Feature-by-feature

Fastmail and Genspark are distinct tools serving different primary functions. Fastmail is a dedicated email and calendar hosting service focused on privacy, speed, and control. Its standout features include custom domain email, Masked Email for privacy, offline mode, and integrated calendars with multiple calendar support. It lacks AI-driven features like content generation or automation. Genspark, on the other hand, is an all-in-one AI workspace that goes beyond email. Its core capability is Sparkpage—synthesized, cited summaries from multiple web sources. Additionally, it offers deep research mode, AI-powered document/slide/sheet creation, AI Pods for podcast generation, Clip Genius for video editing, and AI Designer. The latest AI Workspace 6.0 introduces AI Employee for no-code internal tool creation and Super Agents for custom automation. Genspark integrates with Google Workspace, Canva, Figma, and Microsoft 365, whereas Fastmail integrates with password managers and calendar services. For a user needing reliable email and calendar, Fastmail is purpose-built. For someone who researches, creates content, and wants AI automation, Genspark provides a broader set of tools.

Pricing compared

Fastmail operates on a paid-only model. The Individual plan costs $20 per month and includes masked email, 10GB file storage, and all core features. No free tier is available, though a 30-day free trial is offered. Business plans add admin controls but pricing details aren't specified here. Genspark follows a freemium model with a free tier, but specific pricing for paid plans is not provided in the data. This makes Genspark more accessible for budget-conscious users who can start free and upgrade as needed. Fastmail’s pricing is straightforward but higher for users who only need basic email. However, its ads-free, privacy-focused service justifies the cost for those prioritizing data control. Genspark’s free tier may limit advanced features like AI Employee or custom Super Agents, but it offers a wide range of AI tools without upfront payment. For a small business needing professional email, Fastmail’s predictable cost is ideal. For a student or researcher wanting AI assistance, Genspark’s free entry point is attractive.
