Import Subscribers

Add subscribers in bulk from a CSV

Overview

Subscribers are the people who will receive your newsletters via email. You can import subscribers and assign them to one or more lists. You can import subscribers:

  • in bulk using a CSV file
  • one at a time

1. Open the Subscribers Panel

  1. From the Dashboard, click Subscribers in the left-hand menu.
  1. Click Add Subscribers to begin the import process.
  1. Choose to Add multiple subscribers to import a CSV or Add a single subscriber to add subscribers one at a time.

⚠️

Tips

  • Always clean your CSV before uploading (remove duplicates, ensure emails are valid).
  • Add subscribers to specific lists to make sending targeted newsletters easier.

2. Choose Subscriber Lists

  • Select one or more lists from the List menu.
  • If you haven’t created a list yet, click New List, give it a name, and select it.
📌 Lists help you segment your audience (e.g., Early Childhood, Sports Program, Volunteers).

3. Upload Your CSV File

  • Click Import Subscribers.
  • Select the CSV file from your computer.
  • Your CSV should include the following columns:
    • First Name
    • Last Name
    • Email Address

Each row in the CSV represents one subscriber.


4. Preview and Map Fields

Once uploaded, Bundlebird will show you a preview of your file:

  • Check that the columns look correct.
  • Click Next to map the fields.
    • Confirm which columns in your CSV match:
      • Email Address
      • First Name
      • Last Name

Bundlebird will try to auto-detect these, but you can manually adjust if needed.


5. Review and Fix Errors (If Any)

After mapping, you’ll see a data verification screen:

  • Bundlebird will flag:
    • Missing email addresses
    • Invalid formats
    • Duplicates

You must fix all errors before continuing. You can:

  • Edit your CSV file and re-upload it, or
  • Remove problematic rows from the import.

6. Final Import and Confirmation

Once verified:

  1. Click Submit to begin processing your data.
  1. Don’t close your browser — this may take a few minutes for large lists.
  1. When processing completes, you’ll return to the Add Subscribers screen.

Bundlebird will show:

  • The number of new subscribers ready to be added.
  • Any duplicates that were skipped.
  1. Click Add Subscribers to finish the process. Your contacts will now be saved and assigned to the selected list(s).

Add a single subscriber

  1. The Add subscribers dialogue defaults to Add multiple subscribers. Choose Add a single subscriber from the bottom of the dialogue.
  1. Fill in the subscribers email. Note: subscriber first name and last name are optional.
  1. Add the subscriber to one or more lists with the Add subscriber to lists drop down.
  1. Click Add subscriber.
