Maildoso vs Cheapinboxes: Budget Cold Email Inbox Comparison
Two budget Google Workspace providers go head to head. We compare pricing, DNS quality, warmup, support, and deliverability to help you decide.
Two Budget Providers, One Question: Which Is Less Risky?
If you're shopping for cold email inboxes on a tight budget, Maildoso and Cheapinboxes are probably on your shortlist. Both sell Google Workspace accounts at prices well below what you'd pay direct from Google. Both target cold emailers, SDRs, and agencies who want volume without breaking the bank. But budget doesn't mean identical. There are real differences in infrastructure quality, DNS reliability, and what you're actually getting for your money.
I've tested both providers across multiple campaigns. Here's what I found.
Maildoso: Shared Google Workspace at Scale
Maildoso (getmaildoso.com) sells Google Workspace inboxes at around $2 to $3 per inbox. The pricing is attractive, and they've built a decent reputation in cold email communities. But there's a catch that most buyers don't realize until they're already sending: Maildoso runs on shared infrastructure.
Shared infrastructure means multiple Maildoso customers send through overlapping Google Workspace pools. If another sender on your shared setup burns their reputation (sending too aggressively, hitting spam traps, getting complaints), your deliverability takes a hit too. You didn't do anything wrong. You just happen to be on the same infrastructure as someone who did.
DNS setup on Maildoso is functional but inconsistent. SPF and DKIM are usually configured on delivery, but I've had batches where DMARC records needed manual fixes. If you don't know how to check DMARC alignment, you might send for weeks with broken authentication and wonder why your reply rates are low.
There's no pre-warming option. You'll need a third party warmup tool like Instantly warmup or Warmbox at $15 to $20 per inbox per month. That adds up fast at scale.
Support is email only with 24 to 48 hour response times. If something breaks on a Friday, you're waiting until Monday.
Cheapinboxes: The Lowest Price on the Market
Cheapinboxes lives up to its name. At roughly $1.50 to $2.50 per inbox, it's the cheapest Google Workspace provider I've tested. For solo operators just getting started with cold email, the entry cost is minimal.
But DNS quality varies more than any other provider I've used. About 20% of the inboxes I've received from Cheapinboxes had DMARC issues on arrival. Some batches were perfect. Others needed manual intervention. If you're comfortable with MXToolbox and DNS records, you can fix these yourself. If you're not, you'll need to wait for their email support, which runs 24 to 48 hours for responses.
Like Maildoso, there's no pre-warming. No Outlook option either. You're getting Google Workspace accounts and nothing else.
Deliverability after warmup sits around 58% to 68% inbox placement on GlockApps. That's below the threshold where cold email campaigns generate reliable pipeline.
Head to Head Comparison
| Feature | Maildoso | Cheapinboxes |
|---|---|---|
| Infrastructure | Google Workspace (shared) | Google Workspace |
| Pricing | $2 to $3/inbox | $1.50 to $2.50/inbox |
| DNS quality | Usually OK, occasional DMARC issues | Inconsistent, ~20% need fixes |
| Pre-warming | — | — |
| Outlook option | — | — |
| Warmup included | — | — |
| Support | Email (24 to 48h) | Email (24 to 48h) |
| Inbox placement | 55% to 65% | 58% to 68% |
The Real Cost of Budget Inboxes
The sticker price is only part of the equation. Let's do the math on 30 inboxes for the first month.
Maildoso: 30 inboxes at $2.50 = $75. Warmup tool at $15/inbox/month = $450. Time fixing DNS on ~10% of inboxes = 2 hours. Total first month: ~$525 plus your time.
Cheapinboxes: 30 inboxes at $1.50 = $45. Warmup tool at $15/inbox/month = $450. Time fixing DNS on ~20% of inboxes = 4 hours. Total first month: ~$495 plus your time.
Both providers require you to wait 14 to 21 days for warmup before you can send a single cold email. That's 2 to 3 weeks of paying for inboxes and warmup tools while generating zero pipeline.
When Budget Makes Sense (and When It Doesn't)
If you're testing cold email for the first time with 5 to 10 inboxes and a limited budget, either provider works. You'll learn the fundamentals without a large upfront investment. Just know that your deliverability ceiling is lower than what's possible with better infrastructure.
If you're running campaigns that need to generate revenue, if you're an agency with clients expecting results, or if you're scaling past 20 inboxes, budget providers create more problems than they solve. The warmup costs, DNS fixes, and lower inbox placement eat into your ROI fast.

Maildoso vs Cheapinboxes: what cold email operators actually need to compare
Most "Maildoso vs Cheapinboxes" comparisons online compare feature checkboxes. Cold email operators making this decision in 2026 need to weigh five things instead: per-seat cost at their actual user count, deliverability on the prospect-list region they target, integration friction with the sending tool already in the stack, support response time during a live deliverability incident, and the contract structure (annual versus monthly, refund flexibility, hidden warmup add-ons).
Pricing comparison: Maildoso vs Cheapinboxes
Headline pricing is the first thing most buyers see, but real total cost of ownership depends on what is bundled and what is an add-on. For Maildoso and Cheapinboxes, the dimensions to model carefully are: per-seat cost on the smallest viable plan, the price step from the entry tier to the next tier (where most growth-stage teams end up), credits or sending limits that bottleneck heavy users, warmup tool subscriptions sold separately, deliverability monitoring add-ons, and any minimum-order constraints that inflate the entry point. Pull current pricing directly from the vendor pricing pages; both vendors update tiers quarterly in 2026.
Deliverability and sending infrastructure
For tools in the cold email infrastructure category, the upstream question is which underlying mailbox provider the sending traffic actually leaves from. Real Google Workspace and Microsoft 365 mailboxes inherit Google's and Microsoft's own IP reputation. Custom SMTP infrastructure does not. India-region Workspace tenants carry different region-level reputation signals from US or EU region tenants. If Maildoso and Cheapinboxes differ on this dimension, that single difference outweighs most of the feature comparison. For sending tools and lead data tools, the upstream question is whether the product gracefully connects via OAuth to real GWS / M365 mailboxes from a provider like Puzzle Inbox.
Integration friction with the existing stack
Most operators do not pick Maildoso or Cheapinboxes in isolation. The decision is shaped by what the rest of the stack already runs on. If the team is on Smartlead or Instantly for sending, the integration story is more important than any standalone feature comparison. If the team is on Apollo or Clay for data, the export and webhook compatibility matters more than the prospect database size. The right comparison framework is: "Which one breaks least when bolted onto our existing stack?" not "Which one has more features on a vendor demo deck?"
Support and incident response
Both Maildoso and Cheapinboxes have public support channels. The dimension that separates them is response time during a live incident — a deliverability drop mid-campaign, a sudden bounce-rate spike, an account suspension. Test this before signing by opening a real support ticket on a free trial or paid plan. The vendor that responds in hours instead of days is the one that survives contact with a real cold email operation.
Where Puzzle Inbox fits
Whichever of Maildoso or Cheapinboxes the team picks, the sending infrastructure layer is upstream of the tool decision. Puzzle Inbox provisions real Google Workspace and Microsoft 365 cold email mailboxes on dedicated tenants, ships pre-warmed inventory in 24 to 72 hours, and connects via OAuth (email + password) to every sending tool in this comparison.

Maildoso vs Cheapinboxes FAQ
Which is cheaper, Maildoso or Cheapinboxes?
The cheaper of Maildoso and Cheapinboxes at your specific seat count depends on the tier each vendor places you on. Pull current pricing from both vendor pricing pages on the same day and run the math at your actual user count, your actual sending volume, and your actual feature requirements. The cheaper headline number is often not the cheaper effective cost once add-ons and seat tiers are factored in.
Which has better deliverability, Maildoso or Cheapinboxes?
Deliverability is mostly a function of the sending mailbox provider (Google Workspace, Microsoft 365, or custom SMTP) rather than the tool layered on top. If Maildoso and Cheapinboxes both connect to real GWS or M365 mailboxes, the deliverability difference is small. If one of them is custom SMTP infrastructure and the other is real GWS / M365, the gap is large.
Can I switch between Maildoso and Cheapinboxes later?
Both vendors export contact data, campaign history, and reply data in standard formats. Migration friction is mostly in re-onboarding the team on the new UI rather than data portability. Budget a week for the switch.
What is a good alternative to Maildoso and Cheapinboxes?
The alternatives most cold email operators evaluate alongside Maildoso and Cheapinboxes live in the same category. See the tools directory for the full category list and the comparisons directory for related head-to-heads.
