I have over 25 years experience in messaging from setting up complete enterprise environments to support and troubleshooting. This client is ok. It's missing some common email client options like calendaring for example. A complete email package for business users needs calendaring. Relying on the built in Android and Apple calendar is not the same. Encrypted message support would be a great option as well. Over all, it works.

Best client for anyone running their own mailserver on their Synology device. I've tried many other clients before, but many try to be "smart" for me with their annoying "smart inboxes" or "focus areas". Please keep this client as it is, clear and simple. I can perfectly think and organise myself. I love how mail and calendar are in one app. My only wish is that it would also have a contacts section that connects to the contacts on my Synology.

Nice app and picks up e-mails nicely from my server at home. However, my phone does not vibrate on receiving a mail notification. I've checked the settings and cannot find anything that will allow this. If the phone vibrated on receiving e-mail notification then my Gear S3 would in turn vibrate. **Update 2020 - been using this for a long time now and my watch received notifications. Works perfectly and keeps email under my control.
