404 Emails

Import contacts from a CSV file

Bring your list from a spreadsheet or another email tool.

Export your contacts from your current tool or spreadsheet as a CSV file (up to 5 MB and 10,000 rows per file), then go to Contacts and start an import.

  1. Upload the CSV file.
  2. Match your columns to 404 Emails fields: email address (required), first and last name, and tags if you have them.
  3. Choose which subscription the contacts join, and confirm where their permission to be emailed came from. Imported contacts get a consent record based on what you confirm here, so be accurate.
  4. Check the preview: how many will be added, updated, skipped as invalid or duplicates, and how many are already blocked.
  5. Start the import. Larger files take a minute or two.

Only import people who agreed to receive your emails. Addresses that previously unsubscribed, bounced or complained stay blocked, even if they're in the file.
