Many people ask questions about how long it takes to warm up a domain or IP. Usually, it takes 3 to 4 weeks and in some cases, it will take more time. But there’s no correct timeline to warm up the email address. Because there are numerous factors to consider, such as

Domain Age: Depending on domain age email warm-up timelines differ. For new domains, it takes a longer time compared to the old domains.

Domain Reputation: If your domain reputation is weak and the ISPs detained your email as spam or blacklisted then it will take a longer time to warm up your email account.

Email Volume: If you are sending high-volume emails and wanted to warm up your email account for bulk email sending then it will take a longer time compared to a low-volume sender.

Subscriber Interaction: The email warmup timeline also involved how people are interacting with your email messages. High email interaction reduces the email warmup timeline.

In addition, it is not just sending or engaging with your emails. For each email that goes to spam, you have to mark it as “not spam”. This method is also called whitelisting your email account.

These are the factor involved in the domain and IP warmup process. Depending on these factors you can tell how much time will take to warm up the email.



Sending too many emails too quickly can result in the domain and IP address being flagged as spammer. During the email warmup process, it is important to send only quality emails with meaningful content. Delivery rates can be further increased by engaging with subscribers and paying attention to feedback loops.
