Introducing Rewarmly: privacy-first email warmup for Resend

Rewarmly is an email warmup tool designed specifically for Resend teams. We're early, we're shipping fast, and we're building around a simple idea: warmup should feel like strategy, not setup docs.

What we're optimizing for

• Deliberate pacing so sending volume ramps predictably.
• Clear milestones so teams know what "healthy" looks like day to day.
• Deliverability guardrails that reduce risk when signals change.
• Privacy-first defaults so we don't store what we don't need.

Privacy is the default

Rewarmly avoids storing personal data we don't need. Contact-level warmup state lives in Resend. We focus on orchestration and high-level configuration so you can move quickly without creating new data exposure.

What you'll see in the product

• Plain-language stages: start, ramp, stabilize
• Clear daily targets and predictable progression
• Template variations to keep activity natural
• Safety checks to avoid spikes and reputation shocks

We're early - and that's an advantage

If you're warming a domain now, you get a tool that's focused, opinionated, and built around what sending teams actually need. We're not trying to be everything; we're trying to be the warmup engine you trust.

Get started when you're ready.
