allow when a teammate already has the email.
Keep this on so one person is never in two sequences at once.
In Contacts → Actions:
"Verify emails" marks bad addresses so they are skipped.
"Do not contact" stops all outreach without deleting history.
On Research, "Enrich Data" → "Data Enrichment" cleans and validates fields in bulk.
Click "Data Enrichment".
Run verification across a whole list before enrolling it.
Import contacts from a CSV
Upload a spreadsheet of people, map the columns and optionally drop them straight into a sequence.
Add one contact by hand
Create a single contact without a spreadsheet.
Add contacts to a sequence
Select people in the Contacts table and enroll them in a sequence in one go.
Search, sort and choose columns
Find people fast and show only the columns you care about.
Work a contact from their profile
Everything about one person: activity, sequences, calls, tasks, and quick actions.
Verify email addresses
Check which addresses are safe to send to before they go into a sequence. Only invalid ones are skipped when sending.
