Our verdict on Testi@

Testi@ is an email testing service for developers and email teams that need to preview HTML messages across desktop, mobile, and web email clients. It generates screenshot previews, supports HTML editing and local template testing, and includes spam testing for common pre-send checks. Browser-based previews, rendered HTML source inspection, and a Chrome extension extend testing beyond a single editor or workflow.

The product follows a freemium model with a free plan and a four-day free trial. Its paid testing plan includes email previews across supported clients and unlimited email previews. The plan structure is straightforward for teams focused on repeated rendering checks, while email service provider integration, Sublime Text, Atom, and the Chrome extension support different production workflows. The published plan details emphasize preview volume and client coverage rather than a larger suite of automation or quality controls.

Testi@ is strongest when the main requirement is visual email review across desktop, mobile, and webmail environments, supported by spam testing and live testing through Chrome. It also offers local HTML template testing and rendered source inspection for teams that need to investigate markup after a preview. Teams seeking API-driven automation, accessibility checks, or link validation should choose a product with those capabilities instead. Testi@ fits developers and email teams that want a focused browser-based testing service with an accessible entry point, but it is less suitable for organizations requiring a broader automated email quality-assurance platform.
