WhatsApp APIEmail SMTPREST API

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

  • Send one-by-one from personal WhatsApp
  • Contacts scattered across Excel files
  • No pacing — easy to hit limits or get blocked
  • Email and WhatsApp in separate tools
  • No API for your app or CRM

With Menjalin

One messaging hub

  • Paced broadcasts to tagged audiences
  • Contacts, tags, CSV import in one place
  • Smart pacing, schedules & send windows
  • WhatsApp + email from the same dashboard
  • Production REST API for developers

From signup to send in four steps

Connect → Contacts → Broadcast → Track
