The user friendly UI of messenger is very good to handle any kind of requirement related to marketing or sales process in real time manner without much delay. It helps me deliver my message from inbox which was not possible earlier due to lack of proper knowledge about this product. I am able to share files easily by sending it as attachment within few seconds only. In case we are having more than 1 person working together then sharing data becomes difficult but still there's no option available like that too. So overall its pretty simple yet easy to use application if used properly and trained well enough could be helpful in some cases. If you have limited access to internet while using mobile network so better go with desktop version since they offer all features including video call capability through their website itself. For Marketing team managing multiple campaigns at once would help us track them effectively and also provide.
