We never run a meter.

Most 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.

Where a vendor does not document something, it says so rather than pretending the answer is no.
