What Makes Hypertide Different
A technical breakdown of how our infrastructure and pricing differ from every other Entra and Google provider — and how to verify each claim yourself.

The one question that separates us
"Can I log in on outlook.com?"
Ask any Entra provider. They can't. We can.
Every Hypertide inbox has a real, native Outlook interface. With inbox access you can verify replies actually land — most sequencers miss 8–10% of them.

Pricing
Half the price. None of the packages.
We're hyper-selective about who we onboard, and that selectivity is why deliverability holds.

Questions we get on every call.
Can I really log in on outlook.com?
Yes. Every Hypertide inbox has a real, native Outlook interface — log in on outlook.com, read replies, send manually. No other Entra provider can say that.
Will my inboxes disconnect from my sequencer?
No. Disconnects, disabled warmup, and tenant thresholds are symptoms of typical Entra setups. Our architecture routes replies differently, so none of those apply.
Is there a setup fee?
No setup fee — just a small credit fee. Entra domains are $25/month flat, Google inboxes $3.30/month flat, with every feature included.
What happens when I cancel a domain?
Two things, both free: Layover keeps the domain alive for 18 more days while you spin up replacements, and Relay routes every future reply from that domain to your new inbox — so late responders never bounce.
Do you support Google inboxes too?
Yes — flat $3.30 per inbox. Competitors gate their pricing behind bulk packages with 10-inbox minimums; with us you buy exactly the number you need, from 1 up.
Who do you work with?
We're hyper-selective — we only work with the top 1% of senders. A selective IP pool is exactly why deliverability holds for everyone on it.
