The short answer: which one fits you.

Choose PureMail if

  • You want about 30 cold emails a day from each inbox, not 12 or 3
  • You want one charge a calendar month, not one every 29 days
  • You want inboxes connected to your sequencer, not sent as a CSV
  • You want to cancel from a dashboard, not by WhatsApp 5 days ahead

Puzzle Inbox only fits if

  • You want pre-warmed inboxes delivered ready to send
  • You want the cheapest Outlook capacity and will run hundreds of inboxes at 3 a day
  • You need fewer than 30 Google inboxes and accept 12 a day each

Both set up Google and Microsoft inboxes for you. Per Google inbox the prices are close: about $3.15 a calendar month on Puzzle Inbox against $3.30 to $2.90 on PureMail. The gap is the work each inbox does: Puzzle Inbox plans for 12 cold emails a day on Google and 3 on Outlook, PureMail for about 30, so the same volume costs less on PureMail.

What a Puzzle Inbox inbox actually is

A Puzzle Inbox Google inbox is a Google Workspace account, the same kind as PureMail’s, and its Outlook inboxes run in real Microsoft 365 tenants. Both companies set them up for you. The difference is how much each inbox is meant to send and how you receive it.

Puzzle Inbox plans for 12 cold emails a day per Google inbox, three to a domain, and 3 a day per Outlook inbox, 100 to a domain. That is how $0.35 Outlook inboxes work: you spread volume across hundreds of them. You get a CSV of credentials to load into your sequencer, with two-factor login switched off.

PureMail plans for about 30 cold emails a day per warmed Google Workspace or Microsoft 365 inbox, two to a domain, and connects every inbox to your sequencer for you. So Puzzle Inbox vs PureMail comes down to cost per email sent, not per inbox.

PureMail is a reseller for both. See our Google Workspace reseller inboxes and Microsoft 365 reseller inboxes for cold email.

Setup

Setup, delivery and warmup: Puzzle Inbox vs PureMail

PureMail

You choose the inbox count, Google Workspace or Microsoft 365 (or both) and your domains. Our team writes MX, SPF, DKIM and DMARC on every domain, creates each inbox with its sender name and connects it to Instantly, Smartlead, ReachInbox or the tool you send from. A typical order is live in about four hours.

Warmup runs in your sequencer at no extra cost. Plan two to three weeks before full volume, then around 30 cold emails a day per inbox.

Puzzle Inbox

You pay, then fill in an onboarding form with inbox names, your sending tool and your domain. Its team writes the DNS and creates the inboxes in 24 to 72 hours, longer for 200 or more, and sends a CSV of credentials by WhatsApp or email.

Standard inboxes are warmed in your sequencer; pre-warmed inboxes ($4.50 Google, $0.50 Outlook) are warmed for 14 days on its seed network, on its own domains.
