By Puzzle Inbox Team · Apr 25, 2026 · 7 min read
Cheapinboxes targets budget-conscious cold email buyers. This review covers actual deliverability, hidden costs, and whether cheap inboxes are worth the trade-offs.
Cheapinboxes Review: What "Cheap" Actually Costs
Cheapinboxes (cheapinboxes.com) positions itself as the budget option in cold email infrastructure. The name tells you the pitch: cheapest Google Workspace cold email inboxes available. For cost-conscious cold email operators, the appeal is immediate. The question this review answers: what does "cheap" actually cost when you factor in deliverability, support, and replacement churn?
What Cheapinboxes Offers
- Google Workspace inboxes at budget-tier pricing
- Basic DNS configuration
- Bulk ordering
- Email-only support
- Shared infrastructure pool
Cheapinboxes Pricing
The pricing is aggressive:
- Standard Google Workspace inbox: $1.50-3/inbox/month
- No pre-warmed option
- No Outlook 365 option
True total cost with warmup tool (required): $16-28/inbox/month. In line with pre-warmed alternatives at similar price points.
What Cheapinboxes Does NOT Include
- No pre-warming. Every inbox arrives at zero reputation. 2-3 weeks of self-warmup required before cold email sending.
- No Outlook 365. Google Workspace only. No platform diversification available.
- No bulk management tools. 50+ inboxes means spreadsheet management.
- No WhatsApp or fast support. Email only, with response times measured in days.
- No deliverability monitoring. You need external tools (GlockApps, Mailreach diagnostics) to monitor inbox health.
- No DMARC setup by default. Some inboxes arrive without DMARC — you configure manually.
Deliverability Performance
Cheapinboxes deliverability track record:
- Reply rate: 1.5-2.5% (below top-tier providers)
- Bounce rate: 2.5-4%
- Spam placement: 8-14%
- Month-over-month consistency: Variable
Shared infrastructure and lack of pre-warming drive the performance gap vs pre-warmed alternatives.
Hidden Costs of "Cheap" Inboxes
The real cost of cheap cold email infrastructure:
- Warmup tool subscription: $15-25/inbox/month for Mailreach, Warmup Inbox, or similar
- Lost weeks of sending during self-warmup: 2-3 weeks of zero output per inbox
- Lower reply rate due to infrastructure quality: 40-50% fewer meetings from the same campaign volume
- Manual DNS verification time: 30-60 minutes per inbox checking authentication alignment
- Replacement churn: 5-10% monthly suspension rate on shared infrastructure
For 30 inboxes over 6 months, the "cheap" choice costs roughly the same as premium alternatives while producing 40-50% fewer meetings.
Support Experience
Email-only support with slow response times. When inboxes suspend or DNS breaks mid-campaign, you wait days for resolution. For cold email operations with active pipelines, support speed is non-negotiable.
Who Cheapinboxes Is Good For
- Individual cold email operators at very low volume (under 5 inboxes)
- One-time testing where long-term infrastructure does not matter
- Operators with existing warmup tool subscriptions
Who Should Avoid Cheapinboxes
- Cold email agencies with client commitments
- B2B SaaS sales teams needing pipeline predictability
- Operations scaling past 10 inboxes
- Teams without technical DNS experience
