By Puzzle Inbox Team · May 10, 2026 · 6 min read

Complete Maildoso pricing breakdown including hidden costs. Per-inbox rates look cheap but warmup and replacement add up.

Maildoso Pricing Overview

Maildoso positions as budget cold email infrastructure with aggressive per-inbox pricing. Understanding the true all-in cost including warmup tools and replacement churn reveals the real pricing picture.

Maildoso Per-Inbox Rates

• Standard Google Workspace: $2-4/inbox/month
• Combo plans (GWS + extras): Slightly higher
• SMTP tier (separate pricing): Volume-based

Hidden Costs

Maildoso does not include pre-warming. True all-in cost requires:

• Warmup tool: $15-25/inbox/month (Mailreach, Warmup Inbox)
• Replacement churn: 5-10% monthly suspension rate on shared infrastructure
• DNS verification time: Manual checking required

True Cost Calculation

30 Maildoso inboxes all-in for 6 months:

• Per-inbox: 30 × $3 × 6 = $540
• Warmup: 30 × $20 × 6 = $3,600
• Replacement churn (8%/month): 30 × 0.08 × 6 × $3 = $43
• Staff DNS verification time: 5 hours × $50 = $250
• Total 6-month cost: $4,433

Compare to Puzzle Inbox pre-warmed: $540-810 for same 30 inboxes over 6 months. Maildoso costs 5-8x more once hidden costs are factored.

When Maildoso Pricing Makes Sense

• Very short-term testing (1-2 months only)
• Operations with existing warmup tool subscriptions
• Teams willing to accept variable deliverability for lowest per-inbox sticker price
