## About Warmup Inbox
Warmup Inbox is an email warmup service that automatically raises your email sending reputation through our network of inboxes talking to each other. The process of preparing an email address for general use or email outreach is commonly referred to as “Warming Up” an inbox, where you take a number of steps to ensure that an email address does not become deactivated, blacklisted, or automatically marked as spam when it begins to send outgoing messages to other recipients. This process is typically done with newly created email addresses but also benefits older email addresses who have been having issues with email deliverability, in that a noticeable portion of their outgoing mail is either landing in a spam folder or blocked entirely by an email server due to either being blacklisted or associated with a domain that has a poor reputation.
