Description
If your inbox feels like a second job — sorting what's urgent from what's not, drafting the same kind of reply over and over, juggling meeting requests — Stamp is built to be the assistant that handles the repetitive parts for you. It learns your writing style and personal context, then drafts replies that sound like you wrote them, flags what actually needs your attention, and can schedule calendar events on its own.
Technically, Stamp automatically generates email replies matched to your personal voice, prioritizes and categorizes incoming email with AI, manages calendar scheduling, builds long-term memory for personalization over time, and includes a mobile app with a voice mode plus bulk email drafting and web search integration for grounding its replies in current information. It supports multiple email providers and up to 2-5 connected accounts depending on plan. Pricing is a free 30-day trial, then Personal at $20/month, Business at $50/month (5 email accounts, 500 monthly enrichments), and custom Enterprise pricing, with a 20% discount for annual billing.
💬 Our review
The short version: Stamp is a solid pick if drafting replies and triaging your inbox is the specific time-sink you want automated — the personal-voice matching is the feature that actually differentiates it from a generic AI email assistant.
Against Superhuman, which is primarily a fast, polished email client with some AI features layered on, Stamp is built AI-first around drafting and prioritization rather than speed of navigation — different core value proposition. Against SaneBox, which focuses on filtering and folder-sorting without generating replies for you, Stamp goes further by actually writing drafts in your voice, which is more useful but also requires more trust that it won't misfire on a sensitive email. At $20-50/month it's a real recurring cost for what's ultimately a productivity nice-to-have, and personalized-voice email drafting is a category where quality varies a lot in practice — the free 30-day trial is worth using fully before committing. Pick Stamp if inbox triage and reply-drafting are your actual bottleneck, not just meeting scheduling, which cheaper single-purpose tools handle too.
