Why is SelfMailKit better than Sendy for self-hosting?

SelfMailKit uses modern serverless architecture that auto-scales and requires zero maintenance, while Sendy requires manual server management and is prone to crashes under load. SelfMailKit also includes native inbox functionality and modern development practices.

How difficult is it to migrate from Sendy to SelfMailKit?

Migration is straightforward! You can export your contact lists from Sendy and import them into SelfMailKit via CSV. Our one-command deployment makes setup much easier than Sendy's manual server configuration.

What about the cost difference between SelfMailKit and Sendy?

While Sendy has a one-time license fee, you need to factor in server costs, maintenance, and potential downtime. SelfMailKit's pay-per-use model with AWS infrastructure often results in lower total costs and better reliability.

Does SelfMailKit support the same features as Sendy?

SelfMailKit supports all core email features that Sendy offers, plus many modern features like native inbox, advanced analytics, automatic scaling, and better security. You get more functionality with less maintenance.

Can I customize SelfMailKit like I can with Sendy?

Yes! SelfMailKit provides full source code access, allowing complete customization. The modern TypeScript/React codebase is much easier to modify than Sendy's PHP code, and you get better development tools and documentation.
