What Is Email Warmup?
Email warm up is considered as a process of increasing email sending volume gradually, and generating positive engagement signals such as opens, replies, and clicks. These signals even help email providers like Gmail, Outlook, and Google Workspace to identify your inbox as a trustworthy inbox.
Gradual Sending
Emails are sent slowly and increase over time, which protects your inbox and maintains uniform deliverability.
Build Sender Trust
Helps in generating real engagement signals that assists Gmail and Outlook to trust your domain and sender identity.
Protect Reputation
Avoid damaging your sender reputation before even launching any cold email campaigns while protecting it from spam placement and blacklisting.
