VERDICT

Should I use MySigMail Card?

Self-hostable drag-and-drop editor built for email: 78 blocks, clean HTML and editable JSON export, AGPL-3.0. No account, no cloud. - card.mysigmail.com

Worth it. Buy if you want a free, self-hostable email template and signature builder with clean HTML export and no vendor lock-in. Skip it if you need company-wide signature enforcement or vendor support — CodeTwo or Xink fit better.

Confidence

Medium. Based on ~20 public sources; only 4 independent reviews found, so satisfaction claims rest on a thin base.
