Check the actual package on both sides. Copilot's base-licence requirement and commitment remain part of the bill. Superhuman Mail Starter, Business and Email Assistant have different entitlements; a suite or assistant offer should not be presented as the same thing as the Mail client. Also confirm the supported mailbox rather than infer compatibility from an AI drafting feature.

| Pros | **Built into Microsoft 365 apps** people already use, so less change management.; **Grounded in your own Graph data** with existing permissions respected.; **Strong compliance story:** EU Data Boundary, data residency commitments, ISO 27001/42001, HIPAA.; **Agents and Copilot Studio** for custom processes with governance.; **Copilot Chat included** at no extra cost for eligible users. | **Built for speed:** keyboard-driven app with Split Inbox, Snippets, Send Later and read statuses for people who process lots of email.; **Strong follow-up tools:** Remind Me, Auto Reminders and (on Business) follow-up drafts in your voice.; **Real team features:** shared threads and comments that work even for colleagues who don't use Superhuman.; **Two ways to use it:** switch to the Mail app, or keep Gmail/Outlook and add the Email Assistant.; **Business is a bundle:** $33 a month (annual) includes Grammarly, Docs and the Go assistant as well as Mail.; **Clear AI data stance:** no training on your data, per Superhuman's help center, and a public DPA. |
| Cons | **$30/user/mo add-on** on top of a qualifying Microsoft 365 licence.; **Annual commitment** even when paying monthly.; **Usage-based billing** for some advanced AI features makes total cost harder to predict.; **Oversharing risk:** Copilot surfaces anything a user can access, so permissions need cleanup first.; **Anthropic models are excluded** from the EU Data Boundary, which matters for EU tenants. | **No free Mail plan**, and the billing FAQ says the suite has no free trials right now (only Email Assistant advertises 30 days).; **Pricier than inbox add-ons:** Starter alone is $25 per member a month on annual billing, and the most useful AI (Auto Drafts, Ask AI) needs Business.; **Only Gmail and Microsoft 365** accounts; no on-premises Exchange, IMAP or other providers.; **No stated EU data residency**; data may be processed in the US.; **Confusing packaging:** Mail plans, the Superhuman suite and Email Assistant overlap, so check exactly what your plan includes.; **SSO and SCIM need Enterprise.** |

Which should you choose?
Try the proposed email job in the application people will actually use, including reminders and colleague access. We would keep Microsoft as the starting point for broader Office work and investigate Superhuman for a deliberate client change. Buying both needs a defined non-duplicated job, not a speculative speed claim.
