Maybe the dev can answer a couple of questions for me. My experience has been quite different. Over the last couple of days I have been trying to get my email notifications to work properly. I have the app set up to check for email every 5 minutes. I was a bit confused by the sleep setting on the application but when I noticed that I would not receive any new mail notifications for hours some times, I changed the sleep setting to awake every 15 minutes and sent myself two test emails in a row. The first showed up after 1/2 hour but only after I woke the phone up manually, and I was still waiting for the second to come in after an hour. I then changed the setting to prevent sleeping. At that point I received an email after about 10 minutes.
Does the sleep function work properly? Do you have to have it set to prevent to receive email in a timely fashion?
This app is very well though out. I really like the way the spell checker was integrated in to the application. That alone makes it valuable for sending business email. Sending an email with spelling errors could be very costly. If I can figure out where my mail alert/checking issues are coming from and find out that it is from an improper setting then it gets my two thumbs up and I think would be worth every penny.
