If you want to avoid landing your email in spam the best option is to use an email warm-up tool. Email warm-up refers to the process of gradually increasing the volume and engagement of outgoing emails from a new or inactive email account. It involves sending a series of emails to build a positive sender reputation and establish credibility with Internet Service Providers (ISPs) and email clients.
The primary purpose of Email Warm Up is to avoid triggering spam filters. When an email account, especially a new one, sends a large number of emails suddenly, it raises red flags for spam detectors.
By warming up the account, you're essentially proving to ISPs that you are a legitimate sender with valuable content to deliver.
