The best thing about this software tool that I like most at first sight was its user interface which looks simple yet very effective with all needed features included as well as being able to customize them according to our needs or requirements without any difficulty. This software tool also has an option where one could easily track subscription status of emails sent through their system so we know exactly what’s going around there (whether opened/read etc.). There are some minor glitches here but nothing too serious since they have been working hard to improve these problems over the past few months by issuing patches and doing other such things. Overall great product! It's really helping us manage subscriptions better. We've realized more subscribers who open newsletters right away after receiving notifications from PushNami compared to those who don't receive email notifications at once even when subscribed via newsletter signup forms directly. I love that we are able use our own templates as well! The best part about this product has been how user friendly they have made their system by allowing us so many different options when creating campaigns/notifications etc.. There really isn't anything i dislike at all with them but if there was something specific then maybe its not being updated or improved upon enough? We haven’t had any issues since using PNAMi thus far which makes me feel like everything works great together!!
