Google Workspace vs Outlook Mailboxes

Same price, different coupon discount

InboxKit prices Google Workspace and Microsoft 365 (Outlook) mailboxes identically: $3.00/month on monthly billing, down to $2.50 on annual billing. The difference shows up in the coupon: GET50 takes 20% off Outlook mailboxes, versus 15% off Google mailboxes, so Outlook works out slightly cheaper after the discount.

Choose based on your recipient list, not price

Price shouldn't be the deciding factor here since it's close either way. What matters more is where your prospects read email:

• Mostly Gmail or Google Workspace recipients: sending from Google Workspace mailboxes keeps you inside the same ecosystem, which some senders find helps deliverability.
• Mostly Outlook or corporate Microsoft recipients: Outlook mailboxes are the natural match, and the coupon discount is larger.
• Mixed or unknown list: many teams split mailboxes across both providers, so they're not dependent on a single one.

Setup and features are identical

Both providers get the same InboxKit setup: automatic SPF, DKIM, DMARC and MX configuration, a dedicated admin panel per domain, optional warmup at $3.00/mailbox/month, and the same 24+ sequencer integrations. There's no feature InboxKit gives to one provider and not the other.

What about Azure?

Azure mailboxes are also Microsoft 365 accounts, just billed per domain instead of per mailbox. If you need Microsoft mailboxes at scale, compare the per-mailbox cost against Azure's 50% coupon discount rather than the standard Outlook mailboxes.
