Email Warmup Guide
What is Email Warmup?
Email warmup is the process of gradually increasing email sending volume from a new domain, mailbox, or dedicated IP address to establish a positive sender reputation with mailbox providers such as Gmail, Outlook, Yahoo, and other email services. Proper warmup helps improve inbox placement, reduces the likelihood of spam filtering, and builds long-term email deliverability.
Why Email Warmup Matters
Mailbox providers closely monitor sender behavior. When a new domain or IP suddenly sends large volumes of email, it can trigger spam filters and damage sender reputation. A structured email warmup strategy demonstrates legitimate sending patterns and helps establish trust with receiving networks.
Key Components of Email Warmup
Domain Reputation
Your sending domain must develop a history of responsible email practices and positive recipient engagement.
Dedicated IP Warmup
New dedicated IP addresses should gradually increase sending volumes over several weeks to build credibility with mailbox providers.
Email Authentication
Proper configuration of SPF, DKIM, and DMARC records is essential for establishing sender identity and protecting email integrity.
Engagement Signals
Positive actions such as opens, replies, and clicks help strengthen sender reputation and improve inbox placement.

Increase sending activity gradually.
Verify email lists before sending.
