One campaign, hundreds or thousands of individual chats.<\/p>\n\n<p class=\"wp-block-paragraph\">Because each message lands as a personal one-to-one chat, bulk WhatsApp messaging behaves differently from mass email. Messages can carry images, video, documents, and <a href=\"https:\/\/sinch.com\/fr\/blog\/api-whatsapp-business\/\">interactive buttons<\/a>, and recipients can reply, ask questions, and buy \u2013 right in the thread.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>One thing bulk messaging is not: spam.<\/strong> WhatsApp requires businesses to collect an opt-in before sending proactive messages, and it actively monitors quality signals like blocks and reports. That discipline is why the channel&rsquo;s engagement stays so high.<\/p>\n\n<h2 class=\"wp-block-heading\">How to send bulk messages on WhatsApp: 2 official options<\/h2>\n\n<p class=\"wp-block-paragraph\">There are exactly two Meta-approved routes to sending in bulk. Which one fits depends on how many people you need to reach and how much personalization you need.<\/p>\n\n<h3 class=\"wp-block-heading\">1. Broadcast lists in the WhatsApp Business app<\/h3>\n\n<p class=\"wp-block-paragraph\">The free <a href=\"https:\/\/sinch.com\/fr\/blog\/comptes-whatsapp-standard-ou-whatsapp-business\/\">WhatsApp Business app<\/a> includes a broadcast feature: build a list, write your message, and it goes out to everyone on it as an individual chat.<\/p>\n\n<p class=\"wp-block-paragraph\">It&rsquo;s genuinely useful for very small businesses \u2013 and genuinely limited:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>256 contacts per broadcast list<\/strong>, and you&rsquo;ll need multiple lists (with manual upkeep) beyond that.<\/li>\n\n\n\n<li><strong>Recipients must have your number saved<\/strong> in their contacts, or your broadcast never reaches them.<\/li>\n\n\n\n<li><strong>No personalization, automation, or analytics<\/strong> \u2013 you won&rsquo;t know who read or clicked.<\/li>\n\n\n\n<li><strong>One phone, one user<\/strong> \u2013 built for a single person, not a team.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">If your contact list fits comfortably under a few hundred people and you know them personally, start here. If not, the ceiling shows up fast.<\/p>\n\n<h3 class=\"wp-block-heading\">2. The WhatsApp Business Platform<\/h3>\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/sinch.com\/fr\/messages\/api-whatsapp-business\/\">WhatsApp Business Platform<\/a> is Meta&rsquo;s enterprise-grade route, accessed through a Business Solution Provider (BSP) like Sinch. It&rsquo;s built for exactly the job the app can&rsquo;t do:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Reach thousands of opted-in customers<\/strong> per campaign \u2013 capacity grows as your quality holds up (limits below).<\/li>\n\n\n\n<li><strong>Personalization at scale<\/strong> \u2013 dynamic fields for names, order details, and recommendations, powered by your CRM or e-commerce data.<\/li>\n\n\n\n<li><strong>Team inboxes, chatbots, and automation<\/strong> for handling the replies a good campaign generates.<\/li>\n\n\n\n<li><strong>Delivery, read, and click analytics<\/strong> for every send.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">The trade-off: proactive messages use pre-approved <a href=\"https:\/\/sinch.com\/blog\/everything-you-ever-wanted-know-about-whatsapp-business-templates\/\" data-type=\"link\" data-id=\"https:\/\/sinch.com\/blog\/everything-you-ever-wanted-know-about-whatsapp-business-templates\/\">message templates<\/a> and per-message pricing \u2013 both covered below.<\/p>\n\n<h3 class=\"wp-block-heading\">What about unofficial bulk-sender tools?<\/h3>\n\n<p class=\"wp-block-paragraph\">Search this topic and you&rsquo;ll find browser extensions and modified apps promising bulk sending with no approval process. They all work the same way: by violating WhatsApp&rsquo;s terms of service. Meta actively detects them, and the predictable outcome is <a href=\"https:\/\/sinch.com\/fr\/blog\/compte-whatsapp-business-banni\/\">a banned WhatsApp Business account<\/a> \u2013 along with handing your customers&rsquo; phone numbers to an unaccountable third party. In <em><a href=\"https:\/\/sinch.com\/fr\/etat-communications-clients\/?utm_content=blog&amp;utm_term=&amp;intcmp=GL-25-Brn_SCC_blog_content\">The state of customer communications<\/a><\/em>, 44% of consumers named security and privacy their biggest digital-communication challenge. Lose their trust there and no open rate will win it back.<\/p>\n\n<h2 class=\"wp-block-heading\">How many bulk messages can you actually send?<\/h2>\n\n<p class=\"wp-block-paragraph\">It&rsquo;s the question sales pages skip. Here are the real numbers.<\/p>\n\n<p class=\"wp-block-paragraph\">On the Business Platform, Meta caps how many <strong>unique customers<\/strong> you can start conversations with in a rolling 24-hour period. Every verified business starts with a limit and earns higher tiers automatically:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>1,000 unique customers per 24 hours<\/strong> \u2013 the starting tier<\/li>\n\n\n\n<li><strong>10,000 per 24 hours<\/strong><\/li>\n\n\n\n<li><strong>100,000 per 24 hours<\/strong><\/li>\n\n\n\n<li><strong>Unlimited<\/strong><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Your limit <a href=\"https:\/\/developers.facebook.com\/documentation\/business-messaging\/whatsapp\/messaging-limits\">upgrades automatically<\/a> once you&rsquo;ve messaged 2,000 unique customers within a period while keeping message quality healthy \u2013 Meta now re-evaluates accounts as often as every six hours. Since October 2025, limits apply per business portfolio rather than per phone number, so adding numbers won&rsquo;t raise the ceiling.<\/p>\n\n<p class=\"wp-block-paragraph\">The other half of the equation is your <strong>quality rating<\/strong>. Meta scores every sending number based on blocks, reports, and engagement over the trailing seven days. Let quality slide and your limit can drop; keep sending messages people want, and it climbs. <strong>Your sending capacity is a direct function of how good your messages are.<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Replies are different: once a customer messages you, a 24-hour customer service window opens in which you can respond freely, without templates. Every new inbound message resets it.<\/p>\n\n<h2 class=\"wp-block-heading\">Sending bulk messages in the U.S.: know the marketing pause<\/h2>\n\n<p class=\"wp-block-paragraph\">If your audience includes U.S. phone numbers, there&rsquo;s a rule you must plan around: <strong>since April 1, 2025, Meta has paused marketing template messages to U.S. numbers<\/strong>, and as of August 2026 the pause remains in effect with <a href=\"https:\/\/help.manychat.com\/hc\/en-us\/articles\/19328856186780-Temporary-pause-on-WhatsApp-Marketing-Templates-in-the-US\">no announced end date<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">What that means in practice for U.S. recipients:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Paused:<\/strong> proactive marketing templates \u2013 promotions, product announcements, win-back campaigns.<\/li>\n\n\n\n<li><strong>Still available:<\/strong> utility templates (order confirmations, shipping updates), authentication templates like <a href=\"https:\/\/sinch.com\/fr\/blog\/comment-envoyer-otp-sur-whatsapp\/\">one-time passwords<\/a>, and free-form replies inside the 24-hour customer service window.<\/li>\n\n\n\n<li><strong>Still available:<\/strong> Click-to-WhatsApp ads, which open a 72-hour free messaging window when a customer taps through.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Bulk marketing campaigns to opted-in audiences in Latin America, Europe, India, and the rest of the world are unaffected. If the U.S. is your core market, lean on utility and authentication use cases (or a channel like RCS) for now \u2013 and re-check the pause before every campaign, because Meta can lift it at any time.<\/p>\n\n<h2 class=\"wp-block-heading\">How to send bulk messages on WhatsApp in 6 steps<\/h2>\n\n<p class=\"wp-block-paragraph\">Here&rsquo;s the path from zero to your first compliant campaign on the Business Platform.<\/p>\n\n<h3 class=\"wp-block-heading\">1. Collect real opt-ins<\/h3>\n\n<p class=\"wp-block-paragraph\">Before anything else, you need permission. Collect opt-ins wherever customers already interact with you \u2013 checkout flows, account signup, a website widget, a QR code on packaging \u2013 and be specific about what they&rsquo;re signing up for. Keep a record of when and how each opt-in was collected, honor opt-outs immediately, and never buy contact lists. Beyond being WhatsApp policy, consent is what separates a welcome message from a blocked number.<\/p>\n\n<h3 class=\"wp-block-heading\">2. Set up your WhatsApp Business account through a BSP<\/h3>\n\n<p class=\"wp-block-paragraph\">To use the Business Platform you&rsquo;ll work with a BSP like Sinch. You&rsquo;ll verify your business with Meta, register a dedicated phone number, and create your <a href=\"https:\/\/sinch.com\/fr\/blog\/comment-fonctionne-compte-whatsapp-business\/\">WhatsApp Business account<\/a> (WABA). With embedded signup, setup takes minutes \u2013 and a verified business profile means customers see who&rsquo;s messaging them, not a bare number.<\/p>\n\n<h3 class=\"wp-block-heading\">3. Create and submit your message templates<\/h3>\n\n<p class=\"wp-block-paragraph\">Proactive bulk messages use templates: pre-approved message structures with {{placeholders}} for personalization. Write your message, mark its category (marketing, utility, or authentication), add any media, buttons, or quick replies, and submit \u2013 Meta&rsquo;s review typically takes minutes to a few hours. Once approved, a template can be reused across campaigns indefinitely. <a href=\"https:\/\/sinch.com\/blog\/everything-you-ever-wanted-know-about-whatsapp-business-templates\/\">Well-structured templates<\/a> with clear value and an obvious action are also what keep your quality rating healthy.<\/p>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"396\" src=\"https:\/\/sinch.com\/wp-content\/uploads\/2025\/09\/SI-Blog-how-to-send-bulk-messages-on-whatsapp.rewrite.png\" alt=\"\" class=\"wp-image-204698\" srcset=\"https:\/\/sinch.com\/wp-content\/uploads\/2025\/09\/SI-Blog-how-to-send-bulk-messages-on-whatsapp.rewrite.png 512w, https:\/\/sinch.com\/wp-content\/uploads\/2025\/09\/SI-Blog-how-to-send-bulk-messages-on-whatsapp.rewrite-300x232.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><figcaption class=\"wp-element-caption\"><em>Creating a WhatsApp message template in Sinch Engage, with a live preview of how it lands on the customer&rsquo;s phone.<\/em><\/figcaption><\/figure>\n\n<h3 class=\"wp-block-heading\">4.

Launch your campaign<\/h3>\n\n<p class=\"wp-block-paragraph\">Upload or sync your segment, map your personalization fields, pick a send time that matches when your audience is actually on their phones, and send. A no-code platform like <a href=\"https:\/\/sinch.com\/fr\/engage\/canaux\/whatsapp\/\">Sinch Engage<\/a> handles this from a dashboard; developer teams can drive the same sends programmatically through Sinch&rsquo;s <a href=\"https:\/\/sinch.com\/apis\/messaging\/whatsapp\/\">Conversation API<\/a>. Start smaller than your maximum \u2013 a well-received first send to your best segment builds the quality signals that raise your limits.<\/p>\n\n<h3 class=\"wp-block-heading\">6. Measure, reply, and iterate<\/h3>\n\n<p class=\"wp-block-paragraph\">Watch delivery rate, read rate, clicks, and \u2013 most telling on WhatsApp \u2013 replies. Then act on what you see: a template with weak reads needs a better hook; a segment with high blocks needs less frequency or more relevance. And remember that bulk messaging on WhatsApp opens conversations. <strong>Have your team or a chatbot ready to answer within the customer service window<\/strong> \u2013 replies are the point of this channel, not a side effect.<\/p>\n\n<p class=\"wp-block-paragraph\">Brazilian retail rewards platform Familh\u00e3o shows what that looks like: by moving its subscription renewals into WhatsApp with Sinch, it lifted <a href=\"https:\/\/sinch.com\/customer-stories\/familhao\/\">renewal rates by 23 points<\/a>.<\/p>\n\n<h2 class=\"wp-block-heading\">What does bulk messaging on WhatsApp cost?<\/h2>\n\n<p class=\"wp-block-paragraph\">Since July 1, 2025, WhatsApp <a href=\"https:\/\/sinch.com\/fr\/blog\/whatsapp-business-tarification\/\">charges per delivered template message<\/a> rather than per 24-hour conversation. In simple terms:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Marketing templates<\/strong> are the premium category, priced per delivered message by destination country.<\/li>\n\n\n\n<li><strong>Utility and authentication templates<\/strong> cost meaningfully less \u2013 and utility templates delivered inside an open customer service window are free from Meta&rsquo;s side today.<\/li>\n\n\n\n<li><strong>Replies within the 24-hour customer service window<\/strong> are free-form and carry no Meta template fee.<\/li>\n\n\n\n<li><strong>One dated change to budget for:<\/strong> starting October 1, 2026, Meta begins charging for outbound messages sent during the customer service window \u2013 plan for it if your program leans on free service-window replies.<\/li>\n\n\n\n<li>On top of Meta&rsquo;s rates, your BSP&rsquo;s platform or per-message fees apply.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">So a 10,000-recipient campaign&rsquo;s cost depends on template category and destination country \u2013 budget from those two variables, not from a flat per-message guess. For current rates and worked examples, see our full <a href=\"https:\/\/sinch.com\/fr\/blog\/whatsapp-business-tarification\/\">WhatsApp pricing guide<\/a>.<\/p>\n\n<h2 class=\"wp-block-heading\">Bulk messaging best practices that protect your account<\/h2>\n\n<p class=\"wp-block-paragraph\">The mechanics get you sending; these habits keep you sending.<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Lead with value, not volume:<\/strong> Every message should solve a problem, save money, or genuinely inform.<\/li>\n\n\n\n<li><strong>Personalize past the first name:<\/strong> Use purchase and browsing data to make content feel individually chosen.<\/li>\n\n\n\n<li><strong>Mind your frequency:<\/strong> A few valuable messages a month beats a weekly drumbeat. Watch block rates as your early-warning signal.<\/li>\n\n\n\n<li><strong>Use rich media with intent:<\/strong> Images, short videos, and documents lift engagement when they add information, not decoration.<\/li>\n\n\n\n<li><strong>Test, then scale:<\/strong> Try two template variants on a small segment, and roll the winner out to the rest.<\/li>\n\n\n\n<li><strong>Keep an exit door open:<\/strong> Make opting out effortless and honor it instantly.
