Description
Send personalized WA campaigns. No API. No monthly bill.
WA Local Engine runs on your Mac or Windows PC and sends messages through your existing WA 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.
Who this is for
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.
What it does
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.
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.

Frequently asked questions
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.
Fair use notice
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.
