There are four ways to bring your emails in. Pick whichever is easiest for you. Go to Lists, then click New list, and choose one:
1. Upload a CSV
Drag a CSV file onto the page, or click to browse for it. This is the most common way. We look at your file and figure out which column holds the email addresses automatically.
2. Paste rows
Copy your emails and paste them straight in — one email per line. You can also paste a CSV with headers if you have extra columns like names.
3. Link to a file
If your list lives at a web address, paste the link (a public web link to a CSV file). We will fetch it for you.
4. Import from a connected tool
If you use an email marketing tool like Mailchimp or Brevo, you can connect it once and then import an audience directly — no file needed. See the Integrations section to set this up.
Tip
Just want to test? Paste a few addresses. You are only charged for the addresses you actually check.
