Overview
🚀 Overview:
The Bulk LOI Sender Google Sheets™ add-on turns your spreadsheet into a reliable LOI mail-merge system. 

Generate professional and personalized letters of intent from a Google Doc™ template, attach each as a unique PDF, and send them via Gmail™, all in safe, quota-aware batches. Save yourself hours of work and stop copying, pasting, and attaching one-by-one; create, preview, and send at scale in minutes. 

Convert your leads with ease and make professional LOI outreach a repeatable, 5-minute task instead of an all-day chore!

👨‍💻 Who It's For:
Perfect for sales, partnerships, real estate, M&A, recruiting—anyone who needs to send many professional LOIs or emails with unique PDF attachments fast without leaving Sheets™.

🧪 Key Features: 
    ✔️Save hours of manual work (Template → Personalized LOIs → Email in one flow)
    ✔️Auto-PDF from Google Docs™ or send as plain text
    ✔️Safe batching & credit awareness (respects Gmail™ daily limits)
    ✔️Test sends to your inbox before going live
    ✔️Queue management: pause, resume, retry, clear sent
    ✔️Up to 26 merge fields: map columns to placeholders
    ✔️Status tracking (queued/processing/sent/failed) right from Sheets
    ✔️Attachment controls: include PDF or use Doc body as email text

⭐ How It Works:
1. Import or paste your leads (or upload CSV) into Sheets™
2. Select a Google Doc™ LOI template with merge placeholders (e.g., {{Company}})
3. Generate & send: review test emails, then batch-send with quota-aware controls
