Our take

Beginner-friendly · Email plan $12/month

MailMaestro is where Flowrite went: Maestro Labs bought it. It's an add-in for Outlook and Gmail that drafts, rewrites and summarizes, for $12 a month.

Also look at Microsoft Copilot and Grammarly.

The quick breakdown

Good for: Outlook users at work who want help writing and summarizing without switching apps.
Not great for: People happy with Copilot already included in Microsoft 365.
Watch out: $12 a month per seat after the trial. If you already pay for Microsoft 365 Personal, Copilot covers most of the same ground.
What people say: Few independent reviews yet. Most mentions come from the maker.

Based on Maestro Labs pricing, Flowrite is now MailMaestro, plus the tool's own site. Not much independent feedback exists yet. Checked Oct 15, 2026. Prices change, so confirm before you pay.
