Answers for Wassuply, the Windows app for warming up WhatsApp numbers and running cold outreach: setup, warm-up, campaigns, licences and troubleshooting.
Create a free account on the sign-up page, confirm your email, then download the Windows installer from the Get started tab in your customer portal (more on the download page). Run the installer and the app opens when it finishes. Sign in with the same email; if you have a licence, your plan activates automatically, no licence key needed. The app and account are free; warming and sending need an active licence.
Wassuply uses email sign-in, not licence keys. Open the app and sign in with the email your licence is linked to, and your plan activates automatically within a minute. Have a gift or activation code? Enter it on the "No active plan" screen. Contact support if it has been more than 10 minutes.
Open Wassuply and click "Add Account" in the sidebar. A QR code will appear. Open WhatsApp on your phone, go to Settings, then "Linked Devices," and scan the QR code. The account will connect in seconds.
Wassuply requires Windows 10 version 1903 or later, or Windows 11. 64-bit operating system is required. Minimum 4GB RAM recommended for running multiple accounts simultaneously.
Every new number needs at least 15 days of warm-up before its first campaign, and 30 days is recommended. Health & Risk reads each number's age and history, counts its warm-up days, shows how many are left to the 15-day minimum and tells you when it is ready. Day-by-day detail: a new WhatsApp number's first 30 days.
Not on a new number before day 15. Under 15 days of warm-up a number's ban-risk score stays above 60, so Smart Send (when switched on) slows anything it sends, and Health & Risk will not mark it ready. Wait until it does, ideally around 30 days. Sending bulk too early defeats the purpose and raises the risk of a ban. Warm-up itself runs on autopilot in the background.
Your numbers chat with each other, and with Warm-up Pod partners from other Wassuply users, on autopilot. They use natural chat lines the same sender never repeats, with random 30 to 120 second gaps, and only inside the hours you set. Volume does not ramp up on its own: Health & Risk gives each number a plan (days to warm, safe daily limit, first campaign size), so start small and stay under the daily limit it sets. More in what WhatsApp warm-up is.
Bans after warmup are typically caused by: sending to numbers that have marked your messages as spam, using very similar message content to many contacts without personalisation, or exceeding recommended daily send limits too quickly. Enable message personalisation and keep the smart delay settings on to reduce risk. If the number is banned, the in-app WA Ban Appeal has 50 ready-made appeal scripts, and our free ban appeal letter tool works in the browser.
Contacts can be imported from a CSV file with phone numbers in international format (e.g., +447911123456). Go to Contacts, click Import, and select your CSV. The file should have one number per row or a column labelled "phone." Name and other fields are optional for personalisation.
Use tokens in your message template: {name} inserts the contact's first name, {phone} inserts their number, and {custom1} and {custom2} insert two custom columns from your CSV. Example: "Hi {name}, we have a special offer for you today." Add spintax and no two messages are identical.
Smart delay adds a random pause between messages, so they never go out on a fixed rhythm. By default Wassuply waits a random 30 to 90 seconds between messages, sends in batches of 10 and rests 1 to 5 minutes between batches. Keep the defaults or go slower. Higher delays mean slower campaigns but healthier accounts.
Click the account in the sidebar and select "Reconnect." A new QR code will appear. Scan it with your phone. Disconnections are normal and usually happen when your phone loses internet or goes offline for an extended period. The session is not banned, just expired.
There is no software limit on accounts. The practical limit depends on your PC's RAM and CPU. Most mid-range Windows PCs handle 10 to 20 simultaneous accounts comfortably. For 50-plus accounts, 16GB RAM is recommended.
Sign in with the same email you used to purchase. If you forgot your password, use "Forgot password" on the sign-in screen to reset it. Still stuck? Email support@wassuply.com from your purchase email and we will help.
A licence covers a set number of devices. To move to a new PC, deauthorise the old one from My Account in the app or from your customer portal, then sign in on the new PC. The optional encrypted backup restores your logged-in numbers without re-scanning. Contact support if you need help.
First check you are on version 1.0.3 or later: earlier installers (1.0.1 and 1.0.2) could fail to open a window, so download the latest from your customer portal. Then try running Wassuply as Administrator (right-click the icon and select "Run as Administrator"). If it still crashes, check that your Windows is up to date. Try disabling antivirus temporarily as some AV software may block the app. If the issue persists, send a crash log from the app's data folder to support@wassuply.com.
This usually indicates the sending account has been soft-banned or restricted by WhatsApp. Check the account health status in Wassuply's dashboard. A yellow or red health indicator means the account needs rest. Pause campaigns on that account for 24 to 48 hours and do not send any messages during that time. See what to do when a WhatsApp account is restricted.
QR codes expire after 60 seconds. Click "Refresh QR" to generate a new one. Make sure your phone and PC are both connected to the internet. Scanning goes faster if you pre-open WhatsApp on your phone to the Linked Devices section before clicking to connect in Wassuply.
