Puzzle Inbox review (2026): pricing, pros and cons

What Puzzle Inbox is

Puzzle Inbox, run by Puzzle Group FZC LLC, sells Google Workspace and Outlook 365 inboxes for cold email and sets them up for you. You pay through Stripe, fill in an onboarding form with your inbox names, sending tool and domain, and its team configures DNS and creates the inboxes, usually within 24 to 72 hours. It also sells pre-warmed inboxes and publishes a large library of cold email reviews and comparison pages.

The site says it has run since 2023. Its client and inbox counts differ between pages (1,200 clients and 70,800 inboxes on one, 300 agencies and 13,000 inboxes on another), and they are its own figures.

Pricing explained

Prices are per inbox: $3 for Google Workspace and $0.35 for Outlook 365, or $4.50 and $0.50 pre-warmed. The pricing page says “per month”, but the refund policy says subscriptions renew every 29 days. That is about 12.6 charges a year, so $3 a cycle is about $3.15 per calendar month, and 100 Google inboxes cost about $3,776 a year rather than $3,600.

Outlook inboxes come 100 to a domain, and the Outlook page sets a 100-inbox minimum. Volume discounts are described differently on almost every page: 15% from 150 Google inboxes on one, discounts at 50, 100 and 500 on another, none for Outlook on a third. Reseller pricing for agencies needs 100 inboxes a month on a three-month contract. Treat the list price as the price.

Setup and delivery

The work is done for you. Its team writes SPF, DKIM, DMARC and MX, creates the inboxes and delivers a CSV of credentials organised by domain, by WhatsApp or email; it will load them into your sending tool if you ask. Two-factor login has to be off on the receiving account. It names Smartlead, Instantly, Lemlist, Saleshandy, Reply.io, QuickMail and Woodpecker.

Delivery is 24 to 72 hours after the onboarding form, with orders of 200 or more taking three to five business days and pre-warmed Outlook orders one to two weeks.

Sending limits and deliverability

Puzzle Inbox plans for 12 cold emails a day per Google inbox, three inboxes per domain, and 3 a day per Outlook inbox, 100 per domain. The low Outlook limit is what makes $0.35 possible: 1,000 cold emails a day takes about 334 Outlook inboxes, around $117 a cycle. On Google the same volume takes about 84 inboxes. Its inboxes run on Google’s and Microsoft’s own infrastructure, and it says its Outlook inboxes are real Microsoft 365 tenants rather than Azure or Entra.

Terms and support

Refunds are available only before the onboarding form is submitted and within 24 hours of payment. Delivered inboxes, partial periods and suspensions are not refunded. The refund policy offers a replacement “in limited cases” at its discretion, while its Google and Outlook pages promise a free replacement within seven days for suspensions you did not cause. Cancellation needs five days’ notice before renewal, by WhatsApp. Support is by WhatsApp, live chat and email.

Trustpilot shows 3.8 from 23 reviews as of 12 November 2026. Most are five stars, praising fast support; the one-star reviews describe a dashboard that did not work and a cancellation that was ignored and charged $405, which the company disputes.

Who it is for, and who should look elsewhere

Puzzle Inbox suits teams that want Google or Outlook inboxes set up for them, need pre-warmed inboxes, or want very cheap Outlook capacity and can spread volume across hundreds of inboxes at 3 sends a day. It is a weaker fit if you want calendar-month billing, a written replacement policy you can rely on, or more than 12 cold emails a day per inbox.

How PureMail compares with Puzzle Inbox

Both set the inboxes up for you on Google’s and Microsoft’s own infrastructure. On Google Workspace the prices are close: Puzzle Inbox’s $3 every 29 days is about $3.15 a calendar month, against PureMail’s $3.30 at 10 to 29 inboxes, $3.10 at 30 to 100 and $2.90 from 101, billed once a calendar month. PureMail plans for about 30 cold emails a day per warmed inbox, against Puzzle Inbox’s 12 on Google and 3 on Outlook, so the same daily volume needs fewer PureMail inboxes. PureMail’s Microsoft 365 inboxes are the same price as its Google ones, connected to your sequencer for you rather than sent as a CSV, and cancelled from the dashboard. Puzzle Inbox is the pick if you want pre-warmed inboxes or the cheapest Outlook capacity per inbox.
