Email routing for one domain

One domain, two email systems — routed correctly.

Split email delivery and email routing for your domain: send each recipient to the right email platform, keep SPF, DKIM and DMARC intact, and migrate without a big-bang cutover.

  • Recipient-based email routing on a single domain
  • Google Workspace and Microsoft 365 side by side
  • Authentication designed so both systems deliver

Regional service

What is included

A practical service built around reliable configuration, clear ownership and support from one technical team.

Cost optimization

Keep premium seats only for the people who need them and route everyone else to affordable mailboxes — one domain, two price points, one invoice.

Complex email requirements

Departments on different platforms, subsidiaries sharing a domain, regulated teams with their own retention — split delivery lets one address space serve all of it.

Migration without a cutover

Move platform by platform, group by group. Dual delivery keeps mail arriving in both systems while you verify, and the MX follows when you are ready.

A clear route from today’s setup to a working service

We confirm the scope before anything changes and keep the handover understandable.

1. Review

We document what you use today, who needs access and what must be protected during the change.

2. Written plan

You receive the recommended setup, responsibilities and price in writing before work begins.

3. Configure and verify

We complete the agreed setup, test it and hand over the access and operating notes.

Questions before you begin

Can you migrate an existing setup?

Yes. We review the current service, agree what needs to move and plan the change to reduce interruption. The migration scope is confirmed in writing.

Why is there no local price on this page?

This storefront is quote-led because no approved local catalogue is published for this service. We will not invent a converted price; you receive the actual scope and price in writing.

Who provides support after setup?

TK WebHosts provides the agreed technical support. Your written proposal explains what is included, what your team controls and how to request help.

What is split email delivery?

Split email delivery routes incoming messages for a single domain to two different email systems based on the recipient. Mail arrives at a primary server first; recipients who live on the second platform are passed straight through to it.

What is the difference between split delivery, dual delivery and email routing?

Email routing is the umbrella: rules that decide where a message goes. Split delivery sends each recipient to exactly one of two systems; dual delivery copies messages to both systems at once, which is common during migrations and testing.

Can I run Google Workspace and Microsoft 365 on the same domain?

Yes — that is the classic split delivery case. Sales can live in Gmail while operations stays in Outlook, all on the same addresses at your domain.

Does split delivery break SPF, DKIM or DMARC?

Done carelessly, it can — a second hop can hard-bounce mail from strict-SPF senders. We design the routing so authentication survives both paths, and we verify it with real senders before handover.

Is split delivery only for migrations?

No. Migrations are one use, but plenty of businesses run it permanently — to keep premium licences for a few users, to give departments different platforms, or to meet retention rules for one team only.

Will messages get lost between the two systems?

Not in a correct setup. The primary server has an explicit rule for every recipient, unknown addresses are rejected predictably, and we test both paths before anything goes live.

How much does split email delivery cost?

It is scoped and quoted in writing — the design depends on your platforms and mailbox count. In most cost-optimization setups the routing pays for itself by reducing per-seat licence spend.
