Mailbutler is a browser and app extension that adds features to Apple Mail, Gmail, and Outlook inboxes, including email tracking, mail merge, shared inbox collaboration, and signature marketing. It is aimed at individuals and teams who want to enhance their existing email client rather than switch to a new one. The product offers a free trial and tiered paid plans for additional features.
