I have an existing WhatsApp group and need roughly 800 new members added as quickly and smoothly as the platform allows. I will supply the phone numbers in whichever format you prefer—CSV, Excel or straight text—once we agree on the workflow. Your task is to handle the entire onboarding process, from importing the contacts to confirming they appear in the group. You should already be familiar with current WhatsApp limits on direct additions versus invite-link sharing and be able to advise the most efficient approach so we avoid any account or group restrictions. Final acceptance is simple: the group shows the additional 800 members (or as many as WhatsApp permits if we hit hard caps) and I receive a brief report confirming the total added and any numbers that could not be joined. If you’ve done high-volume WhatsApp management before, especially with the latest app versions, let me know—speed and reliability are what matter most here.
