I've opened many tickets with Flare Hosting about our emails being bounced back to us. We've received no help from them. They said that they worked on it and the issues should clear up in 48 hours. I'm running a business and having reliable email service is important. It's been 6 days and nothing. On top of that, they have "who cares" type attitude. I keep opening up trouble tickets and get nothing but a sarcastic email from their tech support.
If you value your business and your email is an important tool, then do not risk it with Flare Hosting.
I do not recommend them and am actively searching for a new web host.
