Moreover, it is not just about the tooling, but about the outcomes it enables for your team. In conclusion, please do not hesitate to reach out if you have any questions.

Who it is for
One mailbox.
Four ways in.
The same product underneath, described for the person reading it. Start wherever you recognise yourself.
What you stop paying
Compare the bill.
Move the slider.
The mailboxes multiply by headcount and the sending tools by volume. We sell four plans, so the tenth teammate costs what the second did.

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.
