SENDING DOMAINS, HANDLED

Mail that looks like you, sent from a domain built to match.

Every campaign goes out from a domain registered to your brand, authenticated with SPF, DKIM and DMARC, and hosted on our infrastructure. You never open a DNS panel.

  • Domain registered and authenticated for you

  • SPF, DKIM and DMARC set up automatically

  • Zero DNS records for you to touch

THE PROBLEM

DNS shouldn't stand between you and your list.

Setting up email the regular way means a trip into your domain registrar, copying codes into a DNS panel, and hoping you pasted the right ones into the right boxes. One stray character and SPF fails silently. One skipped record and DKIM never signs a thing. Nobody tells you until your campaigns quietly land somewhere you never check.

Even when the records go in cleanly, half-right authentication is its own kind of trap. A domain with SPF but no DKIM, or a DMARC policy it can't support, reads to inbox providers as unfinished business. Your campaigns might land. They might not. Either way you're guessing, and guessing is a bad way to run a list you've spent months building.

We remove the guesswork by removing the task. You tell us the domain you want to send from, we handle the registration, the authentication and the hosting, and we keep it correct for as long as you're sending. No panel, no codes, no silent failures.

Three records, two typos, zero emails sent.

HOW IT WORKS

From blank domain to inbox-ready in one setup

No tickets, no waiting on an IT contact, no copy-pasting TXT records. Four steps, and every one of them is ours to do.

Marching your domain straight to go-live.

Tell us your brand

Give us the domain name you want your mail to carry, the one that reads as you to every recipient.

We register it

We register a sending domain that matches your brand, separate from your website, so your main domain stays untouched.

We authenticate it

SPF, DKIM and DMARC go in automatically, correctly configured from the first message you send.

We watch it

If a record ever drifts, we notice and repair it. You see a status, never a task.

IN DETAIL

Three pieces, one finished domain

Here's what actually happens when we say your sending domain is handled.

BRAND-MATCHED

A domain built to carry your name, not ours

Your From address carries your brand's domain, not a shared one borrowed from an email tool. Recipients see your name and your domain together, the way they'd expect mail from you to look.

That domain is registered specifically for sending, separate from the one your website lives on. Your site's domain stays exactly as it is; your mail gets a domain of its own to build a reputation on.

  • Domain registered to match your brand

  • Separate from your website's domain

  • Add more sending domains as you grow

  • No shared or generic From address

AUTHENTICATION

SPF, DKIM and DMARC, done right the first time

SPF tells inbox providers which servers may send for your domain. DKIM signs every message so it can't be altered in transit. DMARC tells providers what to do if a message fails either check. Get one wrong and the other two can't save you.

We configure all three together, correctly, before your first campaign goes out. There's no partial setup to leave you exposed, and no record for you to approve, paste or troubleshoot.

  • SPF configured automatically

  • DKIM signs every message

  • DMARC policy set and enforced

  • All three live before you send

ONE DOMAIN, EVERYWHERE

Your links, your signature, your landing page: all one domain

The From address, the signature at the bottom of the email, every tracking link and the landing page it opens all live on the same sending domain, for every recipient. Nothing redirects through a domain that isn't yours.

That consistency matters to inbox providers and to the person reading your mail. A link that matches the sender reads as safe. A link that jumps to an unfamiliar domain reads as a reason to pause, or report.

  • From address matches your domain

  • Tracking links stay on your domain

  • Landing pages hosted on your domain

  • Nothing routes through a third party

WHAT IT MEANS FOR YOU

Set up once, trust it forever

Sending domains aren't a project you finish and forget. Here's what having yours handled actually buys you.

Inboxes, not spam folders

Correct authentication is the single biggest lever on whether mail lands in the inbox. Get SPF, DKIM and DMARC right, and inbox providers have no reason to send you anywhere else.

Your website's reputation, protected

Sending mail from a separate, authenticated domain keeps any delivery hiccup away from the domain your website and storefront depend on.

Zero DNS, ever

No registrar logins, no TXT records, no guessing which field takes which code. We do the setup, and we keep doing it.

Room to grow

Add more sending domains as your list and your sending volume grow, each one registered and authenticated the same way.

Watched, not worried about

If a record drifts or an authentication check starts failing, we notice and repair it before it ever touches a campaign.

COMPARED

What a typical platform leaves for you to fix

A typical email platform

  • Hand you a DNS guide and a login to your registrar
  • Leave SPF, DKIM and DMARC as separate, optional steps
  • Send tracking links through a shared, generic domain
  • Tell you to fix a failing record yourself
  • Make you choose between your website's domain and your mail

Kadexin

  • We register and host the domain. You never touch a DNS panel.
  • All three, done together. Authenticated correctly before your first send.
  • Every link stays on your domain. Reads as you, not as a stranger.
  • We notice drift and repair it. You see a status, never a task.
  • Your website stays untouched. Your sending domain does the sending.

QUESTIONS

Everything you're wondering about your domain

Answers to what people ask us before they switch their sending domain over.

Do I need to touch DNS?

No. We register, authenticate and host your sending domain for you. Your website's domain stays exactly as it is, untouched by anything we do.

Why not just send from my website's domain?

A separate, brand-matched sending domain protects your main domain's reputation and can share sending load across more than one domain as you grow, while every recipient still sees mail that reads as you.

What are SPF, DKIM and DMARC?

SPF lists which servers may send for your domain, DKIM signs each message so it can't be altered in transit, and DMARC tells inbox providers what to do if a message fails either check. We set up and enforce all three.

What happens if a record breaks?

We monitor every sending domain continuously. If a record drifts out of place, we notice and repair it ourselves. You'll see its status in your account; you won't get a task to fix.

Can I use more than one sending domain?

Yes. Add more sending domains as your business grows, each one registered and authenticated the same way, with no extra setup on your side.

Will my landing pages and links use the same domain?

Yes. Your From address, your signature, your tracking links and the landing page they open all sit on the same sending domain for every recipient.

Does this meet US email law?

Your sending domain is built for honest headers: a sender address and domain that are really yours. Pair that with a physical address and a working opt-out in every campaign, and you're meeting the CAN-SPAM Act's requirements.

How long does setup take?

You give us the domain name you want to send from. We handle registration, authentication and hosting; most domains are ready before you've finished designing your first campaign.
