Bulk mailing is the process of sending the same or similar letter to multiple recipients at once. Instead of preparing each letter individually, you create one template and send it to everyone on your list.

You should use bulk mailing when you need to send letters to 3 or more people. Common use cases include:

• Holiday cards and greetings — Send season's greetings to friends and family
• Wedding or event invitations — Mail invitations to your entire guest list
• Business announcements — Notify clients or customers of changes, moves, or updates
• Thank you notes — Send appreciation letters after events or donations
• Newsletters and updates — Keep your community, club, or organization informed
• Rent notices and property management — Send notices to multiple tenants simultaneously
• Legal or official notices — Distribute required correspondence to multiple parties

Doing this the traditional way—printing, folding, addressing, and stamping each letter individually—takes hours. An online bulk mailing service completes the same task in minutes.

To send bulk mail in Canada, use an online mailing service like PostPal that handles printing and delivery for you. The process takes 4 simple steps:

Step 1: Enter Your Return Address

Start by entering your sender address. This appears as the return address on every envelope. You can also choose to skip the return address or use PostPal's office address if you prefer privacy.

Step 2: Add Your Recipients

Add everyone you want to send letters to using one of three methods:

• Upload a CSV file — Import a spreadsheet with all your addresses at once (fastest for large lists)
• Select from address lists — Choose recipients from lists you've saved in your PostPal dashboard
• Add manually — Enter addresses one by one directly in the form

Step 3: Write Your Letter Template

Compose your letter using the template editor. Insert personalization variables like {First Name} to customize each letter automatically. Every recipient receives a letter addressed specifically to them.

Step 4: Preview and Complete Your Order

Review how your letters will look, confirm the total cost with your bulk discount, and pay. PostPal prints, stuffs envelopes, applies postage, and mails all letters within 24 hours.

To upload multiple addresses, prepare a CSV (spreadsheet) file with your recipient data and import it into PostPal. Here's how:

Preparing Your CSV File

Create a spreadsheet with columns for each piece of address information. Your file should include:

• Full name (or separate first name and last name columns)
• Street address
• City
• Province or state
• Postal code or ZIP code
• Country (required for international addresses)

Save the file as a CSV. Most spreadsheet programs (Excel, Google Sheets, Numbers) can export to CSV format.

Uploading to PostPal

1. In the Recipients step, click the "Upload CSV" tab
2. Drag and drop your file or click to browse
3. PostPal will detect your columns and ask you to map them to the correct fields
4. Confirm the mapping and your recipients are imported instantly

Alternative: Use Address Lists

If you send mail regularly to the same groups, save them as address lists in your PostPal dashboard. When sending bulk mail, simply select which lists to include. This is ideal for:

• Annual holiday card lists
• Client contact lists
• Family address books
• Tenant or member directories

To personalize bulk letters, use template variables that automatically insert each recipient's information. Write your letter once, and PostPal customizes it for every person on your list.

Available Personalization Variables

Click any variable button in the template editor to insert it:

• {First Name} — Inserts the recipient's first name
• {Last Name} — Inserts the recipient's last name
• {Full Name} — Inserts the recipient's complete name
• {City} — Inserts the recipient's city

Example: Before and After

Your template:

Dear {First Name},

I hope this letter finds you well in {City}. I wanted to reach out to share some exciting news...

Warm regards

What Jane Smith in Toronto receives:

Dear Jane,

I hope this letter finds you well in Toronto. I wanted to reach out to share some exciting news...

Warm regards
