Eight providers, all reliable, compared on what actually differs. What they charge, how the price grows with your team, how much of the setup they do for you, and what comes in the box. We make one of them, and we say so.
The short answer
For one person, Zoho Mail at $1 a month is the cheapest reliable mailbox and Fastmail is the nicest. For a business with more than a handful of addresses, a flat-price host wins on cost every year you exist: Faivelo is $6 a month for unlimited mailboxes. If you need Docs or Teams, Google Workspace and Microsoft 365 are worth their per-user price. If encryption is a requirement, Proton. Everything below is the evidence.

FAQs
Which business email provider is cheapest?
For a single mailbox, Zoho Mail Lite at $1 a month. For anything beyond about five mailboxes, a flat-price host: Faivelo is $6 a month for unlimited mailboxes, which is less than one Google Workspace seat.
Are there free business email providers?
Zoho Mail has a free plan with up to five mailboxes on your domain, app and web only. Faivelo forwards unlimited addresses on your domain for free and gives 14 days of full mailboxes without a card. Everything else is a paid trial. The domain itself always costs money.
What is the most used email provider for business?
Google Workspace and Microsoft 365 dominate by seat count, largely because they bundle office suites. Among businesses that only need email, the market is far more spread across Zoho, Fastmail, Proton, hosting add-ons like Titan, and flat-price hosts.
Which provider has the best deliverability?
Any provider with SPF, DKIM and DMARC correctly configured delivers well; Google and Microsoft have the largest reputations, but the records matter more than the brand. The practical difference is who configures them. Faivelo does it automatically; most others hand you the records.
Can I move my existing email to a new provider?
Yes. All eight support IMAP migration, which copies your folders from the old account. Faivelo has the tool built in; Google and Microsoft have migration wizards; the others rely on third-party tools or your mail client.
Do I need Google Workspace to use Gmail for business?
To have Gmail at your own domain, yes. You can also keep a free Gmail account and read a business mailbox from another provider inside it over IMAP, sending as the business address.
Is per-user pricing ever the better deal?
For one person, usually. Zoho, Neo, Titan and Fastmail all cost less than $6 for a single mailbox. It stops being the better deal the moment you add hello@ or a second person.
What security features should a business email provider have?
TLS in transit, encryption at rest, two-factor authentication, spam and malware filtering, and support for SPF, DKIM and DMARC on your domain. All eight here have those. Only Proton adds end-to-end encryption.
