Hypertide sells two things. Its Google inboxes are standard Google Workspace accounts, the same kind of mailbox as PureMail’s, at $3.30 each. Its headline Microsoft product is different: Outlook inboxes in Microsoft Entra tenants on Azure, 25 to a domain, with up to 3,000 sends a month per domain, which is about 5 a day per inbox.
A PureMail inbox is a standard Google Workspace or Microsoft 365 account on your domain, sending through Gmail’s or Outlook’s own infrastructure at about 30 cold emails a day once warmed.
So Hypertide vs PureMail is two questions: Google inboxes cost less with PureMail from 30 up, and on Microsoft you choose between cheap Entra inboxes that send a few emails a day and standard Microsoft 365 inboxes that send about 30.
