The ConvertKit alternative built for modern teams
ConvertKit is great for bloggers but has no transactional email API. Sendbound handles newsletters and app emails in one platform, with usage-based pricing up to 88% cheaper at scale.
Built for a better email experience
ConvertKit is for creators, Sendbound is for apps
ConvertKit (now Kit) is fantastic for bloggers and course creators. It is not built for SaaS apps sending transactional emails, password resets, or API-triggered notifications.
No transactional email support
ConvertKit does not provide a true transactional email API. If you build an app, you'll still need another provider to handle your application's core emails.
Subscriber-based pricing
ConvertKit charges based on your subscriber count. Sendbound's usage-based pricing is fairer for SaaS applications that may have many users but send lower volumes of targeted emails.
Code-first templates
ConvertKit offers basic text editors. Sendbound lets developers build sophisticated, branded templates using React Email, kept in version control.

Developers who made the switch
We loved ConvertKit for our marketing, but trying to send app notifications through it was a disaster. Sendbound handles both perfectly with an API our devs love.
Being able to keep our email templates in our Git repository alongside our frontend code is a game-changer. Sendbound + React Email is the future.
