Our verdict

Mailpengu adds a button to Gmail that auto-fills a sales presentation with the recipient's name, company description, and logo, then tracks whenever someone clicks a link inside it. An invisible watermark helps guard against the presentation being reused without permission. New signups get 25 free credits, after which further use runs on Mailpengu's paid credit system, and its track record so far rests on a single rating.
