What MailMaestro does
MailMaestro drafts, replies to, and improves emails directly inside Gmail and Outlook via an add-in, with magic templates, an adjustable AI personality, meeting-scheduling help, and email/attachment summarization. Flowrite was acquired by Maestro Labs and folded into MailMaestro, which now serves the same job: quick AI-assisted email composition without switching clients.
What you get: AI compose/reply/improve, Magic templates, Adjustable AI personality, Email & attachment summarization, Smart meeting scheduling, AI Priority Inbox (Outlook), Team template sharing.
Typical jobs: ai email writing add-in for outlook; flowrite alternative 2026; summarize long email threads automatically; ai email templates for gmail.
Worth knowing: Formerly Flowrite, acquired by Maestro Labs and rebranded; free plan is capped at only 3 AI requests per week.
What users complain about: Notes 'so little social proof around it compared to more established tools' and questions 'what distinguishes Flowrite from a paid ChatGPT subscription,' also flagging missing A/B testing, follow-ups, and deliverability monitoring.

Pricing and plan limits
Verified August 2026| Plan | Monthly | Annual (per mo) | Limits |
|---|---|---|---|
| Free | Free | Free | 3 Compose/Reply/Improve requests per week, total |
| Professional | $15 | $12 | Individual user |
| Team | $15 | $12 | Per user, team features |
| Enterprise | not disclosed | n/a | Custom |
Where it wins
- Works as a lightweight add-in inside existing Gmail/Outlook rather than a new client
- Free tier gives real (if very limited) access to GPT-4o/Claude 3.5 drafting
- Meeting scheduling and email/attachment summarization bundled in on Professional
- 14-day full-feature trial before committing
- Absorbed Flowrite's writing engine, so the underlying tech is field-tested since 2021
Where it falls short
- Free tier is extremely limited, only 3 AI requests per week total
- Brand recognition reset after the Flowrite → MailMaestro rename, so it shows up less in comparisons
- Lacks cold-email campaign features like A/B testing, automated follow-ups, or deliverability monitoring
- Several features (AI Priority Inbox, Email Reminders, Teams sharing) are Outlook-only
- Reviewers question what differentiates it from 'a paid ChatGPT subscription' for the price
