OpenEmail against
HEY
line by line.
Their list price is $10–12 / person / month, 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 strongest opinion in email: screening, the Imbox, the Feed, paper trail. If you want somebody to have decided for you, they have.
Why people move
That opinion is the product, and you cannot turn it off or point an agent at it. OpenEmail has opinions about addresses and none about how you read.

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