What are the limits of Zoho Mail's free plan?

Zoho's Forever Free plan covers five users on a single domain with web access only — IMAP, POP and SMTP access are reserved for paid plans, so you cannot use a desktop mail client with it.

Is Omucloud a good Zoho Mail free alternative?

It is if your priority is free email on your own domain without a seat cap. Omucloud never charges per user, so no address you create today can be moved behind a seat charge later. The only paid option is extra attachment storage for a domain, and it adds room to what free already gives you rather than fencing any of it off. If a mailbox needs more than the free 500 MB, the domain can add pooled storage: Business, 100 GB for US$20 a month, or Scale, 1 TB for US$100 a month, shared by everyone on the domain and never charged per person. Beside per-seat pricing that is close to nothing — US$20 a month is what a suite charges for about two seats, and here it covers the whole company.

Where does Zoho beat Omucloud?

In breadth. Zoho offers native mobile apps, IMAP and SMTP access on paid plans, a full office suite, and commercial support. Omucloud deliberately does one thing: free, unlimited mailboxes on a domain you own.

Can I migrate from Zoho to Omucloud?

You can point your domain's MX, SPF and DKIM records at Omucloud and receive new mail immediately. Omucloud does not import existing archives, so keep your Zoho account until you no longer need the old mail.

Comparison with Zoho Mail Free

Five seats,or every address your domain needs.

Zoho Mail is the name that comes up first when people search for free email on a custom domain, and deservedly — the Forever Free plan is genuinely free and Zoho is a serious mail provider. It is also the free tier of a paid suite, which is where the five comes from.

Addresses on your own domain

Zoho Mail Forever Free

Five

Five users on one domain. The sixth needs a paid plan, and so does every one after it.

Omucloud

Unlimited

Every address on a verified domain is a real mailbox with its own inbox and password. There is no seat to count, and no tier above this one.

Try Omucloud freeNo credit card. Three DNS records. About three minutes.

The seat count

One of these has a sixth person problem.

Nobody leaves a free plan over a feature list. They leave when somebody joins, or when the domain needs one more address for a listing, a form or a robot.

Zoho Mail Forever Free

Five filled, and the rest of the row is a paid plan. The cost of your domain's addresses scales with how many hats a small team wears.

Omucloud

hello@, support@, billing@, privacy@, one per person and one per app you ship. Nobody counts seats, because there is no seat to count.

Side by side

Graded in three parts

The ember rule marks the product each row favours. It lands on both sides, because across these nine rows the answer genuinely goes both ways.

Scale and cost

The limit people actually hit.

Cost: OmucloudPermanently free, and never per user (the stronger of the two on this row); Zoho Forever FreeForever Free plan, with paid tiers above it
Email addresses: OmucloudUnlimited on your verified domain (the stronger of the two on this row); Zoho Forever Free5 users on Forever Free
Domains: OmucloudOne custom domain per account; Zoho Forever FreeOne domain on the free plan

How you reach your mail

Where Omucloud is the narrower product, and says so.

Send and receive on your domain: OmucloudYes, DKIM-signed; Zoho Forever FreeYes
IMAP / POP / SMTP access: OmucloudNot offered — Omucloud is a web app; Zoho Forever FreeWithheld on the free plan; paid plans only
Mobile apps: OmucloudWeb app, plus free iOS and Android apps — both new in September 2026; Zoho Forever FreeMature iOS and Android apps (the stronger of the two on this row)
Attachment limits: Omucloud25 MB per message — one file may use all of it — and 500 MB per account, kept until you delete them. Need more? Pooled storage for the whole domain from US$20 a month (100 GB), never per person — beside a per-seat bill, close to nothing.; Zoho Forever FreeMore generous, tiered by plan (the stronger of the two on this row)

Everything either side of mail

A suite against a single product.

Office suite: OmucloudMail and calendar invites only; Zoho Forever FreeDocs, Sheet, Show, Cliq and a large product suite (the stronger of the two on this row)
Support: OmucloudBest effort, no paid support tier; Zoho Forever FreePaid support available (the stronger of the two on this row)

Which one you should actually pick

Four reasons each, and the ones on the left are real. If any of them describes you, Zoho is the better answer and you should stop reading here.

Pick Zoho if

You want the whole suite

You need IMAP, POP or SMTP for a desktop client and will pay for a plan.
You want documents, spreadsheets and chat from the same vendor.
You want a support contract behind your mail.
Five addresses is genuinely all your domain will ever need.

Pick Omucloud if

You want the one thing, unlimited

You want email on your own domain permanently free, with no subscription and no card.
You do not want a seat cap deciding how many addresses your domain can have.
You want setup to be three steps and about three minutes, not an onboarding project.
You would rather have one product that does mail than a suite you use a tenth of.

If you are moving over

Three things to know before you touch DNS. None is difficult, and all three are easier to handle before the switch than after it — the setup guide has the records themselves and the panel path for each registrar.

Nothing is imported

Omucloud does not pull your existing archive across. Everything already sitting in Zoho stays in Zoho, so keep that account alive until you are sure you no longer need what is in it.

MX can only point at one place

The moment Omucloud's MX record wins, new mail stops arriving at Zoho. Publish the records when you are ready to switch, not while you are still evaluating.

Replace the SPF record, do not add one

A domain may publish only one SPF TXT record. Zoho's has to be merged with ours or removed — two of them is the single most common reason a migrated domain fails to verify.

Unlimited addresses on a domain you own, sending and receiving, permanently free. If you are still under five people, keep Zoho with our blessing — and keep this page for the day somebody joins.
