How Threadwire keeps your WhatsApp number safe
Your WhatsApp number is where your customers find you, and a banned number loses every chat it ever had. That is why every message, on every plan, goes through the same protection. You can tighten it and adjust it within safe limits; it can never be switched off.
- On every plan
- Always on
- Our limits never stop replies
Why numbers really get banned
WhatsApp does not ban you for messaging someone new. It bans patterns that look like spam: lots of messages to people who did not ask for them, sent the way a machine sends them. A business having real conversations with its customers looks nothing like that.

When the account is created
A new number is checked from the moment it registers, before it sends anything.
While it sends
How fast, how much and to whom. A number that suddenly sends like a machine stands out.
When people react
Blocks and reports are the strongest signal of all. People who wanted your message do not report it.
The warning signs WhatsApp looks for
None of these is a problem on its own. Together, they are what spam looks like, so Threadwire is built to keep your number well away from them.
- People blocking or reporting you

- Contacts far from the number's country
- No profile picture or name

WhatsApp usually warns before it bans
A number rarely goes from fine to banned overnight. WhatsApp tightens step by step, and every step is a chance to slow down.
A pause on new chats
For a while, the number cannot start chats with new people. Replies still work.
A cap on unanswered messages
A limit on messages to people who have not replied, with two warnings as it fills up.
A temporary ban
The number is locked for a time.
A permanent ban
The number, and every chat on it, is gone.
A brand-new number that messages lots of strangers can skip all of this and be banned straight away. That is why new numbers start slowly with us.
How Threadwire protects every number
Each warning sign has an answer built into every message we send. The figures below are the recommended settings every number starts with.
New numbers start slowly
A newly linked number may message 10 new people a day, rising to 50 over its first 14 days, as WhatsApp comes to trust it.
A brand-new number sending a lot at once
Volume grows with trust
Messages that are not replies are capped at 50 a day at first, rising to 200, with no cap after 14 days. Replies never count.
A brand-new number sending a lot at once
A human pace
First messages to new people go 30 to 60 seconds apart, with a 5 to 10 minute break after every 10. Anyone who has not written in the last hour gets at most 4 messages an hour.
Robot-like speed and timing
Read and typing, like a person
Every message to a person or a group shows "typing…" first, for longer when the message is longer. The chat is marked as read before your team's reply, just as a person would do it.
Robot-like speed and timing
Quiet at night
No first messages to new people at night, in each number's own time zone. Replies still go out.
Robot-like speed and timing
A reply score on every number
We watch how many of the people a number messaged first actually answer. Under 20%, its new chats are halved; under 5%, they pause for up to a week. Replies are never limited by this.
Many messages to people who never wrote to you and do not answer
No chasing people who do not answer
Someone who never wrote to you gets at most 3 messages a day until they answer: your message, its file and one reminder, say. If they still do not answer, none of your numbers can write to them first again until 7 days after your last message.
Many messages to people who never wrote to you and do not answer
No copy-and-paste blasts
One text, or one file, may open at most 5 new chats a day across all your numbers. A message with the person's name or order in it is different each time, so this never holds it back.
The same text sent to many people
Broadcasts only to people who opted in
A broadcast reaches only people who wrote to the number, or saved contacts the business chooses (then as new chats, with every limit), never a bought list. Each person gets their own message, one at a time, at least 20 seconds apart, in daytime, with a line saying how to opt out. It stops by itself if WhatsApp warns the number or more than 2% of people reply STOP.
Bulk messages to people who did not ask for them
Short, safe first messages
A first message to someone new may be at most 600 characters, and its links must be secure (https).
Suspicious links, or links without https
Opt-outs honoured
Anyone who writes "STOP" (or its Arabic) is not messaged again from any of your numbers until they write to you.
People blocking or reporting you
Contacts abroad count double
A new person in another country counts as two against the day's limit, so a number stays mostly local, like a real one.
Contacts far from the number's country
Groups: only people who know you
Only people who have written to the number, or are saved on its phone, can be added to a group. Everyone else can be sent the invite link instead.
Adding strangers to groups
WhatsApp's warnings, obeyed
We read WhatsApp's own warnings for every number as they come, and every hour. At the first, new chats slow to half; at the second, they stop. We never relink a number to dodge a warning: that only makes it worse.
WhatsApp's own warnings
Profile checked
We check that every number has a profile picture and a name, and tell you if one is missing.
No profile picture or name
A network address of its own
A dedicated address for each number in its own country, instead of one server address shared with other numbers. Available on request.
Sharing a network with banned numbers
And you always know where you stand
The safety meter
Every number gets a safety score out of 100, updated every hour from its age, its reply score, WhatsApp's warnings, failed sends, opt-outs and more. Each point lost comes with its reason and the one next step to take, and your team gets an email if it drops to "use caution".
Guided warm-up
A new number's page shows its warm-up day by day: today's allowances, and the simple steps that build trust, ticking themselves off as you go.
You set the dial, within safe limits
On each number's page you can make any protection stricter: longer quiet hours, fewer new people a day, a slower pace, fewer follow-ups. A few can be loosened a little, never past a safe floor. Quiet nights last at least 6 hours, and first messages never go faster than 30 to 60 seconds apart. A phone with a long WhatsApp history still warms up, from day 8. Nothing switches protection off.
Automatic warm-up
Where available, your own numbers chat with each other in their first 14 days, at a natural pace, so each builds a history of normal use. It runs only when each number has its own address in its own country.
Our honest promise
Nobody who links a number the way WhatsApp Web does can promise it will never be banned: only Meta's official WhatsApp Business API removes that risk entirely. What we do promise is this: for normal business use, a ban becomes much less likely. And any message that breaks the rules on this page is held or refused, with the reason, instead of being sent.
Five habits that keep a number safe
Our protection does the heavy lifting. These habits do the rest.
Let people write first
Share your number's chat link or QR code on your website, receipts and social pages. People who write first are never limited as new people.
Message only people who expect it, and make it personal
Write to customers who gave you their number and know your business. Use their name and their order, never one text pasted to a list.
Reply quickly
A conversation where both sides talk is the clearest sign of a real business. Fast answers keep it that way.
Give a new number a face, and time
Set a profile picture and your business name, use a real, established SIM rather than a virtual number, and let a new number warm up for 14 days.
If WhatsApp warns, slow down
Warnings lift on their own. Never switch, log out or relink a number to get around one: that makes things worse.
For developers: a message that is held or refused says why, in plain words, in its error. Each number's protection field in the API shows its limits, warm-up day, reply score and safety meter. WhatsApp's errors 463 (new chats paused) and 475 (the cap reached) are handled for you: new chats rest, and the session is never restarted. Read the API reference →
