The best free custom domain email services at a glance
Zoho Mail is the only service in this guide with a genuinely free plan that supports a custom domain, covering up to five users on one domain. Its free tier is web-only, with no IMAP access. If you need a desktop mail app, Migadu at 19 dollars a year is the cheapest realistic pick.
Most guides blur the line between a free plan and a free trial. Proton Mail, Tuta Mail, Fastmail and Google Workspace all have free or trial options, but none lets you send from your own domain without paying. A 30 day trial is not a free plan. You also need to own the domain itself, which usually costs about 10 to 15 dollars a year.
Key takeaways
- Zoho Mail is the only service here with a free tier that supports a custom domain, for up to five users on one domain with 5 GB each.
- Proton Mail and Tuta Mail have free plans, but neither allows a custom domain until you pay.
- The cheapest paid route is Namecheap Private Email at 14.88 dollars a year, or Migadu at 19 dollars a year.
- Fastmail and Google Workspace have no free plan, but they lead on polished apps and office suites.
- Budget about 10 to 15 dollars a year on top of these prices for the domain name itself.
How we picked
We picked live services that accept new signups and support email on a domain you own. Every website listed here was checked and loads as of 14 Nov 2026. We read each vendor pricing page or a recent third party check of it, and recorded whether custom domains work on the free tier or only on a paid plan. Prices below are third party reported, checked 14 Nov 2026. We weighted the free tier first, then the cheapest paid plan that adds a domain, then storage and IMAP access. We left out Skiff, which shut down.

Is there really a free email service for a custom domain?
Yes, but only one service in this guide qualifies. Zoho Mail has a Forever Free plan that hosts one custom domain for up to five users, with 5 GB of storage per user. That is a real free plan, not a trial. Proton Mail and Tuta Mail both have free plans, but both restrict you to an address on their own domain, such as proton.me or tuta.com, until you upgrade. Fastmail, Google Workspace, Migadu, MXroute and Namecheap Private Email have no permanent free plan, though some offer a 14 or 30 day trial.
What does a free custom domain email plan leave out?
A free plan almost always leaves out something you will notice. Zoho Mail free excludes IMAP, POP and ActiveSync, so you cannot connect Outlook, Apple Mail or Thunderbird. You read and send mail through Zoho webmail or the mobile app only. The free plan is also available only in select data centers, and Zoho does not publish which ones. Proton Mail free caps storage at 1 GB, allows one address, and limits you to 150 messages a day, with no custom domain and no IMAP. Tuta Mail free gives 1 GB, one calendar and three labels, with no aliases, no custom domain and no inbox rules.
How much should I expect to pay for custom domain email?
For one person with one domain, expect between zero and about 60 dollars a year. Zoho Mail costs nothing for up to five users if you accept web only access. Namecheap Private Email costs 14.88 dollars a year for one mailbox, Migadu costs 19 dollars a year for unlimited addresses, and Fastmail costs 60 dollars a year. A small team pays per user on most services, so five people cost about 60 dollars a year on Zoho Mail Lite, or 420 dollars a year on Google Workspace. Flat rate hosts such as Migadu and MXroute charge per account instead of per user, which is why they stay cheap as you add addresses.
Do I need IMAP, or is webmail enough?
Webmail is enough if you are happy reading mail in a browser tab or the provider mobile app, and if you only use one device most of the time. IMAP matters when you want the same inbox in Outlook, Apple Mail, Thunderbird or a phone mail app, with sent mail and folders synced everywhere. Zoho Mail free, Proton Mail free and Tuta Mail free all lack IMAP, so they lock you into the provider own apps. Every paid plan in this guide except Tuta includes IMAP. If you plan to use a desktop client, treat IMAP as a requirement and pick a paid plan that includes it.

The 8 best free custom domain email services
#1
Zoho Mail
Best for: Small teams up to five people who want a custom domain free
Visit zoho.com
Starting priceFree; paid plans from 1 dollar per user monthly, billed annually
Free planYes, Forever Free: one domain, up to 5 users, 5 GB each
Zoho Mail is the top pick because it is the only service here that hosts your own domain for free. The Forever Free plan covers one domain and up to five users, with 5 GB of storage each, and no credit card is required. Without IMAP, you live in Zoho webmail and the mobile app, which suits a team that works in a browser but frustrates anyone attached to Outlook or Apple Mail. If you outgrow it, Mail Lite at 1 dollar per user per month billed annually adds IMAP.
What we like- The only genuinely free custom domain plan here
- Paid plans start at 1 dollar per user per month
Watch out for- No IMAP, POP or ActiveSync on the free plan, so desktop mail apps cannot connect
- Free plan is limited to select data centers
#2
Migadu
Best for: One person or small group wanting unlimited addresses across many domains
Visit migadu.com
Starting price19 dollars a year, Micro plan, annual billing only
Free planNo free plan; cheapest is 19 dollars a year
Migadu is a small, independent Swiss email host that charges for the account, not for each mailbox. The Micro plan costs 19 dollars a year and includes unlimited addresses and domains, 5 GB of storage, and full IMAP access, which makes it the cheapest real IMAP mailbox in this guide. The catch is the daily cap: 20 outgoing messages and 200 incoming messages a day, counted across the whole account.
What we like- Unlimited addresses and domains on every plan
- Priced per account
- Full IMAP, SMTP and POP3
Watch out for- Micro caps sending at 20 messages a day and receiving at 200 a day, account wide
- Only 5 GB of storage
#3
MXroute
Best for: Owners of many domains wanting one flat yearly bill
Visit mxroute.com
Starting price59 dollars a year for the Small plan
Free planNo free plan and no trial listed
MXroute sells storage, not seats. The Small plan costs 59 dollars a year for 10 GB of storage, and every plan includes unlimited domains and unlimited email accounts, so adding a second or tenth domain costs nothing extra. Sending is limited to 400 messages per hour per account. The tradeoff is the experience: setup is hands on, with DNS records you add yourself and a control panel that assumes you know what MX, SPF and DKIM records do.
What we like- Unlimited domains and accounts on every plan
- Flat yearly pricing
- Full IMAP, POP3 and SMTP
Watch out for- No free plan or trial
- Setup uses a DirectAdmin style control panel and manual DNS, which suits technical users
Starting price14.88 dollars a year, Launch plan, after a 30 day trial
Free planNo permanent free plan; 30 day trial included
Namecheap Private Email is the cheapest paid mailbox in this guide, and it makes the most sense when your domain already lives at Namecheap. The Launch plan costs 14.88 dollars a year for one mailbox with 5 GB of storage, 10 aliases, webmail, calendar, and full IMAP access. Setup is simple because Namecheap can set the mail records for you. The plan was rebuilt in June 2026 with a cleaner interface, but the rebuild removed the document and spreadsheet tools the old platform carried.
What we like- Cheapest paid start in this guide at 14.88 dollars a year
- Full IMAP, SMTP and POP3
- Calendar and spam filtering included
Watch out for- No permanent free plan, only a 30 day trial
- Launch covers one mailbox with 5 GB and 10 aliases
- Per mailbox pricing grows with the team
#5
Proton Mail
Best for: Privacy focused users wanting encrypted mail on their own domain
Visit proton.me
Starting priceFree; Mail Plus from 3.99 dollars monthly, billed annually (47.88 dollars a year)
Free planYes, but no custom domains on the free plan
Proton Mail is the best known encrypted email service, and its free plan is a genuine way to try it, with 1 GB of storage, one address and 150 messages a day. The important fact for this guide is that the free plan does not support a custom domain. You get an address on proton.me only, and you cannot connect a desktop mail app because IMAP is not included. Mail Plus at 3.99 dollars a month billed annually, or 47.88 dollars a year, adds one custom domain, 10 addresses, 15 GB of storage and IMAP access.
What we like- End to end encryption with a Swiss provider
- Mail Plus adds one custom domain, 10 addresses and 15 GB
Watch out for- Custom domains need Mail Plus
- Free plan is limited to 1 GB, one address and 150 messages a day, with no IMAP
#6
Tuta Mail
Best for: Budget buyers wanting encrypted mail without IMAP
Visit tuta.com
Starting priceFree; Revolutionary from 3 euros monthly, billed annually
Free planYes, but no custom domains on the free plan
Tuta Mail, formerly Tutanota, is a German encrypted email service with a permanent free plan. The free plan gives 1 GB of storage, one calendar and three labels, but it does not support a custom domain and it has no aliases. The Revolutionary plan costs 3 euros a month billed annually and adds 20 GB of storage, 15 extra addresses and three custom domains. The hard limit is protocol access: Tuta has no IMAP, POP or SMTP on any plan, so you cannot use Outlook, Apple Mail or Thunderbird.
What we like- Lowest priced encrypted option with a custom domain
- Revolutionary includes 20 GB, 15 addresses and 3 custom domains
Watch out for- No IMAP, POP or SMTP on any plan
- Free plan is limited to 1 GB with no aliases and no inbox rules
#7
Fastmail
Best for: People wanting polished apps and reliable custom domain mail
Visit fastmail.com
Starting price5 dollars monthly, billed annually (60 dollars a year), Individual plan
Free planNo free plan; 30 day trial included
Fastmail has hosted email since 1999 and it shows in the polish. The Individual plan costs 5 dollars a month billed annually, or 60 dollars a year, and includes 50 GB of storage, calendar, contacts, and unlimited aliases you can send from. Custom domains work on every plan, and you can point several domains at one account. The two real drawbacks are the absence of a free plan and the absence of end to end encryption, which Fastmail omits by design so server side search and rules keep working.
What we like- Custom domains on every plan with unlimited aliases
- Full IMAP, JMAP, CalDAV and CardDAV
- Strong migration tool
Watch out for- No permanent free plan
- No end to end encryption by design
- Costs more than budget hosts
#8Google Workspace
Best for: Teams already using Gmail, Docs, Drive and Meet4.6/5 on
G2 (48,175 reviews, checked Oct 2026)
Visit workspace.google.com
Starting price7 dollars per user monthly, annual plan (84 dollars a year); 8.40 dollars flexible
Free planNo free plan; 14 day trial included
Google Workspace is the default choice for many small businesses, and the reason is familiarity. Business Starter gives you Gmail on your own domain, with 30 GB of pooled storage per user, plus Docs, Sheets, Drive, Calendar and Meet calls for up to 100 people. Setup is quick, deliverability is strong, and almost everyone on your team already knows how Gmail works. The cost is the drawback: 7 dollars per user per month on the annual plan, or 8.40 dollars on the flexible monthly plan, which works out to 84 dollars per user a year.
What we like- Familiar Gmail on your own domain
- Includes Drive, Docs, Sheets, Calendar and Meet
- Strong deliverability
Watch out for- No free plan
- The most expensive entry here at 7 dollars per user per month
- Per user pricing adds up fast
Frequently asked questions
Can I get a custom domain email address for free?
Yes, with one service. Zoho Mail has a Forever Free plan that hosts one custom domain for up to five users, with 5 GB of storage each, at no cost. No other service in this guide offers a free custom domain plan. Proton Mail and Tuta Mail have free plans, but both limit you to their own domain until you pay.
Is the Zoho Mail free plan really free forever?
Zoho calls it the Forever Free plan, and it costs nothing for up to five users on one domain, with no credit card required. It is web only, with no IMAP, POP or ActiveSync, and Zoho says it is available only in select data centers without listing which ones. A sixth user moves everyone to Mail Lite at 1 dollar per user per month billed annually.
Which service is cheapest for one person with one domain?
Zoho Mail is cheapest at zero dollars if you accept web only access. Among paid options, Namecheap Private Email costs 14.88 dollars a year for one mailbox, and Migadu costs 19 dollars a year for unlimited addresses. Fastmail costs 60 dollars a year and Google Workspace costs 84 dollars a year for one user. Add about 10 to 15 dollars a year for the domain name itself.
Can I use Gmail with my own domain for free?
No. A free personal Gmail account cannot send from your own domain. To use Gmail with a custom domain you need Google Workspace, which starts at 7 dollars per user per month on the annual plan, with a 14 day trial. Zoho Mail free is the closest no cost alternative with a Gmail style web interface.
What happens if I outgrow the free plan?
You upgrade to the next tier of the same service, and your address stays the same because you keep the domain. On Zoho Mail, the sixth user moves everyone to Mail Lite at 1 dollar per user per month. On Proton Mail and Tuta Mail, you move to a paid plan to add a custom domain. If you switch providers, you change your DNS records to point at the new host and move your old mail across.
