How long does it take to warm up domain if you are going to send cold emails or marketing emails from old or new domains?


Email marketing is an essential part of any successful business, but it can be challenging to get your message to your target audience. One way to improve your email deliverability rates is to warm up your email accounts before sending cold or marketing emails.


So, how much time should you spend warm up email accounts on The answer depends on several factors, such as the age of your domain, the number of emails you plan to send, and the level of engagement you want to achieve.


Generally, we recommend spending at least 2-4 weeks warming up a new email / domain before sending cold emails.

For old domains, you can start with a shorter warm-up period of around 1-2 weeks.

Gradually increase the temperature over time to avoid triggering spam filters and maintain a positive reputation with email providers.



Here are some additional tips for effectively warm up email accounts:
