Contacts & lists
Build your audience — add contacts by hand, by CSV or from your inbox, and group them into lists for campaigns.
Campaigns are sent to lists of contacts. Contacts belong to the WhatsApp number that’s currently selected.
Phone numbers
Always include the country code. +971 50 123 4567, 971501234567 and 00971501234567 all work, and spaces and dashes are fine. A number without a country code, such as 050 123 4567, is rejected — WhatsApp needs the full international number.
Add contacts
Open Contacts from Bulk Messaging → View Customer.
- Add Manually — enter a name and number, optionally choose lists, and click Save Contact.
- Upload CSV — choose a CSV file with
NameandNumbercolumns (up to 5 MB). Check the preview of the first rows, optionally choose lists, and click Confirm Upload. Rows with numbers that can’t be used are skipped and reported, so you can fix them. - Fetch Contacts — adds everyone who has messaged this WhatsApp number. Numbers that are already contacts are skipped.

Lists
A list is a named group of contacts that you use as a campaign’s audience.
- Open Lists from Bulk Messaging → View List and click + Create List.
- Enter a list name — names must be unique.
- Select existing contacts, or upload a CSV of contacts to add, and create the list.
Open a list to view its contacts, edit it or delete it. You can also create a list from the first step of a new campaign, or add Lead Finder results straight to a list.
