Frequently Asked Questions

Spark has a free plan for individuals with basic smart inbox features. Spark Premium for teams starts at $4.99/user/month and adds email delegation, team templates, and advanced integrations. Superhuman starts at $30/user/month with no free tier.
Is Superhuman or Spark better for small businesses?
For small businesses, Superhuman tends to be the better starting point thanks to more accessible pricing and a simpler onboarding process. Spark is often the stronger choice for mid-size or enterprise teams that need deeper customization. Both offer free trials, so test each with your actual workflow before committing.
Can I migrate from Superhuman to Spark?
Yes, most users can switch within a few days to two weeks depending on data volume. Spark provides import tools and migration documentation to help with the transition. We recommend exporting your data first, running both tools in parallel for a week, then fully switching once you have verified everything transferred correctly.

Editor's Take
I've used both Superhuman and Spark extensively. Superhuman feels more polished out of the box, but Spark surprised me with how much it's improved recently. If I had to pick one today, I'd look at what my team is already using — switching costs are real.
