How account warm-up works

What is warm-up and why does a new number need it?#

Warm-up means a WhatsApp number sends and receives ordinary messages before it does any outreach, so its first campaign does not come from a number with no history. A brand-new number that suddenly messages strangers at volume is one of the most common reasons numbers get banned. Warm-up lowers that risk; no tool can remove it.

This page covers local warm-up, where your own numbers message each other. The Warm-up Network pairs your numbers with other customers' numbers. Both count towards the warm-up days in Health & Risk. Local warm-up sends real text messages, runs only while Wassuply is open, and needs an active licence: if your plan lapses, it holds without sending.

How do I start a warm-up session?#

Create a session on the Warmup screen, choose at least two connected numbers and a chat pack, then press Start. A session is a group of numbers that warm up together under one set of rules.

1. 1

   Open the Warmup screen

   In the sidebar, open Warmup → Warmup and click New Session.

2. 2

   Name it and pick numbers

   Type a Session Name, then tick at least two numbers under Select Accounts (min 2). All Connected ticks every connected number, and a group pill ticks a whole group.

3. 3

   Choose the lines

   Under Message Pack, pick one of the Built-in Packs, or switch to Custom and paste your own lines, one per line.

4. 4

   Set pacing and hours

   Set Min Delay, Max Delay, Messages per Account per Day and the Schedule.

5. 5

   Create and start

   Click Create Session, then Start on the session card. Wassuply opens each number's WhatsApp Web session and waits up to about 16 seconds for it to connect.

How does Wassuply decide which number messages which?#

Every number in a session is paired with every other number, and each pair holds its own conversation in strict turns. The editor shows the count as pair conversation(s).

• Turns: after every successful message, the turn passes to the partner.
• One at a time: a number in several pairs sends its messages one after another, never two at once.
• Hand-offs: if the number due to send is at its daily cap, not connected, or held by Smart Send Protection, its partner takes the turn.
• Checks: Wassuply confirms the open chat is the partner's and that the message box holds exactly the chosen line before clicking Send.
• No delivery check: a message counts as sent once Send is clicked. Wassuply does not read WhatsApp's ticks for warm-up.
• First chat: if search cannot find a pair's chat, Wassuply may open it with WhatsApp's click-to-chat link, which reloads that number's WhatsApp Web page.

How is each message chosen, and can lines repeat?#

Each message is a random line, leaving out lines the sending number has already sent in the current run and lines the pair has already exchanged. Lines are not sent in order, so write custom lines that make sense on their own.

Lines do repeat eventually. When a pair runs out of unused lines, Wassuply clears that pair's history and starts the whole list again. With a 76-line pack and 20 messages a day, two numbers use every line in about two days. For long warm-ups, choose Tech & Gadgets or a long custom list.

What does each warm-up setting do?#

Each session has its own delays, daily number and schedule. New sessions start from the defaults in Settings → Warmup.

In Settings → Warmup you can change the defaults (Messages Per Day 1 to 200, Min Delay 5 to 300 seconds, Max Delay 5 to 600 seconds) and turn on Auto-resume warmup sessions on launch, which is off by default.

How do delays, daily caps and active hours work together?#

Delays space out each pair's messages, the daily cap limits each number, and the schedule decides when anything is sent.

• Delays: before each message, a pair waits a random time between Min Delay and Max Delay, counted from its previous message. Each pair keeps its own timer, so a number in several pairs sends more often. After Start, each pair's first message goes out straight away.
• Daily cap: a number stops for the day at the lower of Messages per Account per Day and its own Daily Message Limit, or the Global Daily Send Limit in Settings → Sending (80 by default) if that is 0. The count includes campaign and Warm-up Network messages and resets at midnight.
• When capped: the partner takes the turns. When both are capped, the pair waits for the next day and Wassuply shows a Warmup Daily Limit notification.
• Active hours: outside the window, or at weekends when they are off, pairs check again every minute. A window can cross midnight. Local warm-up ignores the Blackout Hours that campaigns use (see sending safety).

What happens when you pause, stop, edit or close Wassuply?#

Pausing keeps a session's place; stopping and pressing Start again begins a fresh run with an empty message history.

Local warm-up data stays on your computer: sessions, lines, turn order and the messages of the current run. Each send also appears in Activity Logs as a Warmup entry, and Live Activity shows the last 150 messages while the screen is open.

What does the Warmup Progress screen show?#

Warmup → Warmup Progress shows one read-only card per session with its status and today's progress.

Stage label

Early Warm, Building, Established or Full Speed, set by your daily number (up to 15, 40, 80, then above), not by how long the numbers have warmed.

days active

Days since the session was created.

Today's messages

The whole session's sends today against the per-number daily value, so the bar can reach 100% before each number hits its cap.

Send window, Delay range, Schedule, Script lines

The session's settings and line count.

Accounts

Each number's connection dot and its sends today across Wassuply.

How long should a number warm up, and what are the limits?#

Warm a brand-new number for at least 15 days before its first campaign, and 30 days if you can. Wassuply does not ramp the daily number for you: to send more over time, raise Messages per Account per Day yourself.

Health & Risk counts warm-up days from when the number's earliest warm-up session was created, or its first Warm-up Network message if earlier, and shows Ready from day 60. It does not check daily volume, so keep the session running.

• A running session blocks campaigns on its numbers; pause it first (see broadcast campaigns).
• With Smart Send Protection set to enforce, a number at or above the pause score sits out its turns and is retried every 2 minutes.
• Failed sends are retried after 30 seconds, then 2, 5 and 15 minutes, then every 30 minutes.
• 184 Tech & Gadgets lines contain the word stop. With Auto opt-out on replies on, a receiving number can record the sender as opted out in Contacts.
