Any good alternatives to Google app for work?

Rackspace offers email hosting for $2/user/month if you're not looking for the other features from Google. https://www.rackspace.com/en-us/email-hosting

My emails are managed with google app for work, however I feel it's expensive any other options ?

I just started using Zoho Mail a few weeks ago. So far so good.

I like Fastmail as an email provider.

Other than that I like Skype and Office 365.
