Importing Recipients2 min read

Paste emails directly into CMass

The fastest way to add recipients: paste a list of emails — one per line — with optional first name and last name.

The Paste import method is the quickest way to add a small list of recipients. It's perfect for lists under 100 contacts or for quick one-off campaigns where you don't have a spreadsheet ready.

Format

Each line is one recipient. Email only is the minimum. You can optionally include first name and last name, separated by commas:

  • ▸Email only: john@acme.com
  • ▸With first name: john@acme.com, John
  • ▸With first and last name: john@acme.com, John, Smith
💡 Names are optional but recommended — they unlock {first_name} and {last_name} merge tags and improve AI personalization quality.

How to use it

  1. 1Open CMass from the compose window
  2. 2Go to the Recipients tab
  3. 3Make sure the '✏️ Paste' source tab is selected
  4. 4Paste your list into the text area
  5. 5Click 'Add to list'
CMass Recipients tab with the Paste import method selected
Paste email addresses one per line — with optional name fields.

CMass deduplicates automatically — if you paste the same email address twice, it only adds it once.

Tips

  • ▸Separate multiple recipients with new lines or semicolons
  • ▸You can paste from Excel, Google Sheets, Notion, or anywhere — CMass reads plain text
  • ▸Mix formats freely — some lines can have names, others can just be email addresses
  • ▸Emails that don't contain '@' are silently skipped

Try it in Gmail — free

50 emails/day on the free plan. No credit card needed.
