Smart Assistant by Mailbutler
An AI email assistant that drafts, summarizes, and perfects your messages in place
AI drafting and reply generation
Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.
Thread summarization
Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.
Grammar and tone correction
The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.
Smart Follow-ups
Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
Strengths & Pros
+Works inside Apple Mail, Gmail, and Outlook instead of forcing another app into your stack
+AI drafting, summarization, and grammar checks are combined with tracking and follow-up prioritization in one place
+Strong privacy posture: ISO/IEC 27001 certified, GDPR compliant, and servers located in Germany
+Free 14-day trial unlocks all features with no credit card required
+Teams can share templates, signatures, and inbox assignments with role-appropriate controls
Limitations
–Most genuinely useful AI features require a paid plan, and full automation sits on higher tiers
–Free tier is limited, so the free-forever Starter plan is best treated as a lite entry point
–Used for email drafting, email body text is transmitted to OpenAI (addresses are tokenized), which some compliance teams will want to review
–Feature depth varies slightly by client since it is an extension layered over three different email apps
