Email warm up is the process of gradually gaining the trust of
Email Service Providers (ESPs).
For the greatest user experience, most ESPs have implemented powerful spam detection algorithms.
They are frequently referred to as "spam filters" and scan your email for any strange information. Anything that appears suspicious is instantly removed and classified as spam.
Any emails sent by a new domain that are sent in high quantities will all land in the spam folder.
Sending automated (or manually generated) emails, which are then replied to (again through the system) to demonstrate interaction, warms up your domain. This totally automated method "warms up" your domain. All emails seem trustworthy enough to gain the ESPs' trust.
To promote business conversations and trick email service providers (ESPs), most email warm-up solutions used today rely on AI machine learning supported by a large network.
A proper email warm up requires progressively increasing the number of emails sent while maintaining high engagement rates to convince ESPs that you are a reliable and entertaining sender who merits being in the recipient's primary inbox.
Tip: Warming up your domain consistently throughout email campaigns helps increase email deliverability and improve the efficiency of your entire campaign.
