The problem

HTML email looks simple.
It's harder than you think.

HTML email still follows "old rules" from the 1990s. "Modern" code built for web pages doesn't work here. Build it the usual way, and it will break. CodingDoGG™ automatically writes code that follows those old rules,so you get beautiful HTML email that stays intact.

No HTML skills
required

Just set text and images, and adjust colors and shapes.
Build the beautiful design you imagine —
freely and easily.

then send

Features

Pick a template,
then polish it beautifully

Display breaks from HTML email's quirky rules?
CodingDoGG™ optimizes and assembles the HTML for you. You focus on the design in front of you, and get the beautiful newsletter HTML you pictured.

No-code, intuitive design

No tags, no code
design freely, intuitively

Even if HTML intimidates you, or a broken layout once made you quit — you're fine. Leave the hard parts to us. Arrange blocks, place images, type text, adjust colors and shapes. Any design comes together beautifully, exactly how you want.

WYSIWYG editing

Text and images
edited exactly as you see them

Headlines, body copy, photos, buttons — build while seeing the finished layout on screen. No code writing or HTML expertise required.

Email quirks handled

Email HTML optimized
for every environment

Email has its own old rules where "normal" web code doesn't work, and every client renders differently. CodingDoGG™ adjusts for these automatically. Your message lands with the same impression everywhere.

One-click export

Copy finished HTML
to your delivery system

Copy finished HTML with one button. Paste it into the system you already use and send as usual. Before going live, send a test to yourself to check for broken layouts.

Why a hands-on editor

Why finish it by hand,
even in the AI era

AI is easy and convenient. But to finish exactly your way and send with confidence,doing it yourself is faster and more reliable.

01

AI is a gamble
the UI is precise

Ask AI to "darken the image a bit" or "tighten the margin by 5px" and something else breaks — an endless "AI gamble." By contrast, with a UI where you drag a slider and fine-tune to the millimeter on the spot, you get exactly the look you want — faster.

02

AI struggles with
email's old rules

AI handles modern web code well, but struggles with email constraints like the 998-byte line limit and Outlook's nested tables. AI-written code may look clean yet break badly on the recipient's side. CodingDoGG™ builds break-resistant HTML that holds up across many email environments.

03

The joy of craft
is uniquely human

The more you refine the details — photos, wording, colors, spacing — the more polished your newsletter becomes. Leave it all to AI and those fine adjustments no longer work. CodingDoGG™ handles only the tedious code, so you're free to fine-tune every detail yourself.

From the founder

Koki Iino

CEO, Imagenation Inc.

In 2026, HTML email still delivers ROI.
From effective promos to lean in-house production.

For years I've worked on the front lines of corporate marketing and PR.
In-house staff should reach customers quickly and flexibly — on their own. But in reality, you couldn't run things without specialist knowledge, including code.

If there were a tool that let staff create web promo materials freely — without coding or specialist knowledge — teams could move faster. If it didn't exist, we'd build it. That's how "CodingDoGG™" was born.

CodingDoGG™ aims to bring HTML email, web pages, and similar code-heavy promos in-house. When in-house staff can run campaigns on a planned schedule — without losing quality, speed, or flexibility — it reduces agency reliance and cost, and enables unified promo management.

FAQ

Frequently Asked Questions

Q. Are there any monthly fees?

No, none at all. It's a one-time purchase — pay once and use it for as long as you like.

Q. When will it be released?

We plan to release in September 2026. Join the waitlist and we'll notify you as soon as we launch.

Q. Will there be updates after I buy?

We keep the price affordable as a one-time purchase, so frequent paid updates aren't included. You can use the version you bought for a long time. Major new features may ship as a separate new version.

Q. How many computers can I use with one license?

One license covers one computer.

Q. Can I really get a refund?

Yes. If it doesn't run correctly within 14 days of purchase, contact us via the form and we'll process a full refund. We also review other circumstances case by case.

Q. Which OS is supported? (Windows / Mac)

Both Windows and Mac are supported. Install it on your computer and you're ready to go.

Q. Can staff who aren't tech-savvy use it?

Yes. The app handles tricky settings behind the scenes. All your staff do is pick blocks, type text, and place images. That's it.

Q. Could it break my current website?

Not at all. This is standalone software on your PC — it never touches your existing site's backend.

Q. Will HTML email break in Gmail or Outlook?

It's built to resist breaking. CodingDoGG™ generates code that follows each client's "old rules," so your emails render well in Gmail, Outlook, Apple Mail, and other clients.

See it for yourself. Download real newsletter HTML made with CodingDoGG™ for free, send a test to yourself from your own delivery system, and check the rendering quality in your inbox.

Q. Where are my newsletter HTML and images stored?

Everything stays on your computer. Drafts and images aren't stored on external servers — your data stays with you.

Q. How do images work? Do I need a server?

While editing, you use local images — no setup needed. For live sends, images must be hosted online, so you upload them to your delivery system or server (WordPress, your CDN, company server, Shopify, etc.). The app checks sync and outputs production HTML. We'll guide you step by step. (Test sends may temporarily use our server for verification only.)

Q. Can I send bulk email from this app?

Large bulk sends aren't supported — use your existing mail system for that (paste the HTML we export).
