Business email:
compared by the size of your team.
Email at your own domain rather than a free provider's. And the providers do not bill the same way — which on its own flips the comparison between one person and a team of five.
Check your hosting first, then look at Zoho's free plan.
Many hosting plans include business email at no extra cost, so what you are shopping for may already be in your account. If it is not, Zoho Mail's free plan covers up to five users — with one published limitation we explain in the guide. Beyond that, the billing model decides it: per user, or per mailbox.
If you read nothing else.
No email before the domain
Professional email is built on your domain. If you do not have one, that is your previous step.
"Per mailbox" is not "per user"
A price that looks cheapest for one person can be the dearest for a team of five. Do the sum for your team.
Role addresses are aliases, not mailboxes
info@ and support@ are normally free forwarding aliases. Do not buy a mailbox for each.
Whoever controls the registration email controls your domain.
That is not a detail: a domain follows whoever holds the registration email, not whoever paid for it. We have the right way to register.
