I like that it has helped me to reduce marketing cost since we started using voucherfy as our promotional tool because of its unique features such are : - We have more reachable audience than any other traditional methods.- Easy integration into CMS or Email Marketing system so you don't need separate software tools anymore! The only thing which can be improved about this product would probably come from their support team when they ask questions during implementation process but overall everything's good :) Have experience working within eCommerce industry before implementing these kinds feature through email campaigns/website offer codes etc., therefore able understand how difficult was getting things done previously without online solutions available now at affordable prices (cheaper options).
