Reviewers mostly praise Designmodo, especially its Postcards builder, for being fast, simple, and easy to learn while still producing polished, clean HTML email templates. Users say the templates look strong, editing is smooth, exports are painless, and the tool works well for marketers, designers, and developers alike. Customer service also gets positive mention. The main criticism is value for money: one reviewer says pricing feels hard to justify for small businesses with light email needs, and another notes some customization limits and possible design fatigue.
