WA Local Engine runs on your Mac or Windows PC and sends messages through your existing WhatsApp Desktop app — the same one you already use. No Business API approval. No per-message charges. No SaaS subscription eating into your margins.

You load your prospects, write your message templates, press Start — and the scheduler handles everything from there.

Sales reps sending cold outreach and follow-ups to leads

School and college admissions teams contacting prospective students

Real estate agents nurturing property enquiries

Coaches and consultants following up with prospects

Small agencies running WhatsApp outreach for clients

If you're currently copying and pasting WhatsApp messages manually, this replaces that entirely.

Message sequences Write a series of 2–5 messages. Each prospect receives them automatically, 2 days apart, with a random ±1 hour variation to keep timing natural.

Template variables Every message is personalised. Use {recipientName}, {prospectsName}, {prospectCity}, {prospectCountry}, {salesPersonName} — and more — in your templates.

Media attachments Attach images, videos, PDFs, or documents to any message using simple [media:path] syntax.

Rate limiting built in 50 messages per hour, with a 20–45 second random delay between each send. Designed to stay under the radar.

Invalid number detection Automatically skips numbers not registered on WhatsApp. No failed sends, no noise in your logs.

Dry run mode Preview every message that would be sent — without actually sending anything. Verify your templates look right before going live.

Sleep prevention Keeps your machine awake automatically while the scheduler is running. No babysitting required.

Will my WhatsApp account get banned? WA Local Engine is built with conservative rate limits — 50 messages per hour, with randomised delays between each send — to mimic natural human behaviour. That said, any bulk outreach carries inherent risk. Use it for targeted, relevant outreach to contacts who would reasonably expect to hear from you. The tool is designed to protect your account; spamming with it defeats that purpose.

Do I need to keep my computer on? Yes. The app sends through your local WhatsApp Desktop, so your machine needs to be running and WhatsApp needs to be open. Sleep prevention is built in — the app keeps your display awake automatically during active sessions.

What happens after I pay? Your license tier activates automatically within minutes of payment. Reopen the app and it syncs — the tier badge in the header updates from FREE to your plan. No waiting, no manual steps.

Can I move the license to a new machine? Yes. All paid plans include 2 machine transfers per 12 months, built into the app. No support ticket needed.

Is there a refund policy? Try it free before you buy — the free tier activates automatically with no card required. If you upgrade and change your mind within 7 days, we'll refund you in full.

WA Local Engine sends messages through your personal WhatsApp account. Use it for genuine, targeted outreach — not mass spam campaigns. WhatsApp's Terms of Service prohibit automated bulk messaging, and misuse risks account suspension. The rate limits in this tool are there to protect you.
