How to Blast a WhatsApp Message (Step by Step)
A simple step-by-step for sending a WhatsApp blast to your own contacts at once — your customers and leads, without saving each number in your phone or getting your line banned.
The short version
To blast a WhatsApp message you need a tool that connects your number and sends to a contact list with safe pacing. The native app caps you at 256-contact broadcast lists and only reaches people who saved your number. Here is how to do a real blast with App365.
Step 1 — Connect your WhatsApp number
Sign in and scan a QR code to link your number. You can connect more than one number depending on your plan.
Step 2 — Import your contacts
Upload your own contacts — customers and leads who expect to hear from you — from Excel or CSV, or paste numbers (with country code). Group and filter them so the blast only goes to the right audience. This is for your own list, not for cold-messaging strangers. You do not need to save each number in your phone.
Step 3 — Write or load a template
Type your message or load a saved template, and add variables like {name} so each message is personalised. You can attach an image for promos.
Step 4 — Set safe-sending options
- Random min/max delays between messages
- Per-device batch size and rest intervals
- A daily sending limit per number
- Exclude blacklisted / opt-out numbers
Step 5 — Send now or schedule
Send immediately, or schedule the blast for a specific date and time. Then track sent, failed and success counts, and resend to anyone who failed.
FAQ
How do I blast WhatsApp to my contacts without saving each number?
Import your own contacts (customers and leads who expect to hear from you) into App365 from Excel/CSV or paste them, then send — you do not need to save each one in your phone first. App365 is for your own list, not for messaging strangers or scraped numbers.
How many messages can I blast?
There is no hard cap in the software; safe throughput depends on how many numbers you connect and your warmup level. Pace it and warm up new numbers first.
Will I get banned for blasting?
Aggressive sending causes bans. Use warmup, rate-limiting and relevant messages to opted-in people to greatly lower the risk.
