Just for fun, we decided to release our drag and drop editor on which we were working for couple of years for our own email marketing platform (Ecomail.cz) in summer 2017, the new product is called TOPOL. Since we were working on the product for years and thousands of customers were already using it as part of Ecomail, the success was immediate.
Within its first month of being released, TOPOL got over 1000 new users and was at the top of Producthunt for many weeks.
After seeing the overwhelming interest in TOPOL, we decided to invest a lot more time and resources into it to upgrade it from a fun little side tool to a full-fledged product.
Once we added some customer-requested features, TOPOL is now one of the top-ranked email editors in the world and is used by thousands every week.
And best of all, we never stopped having fun: Predicting trends in email marketing and customer experience, offering an easy-to-use editor that lets anyone create professional-looking emails, and reacting to the needs of our customers are still our favorite things to do.
