overview

What is Warmup Inbox?

Warmup Inbox is an AI-powered email deliverability tool developed by Warmup Inbox that enables businesses, marketers, and salespeople to improve sender reputation and ensure emails land in the inbox. It automates email interactions through a network of over 30,000 real inboxes to generate authentic engagement signals. The platform is designed to help new or existing email accounts establish a positive sending history by simulating natural email activity, such as sending and receiving non-promotional emails, opening them, marking them as important, and sometimes replying. This process aims to build trust with Email Service Providers (ESPs) and prevent emails from being flagged as spam, particularly crucial for cold email campaigns, sales outreach, and email marketing. If an email lands in spam, the system automatically moves it back to the primary inbox, and it gradually increases email sending volume to mimic human-like behavior.
