Why teams switch from Mailchimp

  • Transactional + marketing on one stack
  • Self-hostable for teams that outgrow SaaS pricing
  • Clean, modern UI without Mailchimp's upsell maze

Developer APIs

Send campaigns and transactionals programmatically.

No platform tax

Transparent pricing without constant upgrade prompts.

Open source

Extend, fork, or self-host instead of waiting on feature requests.

Honest trade-offs

Choose Reloop when…

  • You want source access and a self-host exit ramp.
