Email Warming: Building Sending Reputation on a New Domain

Email Warming

Email warming is the practice of building sending reputation on a new domain or IP by starting small and increasing volume over time, so mail reaches the inbox instead of spam.

The idea

A new sender has no track record, and mailbox providers treat unknown high-volume senders as suspect. Warming means looking like a real, growing sender: small at first, engaged recipients, gradual increases. It's the same practice covered in depth on the email warm up page.

How Nitrosend automates it

Warmup is enforced automatically with a per-plan daily cap tied to domain age, so a cold domain starts limited and grows as it earns trust. You don't run a manual schedule.
