Full review
Mailbutler is run by Mailbutler GmbH, Akazienstr. 3a, 10823 Berlin, registered at Berlin-Charlottenburg under HRB 166863 B. The impressum names Fabian Jäger as management, and the terms are issued by the same company.
The FAQ on the home page describes Mailbutler as an extension that adds email productivity tools to your Apple Mail, Gmail or Outlook inbox. It is not a standalone inbox app, so the mailbox stays with its current provider.
Tracking, follow-ups and templates in Mailbutler
The Starter plan includes basic email tracking that shows when emails were first opened and links first clicked, with real-time notifications. The solution list also names follow-up suggestions and per-recipient tracking.
Tailored sending covers message templates, mail merge, smart timing and an AI email assistant. Inbox organisation adds email assignments, live status indicators, private and shared notes, tasks and automations.
Mailbutler prices and trial
Mailbutler offers a free 14-day trial that includes all features and needs no credit card. Prices are shown in USD and EUR.
In euros, Starter is listed at 3 € per user per month on yearly billing, and Professional at 6 €, with VAT added on top. Monthly billing is 4 € and 8 €.
Mailbutler compared with Superhuman
Superhuman Mail charges $25 USD per member per month for Starter. Mailbutler is cheaper because it adds features to an inbox you already use, instead of replacing the client.
Superhuman offers its own keyboard-led inbox, so Mailbutler gives up the dedicated app experience.
Where it falls short
Mailbutler is an extension, not a mail client, so you still depend on Apple Mail, Gmail or Outlook, which may belong to a US company. The site's own pages describe features in marketing terms and do not state a per-feature comparison with Superhuman. Open and click tracking relies on tracking pixels, which some recipients block. See Mailtrack for a similar add-on from Spain.
Who Mailbutler fits
Sales teams and professionals on Apple Mail, Gmail or Outlook who want tracking, templates and follow-up reminders from a German vendor without changing their mail client.
