- Mailshake is a cold email platform for executing outreach campaigns, while TrulyInbox is an email warmup tool for improving deliverability. Mailshake sends your actual sales emails with features like A/B testing and mail merge. TrulyInbox warms up your email domain through automated interaction simulation to prevent your emails from landing in spam. They serve different stages of the outbound workflow and are typically used together rather than as alternatives.

For more robust functionality, expect $78/mo combining Mailshake's Starter plan ($29/mo) with TrulyInbox's Starter plan ($29/mo for 100 warmup emails daily). Many teams invest in both because they address different bottlenecks: campaign execution versus deliverability preparation. The combined cost depends on your email volume and feature requirements.
- Can Mailshake replace TrulyInbox for email warmup?
- Mailshake includes unlimited email warmup as a feature, so it can handle basic warmup needs. However, TrulyInbox is a dedicated warmup tool with specialized capabilities like customizable reply rates, ramp-up schedules, and real-time deliverability scoring. If your deliverability is already strong, Mailshake's built-in warmup may suffice. If you're struggling with inbox placement or managing multiple domains, TrulyInbox's focused features provide more control and monitoring.
