Nextmail against
HEY
line by line.
Their list price is $10–12 / person / month, checked in September 2026. Ours counts domains and sends, never people, so set the dials below to your own team and volume.
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. Nextmail has opinions about addresses and none about how you read.
most mailboxes bill per seat; two or more needs Starter
ours steps at 1, 50 and 500; Proton, HEY, Resend, Fastmail, Postmark and Mailgun charge more
Sending APIs and Mailchimp bill by volume; mailboxes cap it per seat
unlimited on every plan of ours; Proton and Fastmail tie them to seats
Google WorkspaceBusiness Starter
SuperhumanStarter + WorkspaceMost of these sell one piece of the job: a mailbox, a sending API, a campaign tool or an app that needs a mailbox from somebody else. The Nextmail price is the whole job, with mailboxes on your own domains, sending and receiving, the full API and the AI assistant on every plan. So this is not even a fair comparison: every other bar buys one piece, and ours buys all of it.
Line by line.
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.
