How to choose
Start with Upstream when daily inbox triage and reply drafting are the main pain points. Choose Migma AI or Turumail for full-sequence automation and continuous optimization. Add Mailwarm or Peeker if sender reputation and self-repair matter most. Watch for agents that require separate warm-up tools or lack direct inbox access; test integration depth before committing to paid plans.
