CUSTOM DOMAINS

Your name, on a
domain you own

Put your address on a domain you own, on any plan including the free one. Bring your old mail with you, and take everything with you again if you ever want to.

ADD

A real domain,
on every plan.

Bring a domain you own and set it up in minutes. Free covers one, and nothing about it is a teaser. It reads and sends like any other address, because it is one.

Bring your own domain

Add a domain you already own. Point it somewhere else one day and your address goes with you.

Import in one pass

Bring your history over from Gmail or any IMAP mailbox without a migration project.

Standard IMAP and JMAP

Connect any client you like, any time, and pull everything down.

No per-person fee

A custom domain on the free plan, with no upsell standing between you and your own name.

VERIFY & SIGN

One record to prove it. We generate the rest

A single TXT record at your domain root proves it's yours. Nyxe generates the MX, SPF, DKIM and DMARC records too, so you publish what we give you instead of hand-crafting keys, and signing is automatic.

RECORDS WE GENERATE

Publish what we give you. Skip the key-wrangling.

One TXT proves ownership. MX, SPF, DKIM and DMARC handle routing and signing, and every value is generated for you, so no private key ever has to be copied by hand.

Signing, keys and all

Signing keys are generated when you add the domain. Publish the DKIM record we give you and your mail is signed automatically. The private key never leaves Nyxe.

More than one domain

Run several domains from the same mailbox and manage them in one place, each with its own status.

Receiving once MX is live

Point the MX record we give you at Nyxe. Once the domain verifies, mail addressed to your new name starts arriving.

SEND

Send as anything you own

Reply from an alias, a second verified domain, or a shared team address like support@. You choose per message, from one picker, without switching accounts.

SEND AS

Pick the address that fits the reply.

One mailbox, every address you own. Answer a customer from support@, a client from your own name, and a supplier from a second domain, all without switching accounts.

ray@nyxe.appdefault
ray@vividx.ioalias
support@nyxe.appshared

Aliases that just work

Add an alias to any domain you've verified and send from it straight away. No second inbox to check.

Shared addresses

support@ and billing@ are real shared mailboxes your whole team reads and sends from together, not forwarding tricks.

One picker, every identity

Set the address new mail goes out as, then switch it per message from the same place, so you never answer from the wrong one.

MANAGE

Yours to run, yours to leave

More domains as you grow, and no lock-in when you don't. The mailbox is standard and the domain is yours, so leaving is always an option you can take without asking.

More domains as you grow

One on free, three on Pro, ten on Team and Business. Add them under the same mailbox, each verified and signed on its own.

No lock-in, ever

Nyxe runs on open protocols rather than a walled garden, and your domain is yours. Point it somewhere else whenever you like. Nothing here needs our permission.
