You can have two ways. One is manual, one is automatic. Both ways work in this exact same way which is basically you're going to be sending emails gradually increasing them over the course of 30 days. You're going to be sending emails to people who are going to then respond to those emails, remove them from spam if they ended up in spam, mark them as important and then the email provider sees the communication happening. So like you see that you're getting responses, you're not spamming people. After a month, your email domain, your email address is so warmed up already because of all of this communication that you're having that you're ready to start your outbound and then you will not go to spam. This is where the mistakes happen with sales managers because they hire a new sdr, they just give them a new email address and start blowing up like 300 emails per day all of a sudden. It's a huge red signal for the email providers.
