⚠️ Important Notice

BuzzRelay automates WhatsApp Web. It is your responsibility to use this tool in compliance with WhatsApp’s Terms of Service. Only send messages to contacts who have consented to receive them. Mass-sending unsolicited messages is against WhatsApp’s policies and may result in your account being restricted. The built-in anti-ban features reduce risk but do not eliminate it. The developer is not responsible for any account restrictions arising from misuse.

Frequently Asked Questions

Q: Is this a one-time purchase or a subscription?
A: One-time purchase. No monthly fees, no usage charges. Buy once and use forever.

Q: Does it work on VPS / Windows Server?
A: Yes. BuzzRelay is specifically designed to run on Windows VPS environments. It ships with its own Chromium browser so it does not depend on system-installed browsers.

Q: How many contacts and devices can I add?
A: There is no hard limit in BuzzRelay. Add as many contacts, groups, devices, and campaigns as your machine can handle.

Q: Can I personalise messages per contact?
A: Yes. Use {name}, {phone}, {email}, {company}, and any custom fields you define. Each message is personalised individually before sending.

Q: Does it work with WhatsApp Business?
A: Yes — both standard WhatsApp and WhatsApp Business accounts are supported.

Q: Will my number get banned?
A: BuzzRelay includes several anti-ban tools (delays, typing simulation, daily limits, Number Warmer). These reduce risk significantly when used with opted-in contacts and reasonable volumes, but no automation tool can guarantee zero risk.

Q: Is the source code included?
A: No. Source code is not available for purchase.
