InboxKit Outlook Coupon Code 20% Off Outlook Mailboxes

What you get with InboxKit Outlook mailboxes

InboxKit's Outlook mailboxes are Microsoft 365 accounts set up for cold outreach. Each one runs on a US IP, and each domain gets its own admin panel with 2FA. InboxKit sets up SPF, DKIM, DMARC and MX records automatically. Microsoft 365 costs the same as Google Workspace, with no Microsoft premium.

• $3.00/mailbox monthly, $2.70 quarterly, or $2.50 annually
• Exports to 24+ sequencers, including Instantly and Smartlead
• Unlimited team members and workspaces, plus API access with webhooks
• Optional isolated warmup for $3.00/mailbox/month

How much GET50 saves on Outlook

At the monthly list price of $3.00, 20% off brings each Outlook mailbox to $2.40. On 50 mailboxes, that saves $30.00 a month. If your checkout also applies it to quarterly or annual billing, the total drops further. Our savings calculator shows each billing term.

Getting good results from Outlook mailboxes

• Spread mailboxes across several domains (2–3 per domain is common), so no single domain carries all your volume.
• Warm up new mailboxes before sending. InboxKit's warmup runs on an isolated network for 14 days.
• Increase daily sends gradually, and keep an eye on bounces. InfraGuard (free for the first month) alerts you if a domain appears on a blacklist.
• Match the provider to your list. Outlook mailboxes suit Microsoft-heavy B2B audiences, and many teams run Outlook and Google side by side.

Outlook or Azure?

Both run on Microsoft. Outlook mailboxes are priced per mailbox, which suits smaller or mixed setups. Azure is priced per domain for up to 100 mailboxes, and GET50 takes 50% off it. If you need a lot of Microsoft inboxes, check the Azure coupon first.
