From my experience with Letterly, I found it excels at simplifying the traditionally cumbersome process of sending physical letters by automating everything from personalization to mailing. The platform is particularly well-suited for businesses and marketers who want to run direct mail campaigns without managing printing or postage logistics. However, the lack of a mobile app and limited language support may restrict flexibility for some users. Overall, if you need reliable, automated personalized letter mailing integrated into your workflow, Letterly delivers a streamlined and efficient solution.
