Get a good open rate by warming up your new address before sending cold emails.

Sending bulk emails right after purchasing a new domain is a surefire way to get blacklisted. Make sure your future recipients actually receive your cold emails by taking the time to send and receive normal (warm) emails first.

When you purchase a new domain, the host will be keeping a close eye on your account to ensure that you aren't a spammer. And if you confirm their suspicions, your email campaigns will suffer. According to Hans Dekker of Wiza, many founders who now have low open-rates were probably blacklisted early on when they were sending from a fresh domain. He recommends warming up your email by getting some activity going first. Email colleagues and friends, then reply to their responses. Subscribe to newsletters. When you start sending cold emails a few weeks later, keep it under 20 per day and don't send them all at once. From there, you can slowly increase your cold emails. You should be on pretty solid ground after a month but it's best to play it safe for about three months.
