What are the best alternatives to Stamp?

Who should avoid Stamp?

Stamp is not for users wanting a traditional email client with no AI, those uncomfortable with AI reading their emails, or enterprise teams needing advanced compliance or admin controls. If you prefer manual inbox management, skip Stamp.

What are the main limitations of Stamp?

Key limitations include limited integrations (no mention of Slack or CRM), no offline mode, and potential privacy concerns as AI reads your emails. The free trial is only 30 days, and paid tiers may get pricey for heavy users.

What integrations does Stamp support?

Stamp supports major email providers like Gmail, Outlook, and Yahoo. It also integrates with your calendar for invite management. No native integrations with Slack, Notion, or CRMs are mentioned, so you may need to rely on web search for cross-platform tasks.

Is Stamp easy to set up and learn?

Stamp is designed to be user-friendly. Setup involves connecting your email account and training the AI by reviewing a few sample replies. Learning curve is low for daily use, but mastering AI Labels and agentic chat may take a few days.

Is Stamp good for small teams?

Yes, Stamp offers a Business tier suitable for small teams. It provides shared inbox intelligence, AI Labels for collaborative filtering, and agentic chat for delegated tasks. However, it lacks advanced admin controls needed for larger enterprises.

Does Stamp work with multiple email accounts?

Yes, Stamp supports multiple email providers including Gmail, Outlook, and Yahoo. You can connect several accounts to manage all emails from one interface. The free trial may have account limits, but paid tiers likely support multiple accounts.

Can Stamp draft replies automatically?

Yes, Stamp automatically drafts replies based on your writing style and context. It uses long-term memory to mimic your tone and can also send replies with one click in Stamp Mode. You can review and edit drafts before sending.

Is Stamp free to use forever?

No, Stamp is not free forever. It offers a 30-day free trial for new users. After that, you must choose a paid plan (Hobby, Personal, Business) to continue. There is no permanently free tier beyond the trial.

About Stamp

FreemiumIntermediateNo APIWeb · Mobile

Stamp is an AI-powered email and calendar assistant that learns your writing style, preferences, and workflows to handle your inbox on autopilot. It automatically drafts replies, prioritizes emails, categorizes them with custom AI Labels, summarizes threads, and extracts todos. Stamp can also schedule calendar events, search the web, and perform any action in your inbox via a chat Agent. Designed for busy professionals and small teams, Stamp aims to save hours daily by reducing decision load and completing work instead of merely suggesting words. The key differentiator is its learning capability: Stamp builds long-term memories about you and your contacts after each interaction, uses AI Labels to categorize email types and specify actions, and searches through your inbox and calendar for full context. This enables it to generate replies that sound exactly like you and handle tasks proactively. A dedicated mobile app with voice mode allows delegation on the go. Stamp supports major email providers, offers a free 30-day trial, and has three paid tiers (Hobby, Personal, Business) with varying usage limits. Its features are designed for doers who want to take control of their inbox and day, not just another email client with basic automation. Stamp competes directly with tools like Superhuman and Shortwave but focuses on proactive AI delegation rather than just speed. Its memory system and Stamp Mode are unique, though heavy users may hit caps on lower tiers.

Behind the Verdict

Stamp stands out in the crowded email assistant space because it doesn't just suggest replies—it drafts them in your voice and lets you approve with a single click (Stamp Mode). The memory system is the real star: it builds a profile of your preferences over time, making each reply more accurate. For professionals who get 100+ emails a day, this can cut inbox time by half. The mobile app with voice mode is a nice bonus for on-the-go triage. Where it falls short is for power users who need to connect more than 5 email accounts (Business tier caps at 5) or for teams needing advanced compliance. The AI can also occasionally misinterpret nuance, requiring manual edits. Compared to Superhuman, which focuses on speed and keyboard shortcuts, Stamp is more about delegation—you let the AI do the work, then approve. It's less suited for minimalists who prefer total control. We'd recommend Stamp for anyone overwhelmed by email volume who values personalization and proactive assistance. The 30-day free trial is risk-free to test its impact. Just be aware that the Hobby tier is very limited, so budget for Personal or Business if you're serious.
