What comes with every Entra domain.
Automated Infrastructure Deployment
Order Google or Entra infrastructure with DNS, inbox and outbound settings, warmup enabled, and direct sending-tool upload handled in one workflow.
Reply Relay
Replies sent to canceled domains keep routing into the central inbox you choose, so a prospect who answer smonths later still reaches you.
Domain Layover
When you replace an Entra domain, the outgoing domain keeps sending for 14 days while the new one warms, so you keep capacity without paying for duplicate domains.
Recovery Pool
Keep reserve domains resting in recovery without paid sending inboxes, then order inboxes with one click when needed.
Email Placement
Free domain-level placement tests that tell you whether copy or infrastructure is the likely problem.
Hypertide Stealth
Conditional URL forwarding that redirects real visitors without giving crawler-style requests the same destination path.
Distributed Enterprise Nameservers
Domains purchased through Hypertide are spread across apool of 100 nameservers, so the fleet stops sharing onerepeated fingerprint.
How ordering works
From order to sending.
01
Choose domains
Bring your own or order through Hypertide. Each domain gets 25 inboxes.
02
Tenant and DNS are built
Separate tenant, enterprise SPF/DKIM/DMARC and Outlook.com logins are configured for you.
03
Inboxes are delivered
Typically 4–6 hours after the order. Ordering starts the process; it is not instant.

Moving platforms
Move to Google without rebuilding.
If a client or a campaign suits Google better, the move is a Hypertide workflow, not a manual migration.

Customer proof
What cold-email operators say about Hypertide.
“Hypertide has completely changed the way we approach deliverability. It's hands-down the most effective tool we've used to keep our domains warm and our emails landing in the inbox. The automation is seamless, and the results speak for themselves. If you're serious about cold email, Hypertide is a must-have.”

“Onboarded a customer that wanted to only target companies with over $5B in revenue and above. Hypertide.io is breaking into their inboxes for us. Usually, I give my whole song and dance about how I don't like doing outbound to really large companies—the TAM is small, it's tough to break through their spam filters. But this company has a really compelling offer with great case studies, so I thought, if anyone can break in, they will.”

“216,900 email accounts. 4,427 domains. Under 3 months. From zero. We brought on Hypertide.io as an infrastructure vendor—within the first week they processed 100+ orders across 135+ client brands: 1,700 domains and 85,000 inboxes, uploaded, warmed, tagged, and connected to multiple sequencers with 24-hour turnaround. Then we migrated 40,000+ inboxes between platforms while keeping campaigns live. Hypertide did it in waves across 3 weeks.”
