Faivelo lets you create as many mailboxes on your domain as you like for one flat price, starting at $6 a month. "Unlimited" is a word that deserves a footnote, so here is every footnote, in plain language, before you sign up rather than after.
What unlimited means here
Every paid Faivelo plan lets you create any number of mailboxes and aliases on your domain, and the price does not change when you add one. The limits that do exist are on storage, domains, sending volume, and one safety stop. They are listed below with their numbers.
- Mailboxes and aliases: No limit on any paid plan
- Storage: Pooled per account: 10 GB, 200 GB, 1 TB or 2 TB by plan
- Domains: Three on Starter, unlimited from Growth
- Everyday mail: Not metered on paid plans
Storage is pooled, not per mailbox
The storage number on each plan is a pool for the whole account: Starter 10 GB, Growth 200 GB, Pro 1 TB, Business 2 TB. Twenty mailboxes on Starter share 10 GB between them, which is fine for a team that archives and tight for one that keeps every attachment forever. There is no per-mailbox price, so the right response to a full pool is a bigger plan, not fewer addresses.
In practice the pool is what makes unlimited honest. A host that offers unlimited mailboxes with a small fixed quota on each is quietly selling seats by another name; a shared pool lets a role address that gets three messages a year take up no room at all.
Domains: three on Starter, then no cap
Starter covers up to three domains, each with as many mailboxes as you like. Growth and above remove the cap on receiving domains entirely. If you run one business with one domain, Starter is the plan; if you look after client domains or a drawer of side projects, Growth is.
Sending domains are counted separately from receiving ones. Starter and Growth designate one domain to send from through the API and campaigns, Pro three, Business ten. Everyday mail from a mailbox is not affected by that count; it is about which domains your code and newsletters may send as.
Sending: unmetered for people, metered for machines
Mail you send from a mailbox, through webmail, Apple Mail, Outlook or a mailbox API key, carries no daily or hourly quota on paid plans. Send what your business sends. The one exception is a safety stop of 2,000 messages an hour per mailbox login, sized so that no person gets near it; it exists to halt a runaway script or a stolen password in the minutes before anyone notices.
Machine mail is metered, by plan and in separate budgets. Transactional API sends are 3,000 a month on Starter, 20,000 on Growth, 50,000 on Pro and 100,000 on Business, with a daily cap of a tenth of that. Campaigns start on Growth at 3,000 a month, Pro 25,000, Business 100,000. A newsletter can never use up the password-reset budget, because they are different pools.

The free plan has no mailboxes
Faivelo's free plan is forwarding only: unlimited aliases and a catch-all that pass mail on to an inbox you already have. It has no mailboxes, no webmail and no sending. We mention it here because "unlimited" on the free plan means unlimited aliases, not unlimited inboxes, and we would rather you knew before you tried to log in to one. The paid plans are where the mailboxes live, and the trial is fourteen days of Growth without a card.
What other "unlimited" offers tend to hide
When you compare, read for four things. A storage figure per mailbox rather than per account, which turns every new address into a cost in disk. An hourly or daily sending cap on ordinary mail, which a sales team hits on a busy afternoon. A domain count buried in a lower tier. And a "fair use" clause with no number attached, which means the limit is whatever support says it is on the day.
Every one of those is a legitimate thing for a host to limit. The problem is only when the word on the pricing page and the number in the terms disagree. The table above is our attempt to put both in the same place, and the comparison page lays the same numbers beside the per-seat providers.
Unlimited is a promise about the price. The limits are promises about everything else, and they should be written down too.
