A: The email warm-up feature is a process where you gradually increase the volume of emails you send from a new or inactive email account to establish a positive sending reputation with email service providers. This helps to avoid being flagged as spam and improves deliverability rates.

Email warm-up involves starting with a small number of emails per day and gradually increasing the volume over a period of time. This allows email providers to recognize your account as legitimate and trustworthy
