How it works

Your email, set up properly — without the usual afternoon lost to it.

Business email on your own domain, hosted here, with the parts everyone forgets (the records that keep you out of spam, the calendar, the contacts) done for you.

01
Your domain, your name

you@yourbusiness.co.uk — not a borrowed address.

Add your domain and we generate your signing key, hand you the exact records to publish, then check them for you and say plainly what is still missing.

02
The apps you already use

Your phone, your laptop, or right here in the browser.

Webmail is built in, and every mailbox works in the mail app you already have. Most of them find the settings on their own — there is nothing to type in.

03
Not just messages

A calendar and an address book come with every mailbox.

They speak the same standards your phone already does, so appointments and contacts sync beside the mail instead of living in yet another account.

04
It arrives

Signed and authenticated, so your mail reaches the inbox.

We set up and verify the records that prove your mail is really yours. Get those wrong elsewhere and your invoices quietly land in spam — here it is checked for you.

05
Where the customer already is

The message lands next to their quotes, invoices and bookings.

That is the part an ordinary email provider cannot do. It holds the message and knows nothing about the person who sent it.

06
Included

Part of your plan, not another provider bill.

Your included mailbox allowance grows with your plan: 3 on Starter, 10 on Growth, 25 on Scale and 100 on Enterprise. Hosted in the UK.

One continuous result

The message is only the beginning.

A real email changes something. YionMail carries that change through the business instead of leaving it trapped in a thread.

The outcome stays on the record

THE REAL OUTCOMEA message becomes trust, work and revenue.

Built around the relationship

The person behind the address stays known.

From first enquiry to finished work, the conversation remains part of one customer record. That means better replies, cleaner handovers and no lost promises.

  • Shared inboxes without shared confusion
  • Campaign replies return to the customer record
  • Follow-ups can become real tasks and outcomes

Mail, rethought as part of the OS

Less inbox management. More business moving.

01
One customer, one conversation

Every message arrives with the business context already attached.

See the relationship, the work, the invoices and the previous conversation together. Nobody has to search another tool before replying.

02
Email that changes the business

A reply can move the real work forward.

Turn a request into a task, a booking, a quote or a follow-up using the same records the rest of YionStack already knows.

03
Calm, governed automation

Yion drafts, routes and follows through—under your rules.

Routine messages keep moving. Sensitive or consequential sends remain permissioned and ready for approval, with a clear audit trail.
