WhatsApp & email broadcasts · one dashboard
Send WhatsApp & email broadcasts the easy way — from one dashboard.
Schedule promos, notifications, and follow-ups to thousands of contacts automatically—with audience segmentation, smart pacing, and a REST API that plugs straight into your product.
- Go live in minutes: sign up, connect a channel, import contacts, then send.
For SMBs, agencies, and developer teams in Indonesia
One ops layer instead of five tools
Most teams stitch together spreadsheets, personal WhatsApp, and a separate email sender. Menjalin replaces that patchwork.
“Finally one place for broadcasts and API — our team stopped copying numbers by hand.”
Manual process
Spreadsheets & phone
