Updated Review- Finally better!


I'm leaving my original reviews below but would like to update by saying the developer has finally fixed issues with crashing upon performing searches; which essentially rendered app useless. Somehow after an update bug is fixed. I must add that one of my co-workers uses this app as well, she has the same model iPhone as I do and same iOS version and she still experiences the issues I had before. But for me, this app is working perfectly once again.

This is an updated review. I used to love this app for several reasons. Unfortunately about a year ago, it started crashing when searching emails and contacts, replying to messages, opening/attaching documents. Despite several emails to support, the issue has never been fixed and it's making the app unusable. I just sent another email to support and their reply was "We hope to have this issue fixed eventually". Thats a less than ideal and desirable reply, especially for an app that costs $5. I'm not sure why apple and/or the developer still have this app in the app store. Don't waste your time and your patience with this.

Work Life Saver!


I just can't say enough good things about this app! Made it possible for me to be fully accessible to work when remote, in spite of my company's extremely intrusive security measures around bring your own device - requiring that I essentially turnover full access to everything on my personal phone, just to be able to access company email within my phone's native email application. I've tried other apps, which are little more than a web browser accessing Outlook webmail, and incredibly frustrating and tedious to use. This app is the closest to using your phone's native email application as you can get, is in full compliance with all of our security policies and procedures, and yet doesn't require me to install their privacy and personal security violating software. I'm a huge fan!

The best email app for business


I'm using this application recently and I have found it very useful. I do get emails constantly and I'm always on the go. I haven't found any email application with the same futures that this application has I do really like the fact that I can:

1. Change the font
2. Change the colour
3. Bullet points (Numbers or points)
4. Underline letters
5. Bold letters
6. Easy readable calendar
7. Emails are organised and easy to read

There are more options as well on this application which is really very useful for those whom are constantly on work email.

I always had to go back my laptop if I want to respond on an email where by I have to use a different colour in my response or if I want to change the font. Now I don't need to carry my laptop anymore 🎊😃🎊I have mail plus on my iPhone.

It worth every $ I paid. They have a very good customer service as well. Every time I asked for assistant it didn't take long to get back to me on. Few of my colleagues at work liked the application after I showed them what it can do and they downloaded it as well and started using it.

In short this application to me is No.1 in the market and it made my life easier as I'm a person who constantly get work emails.
