This is the most sluggish email client ever. Aside from being very sluggish to load up messages, I sent out two very important emails via this app, two emails that needed urgent attention. This useless app kept the emails on outbox for more than 24 hours. Then I updated. After updating it, till this moment, my emails wouldn't load up. Now I am at the verge of loosing something very important that has the potential of costing me huge amount of money. Disappointed!
