How I built a drag-and-drop email product with Gemini AI generation, Outlook-safe HTML, quality scoring, SMTP campaigns, and tracking — from canvas edit to send.

Building Emailer Studio
Most email tools force a tradeoff.
Either you get a pretty builder that exports broken HTML…
or you get “safe” templates that look like 2012.
I wanted both: a modern canvas experience **and** production-ready output that survives Outlook and Gmail.
That product became **Emailer Studio**.

The problem
Building marketing emails is still painful:

What Emailer Studio does
1. Drag-and-drop email builder
A visual canvas with reusable blocks so users can compose emails quickly without fighting raw HTML.
2. Production-safe HTML output
The hard part isn’t designing. It’s exporting markup that still renders correctly in real clients — especially Outlook.
3. Gemini AI generation
Users can generate drafts and iterate faster instead of starting from a blank page.
4. Quality scoring
Before send, the product checks whether the email is actually in good shape — so weak layouts and weak content get caught earlier.
5. Campaign sending + tracking
SMTP campaigns with open/click tracking, so creation and delivery are not disconnected workflows.

That makes it feel like a product, not a component demo.

What I learned
Shipping an email product teaches you quickly that frontend polish is only half the job.
You also need:
The best builders don’t just look modern.
They help someone go from idea → send with confidence.
