Bulk WhatsApp Blast & Tracking

I have a list of roughly 2 000 WhatsApp numbers and a single outreach I need pushed out in one wave:

• a short, pre-written text
• the same video appended to that text

No images need personalisation and there is nothing else to customise per contact, but I do want reliable analytics. After the campaign I must be able to see who actually received the message and who opened it (standard WhatsApp delivery & read ticks or an equivalent exportable report).

You may use any compliant solution or API you’re comfortable with—as long as accounts stay safe from spam bans and the send-out really reaches the full list. I will supply:

• the contact spreadsheet (CSV or Excel)
• the final text copy
• the video file (MP4, <15 MB)

Deliverables I expect:
1. Complete broadcast to all 2 000 numbers.
2. Post-send report showing delivery and read status for each contact.
3. Brief note on the method/tool used so I can repeat future campaigns.

If you’ve run large WhatsApp blasts before and can guarantee accurate tracking, let’s get this scheduled.
