Warmup Inbox

Warmup Inbox is a software tool designed to improve your email sender reputation and inbox health. The tool enhances email deliverability to ensure your emails reach the intended recipients. It costs $15 per inbox.

Warmup Inbox works by synchronizing your email inbox with its network of over 20,000 continuously changing inboxes. Once integrated, your emails interact with these inboxes to prevent them from being classified as spam. This interaction restores your sender reputation and trains ISPs and Mail Servers to recognize your emails as valid.

The software also monitors your email health, including spam percentage, technical details like DNS settings, DMARC, DKIM, SPF, domain age, security protocols, and more. It checks if you are listed on any blacklists. Warmup Inbox is compatible with all major email providers and any inbox that supports SMTP.
