Every business-email provider publishes a per-user price, and that number is nearly meaningless until you multiply it by your mailbox count. The real question is: what does my setup cost at 5, 15, or 50 mailboxes? That's the number that decides which product fits — so we compare on that basis, with prices verified from each vendor's own pricing pages in November 2026.
Google's Business tiers (verified pricing, workspace.google.com/pricing, Nov 2026): Business Starter $7/user/mo, Standard $14, Plus $22 on annual commitment ($8.40 / $16.80 / $26.40 month-to-month). 14-day trial. You get Gmail on your domain plus the full Docs/Sheets/Meet/Drive suite. The price is the product: unbeatable collaboration depth, but the bill is mailbox × $7 — and it doesn't drop as you grow.
What that means in practice: a 5-mailbox company pays ~$35/mo, a 20-mailbox agency ~$140/mo, just for email-plus-docs. If your business runs on shared Google Docs, the premium buys real workflow — for everyone else it's the most expensive way to get a @yourdomain address.
Zoho's pricing (zoho.com/mail/zohomail-pricing.html, verified Nov 2026): Mail Lite $1/user/mo (5 GB, annual billing only; 10 GB $1.25), Mail Premium $4/user/mo (50 GB), Workplace Standard $3/user/mo annual ($4 monthly, adds docs/files/chat/meetings), Professional $6/$7. There's also a free plan for up to 5 users on one domain — webmail only, no IMAP/POP.
At the bottom end Zoho is unbeatable: a 5-mailbox company pays ~$5/mo (Mail Lite, annual billing). A 20-mailbox agency pays ~$20/mo. The caveats: the cheapest useful tiers are annual-only, the interface is a step behind Google's polish, and if you need the collaboration suite the price creeps back up to $3–6/user.
TrekMail (ClickBank product trekmail; TrekGuider Inc., Delaware corp, EU-hosted) flips the model: flat per-account pricing with capped limits instead of per-seat fees. Starter $5/mo (ClickBank offer) — or ~$3.50/mo equivalent ($42/yr) on the vendor's own site — covers 50 domains and 100 users per domain, 15 GB, 6,000 emails/day. Pro $10/mo: 100 domains, 300 users/domain, 50 GB, 15,000/day. Agency $29/mo: 1,000 domains, 1,000 users/domain, 200 GB. A free Nano tier (10 domains, BYO SMTP) exists on the vendor site.
Includes standard business-email infrastructure: webmail with calendar and contacts, IMAP/SMTP/CalDAV/CardDAV (works with Outlook, Apple Mail, Thunderbird), aliases, forwarding, catch-all, migration from Gmail/Outlook/IMAP, managed SPF/DKIM/DMARC/MTA-STS, Cloud Drive, an email verifier, and a REST API with AI-agent (MCP) tooling.
| Scenario | Google Workspace | Zoho Mail | TrekMail |
|---|---|---|---|
| 5 mailboxes, 1 domain | ~$35/mo (Starter, annual) | ~$5/mo (Mail Lite 5 GB, annual) | $5/mo flat (Starter) |
| 20 mailboxes, 6 client domains | ~$140/mo | ~$20/mo (Mail Lite) | $5–10/mo flat (Starter covers 50 domains) |
| 50 mailboxes, 30 domains (agency) | ~$350/mo | ~$50/mo (Mail Lite) | $10/mo flat (Pro: 100 domains, 300 users) |
| Deliverability setup (SPF/DKIM/DMARC) | Managed (guided DNS) | Managed (guided DNS) | Managed (SPF/DKIM/DMARC/MTA-STS) |
| Offline apps & deep collaboration | Docs/Sheets/Meet/Drive — strongest | Workplace suite at $3+/user | Email + Cloud Drive only; no doc suite |
Prices verified 2026-11-05 from each vendor's pricing page (Google: workspace.google.com/pricing + Google Help Center; Zoho: zoho.com/mail/zohomail-pricing.html; TrekMail: ClickBank listing, live hop test 307 → trekmail.net/cb, plus vendor plans page).

The cheapest business email is the one whose model matches your mailbox count. Fixed small team → Zoho ($1/user) or TrekMail ($5 flat) tie around $5/mo for 5 mailboxes. Growing multi-domain operation → TrekMail's flat pricing wins outright, and only TrekMail of the three is a flat per-account product. Google Workspace is the premium collaboration pick and the most expensive way to send email — choose it for the suite, not the address. We have not used TrekMail in production ourselves; this is a pricing-and-fit comparison from verified public data, not a claim of results.
