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.

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.

Puzzle Inbox pre-warmed Google Workspace inboxes start at $4.50 per inbox. Outlook at $0.35. DNS is fully configured and verified. No warmup tool needed. No DNS fixes. No 3 week wait. You connect to your sending platform and start campaigns within 24 to 72 hours.

Verdict: Maildoso and Cheapinboxes both work for testing cold email on a tight budget. Cheapinboxes is cheaper but DNS quality is less reliable. Maildoso is slightly more polished but shared infrastructure adds risk. For campaigns that need to produce revenue, Puzzle Inbox eliminates the hidden costs and delivers measurably better inbox placement from day one.
