Hypertide
Inbox infraAutomated Google, Microsoft, and Microsoft 365 infra with tenant separation and sequencer auto-upload.
The verdict
Hypertide fills the cheap Microsoft 365 mailbox slot and shows up a lot in O365 cost threads. Prefer the live $3.30 Google inbox and $25 Microsoft 365 domain pricing, confirm there is no setup fee, and verify daily send caps before you model volume.
The small credit-fee dollar amount is still a Gap this pass.
Best for
Operators optimizing Microsoft or Microsoft 365 cost per send, and teams that want automated upload into a sequencer.
Not for
Google-only done-for-you buyers who want unlimited human replacements as the product.
Pricing truth
Google is $3.30 per inbox per month flat. Microsoft 365 domain add-on is $25 per domain per month for 25 inboxes per domain. FAQ says no setup fee. Credit-fee dollars are a Gap this pass. Checked 13 Sep 2026.
When we use it
- Run Microsoft 365 or Azure high-density Microsoft sending when per-mailbox Google Workspace costs hurt.
- Buy flat Google at $3.30 with no 10-inbox package minimum.
- Diversify in parallel beside official-tenant managed vendors.
- Skip when you need done-for-you unlimited replacements and Slack white-glove only.
How to wire it
- Order Microsoft 365 domains and Google inboxes, then wait the usual 4 to 6 hours for automated setup.
- Confirm native outlook.com login on Microsoft 365 before you scale volume.
- Auto-upload OAuth or SMTP credentials into your sequencer.
- Respect per-inbox daily caps, and A/B against other Azure density peers before you forecast.
Margin notes
- Model Microsoft 365 at $25 per domain across 25 mailboxes as about $1 per mailbox sticker, then watch send caps.
- Ignore competitor claims of a $1,500 setup fee. The vendor FAQ says there is none.
- Layover is 18 days plus Relay on cancel, which helps catch late replies.
- Onboarding is selective. This is not a free-for-all shared pool pitch.
- Always A/B Microsoft 365 caps before you forecast something like 150 sends per day per domain.
