About Outlook Bulk Mail Merge
╔════════════════════════════════════════════════════════════╗
📧 OUTLOOK BULK MAIL MERGE
✨ Send many emails at once — each one personal — from YOUR Outlook
╚════════════════════════════════════════════════════════════╝
👋 WHAT IS THIS?
Got a list of people in Excel or CSV? Want to email them all — but each
email should feel personal, with their name and details filled in for you?
🎯 Outlook Bulk Mail Merge does exactly that!
You write ONE email template. The extension reads your spreadsheet and
sends a unique email to each person — through YOUR own Outlook account.
✅ No extra email server
✅ No complicated setup
✅ Just log in → upload → write → send
The best bulk mail merge app for Outlook.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🚀 HOW IT WORKS — 4 EASY STEPS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔐 1. LOG IN
Sign in with your Outlook or Microsoft 365 account.
📊 2. LOAD YOUR CONTACTS
Drop an Excel (.xlsx, .xls) or CSV file.
📎 Needs an email column — we find it for you!
🏷️ Click merge-field chips to insert placeholders like {firstName}
✍️ 3. WRITE YOUR MESSAGE
One subject + one body for everyone. Use {placeholders} for personal bits.
📌 Example:
Subject → Hello {firstName}
Body → Hi {firstName}, hope you're doing well!
👤 John gets → "Hello John"
👤 Jane gets → "Hello Jane"
📤 4. SEND
Hit Send emails. Each person gets their own message from your mailbox!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📎 ATTACHMENTS (OPTIONAL)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Need a different file for each person? No problem! 📁
1️⃣ Pick a folder of files on your computer
2️⃣ Choose how to match files to people:
📋 Match by column
Your spreadsheet tells us which file each person gets.
🔤 Match by filename
Find files by name — like {email}.pdf for each person,
or newsletter.pdf for the same file to everyone.
🔢 Match by folder order
1st person → 1st file, 2nd person → 2nd file, and so on.
💡 Attachments are totally optional — skip them if you don't need any.
⚠️ Each file max 3 MB · Re-select folder each time you open the popup
(Chrome security rule — not our choice! 😅)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🛠️ BUILT-IN TOOLS YOU'LL LOVE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🧪 DRY RUN
Run the full batch WITHOUT sending. Perfect before a big send!
⏱️ THROTTLE
Pause between emails (e.g. 1.5 sec) so you don't hit rate limits.
📥 CREATE LOG
Download a CSV after sending. Pick what to include:
✅ successes · ⚠️ sent without attachment · ❌ failures
🌙 DARK MODE
Easy on the eyes, day or night.
💾 SAVED SETTINGS
Templates and preferences stay saved in the extension.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔒 YOUR DATA & PRIVACY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📬 Emails send through Microsoft Graph from YOUR signed-in account.
They show up in your Sent folder like normal Outlook mail.
💻 Your spreadsheet & files stay on YOUR computer — read locally in
the browser to build each email.
🚫 We do NOT run a mail server. We do NOT store your contact lists.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🎯 PERFECT FOR
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🎓 Teachers & coaches emailing a group
🏢 Small business outreach & follow-ups
📋 Anyone with a spreadsheet who hates complicated mail-merge tools
📧 Outlook users who want to stay in their own inbox
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📊 SPREADSHEET EXAMPLE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Column named "email" is auto-detected. Every other column = a placeholder!
┌────────────────────┬───────────┬──────────┐
│ email │ firstName │ company │
├────────────────────┼───────────┼──────────┤
│ john@example.com │ John │ Acme Co │
│ jane@example.com │ Jane │ Beta Inc │
└────────────────────┴───────────┴──────────┘
Use {firstName}, {company}, {email} — any column in {curly braces}! ✨
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
💡 GOOD TO KNOW
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
☑️ You need a Microsoft / Outlook account that can send mail
☑️ Follow your organization's email & anti-spam rules
☑️ Try Dry run + a small test list before going big 🎯
☑️ Missing attachment? Send without it or skip that person — you choose
