Bulk Messenger Marketing Blast

I need an experienced messenger-marketing specialist to execute a one-off text-blasting campaign that targets both my existing and potential customers. The goal is straightforward: deliver a high-impact marketing push through Facebook Messenger

Here’s what I already have in place:
• A cleaned, fully opted-in subscriber list exported in CSV.
• The exact copy for each message—no creative work required.
• A clear send schedule and desired segmentation tags.

What I need from you is the technical setup, scheduling, and flawless deployment of the blast, along with basic performance reporting after completion. I’m happy for you to work in ManyChat, Chatfuel, the official Messenger API, or another reputable tool—as long as it can handle bulk sends, automate compliance elements (unsubscribe, 24-hour rule), and give me delivery/open metrics.

Deliverables:
1. Import my list and verify opt-in compliance.
2. Configure the broadcast inside the chosen platform, including fallback content for users outside the 24-hour window.
3. Schedule and send the blast on the agreed date/time.
4. Provide a concise post-send report (sent, delivered, opened, clicks).

The campaign is a single blast, but if it goes smoothly there’s potential for ongoing work.
