Claude · WhatsApp · Outreach
A few weeks ago I did something that surprised even me: I got Claude to send personalised WhatsApp messages on my behalf — using my own number, reading real replies, running follow-up sequences — all from inside Claude Code on my Mac. No third-party services, no monthly subscription, no code headaches (mostly).
This is the exact setup I use today for community outreach. Here's how to replicate it.
Who this is for: Anyone using Claude Code who wants to connect WhatsApp for personalised outreach, reminders, or follow-ups. No programming background needed — I'll show you exactly what to type.
Most AI tools send emails. Emails get ignored. WhatsApp messages get read — open rates are routinely above 90% for business contacts in Singapore and Southeast Asia. Combining Claude's writing quality with WhatsApp's reach is genuinely powerful.
The integration works through Claude's MCP (Model Context Protocol) — a standardised way for Claude to talk to external tools. Once wired up, you can say things like "Send a follow-up to everyone who attended the April event but hasn't registered for May" and Claude handles the drafting, personalisation, and sending.
Open your terminal and run:
This installs the MCP server that bridges Claude and WhatsApp Web.
In Claude Code, open Settings → MCP Servers → Add Server. Paste this config:
The first time you start the MCP server, a QR code will appear in your terminal. Open WhatsApp on your phone → Settings → Linked Devices → Link a Device, then scan the QR code. Done. Your session persists so you only do this once.
Back in Claude Code, try a simple prompt:
"Using WhatsApp, send a message to [your own number] saying 'test from Claude'"
If it works, you'll receive it on your phone within seconds. If Claude asks for confirmation before sending — that's the safety check working correctly.
Now the fun part. Here's a real prompt I use for event follow-ups:
"Here's a list of people who attended last week's workshop [paste list]. Send each of them a personalised WhatsApp message thanking them by name, referencing the specific topic they said was most useful, and inviting them to next month's session on [topic]. Keep it warm and under 3 sentences."
Claude drafts each message, shows them to you for review, then sends on confirmation. The personalisation quality is noticeably better than any template tool I've used.
In the Cowork SG community I use this for: event reminders (sent 24h before, with location), post-event thank-yous with a personalised note, and reaching out to people who expressed interest in a resource but haven't downloaded it yet.
The biggest unlock? Combining it with Claude's memory. I keep a running note of each contact's interests and last conversation. When Claude drafts a follow-up, it actually references something specific — which gets replies.
We run hands-on sessions where community members set this up together. Join free on WhatsApp and get the next session date.
