Importing contacts

Bringing a CSV in from another platform, and what happens to duplicates.

Import brings a CSV of existing contacts into a brand. It is the usual way to move from another platform.

Before you start

  • Export a CSV from your current platform. Most export contacts plus subscription status.
  • Make sure the first row is column headers.
  • Remove anyone who has unsubscribed, unless your export marks them so you can map that status.
Only import people who agreed to hear from you

Importing a purchased, scraped or rented list breaches the Nectazo terms and will get your sending suspended. It also damages your domain reputation in ways that take months to recover from. See Consent and unsubscribes.

Running an import

  1. 1Go to Contacts → Import and choose your CSV.
  2. 2Map each column to a Nectazo field. Anything you map to a name Nectazo does not recognise becomes a custom field.
  3. 3Choose a list to add everyone to. This is optional but almost always what you want.
  4. 4Review the preview, then import.

Imports run in batches and show progress. Large files take a little time; leave the tab open.

What happens to duplicates

Matching is on email address within the brand. An address already present is updated, not duplicated — the fields in your CSV overwrite what was there. An address that is new is created.

What is never overwritten

Unsubscribes survive imports

If someone previously unsubscribed or complained in this brand, importing them again does not resubscribe them. Suppression wins. This is deliberate and cannot be turned off — re-mailing someone who opted out is both illegal in most jurisdictions and the fastest way to get a spam complaint.

Plan limits

Nectazo checks the whole file against your contact limit before importing anything, so you never end up with a half-finished import. If the file would put you over, it tells you which plan covers it.
