This comparison is published by GoogleWorkspace Resellers, an independent directory and information resource covering Google Workspace resellers and cold email infrastructure providers. We checked Google’s Cloud Partner Directory directly for both companies named here. Leads Monky (Leads Monkey Ltd) has a confirmed listing, viewable at the link below. Puzzle Inbox’s own website states it was not found in Google’s Cloud Partner Directory, and we independently checked the directory and found no listing for Puzzle Inbox. Puzzle Inbox does carry an independent review profile: Trustpilot showed a 3.8 out of 5 TrustScore from 23 reviews at the time of writing, and a Capterra listing showed a 5.0 out of 5 rating from a single review, too small a sample to treat as a meaningful signal. Every pricing figure below comes from either company’s own published pricing pages, and self-reported statistics (active inboxes, client counts, average ratings quoted on the company’s own site) are flagged as such.
Quick Answer
Leads Monky is the stronger overall choice on verified Google partner status, flexible order sizes, and pricing at most volumes. One genuine exception stands out: at low order sizes, Puzzle Inbox’s Standard plan at $3 per inbox per month is actually cheaper than Leads Monky’s 1 to 10 mailbox rate of $3.70, before Leads Monky’s volume discount kicks in at 11 or more mailboxes. Puzzle Inbox is built specifically for cold email teams that want a done-for-you setup, including domain purchasing and pre-warmed inboxes delivered in 24 to 72 hours.

Puzzle Inbox’s own site states it was not found in Google’s Cloud Partner Directory.
Google Partner / Reseller Status
| Feature | Leads Monky | Puzzle Inbox |
|---|---|---|
| Google Partner / Reseller Status | Authorized Google Workspace reseller, verified through Google Partner Directory (listing) | Not listed as an authorized Google partner/reseller; confirmed independently as not found in Google’s Cloud Partner Directory |
| Trustpilot rating | Not the subject of this check | 3.8 out of 5 from 23 reviews (verified independently) |
| Capterra rating | Not the subject of this check | 5.0 out of 5 from 1 review (sample too small to be meaningful) |
Pricing Comparison at a Glance
Puzzle Inbox prices two separate Google Workspace tiers: Standard, at $3 per inbox per month with no pre-warming, and Warmed, at $4.50 per inbox per month with pre-warmed sending reputation. Both require a minimum of 3 inboxes per domain. Leads Monky prices per mailbox with volume discounts and no per-domain minimum.
| Volume | Leads Monky (per mailbox/mo) | Puzzle Inbox Standard | Puzzle Inbox Warmed |
|---|---|---|---|
| 1–10 | $3.70 | $3.00 (minimum 3/domain) | $4.50 (minimum 3/domain) |
| 11–29 | $3.00 (≤20/domain) | $3.00 | $4.50 |
| 30–99 | $3.00 (≤20/domain) | $3.00 | $4.50 |
| 100–299 | $3.00 (≤20/domain) | $3.00 | $4.50 |
| 300+ | $2.60 (≤20/domain) | $3.00 (bulk pricing available, rate not published) | $4.50 (bulk pricing available, rate not published) |
Puzzle Inbox’s homepage headline of “$0.35/inbox” refers specifically to Outlook 365 inboxes, confirmed on its own FAQ page, and does not apply to its Google Workspace Standard or Warmed plans. A $3.85/user/mo surcharge applies to a Leads Monky order only when the average mailboxes-per-domain across the whole order exceeds 20.
Full Cost Comparison by Volume (Annual)
| Mailboxes | Leads Monky / year | Puzzle Inbox Standard / year | Puzzle Inbox Warmed / year |
|---|---|---|---|
| 10 | $444 | $360 | $540 |
| 30 | $1,080 | $1,080 | $1,620 |
| 50 | $1,800 | $1,800 | $2,700 |
| 100 | $3,600 | $3,600 | $5,400 |
| 300 | $9,360 | $10,800* | $16,200* |
| 500 | $15,600 | $18,000* | $27,000* |
*Puzzle Inbox’s published $3.00 and $4.50 rates carry through at these volumes since no specific bulk discount tier is published; its site mentions bulk pricing for 500+ inbox orders without stating the discounted rate, so the real cost at that volume could be lower than shown.
At 10 mailboxes, Puzzle Inbox’s unwarmed Standard plan is genuinely cheaper than Leads Monky’s entry rate, since Leads Monky’s $3.00 volume rate only applies from 11 mailboxes onward. From 30 mailboxes up to 299, the two land at the same $3.00 rate on the Standard tier, before Leads Monky’s rate drops to $2.60 at 300+ and pulls ahead again. Puzzle Inbox’s Warmed tier, which includes pre-warming, costs meaningfully more at every volume shown.
Reasons Leads Monky Is the Stronger Choice
- Lower cost at 300+ mailboxes, where Leads Monky’s published $2.60 rate beats Puzzle Inbox’s published $3.00 Standard rate, since Puzzle Inbox’s bulk discount for that volume isn’t published.
- Verified Google Partner Directory listing, giving a documented, checkable authorization status Puzzle Inbox doesn’t have.
- No minimum order. Puzzle Inbox requires 3 inboxes per domain minimum; Leads Monky has no such requirement.
- Serves both business email and cold email customers under one provider, rather than being built exclusively around cold outreach infrastructure.
- Full Admin Console ownership, with customer-controlled passwords, aliases, and settings, which isn’t published as a feature on Puzzle Inbox’s site.
- No contract and no long-term commitment, versus Puzzle Inbox’s cancellation policy requiring at least 5 days’ notice before renewal.
- Migration support for Zoho, Microsoft 365, and Google Workspace environments, which isn’t mentioned on Puzzle Inbox’s site.
- Live support, WhatsApp support, and phone support, compared to Puzzle Inbox’s WhatsApp-only support during business hours.
- Global support across 50+ countries, rather than a single cold-email-infrastructure-focused storefront.
- Calendar month billing with transparent, unconditional volume pricing, rather than an unpublished bulk rate that only applies at 500+ inboxes.
Where Puzzle Inbox Falls Short
- Not listed in Google’s Cloud Partner Directory, a fact the company discloses itself, and one we independently confirmed.
- Headline “$0.35/inbox” pricing applies to Outlook 365, not Google Workspace. Its own FAQ confirms Google Workspace inboxes actually cost $3 to $4.50/inbox/month.
- Mandatory minimum of 3 inboxes per domain, which rules out a buyer who wants a single mailbox on a domain or a smaller, more flexible setup.
- Low daily sending cap. Both Standard and Warmed plans cap sending at 12 emails per inbox per day, which may be restrictive for a team used to scaling volume per mailbox rather than mailbox count.
- Cold-outreach-first product design. There’s no standard Google Workspace business email plan for a company that just wants normal company inboxes rather than campaign infrastructure.
- Admin ownership isn’t clearly published. The site describes a done-for-you setup and a shared management dashboard, but doesn’t state whether the customer retains full administrative control of the underlying Google Workspace account.
- No migration support published for teams moving from an existing business email provider.
- Bulk pricing for 500+ inboxes isn’t published, so the real cost advantage at scale can’t be confirmed from the site alone.
- Cancellation requires 5 days’ notice before renewal, a condition Leads Monky’s no-contract model doesn’t impose.
- Testimonials on its own site are not the same as independent reviews. Its “4.7/5 by our clients” figure comes from its own homepage; the independently verifiable Trustpilot score is lower, at 3.8 out of 5.

Setup and Admin Ownership
Leads Monky gives customers full ownership of the Google Admin Console from day one, with the option of a separate Admin Console per domain or one centralized Admin Console across all domains, depending on what the customer needs. DNS setup (SPF, DKIM, DMARC) is handled as a humanized, custom configuration for each account, typically taking 4 to 5 working hours.
Puzzle Inbox’s process is built around a done-for-you model: the customer orders inboxes through the dashboard, and Puzzle Inbox handles domain purchasing, DNS records, SPF, DKIM, DMARC, and OAuth configuration, delivering ready-to-send inboxes in 24 to 72 hours. What isn’t published is who retains administrative ownership of the underlying Google Workspace account once setup finishes, a detail worth confirming directly with Puzzle Inbox before ordering if long-term account control matters for your setup.
Who Should Choose Each Provider
Choose Puzzle Inbox if: you run cold outreach campaigns exclusively, want domain purchasing and setup fully handled for you, are comfortable with a mandatory 3-inboxes-per-domain structure and a 12 email per day sending cap, and are weighing its lower entry price at small volumes against its unverified Google partner status.
Choose Leads Monky if: you need standard business email, cold email infrastructure, or both under one account; you want full Admin Console ownership and a verified Google partner relationship; you want a single mailbox or a flexible order size without a per-domain minimum; or you need migration support moving from an existing provider. If neither provider fits, it’s worth browsing other Google Workspace alternatives before deciding.
Final Verdict
Puzzle Inbox’s done-for-you setup and genuinely low entry pricing make it a reasonable option for a cold outreach team that wants domains, DNS, and warmup handled without technical involvement, and its Trustpilot profile shows real, if mixed, customer feedback. But its mandatory per-domain minimum, unverified Google partner status, and low daily sending cap are real constraints, and once order volume passes 10 mailboxes, Leads Monky’s pricing, flexibility, and verified reseller status make it the stronger pick for most buyers, especially those who also need standard business email rather than outreach-only infrastructure.

Conclusion
Puzzle Inbox and Leads Monky both provide Google Workspace mailboxes for cold outreach, but they fit different buyers. Puzzle Inbox leans on a done-for-you setup, genuinely competitive entry pricing at low volumes, and a real, if modest, independent review record, while carrying a mandatory per-domain minimum, a low daily sending cap, and no verified Google partner status. Leads Monky is a verified Google Workspace and Microsoft 365 reseller that covers both standard business email and cold email infrastructure, with no minimum order, full admin ownership, and migration support built in, and it pulls ahead on price once order volume passes the smallest tier. For a buyer weighing the two on verified trust, flexibility, and price at scale, Leads Monky is the stronger pick; Puzzle Inbox remains a reasonable option for a small cold outreach setup that values a fully managed, lower-cost entry point.
