The best email hosting for a small business gives every staff member a professional address on your own domain, gets messages into customers’ inboxes, filters spam and malware, and protects logins with two-factor authentication, at a total cost that still makes sense as the team grows. Before comparing brands, decide whether you need email only or a full office suite with documents and video calls, because that choice changes the price more than anything else.
This is Tremhost’s own blog, and Tremhost is one of the providers listed. Facts about other providers come only from their own websites, the shortlist is in alphabetical order and there is no ranking or winner.
What makes email hosting good for a small business?
Deliverability: SPF, DKIM and DMARC
What to check: whether the provider sets up, or clearly explains, SPF, DKIM and DMARC records for your domain. Why it matters: SPF lists the servers allowed to send for your domain, DKIM signs each message, and DMARC tells receiving servers what to do with messages that fail. Without them, your invoices and quotes are more likely to land in spam, and criminals find it easier to send fake emails in your name.
Spam and virus filtering
What to check: inbound filtering for spam, phishing and malicious attachments. Why it matters: one opened fake invoice can cost more than years of email hosting.
Account security
What to check: two-factor authentication on mailbox logins and the ability to reset or disable an account quickly. Why it matters: stolen passwords are a common route into business email, and 2FA means a password alone is not enough.
Pricing model: per user or per plan
What to check: whether you pay for each mailbox, or one price for a pool of mailboxes and storage. Why it matters: per-user pricing grows with every hire and every shared address such as sales@ or accounts@. Pooled plans cost the same whether you have 5 mailboxes or 50, but storage is shared.
Storage and attachments
What to check: storage per mailbox or per plan, archive space and attachment size limits. Why it matters: teams that send quotations, scanned documents and photos fill mailboxes faster than they expect.
Access and support
What to check: webmail, IMAP and SMTP for phones and Outlook, support hours, the billing currency and payment methods. Why it matters: staff need email on every device, and a failed card payment can suspend every mailbox at once.

- Microsoft Exchange Online (Plan 1). $4.00 per user a month, paid yearly on an annual subscription, with 50 GB of mailbox storage and 50 GB of archive storage per user, as listed on 5 November 2026. Suits businesses that rely on Outlook and want email without the full Microsoft 365 suite.
- Tremhost business email. Priced per plan, not per user. SME is $5 a month or $60 a year for up to 50 mailboxes and 75 GB in total; Corporate Plus is $10 a month or $120 a year for up to 500 mailboxes and 1,000 GB; Supreme is $15 a month or $180 a year for up to 1,000 mailboxes.

Suits Zimbabwean teams that need many addresses without per-user fees.
- Zoho Mail. Mail Lite is US$1 per user a month for 5 GB, or US$1.25 for 10 GB, and Mail Premium is US$4 per user a month with 50 GB of mail storage per user, billed annually at default US pricing, as listed on 5 November 2026. The page lists different prices for Africa and some other regions. Suits small teams that want low per-user prices.
A worked cost example: a team of 10
Using the published prices above, ten mailboxes for a year cost about $480 on Exchange Online Plan 1 ($4 x 10 users x 12 months), about $120 on Zoho Mail Lite 5 GB at default US pricing ($1 x 10 x 12), and $60 on Tremhost’s SME plan, which covers up to 50 mailboxes. The comparison is not like for like: Exchange gives each user 50 GB and the Microsoft ecosystem, Zoho Lite gives each user 5 GB, and Tremhost’s 75 GB is shared across all mailboxes. Decide what storage and features you need first, then compare the price for that.
Which email hosting should you choose? A decision guide
- You need documents, calendars and video calls in one suite: compare Google Workspace and Microsoft 365 plans, not email-only plans.
- You need email only for a growing team: a pooled plan avoids paying again for every new address.
- Your staff live in Outlook: any provider with IMAP works, but Exchange gives the fullest Outlook features.
- You also need a website: Tremhost’s web hosting plans include unlimited email accounts on your domain, which may be enough on its own.
- You pay locally in Zimbabwe: check that renewals can be paid by EcoCash or ZimSwitch so mail is never suspended over a declined card.
Frequently asked questions
Do I need my own domain for business email?
Yes. Business email runs on a domain you own, such as yourbusiness.co.zw. If you do not have one yet, read what a domain name is.
Why do my business emails go to spam?
Usually because SPF, DKIM or DMARC are missing or wrong, or because the content looks like spam. The Help Centre explains how to fix emails going to spam.
Can I move email to a new provider without losing messages?
Yes. Mailboxes can be copied over IMAP before the MX records are changed, so old messages and folders come across and new mail is not lost.
Can staff use business email on their phones?
Yes. Any IMAP and SMTP service works with the built-in mail apps on Android and iPhone. See how to set up email on your phone.
