Group Outreach
No customer list?
Your buyers are already gathered in WhatsApp groups
Type an industry keyword and Casii auto-finds public industry group invite links; multiple accounts join together, and member phone numbers land in your library in one click — a reachable customer list, no adding friends one by one.
Auto-find groups, lock on in bulk
You don’t need to know where the groups are — type an industry keyword like “dental care” and Casii auto-collects public group invite links page by page, listing target groups for you to tick.
Distribute group joins across multiple accounts
Selected groups are spread across multiple accounts, and each group is joined by one account. Joins run one at a time with a random interval between them; after repeated errors, that account’s joins pause for a while and then resume automatically.
Members into your library in one click
Joining is just the start — import the members of the groups you’ve joined into your lead library in one click, deduplicated automatically by phone number and ready for outreach.
