I have a potential client who wants to know, if I build a website for him using Webflow, have it hosted by Webflow, if it will be possible to have his email go to his websites domain like this:
Well you could use namecheap to register your client’s domain name and use their native email hosting so that you have everything from domain name DNS settings to webmail and aliases centralized in one platform. Webflow indeed do not provide such services (so far I know).
@anthonysalamin is correct in his statement.
Webflow does not offer Email hosting support. You could use Namecheap or GoDaddy for your domain name hosting provider and then host the emails yourself or us something like Outlook or GSuite for your emails.
