PureMail is a team that sets everything up and connects it, billed monthly. Here is how the two cold email infrastructure providers compare.

InboxKit only fits if
The mailboxes are the same kind: Google Workspace and Microsoft 365 on both. What differs is the service and the terms. InboxKit is a self-serve tool paid from a prepaid wallet that is forfeited if you close the account. PureMail is a team that does the setup and the sequencer connection, billed monthly, and it costs less from 101 inboxes up.

Mailbox type
An InboxKit mailbox is a real Google Workspace or Microsoft 365 account, and so is a PureMail inbox. Both send through Google’s or Microsoft’s own servers and start with the reputation those providers give their customers.
What differs is who builds it and how you pay. On InboxKit you top up a wallet, buy domains in the app, create the mailboxes and connect them to your sequencer yourself. On PureMail our team does the whole job, including connecting each inbox to your sequencer, and you pay monthly.
So InboxKit vs PureMail comes down to whether you want to do the setup yourself from a prepaid wallet, or hand it over and pay by the month.
PureMail is a reseller for both. See our Google Workspace reseller inboxes and Microsoft 365 reseller inboxes for cold email.
PureMail
InboxKit
Setup
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.
Warm up in your sequencer for two to three weeks at no extra cost, then send around 30 cold emails a day per inbox.
It is self-serve and automated: SPF, DKIM and DMARC are configured for you, and you create the mailboxes and connect them through its integrations or the API. Its own pages give 10 minutes in one place and 30 to 120 minutes in another.
Its warmup is an add-on at $3 a mailbox a month, which doubles the price of a warming mailbox, or you warm up in your sequencer.
Why switch
The same Google Workspace and Microsoft 365 mailboxes, without doing the setup or prepaying a wallet.
We write the DNS, create every inbox with its sender name and connect it to your sequencer. You click nothing.
Pay monthly. Nothing sits in a non-refundable balance that is forfeited if you leave.
$580 against $600 for 200, $1,450 against $1,500 for 500, month to month, at a published price.
Warm up in your sequencer instead of paying a $3 a mailbox add-on.

FAQ
Is InboxKit good, what it costs, and how to move across.
01
InboxKit is a self-serve cold email infrastructure provider of Google Workspace and Microsoft 365 mailboxes for cold email, at one flat rate per mailbox paid from a prepaid wallet, with automated DNS, an admin panel, an API and integrations with the major sequencers.
02
It is a capable self-serve tool with admin access and an API. The trade-offs: you do the setup yourself, everything is paid from a wallet whose top-ups and fees are non-refundable, warmup costs $3 a mailbox extra, and its own pages disagree on pricing past 200 mailboxes. PureMail sells the same kind of mailbox with the setup done for you, billed monthly.
03
As of the date shown, $3 a mailbox a month on monthly billing, $2.70 quarterly and $2.50 annual, the same for Google and Microsoft, paid from a prepaid wallet. Warmup is $3 a mailbox a month extra and domains are sold in the app.
04
From 101 inboxes, no: PureMail is $2.90 against $3 month to month, $580 against $600 for 200. Under 101, InboxKit is 10 to 30 cents an inbox cheaper, for setup you do yourself. Its quarterly and annual rates are lower, but they are prepaid into a non-refundable wallet.
05
Both, at the same price, plus Azure tenants for Microsoft. PureMail sells Google Workspace and Microsoft 365 too, set up and connected for you.
06
Its pricing lists warmup as an add-on at $3 a mailbox a month, though its homepage table calls it built in. PureMail inboxes warm up in your sequencer at no extra cost.
07
Its terms say wallet top-ups, mailbox fees and domains are non-refundable, and an unused balance is forfeited if you close the account. PureMail bills monthly, so you never prepay more than a month.
08
Yes. Set up PureMail inboxes on your domains, warm them up in your sequencer while your current mailboxes keep sending, then move campaigns across and cancel each old mailbox before it renews.
