The format of the import file of email contacts

You can load a list of recipients from a file created by any table editor that supports the CSV format up to 20 MB.

The conditions for a CSV file should be like this.

• File format: CSV
• Separator: comma (,) or semicolon(;)
• Encoding: UTF-8 or Windows-1251
• Column headers: optional
• Maximum file size: 20 MB

If the field is named incorrectly, you must select it manually when uploading the file.

Individual fields in the header of the csv file are named with the prefix » custom_properties.»i.e.» custom_properties. KEY «, where KEY is the key of the individual field. (This excludes the intersection of the names with the standard fields).

If errors occur when uploading the file, try selecting a different encoding from the drop-down list.

Important! Ensure high deliverability and avoid account suspension

To maintain a high sender reputation and prevent your account from being blocked due to spam, it's crucial to validate your contact list before uploading.

Check the "Email" column for common errors:

📌 Typos in well-known email domains:

✖ lizst.com → ✅ list.com

✖ gmail.co → ✅ gmail.com

✖ homail.com → ✅ hotmail.com

…and similar mistakes.

💡 Use an email validation service to check your list before importing.
