We've gathered all the frequently asked questions regarding email warmup and Warmup Inbox in one place, so that you can find the answers easily. 

Email warmup

What does it mean to warm up an inbox?


Email warmup is a process of preparing a new (or long-inactive) email account for future email outreach, campaigns, etc. It is especially useful for cold email inboxes that usually suffer from lower deliverability rates due to the character of the emails they send. 


Why do I need to warm up my inbox?

Over time, all cold email inboxes inevitably suffer from deliverability issues. A well-administered email warmup will reverse this process and help you maintain and improve your deliverability and reputation. 

Who should be warming up their inbox?

Anyone who is actively sending any kind of cold emails. From marketing teams to lead generation and sales departments, from recruiters to outreach specialists.


How long should I be warming up my inbox?

The longer you keep warming up, the more reputable your inbox becomes over time. So we recommend keeping your inbox synced up to our platform for as long as you are actively using your inbox.

How does it work?
