ABOUT KADEXIN
We built an email empire so you don't have to.
Kadexin started with one plain idea: every business deserves campaigns that land in the inbox, not the spam folder, without hiring a legion to run them. Build it yourself with a simple editor and AI that writes in your voice, or hand us the reins and we run it for you.
Every address checked before you send
Your own sending domain, set up for you
Month to month, no contracts
WHY WE EXIST
Every business deserves an email programme worthy of an empire.
Kadexin began with a frustration we knew firsthand: email tools built for marketing departments ten people deep, sold to business owners running the whole show alone, nights and weekends included.
The moment that decided it was watching a café owner spend a Sunday night wrestling with DNS records just to get her newsletter past spam and into someone's actual inbox. She didn't need a lecture on authentication. She needed someone to just handle it. So now we do, for everyone who signs up.
Today Kadexin serves small business owners, growing online stores, local service businesses and the agencies running campaigns for all of them. Different businesses, same complaint: too many tools, too much jargon, not enough results you can actually see.
You can build every campaign yourself, with a drag-and-drop editor and AI that writes in your voice. Or you can hand us the reins: our team plans, writes, designs and sends your campaigns for you, month to month, done-for-you from $399. Either way, the domain is yours, the list is yours, and the reporting tells you the truth about both.
WHAT WE BELIEVE
Run your campaigns like a general, not a gambler.
These aren't values on a poster. They're the reasons the product works the way it does.
Your inbox reputation is sacred
We treat your sending reputation the way a quartermaster treats the supply lines: check everything, protect it fiercely, never risk it for a shortcut.
Every address gets verified at the mailbox before it enters a campaign, and every domain earns its sending volume gradually instead of being thrown at the inbox all at once.
Plain pricing, no fine print scrolls
Five self-serve plans, priced in US dollars, month to month. No contracts, no setup fees, no surprise invoice arriving by courier.
Every feature, every plan
The AI writer, the verification, the domain setup and the reporting travel with every plan, from the smallest up. We don't ration the good stuff.
Small business owners first
We build for the person running sales, support and marketing before breakfast, not a department with a budget line for growth tools.
Generous, not stingy
Like a good host, we'd rather over-deliver. If a feature should be included, it's included, never held back as an upsell.
MEET THE MASCOT
Say hello to Maximus.
Maximus is a centurion who traded his sword for a stylus. He doesn't march on cities, he marches your campaigns past spam filters and into the inboxes where they belong.
He's the one standing guard over your sending domain, checking every address before you send, and throwing a small parade (fewer trumpets, more confetti) every time a campaign lands.
You'll see him dressed for the job throughout the site: hopping into hero sections, relaxing when our team runs your campaigns, magnifying glass out while double-checking your list. He takes the work seriously. Himself, less so.

Real answers, from real people, by email.
Email us any time. A real person reads every message, not a script, and you'll hear back from someone who actually knows what a sending domain is.
If you'd rather not run campaigns yourself, our team plans, writes, designs and sends them for you, done-for-you campaigns from $399 a month, month to month like everything else we do.
Every campaign you send through Kadexin carries honest headers, a real subject line and your physical address, and opt-outs are honored well within the ten business days the CAN-SPAM Act allows. Compliance isn't a feature you configure. It's just how we built the place.
Your empire starts with one campaign.
Set up in minutes, send from a domain that's ready, and never sign a contract to do it.
