Stamp

An AI email secretary that learns your style to draft, prioritize, and schedule.

66/100MonitorFree · from $20/moFreemium

Stamp is a solid choice if you want an AI that truly acts like a secretary, not just a summarizer. The learning features (Memories, AI Labels) make replies feel personal, and Stamp Mode is genuinely efficient. But power users should note the usage caps on lower tiers—10x on Personal, 25x on Business—which may throttle heavy usage. If you're overwhelmed by email and want a hands-off assistant, Stamp's 30-day trial is worth testing. For a more traditional client, consider Superhuman, which adds AI as an enhancement rather than a delegation layer.

Skip it if

Skip Stamp if you are a power user who sends or receives a high volume of email and cannot tolerate usage caps, or if you need advanced enterprise compliance features that aren't explicitly documented.

The 30-second take
Biggest gripe

On lower tiers (Personal at $20/mo), usage is capped at 10x, which may not be enough for heavy email users, forcing a jump to Business at $50/mo.

Price reality

Stamp's pricing suits individuals and small teams that want AI delegation; Personal at $20/mo is competitive with Superhuman's $30/mo, but cheaper alternatives like SaneBox offer simpler filtering. Business at $50/mo is a mid-tier option for teams, though larger enterprises may expect more controls.

About Stamp

FreemiumBeginner-friendlyNo APIWeb · Mobile

Stamp is an AI-powered email and calendar assistant that acts as a personal secretary, learning your preferences to draft replies, prioritize messages, and manage your schedule—all in your voice and with your context. It's built for busy professionals, startups, and small teams who want to spend less time on email and more on actual work. Unlike simple email summarizers, Stamp goes beyond suggestions: it drafts replies, categorizes emails with AI Labels, and can even schedule events and search the web via an agentic chat. Stamp learns your style through three key features. Memories automatically record details about you and your contacts after each interaction, giving Stamp long-term context. AI Labels let you define plain-English rules for how different email types should be handled, with automatic actions. Context Search scans your inbox and calendar to grasp your writing style and availability before drafting or scheduling. This trio powers the core experience: automatic reply drafting, priority categorization, and task extraction. A standout workflow is Stamp Mode, where you can blaze through your inbox by simply approving Stamp's drafted changes with one keystroke—no typing required. The mobile app extends this to on-the-go delegation, with Voice Mode for hands-free operation. Need to handle a batch of emails? Bulk draft replies from a single prompt, or use the Agent to perform tasks like scheduling meetings or finding contact details across past emails and the web. Stamp supports existing email accounts with major providers, and offers a 30-day free trial. Pricing is tiered: a free plan, Personal at $20/month, Business at $50/month, and Enterprise with custom pricing for larger teams. Compared to premium email clients like Superhuman that add AI features, Stamp is an AI-first assistant that acts on your behalf rather than just enhancing a client. If you want an AI that learns you and takes action, not just a better inbox, Stamp fits the bill.

Behind the Verdict

Stamp is positioned as an AI-first email assistant, not just a client with AI features. Its core differentiator is the learning loop: Memories, AI Labels, and Context Search work together to make replies sound like you and actions match your workflows. Stamp Mode is a genuine time-saver, letting you approve drafts with a single keystroke, which is faster than typing even a short reply. The mobile app with Voice Mode extends this to hands-free delegation, which is useful when you're away from your desk. However, the pricing caps on lower tiers (10x on Personal, 25x on Business) could throttle heavy users, and the higher tiers are a significant commitment at $50/month. For enterprises, the custom Enterprise tier offers on-prem deployments and white-glove onboarding, but specific compliance or audit features aren't documented. If you're a freelancer or small team that wants to delegate email busywork, Stamp's trial is worth a shot. But if you prefer a traditional email client with optional AI boosts, you might find the subscription model harder to justify. Also, consider that while Stamp supports major email providers, integration with niche providers may require the Enterprise tier.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • On lower tiers (Personal at $20/mo), usage is capped at 10x, which may not be enough for heavy email users, forcing a jump to Business at $50/mo.
  • Profile enrichments are limited to 50 per month on Personal and 500 per month on Business; exceeding these may incur extra costs or require a plan upgrade.
  • While the free tier exists, it has limited usage and basic AI features, so you'll likely need a paid plan for meaningful automation.
  • Support for any email provider is only available on the Enterprise tier, so if you use a niche provider, you'll need to pay for custom pricing.

Where the pricing makes sense

The company stage and team size where Stamp's pricing actually pencils out — and where peers do it cheaper.

Stamp's pricing suits individuals and small teams that want AI delegation; Personal at $20/mo is competitive with Superhuman's $30/mo, but cheaper alternatives like SaneBox offer simpler filtering. Business at $50/mo is a mid-tier option for teams, though larger enterprises may expect more controls.
