Regie.ai starts with a free tier offering 250 one-time credits. The Pro plan costs $49/mo. This plan is primarily a copywriting tool. The autonomous agent feature, which many users seek, is behind Enterprise quote-only pricing. Credit consumption is fast and often opaque. 5,000 monthly credits do not support a large outbound motion. The actual cost for significant usage can quickly exceed the stated prices. Factor in the need for human editing. This adds to the total cost. The free and Pro tiers are for testing, not scaling.

Warmbox offers a Solo plan at $19/mo, or $15/mo when billed annually. This is for a single mailbox. The jump to the Startup tier is a 4x price increase. There is no intermediate tier for users with two to four mailboxes. This pricing structure means you pay significantly more for a small increase in mailboxes. Warmbox's feature set is minimal. It focuses purely on warmup. This keeps the base cost low. However, you might need other tools for diagnostics or spam testing. This adds to the overall expense.
