Hi guys!
Hopefully this is the right place to ask about this.
What are you using to provide an inbox to your end-users for your Trellis based project? To provide them with an inbox te send and receive e-mail.
I’m used to setting up G Suite to provide an inbox for clients with their own domain. I look forward to hearing what you’re using!
My clients all have existing enterprise email solutions in place, like G Suite, Office365, or on-premise Exchange, so I’m not usually in the position to have to recommend or set one up.
My recommendation, though, is to go with a solution with good technical support, so that you’re not always on the hook for fixing it when it breaks. Office365 has great support and great reliability.
Great to hear, thanks 
I agree. Having ~40 users can drive up costs for the enterprise solutions however.
A business with ~40 users should take their email seriously enough to pay for a proper enterprise solution.
