digitalexpanse I have some clients who use other solutions like Google Workspace, Titan Mail and other 3rd party solutions, but there are some of them who are not willing to pay or don't have the knowledge to set it up.
Considering that my main business is agency/web development work (I don't offer hosting openly), I can still manage this way, it's more of a 1 to 1 relationship with clients.
But even if I refer them to workspace, zoho and others, they would still like to channel all payments and support through me, so it would be an automation nightmare as my current billing system doesn't integrate with these services and I would end up managing them manually. From this perspective, Enhance email offers me functionality and automation.
That's just my particular case, I think many companies here don't offer email at all (from what I can gather from the posts).
