How to Mail Merge and Send Documents by Post

Mail merge lets you personalize and send the same document to many recipients at once. Whether you're using Microsoft Word, Google Docs, or a dedicated service, here's how to merge documents and send them by physical mail.

Option 1: Use Mailform's Bulk Mail Tool (Easiest)

Mailform supports bulk mailing with CSV-based address imports — perfect for mail merges. Upload your PDF documents and a CSV of recipient addresses, and Mailform prints and mails each piece individually.

1. Prepare your merged PDFs (one per recipient) or a single document to send to many addresses
2. Go to mailform.io and select Bulk Mail
3. Upload your PDF(s) and import your recipient list via CSV
4. Choose USPS First Class, Certified Mail, Priority, or FedEx Overnight
5. Submit — Mailform handles all printing and mailing

Option 2: Mail Merge with Microsoft Word

Word's built-in mail merge uses an Excel spreadsheet as a data source:

1. Create your data source in Excel (name, address columns, etc.)
2. In Word, go to Mailings > Start Mail Merge > Letters
3. Click Select Recipients > Use an Existing List and select your Excel file
4. Insert merge fields (e.g., «FirstName», «Address») into your document
5. Click Finish & Merge to generate individual letters
6. Export to PDF and upload to Mailform for physical mailing

Option 3: Mail Merge with Google Docs

Google Docs supports mail merge via add-ons like Yet Another Mail Merge (YAMM) or Autocrat. These pull data from Google Sheets to generate personalized documents. Once generated, export as PDFs and upload to Mailform to send by post.
