Email warmup: 3 mailboxes for what others charge for one
WarmInbox — Email Warmup is an innovative SaaS tool designed to help email marketers, sales teams, and outreach professionals improve their deliverability and inbox placement. Unlike traditional warmup solutions that charge per mailbox, WarmInbox offers a cost-effective approach by providing multiple mailboxes on its plans—3 on the Starter plan and up to 10 on Pro—making it an attractive choice for teams managing multiple campaigns. The platform connects via SMTP/IMAP and simulates human-like email activity by sending realistic emails daily between a pool of real accounts, marking them as read, and replying at a 40% rate. Over four weeks, users can observe their warmup score rise from 0 to 100, indicating improved sender reputation. It works seamlessly with Gmail, Outlook, and custom domains, making it versatile for various workflows. The free plan with a single mailbox and no credit card requirement makes it accessible for newcomers to test its capabilities.
