The Plus plan costs $99/month but is more suited for growing businesses with higher email volume needs. Superhuman offers a free tier that provides essential features like real-time grammar checking and collaborative document creation. Its Pro plan at $12 per month adds unlimited paragraph rewrites and translations in 19 languages, while the Business plan at $33 per month includes advanced CRM integrations and data sync from platforms like Jira and GitHub.
For solo users on a tight budget, Mailgun's free tier is restrictive with only 50 emails/day available. The paid plans start at $12/month for basic functionality but can quickly become expensive as email volume increases. Superhuman’s free plan offers robust features that enhance writing quality and simplify daily tasks without the need for extensive setup or training. However, its Pro plan might be costly for solo users who do not require all business-oriented features.
