What is SuperMailer?
SuperMailer is a Windows desktop application for preparing and sending personalized newsletters and mail-merge email. Compose HTML messages in its WYSIWYG editor or use plain text, then insert recipient fields for names and other details. Recipient lists, message text and attachments are organized into projects stored on your computer.
You can import recipients from CSV files, Excel, Outlook or SQL databases. Messages can be sent through your email provider’s SMTP server, with other publisher-documented sending routes available. The application supports personalized attachments as well as standard file attachments.
The free version supports up to 100 recipients; larger lists require a paid license. The send-through-Outlook option needs classic Outlook because the new Outlook app does not expose the required COM automation interface. This entry links to the publisher’s 64-bit German/English Windows installer. The screenshot is a historical source-gallery view of the English message editor, not a verified capture of version 15.00.
