What are the WhatsApp sending limits in WarmySender?

One connected number may send up to 60 messages a day in total, at most 20 of which may be first messages to people it has never messaged before, and no more than 8 in any rolling hour, with a natural randomized pause of roughly 45 seconds to 2 minutes between messages. New numbers start well under those ceilings and build up over several weeks.

What still works if my WhatsApp number disconnects?

Everything except sending, and nothing is lost. Outreach on that number pauses rather than retrying into a lapsed link, so nobody gets a duplicate and nobody is dropped; your conversation history, prospects, campaign setup and each person's position in the sequence are all preserved. New incoming messages don't reach your WarmySender inbox while it is disconnected — they are still safe on your phone, and reconnecting brings the threads back into sync. Your other numbers and other channels carry on completely normally.

How WhatsApp sending limits keep your number safe

Updated Aug 26, 2026

Every connected number sends inside one budget: up to 60 messages a day in total, of which at most 20 may be first messages to people you have never messaged before, no more than 8 in any hour, and a natural pause of roughly 45 seconds to 2 minutes between messages. New numbers start well under those ceilings and build up over several weeks. Replies you receive never count at all, and a reply you type yourself is never speed-limited. These are ceilings, not settings — WarmySender never loosens them to send faster.

What are the WhatsApp sending limits?

One connected number may send up to 60 messages a day in total, at most 20 of which may be first messages, and no more than 8 in any rolling hour. Those three numbers are the whole budget, and every message a campaign sends draws from them.

Up to 60 messages a day: The total for one number across everything a campaign sends — first messages and follow-ups together.
Up to 20 first messages a day: A first message is the very first message you've ever sent to that phone number. This is a strict slice of the 60, not an extra allowance on top: 20 first messages leaves 40 of the daily budget for follow-ups.
No more than 8 messages an hour: A rolling hourly ceiling that stops a day's budget from going out in one burst. It applies in every case, including on an established number sending at full volume.
Roughly 45 seconds to 2 minutes between messages: A natural, randomized pause. It is never a fixed beat, because a machine-regular rhythm is itself a giveaway.

First messages are budgeted separately because they carry all the risk. A conversation someone already agreed to is unremarkable; a message to a stranger who did not ask for it is what gets a number blocked or reported. So WarmySender spends that part of the budget carefully and keeps the rest for the conversations you've already started.

How does a new number build up to full volume?

A brand-new number starts at 5 first messages and 20 messages a day in its first week, moves to 10 and 40 in its second week, and reaches the full ceiling of 20 first messages and 60 messages a day from its third week onward. You choose how established the number is when you connect it, and that choice sets where the ramp begins.

A brand-new number: Week one: 5 first messages, 20 messages a day. Week two: 10 and 40. Week three and after: the full 20 and 60.
A number with genuine history: Week one: 10 first messages, 30 messages a day. Week two and after: the full 20 and 60. Even a real, well-used number benefits from one week of easing into automated sending.
"My number is established": An explicit option that starts straight at the ceiling — 20 first messages and 60 messages a day from the very first message. The ceiling is still the ceiling: the hourly limit and the pause between messages apply exactly the same, and there is no mode above this one.

Answer that question honestly. Choosing "established" for a number you bought last week doesn't make it a well-used number, and a fresh number pushed to the ceiling on day one is the single most reliable way to lose it. See how to connect your WhatsApp number for where that question appears.

How soon after connecting should I start a campaign?

Give a freshly connected number a day of normal use before you point a campaign at it. Chat with a few real contacts, let the connection settle, then launch. Connecting takes about a minute, but there is no prize for starting outreach inside that minute — and a number that starts messaging strangers within moments of being linked is the most conspicuous pattern there is.

If the number itself is new rather than just newly connected, be far more patient than that. Use it as an ordinary phone number for a while first — real conversations, real contacts, real inbound messages — and only then start outreach on the gentlest ramp. Nearly every restriction story is the same story: a fresh number that went straight to volume.

Do replies count against my daily limit?

Replies you receive never count against anything. A reply you type yourself does draw from your daily total — it is still a message leaving your number — but it is never speed-limited: it goes out the moment you hit send, with no pacing pause and no waiting on the hourly ceiling.

A reply is also never a first message, so it never touches the 20-a-day first-message allowance. That allowance is reserved entirely for reaching out to someone new, which is the part that carries the risk.

In practice this means conversations move at your speed, not the scheduler's, from the WhatsApp tab of your Inbox. Only campaign outreach is paced: the first message to someone new, and the scheduled follow-ups after it.

What still works if my number disconnects?

Everything except sending, and nothing is lost. While a number is waiting to be reconnected, WarmySender pauses outreach on it rather than retrying into a lapsed link, so nobody gets a duplicate and nobody is dropped from a sequence. Your conversation history, your prospects, your campaign setup and each person's exact position in that campaign are all preserved.

Two things do stop while a number is disconnected: no campaign messages go out on it, and new incoming messages don't reach your WarmySender inbox — they're still perfectly safe on your phone, and reconnecting brings those threads back into sync. Everything else in your account is untouched, including your other numbers and your other channels, which carry on completely normally. Reconnect by scanning a fresh code and sending picks up from the same spot on its normal schedule.

A pause like this never costs you budget either. Days when a number couldn't send are simply days it didn't send; the daily allowance doesn't accumulate into a backlog to be caught up on, because a catch-up burst is exactly what the limits exist to prevent.

What happens if nobody replies to my first messages?

WarmySender automatically tightens your first-message allowance until your reply rate recovers. If the people you're reaching out to are consistently not replying, that's the earliest honest signal that your list or your opener isn't landing — and it's also the pattern that leads to blocks and reports.

The tightening is automatic, temporary, and only ever goes one direction: it lowers the number of new conversations a number may start each day, and it lifts by itself once replies pick up again. It never touches your ability to answer people who wrote to you.

If it arms, treat it as feedback rather than a fault. The fix is almost always a better-qualified audience or a more relevant first message — see how to build your WhatsApp audience and the message advice in how to run a WhatsApp campaign.

How long can a WhatsApp message be, and can I attach files?

A message can be up to 4,096 characters, and you can attach up to 5 files of up to 15MB each. Those are the practical shape limits for a single WhatsApp message.

Shorter almost always works better for a first message. WhatsApp is a personal, conversational channel — a two-line message that reads like a person wrote it gets replies; a 4,000-character pitch reads like a broadcast and gets blocked. Use the room you have for genuine personalization, not for length.

Attaching files doesn't cost you anything extra against the budget: a message with five attachments is one message, exactly like a message with none. What it does cost you is goodwill if it's the first thing you send. An unexpected file to download from an unknown number is a common reason people block a sender, so save attachments for after someone has replied.

Which actions count against my daily budget?

Only messages that actually leave your number. Everything else you can do in a conversation — reacting, editing, deleting, pinning, muting, archiving, marking a thread read or unread — sends no new message and spends none of your allowance.

Counts, and is paced: Campaign messages: the first message to someone new, and the scheduled follow-ups after it. These draw on the daily total, obey the hourly ceiling, and go out with the 45-second-to-2-minute pause between them. A first message also draws on the separate first-message allowance.
Counts, but is never paced: A reply you type yourself. It's still a message leaving your number, so it draws on the daily total — but it goes out the instant you hit send, with no pause and no waiting on the hourly ceiling, and it never counts as a first message. Conversations move at your pace, not the scheduler's.
Doesn't count at all: Replies you receive. Emoji reactions, in either direction. Editing a message you've sent (within WhatsApp's 15-minute window) or deleting one. Pinning, muting, archiving, and marking a thread read or unread.

One consequence worth knowing: because a reaction isn't a message, it isn't treated as a reply either. A prospect who taps a thumbs-up on your message without answering it stays in their sequence and receives the next step as scheduled — only an actual reply stops the automated follow-ups.

Can I raise these limits?

No. There is no setting, plan, or support request that raises a number's limits, and WarmySender never loosens them to send faster. If you want more WhatsApp volume, connect another number — each connected number has its own completely independent daily, first-message and hourly budget.

You can always aim lower than the ceiling, and for a new or recovering number that's a good idea. What you can't do is aim higher. The reason is blunt: a restricted WhatsApp number is your own phone number, and it isn't something anyone can restore for you.

Adding numbers is also the honest way to scale. Two numbers running gently reach more people, more safely, than one number pushed hard. Each additional number is a seat at $15/month, $120/year, or $288 every 3 years, on the billing page.

Why is my WhatsApp campaign sending so slowly?

Because the pacing is working. Messages go out with a random 45-second-to-2-minute gap, under an 8-an-hour ceiling, so a campaign trickles out through the day rather than firing in a batch. If a number hits its hourly ceiling it waits for the next hour; if it hits its daily ceiling it waits for tomorrow.

Nothing is lost while it waits. Prospects stay enrolled at exactly the step they were on and sending resumes on its own — the limits pace your outreach, they never drop people. A brand-new number on the first week of the ramp will feel especially gentle, and that is the point.

Common questions about WhatsApp limits

Can I raise the 60-a-day or 8-an-hour limit?

No. They're hard ceilings rather than settings, and nothing in the product or in support will lift them. You can configure a campaign to aim lower — sensible for a new number — but nothing pushes a number above 60 messages a day, 20 first messages, or 8 in an hour. For more total reach, connect additional numbers; each has its own independent budget.

Is the 20 first messages a day on top of the 60, or part of it?

Part of it. First messages are a strict slice of the same 60-a-day budget, not a separate allowance. If a number sends 20 first messages, it has 40 messages left that day for follow-ups and everything else.

Does replying to someone use up my daily budget?

Replies you receive never count against anything. A reply you type yourself draws from the daily total — it is a message leaving your number — but it is never speed-limited and never counts as a first message, so conversations move at your speed rather than the scheduler's. Only campaign outreach is paced: the first message to someone new and the scheduled follow-ups after it.

How long until a new number can send at full volume?

Three weeks for a brand-new number: 5 first messages and 20 messages a day in week one, 10 and 40 in week two, then the full 20 and 60 from week three. A number with genuine history takes one week — 10 and 30, then full. Don't rush it; the ramp is what keeps a new number alive.

What happens to my prospects when a number hits its daily limit?

Nothing is lost. When a number reaches its daily or hourly ceiling, outreach pauses and every prospect stays enrolled at the exact step they were on. Sending resumes automatically the next hour or the next day, right where it left off.

Why is my first-message allowance suddenly lower?

Most likely because your first messages aren't getting replies, so WarmySender has automatically tightened the allowance until the reply rate recovers. It's temporary and it lifts by itself. The lasting fix is a better-qualified list or a more relevant opener, not more volume.

Will running more numbers get me more reach safely?

Yes — that's the safe way to scale. Each connected number has its own independent budget, so two numbers can safely do more combined outreach than one, without either exceeding its limit. That is far safer than trying to push a single number harder, which nothing in WarmySender will let you do anyway.

Can my WhatsApp number get banned?

Any number can be restricted if it behaves like a broadcaster, which is precisely what the conservative limits, the ramp, the natural pauses and the automatic tightening are designed to prevent. Staying inside the defaults, being honest about how established a number is, keeping the number in normal everyday use, and messaging people with a genuine reason to hear from you are the best protection. If WhatsApp pushes back, WarmySender stops rather than retrying into it.

Do emoji reactions, edits or deletes use up my allowance?

No. None of them sends a new message, so none of them touches your daily total, your first-message allowance or your hourly ceiling. The same goes for pinning, muting, archiving and marking a thread read or unread. Only a message that actually leaves your number counts.

Does attaching files to a message use more of my budget?

No. A message with five attachments counts as one message, exactly like a message with none — the limits count messages, not megabytes. The ceilings on attachments themselves are up to 5 files of up to 15MB each, alongside up to 4,096 characters of text.

Can an AI agent raise my WhatsApp limits?

No. An agent can create, launch, pause and resume campaigns and enrol people in them, but it never sends a message itself and it can never raise a limit — there is no tool for it, on purpose. Whatever an agent sets running is handed to WarmySender's scheduler, which paces every message inside the same ceilings and the same ramp as if you had launched it yourself.
