Inframail is cold email infrastructure priced as a flat subscription instead of per mailbox. It provisions unlimited Microsoft-backed inboxes on your domains, sets up SPF, DKIM and DMARC automatically, attaches dedicated US IPs and exports inboxes to sequencers such as Instantly and Smartlead. The plan you pick is really a monthly sending allowance, so size it from your volume forecast, not inbox count.
