Deliverability

95% of the business software market runs on Google Workspace and Microsoft 365. Your prospects already trust them — so when you send from them, you increase your chances of landing in the primary inbox, compared with private SMTP or unknown servers.

Source: combined Google Workspace + Microsoft 365 share of the office-productivity software market — Statista, 2025 (Google Workspace ~50% + Microsoft 365 ~45% by domains).

Answers to common questions.

What is Inboxlogy?

Inboxlogy is a cold email infrastructure provider for B2B outbound and sales teams.

Pricing starts at $2.80 per mailbox per month with no setup fee and monthly billing.

How much does Inboxlogy cost?

Pricing starts at $2.80 per mailbox per month at 500+ and $3.50 per mailbox for smaller orders, with a $0 setup fee. Billing is monthly and you can cancel anytime. Every plan includes US and EU sending IPs, admin access, 100% ownership, SPF/DKIM/DMARC authentication, MX and domain authentication, and free connection to any sending tool over OAuth or API.

Do I get admin access and ownership of the accounts?

Yes. You receive admin access to every workspace and are the sole owner of the accounts. You can add, remove or modify domains and users, and if you ever leave Inboxlogy you can set up billing directly with the email service provider — there is no ecosystem lock-in.

How fast can I get started?

Placing your order takes about 10 minutes, even in bulk: choose your domains and mailboxes, let Inboxlogy auto-configure DNS and authentication, then connect your sequencer — Instantly, Smartlead, ReachInbox or any other — where warmup runs. Your mailboxes are then delivered ready to send; how soon you're live depends on order size.

Which sending tools can I connect mailboxes to?

Inboxlogy mailboxes connect to any cold email platform that supports OAuth, app passwords, or IMAP/POP — including Instantly, Smartlead and ReachInbox — at no extra charge.
