Good thinking — jumping into bulk emailing too soon is a recipe for disaster. You definitely need to warm up your domain first. I use the top email warm up https://snov.io/email-warm-up tool , and it’s super helpful. It automates the entire warm-up process by sending emails, getting replies, and even marking them as “important” — just like a real conversation. I’d recommend running it for at least 2–4 weeks depending on your goals. Their dashboard also shows your reputation status, which is a nice bonus.
