OpenEmail against
Superhuman
line by line.
Their list price is $25 / person + a mailbox, checked in August 2026. Ours counts domains rather than people, so the two lines below diverge with the size of your team.
What they are better at
The fastest keyboard-driven reading experience in email, and a genuinely good AI writing layer. Split-second interactions that make an old Gmail feel new.
Why people move
It is a windscreen, not a car. You still pay Google or Microsoft to host the mail, so a five-person team pays $160 a month before anyone sends anything. OpenEmail is the mailbox and the client, for $30 a month.

Line by line.
Every mailbox on one table, Superhuman among them. Where a vendor does not document something, it says so rather than pretending the answer is no.
