HubSpot Newsletter Builder

Designing a scalable newsletter creation system for non-technical editors.

A custom internal tool built to help editors create HubSpot-compatible newsletters without touching code — while maintaining design consistency and reducing production errors.

Overview

The editorial team regularly publishes newsletters through HubSpot. However, HubSpot's email editor introduces several challenges:

Limited design flexibility
Large and complex email structures
Strict formatting limitations
Frequent template breakages
Inconsistent outputs caused by manual editing

Many editors are not familiar with HTML email development, resulting in broken layouts, inconsistent branding, and time-consuming fixes.

The Problem

Limited HubSpot Editing Experience

The native editor offers limited flexibility and can be difficult to manage for large newsletter structures.

Template Breakage

Editors frequently modify layouts and unintentionally break newsletter templates.

Design Inconsistency

Visual quality varies depending on who creates the newsletter.

Production Bottlenecks

Design and development teams spend time fixing issues instead of creating content.

HubSpot — the platform newsletters are ultimately sent from.

HubSpot's native email editor — the constrained environment editors had to work in directly.

The Solution

Instead of forcing editors to work directly inside HubSpot, I designed a custom newsletter builder that generates HubSpot-compatible code automatically. Editors build newsletters using a structured visual interface while the system generates production-ready code in the background.

No coding knowledge required
Consistent design system
Faster newsletter production
Reduced template errors
Scalable workflow
