It is the highest-risk thing an unofficial WhatsApp integration does, because it is exactly the shape of unsolicited marketing, and Wapito meters it separately from ordinary replies with its own hourly ceiling.","The distinction the abuse systems care about is not how many messages you send but how many strangers you message. Fifty replies inside live conversations look like a busy support desk; fifty first-contact messages from a young number look like a list being worked. Wapito treats a recipient as cold when there is no record of inbound contact and no prior relationship on the channel, and it applies an hourly ceiling that starts very low on a new number and rises with the warm-up ladder. Sends refused by the guard are not counted against you, so the ceiling cannot be gamed by retrying. The way to stay comfortably inside it is not to tune the number but to change the flow: get the first message to come from the customer, by putting a click-to-chat link on your site, a QR on a receipt, or a keyword in an email. An inbound-first design is both safer and more effective, because the people who write to you are the people who wanted to hear from you.",{"example":7,"field":8},"{\"cold_sends_hour\": 8, \"cold_send_cap\": 10, \"warmup_day\": 1}","cold_sends_hour","On the official platform the same idea is enforced commercially and technically: outside the customer service window a business can only send pre-approved templates, and each one is charged.","What is a cold send on WhatsApp?",{"features":12,"hub":25,"operations":26,"terms":36},[13,16,19,22],{"title":14,"url":15},"Send Group Message","\u002Fwhatsapp-api\u002Fsend-group-message\u002F",{"title":17,"url":18},"Group Events","\u002Fwhatsapp-api\u002Fgroup-events\u002F",{"title":20,"url":21},"Post to Channel","\u002Fwhatsapp-api\u002Fpost-to-channel\u002F",{"title":23,"url":24},"Send Without Template","\u002Fwhatsapp-api\u002Fsend-message-without-template\u002F","\u002Fglossary\u002F",[27,30,33],{"title":28,"url":29},"POST \u002Fmessages\u002Ftext","\u002Fdocs\u002Fapi\u002Fmessages\u002Fsend-text\u002F",{"title":31,"url":32},"GET \u002Fchannel\u002Flimits","\u002Fdocs\u002Fapi\u002Fchannel\u002Fget-channel-limits\u002F",{"title":34,"url":35},"POST \u002Fcontacts\u002Fcheck","\u002Fdocs\u002Fapi\u002Fcontacts\u002Fcheck-contacts\u002F",[37,40,43],{"title":38,"url":39},"Warm-up","\u002Fglossary\u002Fwarm-up\u002F",{"title":41,"url":42},"Timelock","\u002Fglossary\u002Ftimelock\u002F",{"title":44,"url":45},"Cloud API","\u002Fglossary\u002Fcloud-api\u002F",[47,55,62],{"availability":48,"ban_risk":49,"method":50,"operationId":51,"path":52,"summary":53,"tag":54,"url":29},"ga","medium","POST","sendText","\u002Fmessages\u002Ftext","Send a text message","messages",{"availability":48,"ban_risk":56,"method":57,"operationId":58,"path":59,"summary":60,"tag":61,"url":32},"low","GET","getChannelLimits","\u002Fchannel\u002Flimits","Get quotas, warm-up and timelock state","channel",{"availability":48,"ban_risk":63,"method":50,"operationId":64,"path":65,"summary":66,"tag":67,"url":35},"high","checkContacts","\u002Fcontacts\u002Fcheck","Check numbers for WhatsApp registration","contacts",{"breadcrumb":69,"canonical":78,"description":79,"h1":10,"lastmod":80,"title":81},[70,73,75],{"name":71,"url":72},"Home","\u002F",{"name":74,"url":25},"Glossary",{"name":76,"url":77},"Cold send","\u002Fglossary\u002Fcold-send\u002F","https:\u002F\u002Fwapito.com\u002Fglossary\u002Fcold-send\u002F","A cold send is a first message to somebody who has never written to your number.
