Everything you need to know about how WarmySender keeps your WhatsApp number safe, and what it can actually do. Daily limits, the ramp for a new number, what counts against your budget, attachments and voice notes, reactions, group chats and read receipts — and the honest answer on restriction risk.
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, and no more than 8 in any rolling hour. Messages go out one at a time with a natural, randomized pause of roughly 45 seconds to 2 minutes — never a machine-regular beat. The first-message allowance is a strict slice of the daily total, not an extra allowance on top, so 20 first messages leaves 40 for follow-ups. New numbers start well below all of that and build up over several weeks. These are ceilings, not settings: nothing in the product, in a plan, or in support raises them.
Safety wins over speed, every time. Your number sends under conservative ceilings (60 messages a day, 20 first messages, 8 an hour), with randomized 45-second-to-2-minute pauses, a multi-week ramp for new numbers, and a separate, stricter budget for first messages — because a message to a stranger who did not ask for it is what gets a number reported, not a conversation someone already agreed to. If your first messages stop earning replies, the first-message allowance tightens automatically until the rate recovers. And if WhatsApp pushes back, WarmySender stops rather than retrying into it. WhatsApp is deliberately the strictest channel on the platform, because the account at risk is your own phone number.
Never — there is no password anywhere in this flow. Open WhatsApp → Numbers in WarmySender, click Connect number, then on your phone go to Settings → Linked devices → Link a device and scan the code on screen. It takes about a minute. If you can’t scan, switch to the “Type a code” option: enter your number in full international format (for example +14155550123) and you’ll get a short code to type into WhatsApp instead. WarmySender becomes a linked device, exactly like WhatsApp Web — you can see it listed under Linked devices on your phone and remove it yourself at any time. Step by step: how to connect your WhatsApp number.
Not for your campaign to send. Once your number is linked, WarmySender works as its own device: messages go out and replies arrive even while your phone is asleep, out of signal, or charging in another room. WhatsApp does expect your phone to come online now and then — leave it offline for a couple of weeks and WhatsApp signs out every linked device, this one included, and you’d simply reconnect by scanning a fresh code. Keeping the number in normal everyday use is good for its health anyway.
Yes. Connecting adds one more linked device — your phone stays signed in, and so do WhatsApp Web and the desktop app. Nothing is taken away from you. Keep chatting normally: a number carrying genuine everyday conversations is a healthier outreach number than one that only ever sends first messages. Messages you send from your phone show up in your WarmySender inbox too, so each thread stays complete no matter where you typed it.
Give a freshly connected number a day of normal use before you launch a campaign — chat with a few real contacts, let the connection settle, then start. Connecting takes a minute, but there’s no prize for launching within that minute. If the number itself is new rather than just newly connected, be far more patient: use it as an ordinary phone number for a while first, with real conversations and real contacts, and then start outreach on the gentlest ramp. Every restriction story starts with a fresh number that went straight to volume.
A brand-new number starts at 5 first messages and 20 messages a day in week one, moves to 10 and 40 in week two, and reaches the full ceiling of 20 first messages and 60 messages a day from week three onward. A number with genuine history starts at 10 and 30 for one week, then goes to full — even a well-used number benefits from a week of easing into automated sending. There is also an explicit “my number is established” option that skips the ramp and starts straight at the ceiling; the ceiling is still the ceiling, so the hourly limit and the pause between messages apply from the very first message. You pick when you connect, so answer honestly: choosing “established” for a number you bought last week doesn’t make it well-used.
Replies you receive never count against anything at all. A reply you type yourself does draw from your daily total — it’s 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. And a reply is never a first message, so it never touches your first-message allowance. Only campaign outreach is paced: the first message to someone new, and the scheduled follow-ups after it.
Almost always because your first messages aren’t earning replies. When the trailing reply rate on new conversations falls too low, WarmySender automatically tightens how many new conversations that number may start each day — a temporary, one-directional adjustment that lifts by itself once replies pick up. It never touches your ability to answer people who wrote to you. Treat it as early feedback rather than a fault: a number whose cold openers are being ignored is a number heading for blocks and reports. The lasting fix is a better-qualified audience or a more relevant first message, never more volume. The other reason an allowance looks low is simply that the number is still on its ramp.
No. Your conversation history, your prospects, your campaign setup, and each person’s exact position in the sequence are all preserved. 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. Reconnect by scanning a fresh code and sending picks up from the same spot on its normal schedule. New incoming messages don’t reach your WarmySender inbox while the number is disconnected — they’re still safe on your phone, and reconnecting brings the threads back into sync.
Removing WarmySender under Settings → Linked devices on your phone does the same thing as clicking Disconnect in WarmySender: outreach on that number stops immediately and everything else is kept for whenever you reconnect. Changing your WhatsApp number is a bigger event — WhatsApp unlinks every device when you switch numbers, and the new number is a new identity with no history behind it. Connect it as a new number and let it ramp from the start; the conversations on the old number stay with the old number. One thing to note: disconnecting a number and removing its seat are separate actions, so if you’re stepping away from WhatsApp outreach entirely, also reduce your seats on the billing page.
No — campaigns are strictly 1:1 and never message a group. Groups you’re already in appear in your WarmySender inbox read-only, so you can follow along, but you reply to them from WhatsApp on your phone. A message in a group is also never treated as a reply, so an unrelated group thread can never stop someone’s sequence by accident. This is deliberate: unsolicited group messaging is one of the fastest routes to a reported, restricted number, and WhatsApp outreach only works because it stays personal.
Opening a conversation in WarmySender does not send a read receipt to the other person — marking a thread read here only clears your own unread badge. Whether someone sees the blue ticks depends on your normal WhatsApp read-receipt setting and whether you open the chat on your phone. In the other direction, your own outbound messages show their delivered and read state in the WarmySender inbox whenever the recipient has receipts turned on, so you can tell a message that landed and was read from one that’s still waiting.
Yes. A message can carry up to 5 files of up to 15MB each — photos, PDFs, videos and audio clips — both in a campaign’s message step and when you reply from the inbox. Files people send you are downloadable from the conversation too. One piece of advice worth taking: don’t lead with an attachment. A first message that opens with a file to download reads like a broadcast, and that’s the fastest way for a cold opener to be ignored or reported. Send the file once the conversation is underway and they’ve asked for it — your reply rate on first messages is also the signal that governs how many new conversations your number may start. More on the message step: how to run a WhatsApp campaign.
Yes — record one straight in the inbox reply box and it arrives as a real voice note, the round play bubble, rather than a file attachment. It’s a genuinely good reply to someone who has already answered you: it’s personal, it’s hard to fake at scale, and it tends to get a response. Two practical notes. It’s a reply tool, not a cold-open tool — a voice note as the opening message to a stranger is intrusive and lands badly. And if your browser records in a format WhatsApp can’t play, WarmySender tells you before anything is sent, so you can switch browser or attach an audio file instead.
Both. Pick an emoji on any message and the reaction appears on the other person’s phone exactly as it would if you had tapped it in WhatsApp, and reactions people leave on your messages show up here too. You can also quote a specific message when you reply, so a long thread stays readable. A reaction is not a message: it doesn’t spend any of your daily sending allowance, and it isn’t treated as a reply in either direction — if a prospect only reacts to your message instead of answering it, their sequence carries on as before.
Yes, inside WhatsApp’s own rules. You can edit one of your own sent messages for 15 minutes after it goes out — that window is WhatsApp’s, not ours, and once it closes the edit is refused with a plain explanation rather than failing quietly. Deleting removes the message for everyone in the conversation, exactly as deleting it on your phone would. Neither an edit nor a delete counts as a new message against your daily allowance.
No. WarmySender works with the normal WhatsApp app on your phone, and it makes no difference whether that’s regular WhatsApp or the WhatsApp Business app — both connect the same way, both send the same kinds of messages, and both sit under exactly the same limits and the same ramp. There are no pre-approved message templates to submit, no per-message fees, and no approval process to wait through: you write the message in plain language, the way you would write it yourself. If your number is registered as a business one, WarmySender shows a small Business chip on its card — that’s a label, not a different set of rules.
One seat runs one number, and a number is connected once. Your teammates don’t need their own connection: everyone in your workspace works out of the same WhatsApp inbox and can reply from that number, so a shared team number really is shared. What you can’t do is connect the same number twice to get twice the volume — the daily, first-message and hourly budgets belong to the number, not to the seat. More volume always means another number on another seat.
Yes. Your phone, WhatsApp Web and WarmySender are all linked devices on the same account, so a thread reads the same wherever you open it. That covers the case that matters most: if you answer a prospect from your phone rather than here, their automated follow-ups stop just as they would if you had typed the reply in WarmySender. You never have to remember which device you used.
Recent conversations on the number come across when you connect, so the inbox isn’t empty on day one and someone who has messaged you before arrives with their history attached instead of as a blank thread. If one conversation looks out of date you can refresh that single thread on demand. A conversation being visible here never enrols anyone in anything — WarmySender only messages people who are in a campaign audience you built yourself. See how to build your WhatsApp audience.
All four. The WhatsApp tab of your inbox has the housekeeping you would expect: pin the threads you’re working, archive the ones you’re finished with, mute the noisy ones, and mark a thread unread to come back to it later. None of it changes a campaign — muting a conversation doesn’t pause anyone’s sequence and archiving doesn’t remove them from it. And opening a thread here still never sends a read receipt to the other person.
Every message you send carries its own state in the inbox — sent, delivered, read — whenever the other person has receipts turned on, and it’s worth reading before you decide a follow-up is warranted. A message that was delivered and read but not answered is a completely different situation from one that never got delivered. A message that stays undelivered usually just means their phone hasn’t been online, but it can also mean the number isn’t on WhatsApp at all, or that they have blocked you. Nothing checks a number against WhatsApp before you send, so someone who turns out not to be on it is quietly skipped from then on rather than retried.
It shouldn’t, and a lot of the design goes into that. Messages leave one at a time with a randomized 45-second-to-2-minute gap rather than a machine-regular beat, the typing indicator runs for a length that varies with the message instead of the message simply appearing, merge fields make each one genuinely different, and A/B variants stay consistent per person so nobody ever gets two different voices from you. None of that rescues a bad message, though. What most makes a message read as automated is that it plainly wasn’t written for the person receiving it.
An agent can run the campaign; it never sends the message. Claude, ChatGPT, Cursor, Codex, OpenClaw, Hermes Agent — or any agent that speaks MCP — can create a WhatsApp campaign, launch it, pause and resume it, and enrol people in it, all in plain language. What an agent cannot do is send a message to anyone directly, and it can never raise a limit: creating or launching only hands the campaign to WarmySender’s scheduler, which paces every message inside the same daily, first-message and hourly ceilings no matter who or what set it running. Connecting and disconnecting a number stays in the app deliberately — it’s the one thing that isn’t an agent tool.
Yes — any WhatsApp number can be restricted, and we want to be blunt about this: a restricted number is your own phone number, and it’s on you. WarmySender cannot undo it, appeal it for you, or get it back. What we can do is make it unlikely, and that’s what everything here is for: conservative ceilings, a separate stricter budget for first messages, randomized pacing, a multi-week ramp, automatic tightening when replies dry up, and stopping rather than retrying when WhatsApp pushes back. What you do matters even more. Message people with a genuine reason to hear from you, be honest about how established the number is, keep it in everyday use, and stop the moment someone asks you to.
Cold email is a volume channel; WhatsApp is emphatically not, and treating it like one is how numbers get lost. A mailbox sends thousands of emails a month — a WhatsApp number can start at most 20 new conversations in a day. WhatsApp also lands in a space people guard: reply rates are high, tolerance for irrelevance is close to zero, and the consequence of getting it wrong isn’t a spam folder, it’s a block-report against your own phone number. Use it for people who plausibly expect to hear from you — event follow-ups, warm introductions, conversations already underway — and let email carry the volume. WarmySender runs cold email, email warmup, LinkedIn, WhatsApp and Instagram on one platform, so a reply on any channel stops the automated follow-ups on all the others.
WhatsApp outreach is a paid add-on. There is a limited-time launch offer running through September 25, 2026: monthly seats added in that window are $10 per seat per month and keep that rate for as long as you keep them. The regular price is $15 per seat per month or $120/seat per year, where one seat runs one number. Add a seat on the billing page, connect your number by scanning the code from Linked devices on your phone, and answer the short question about how established the number is so it starts at the right pace. Then bring your audience — phone numbers in full international format, uploaded as a list or pasted into the campaign wizard, since there is no WhatsApp number search and never will be — and build a short sequence under Campaigns → New campaign → WhatsApp. A first message, a wait, and one gentle follow-up is a genuinely good first campaign. From there the pacing, the ramp and the limits are handled for you. Messages can run up to 4,096 characters, but the short ones get the replies.
