At InboxKit, you can create mailboxes on Google Workspace, Microsoft 365, and Azure directly from your dashboard — with automated setup, authentication, and activation included.
Follow this step-by-step guide to purchase and activate new mailboxes.
Step-by-Step Process
Step 1 — Go to the Mailboxes Section
Login to your InboxKit dashboard
From the left-side menu, click Mailboxes
Click Buy Mailbox on the top-right
📌 You will now be on the mailbox purchase screen.
Step 2 — Choose Your Mailbox Platform
InboxKit supports three platforms:
Google Workspace
Microsoft 365
Azure
Select your preferred platform by clicking the platform button.
📌 Platform capacity and sending volume differ, so pick the platform that matches your setup:
Google Workspace & Microsoft 365 — up to 5 mailboxes per domain
Azure — up to 100 mailboxes per domain, with a recommended sending volume of about 2 cold emails plus 5 warmup emails per mailbox per day (7 total). For example, 50 mailboxes on one domain supports about 350 emails per day. These are recommended volumes, not hard caps.
Step 3 — Enter Mailbox Details
Fill in the required fields for each mailbox:
