Contacts and channels

Bringing in the contacts you already have

Start from the list you already have, without typing anyone in.

Updated on 13/08/2026

Nobody starts from zero: the supplier or client list already exists somewhere, even if only in a spreadsheet. Bringing it in whole takes half an hour and avoids the slowest possible start, which is typing two hundred contacts.

What the list needs

Half an hour well spent before importing

  1. 1

    Remove duplicates: the same person twice becomes two records with split histories.

  2. 2

    Remove people who have left: dead addresses gain you nothing.

  3. 3

    Check the columns: an email in the phone column is spotted by your eye before the system's.

Watch out

Importing a dirty list does not clean it: it relocates it. From then on the bounces show up inside cases, when they get in the way.

Worth knowing

If you have ten years of contacts, bring only the active ones. The rest can be imported later if needed, and meanwhile they do not clutter searches.

Important

That list holds personal data about people who did not choose to be in your new tool. Bring what you need to work — name, email, professional contact number — and do not drag along fields you will never use just because they were in the file.

Can I re-import to update?

Yes, and existing records are updated rather than duplicated.

What if my system does not export to a spreadsheet?

Almost all do. Failing that, it can come in through the API.

Are contacts notified when imported?

No. Importing sends nothing; notices go out when you launch something.
