## Keplars vs Resend

A practical comparison for product teams. Have a side-by-side look at setup effort, pricing flexibility, deliverability model, and developer experience when sending transactional and product emails.

### Why teams move from Resend to Keplars?

- **Great DX. Zero Setup Pain.**  
  Keplars is built for developers who want to move quickly without setup friction. Connect via OAuth, API, SMTP, or webhooks and start sending in minutes, with clean defaults, clear logs, and predictable behavior that feels natural in real production workflows.

- **Built to stay out of spam**  
  Keplars is designed for product emails that must reach the inbox. By separating transactional traffic from marketing flows and enforcing clean sending behavior, Keplars achieves 99.99% inbox placement with an average spam rate of ~0.01%.

- **Pricing that adapts as you grow**  
  Instead of forcing teams into rigid tiers, Keplars uses dynamic, component-based pricing. You pay for what you actually use, whether that's more emails, domains, webhooks, or team members.
