Email Testing & QA Services

Make sure your emails work properly before they reach your audience. Our email testing service checks campaigns and templates across major email clients, devices and screen sizes to identify rendering, layout and usability issues before you hit send.

Catch email problems before your customers do

An email can look perfect in one inbox and completely different in another. Outlook, Gmail, Apple Mail and mobile devices can all interpret HTML differently, creating problems with layouts, fonts, imagery, spacing and calls to action.

Our email testing service checks your campaigns and templates across different environments to identify problems before launch. We review rendering, responsive behaviour, links, imagery and usability, helping you deliver a more consistent experience across inboxes and devices.

Why choose Email Squad for email testing & QA?

Email testing isn’t just about checking whether an email opens. Small rendering problems can affect how your campaign looks, how easy it is to understand and whether someone can actually interact with it.

We combine specialist email development knowledge with thorough testing across major email clients and devices. We’ll identify rendering and usability issues, explain what’s causing them and help get your email working properly before it reaches your audience.

Our step-by-step approach

Every great email starts with understanding. We get to know your brand, audience, goals and platform before production begins.
