While Glimmernet is very active in web hosting, we stopped offering traditional email hosting a few years ago because there are just too many providers out there that can do it more reliably, at a lower cost, and offer dedicated support for email hosting. We usually recommend Microsoft 365 or G Suite as reliable options that give you full functionality for email, calendaring, file sharing, and more. (Glimmernet is a Microsoft partner.)
You can get Microsoft 365 (formerly called Office 365) for as little as $5/user/month at https://www.microsoft.com/en-us/microsoft-365/business/compare-all-microsoft-365-business-products?&activetab=tab:primaryr2 or Google G Suite for as little as $6/user/month at https://gsuite.google.com/pricing.html
There are another of other email providers as well, but these are two that are easy to use and have a good integration with desktop and mobile devices on multiple operating systems.
If you decide to sign up with one of these providers, we can help you with making sure that the DNS entries are correct to make sure that your email is delivered properly and does not get flagged as spam.
And if you decide to go with Microsoft 365, let us know and we’ll help you enter our partner ID so that we can best assist you with your integration!
