Real-time monitoring

Track delivery rates, bounces, and complaints. Automatic sending pauses when thresholds are exceeded.

Smart rate limiting

Sequences that run on autopilot

Design multi-step sequences with email and wait steps. Personalize with template variables, set send windows by timezone, and let the engine handle the rest.

  • Automatic stop on reply, bounce, or unsubscribe
  • Per-step open and reply tracking
  • Send window and timezone targeting
  • Or just tell AI what you want to send

Stay out of spam. Automatically.

We verify your sending setup before the first email goes out. If bounce rates spike or recipients complain, sending pauses itself. You focus on writing. We handle the infrastructure.

  • Guided DNS setup with one-click Cloudflare support
  • Sending stops automatically when bounce rates spike
  • Warm-up that adapts to how recipients engage
  • AI alerts when bounce rates need attention
