Send bulk WhatsApp and email messages with status tracked in Sheets

Sends WhatsApp messages and emails to your contact list in batches and tracks delivery status in Google Sheets.

How the work actually flows

It repeats. Every path runs; all paths must finish before it continues; repeats process next batch; runs once per one per contact in batch.

Pattern: Structured Loop (21) · Parallel Split (2) · Synchronisation (3) · Multiple Instances with a priori Run-Time Knowledge (14)

The problem it solves

Sending the same message to a long contact list by hand is slow, and it's easy to lose track of who you've already reached or who failed to receive it. Without a record, you risk messaging people twice or missing contacts entirely.

Who it fits

A business running bulk outreach campaigns over WhatsApp and email who needs reliable delivery tracking.

How it works

  1. You start the send with your contact list stored in Google Sheets
  2. Contacts are processed in small batches to stay within messaging limits
  3. The system sends emails through Gmail and messages through WhatsApp to anyone still marked pending
  4. Every success or failure is written back to Google Sheets
What you get

Messages delivered across WhatsApp and email

You get your WhatsApp and email campaign sent out in batches, with delivery status tracked automatically.

What you get

An updated Google Sheet showing exactly who received each message, with failures flagged for retry.

What you need

A Google Sheets account, a Gmail account, a Google Drive account, and a WhatsApp Business account.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
