Warmupify Review — Honest Pros, Cons & Pricing (2026)

Category: Cold email warmup tool for new inboxes

Also known as: warmupify.

Overview

Warmupify provides automated cold email warmup for Google Workspace and Outlook 365 inboxes. The service simulates organic email activity by sending and receiving emails between warmup accounts, marking messages as important, moving emails from spam to inbox, and building positive sender reputation over 2-4 weeks. For teams buying fresh inboxes without pre-warming, Warmupify provides the warmup layer before cold email campaigns begin. The warmup network rotates across thousands of accounts to produce diverse engagement signals, which helps inboxes build reputation with both Gmail and Outlook infrastructure. Pricing is per inbox per month, making it cost-comparable with Mailreach and Lemwarm at $15-25 range.
