Google Workspace alternative for multiple domains when you only need email

I run 4 products, each on its own domain, and for a while I answered support for all of them from my personal Gmail. If you're searching for a Google Workspace alternative for multiple domains, the useful answer depends on the job: plain email, the cheapest real mailboxes, forwarding into Gmail, or one inbox plus a send API for your apps.

Workspace aliases look free until you want a real inbox per domain. And Gmail's Send-As for outside addresses, the trick I used to reply as each domain, ends in January 2027.

I build Mailyond, so I'm not neutral. Mailyond lets you send and answer email across all your domains, with every address in one inbox. Prices below are from each vendor's pricing page, checked October 6, 2026.

Google Workspace alternative for multiple domains: what you are actually replacing

I didn't want to replace Docs or Meet. I wanted email on several domains to stop being annoying. Full-suite Workspace replacement lists answer a different question.

The alias trap is what pushes people off. Google bills users and lets you add domains for free (Google Workspace pricing). Add brand-b.com as an alias domain and you@brand-b.com lands in your main mailbox at no cost, but you pick the right From address on every reply.

If you want support@brand-b.com as its own inbox, that's another user, and Business Starter is $7 a month per user on the annual plan or $8.40 on Flexible. 5 domains with their own inbox is $35 a month. The full seat math is in Google Workspace multiple domains pricing.

The free route is forwarding into personal Gmail plus Send-As, which I ran for a while. One of my products has an in-app feedback form that emails my support address with the customer as reply-to. I hit reply, and the answer went out from my personal Gmail instead of support@, 10+ times before I noticed. Send-As is a per-address setup, so it's the step that gets half-finished when a new domain shows up.

The four jobs, and which tool fits each

Each tool here is good at one or two of these. Pick the job first.

Job 1: plain email on several domains

Fastmail is what I'd pick. Individual is $5 a month billed yearly ($6 month to month), with your own domains and many custom addresses on one account. The pricing page lists no transactional send API, so password resets from your app still need a second service.

Job 2: the cheapest real mailboxes

Zoho Mail Lite is $1 per user per month billed annually (5 GB), with no monthly plan. The interface feels old to me, and app email is a separate product, ZeptoMail. More per-mailbox options are in email hosting for multiple domains.

Job 3: forward everything into Gmail

ImprovMX forwards and adds SMTP sending: Light is $50 a year for 5 domains, Premium $9 a month for 30. There's no inbox.

Forward Email's free plan only forwards. Its $3 a month plan is more than a forwarder though: unlimited domains, mailboxes with 10 GB pooled storage in any IMAP client, outbound SMTP and a developer API. An older version of this post called it forwarding only, which was wrong.

Cloudflare Email Routing is inbound only. Sending is a separate beta on the Workers Paid plan, through code, with no inbox.

The catch is the reply. Starting January 2027, Gmail removes Send as for non-Google addresses on web and mobile (Google's announcement). Forwarding keeps working, and Workspace's own Send as isn't affected. If outbound is your problem, send email from multiple domains goes through the routes.

Job 4: one inbox plus a send API

This was my job. Support mail arrives on several domains, I reply as the address it came to, and my apps send from the same domains. Usually that's three tools: a send API, a forwarder for receiving, Gmail for replying. Resend now has Inboxes (3 per plan, open to everyone as of October 2026), which is fine for a couple of addresses. Mailyond is built for my case: several domains in one inbox, at a flat price.

Alternatives compared

Zoho wins on price per mailbox and loses on the interface. Forward Email at $3 is the best value here if you don't need every domain in one inbox.

When to stay on Google Workspace

Stay if it's your primary work inbox, you use Docs, Drive or Meet every day, or you run one company on one domain with an alias or two. Then the seat pays for more than email.

I'd move the extra domains if they're side projects that get a few emails a week, you pay a $7 seat for a mailbox you barely open, or your apps need a transactional send API like Resend's, which Workspace isn't built for.

Where Mailyond fits

Mailyond prices a bundle of domains instead of seats. Basic is $10 a month for up to 5 domains and 5,000 emails a month (sent plus received), 1 member, then $1.80 per 1,000. Pro is $20 for up to 10 domains, 10,000 emails and 3 members, then $1.50 per 1,000. Agency is $40 for up to 30 domains, 25,000 emails and 10 members, then $1.30 per 1,000.

Every domain lands in one inbox, and you answer from the address people wrote to. One inbox for multiple domains shows how that works day to day.

Subdomain mode means your main email stays put: point support.yourdomain.com at Mailyond and you@yourdomain.com stays on Gmail or Workspace. For your apps there's a REST send API that's Resend-compatible, so the Resend SDK keeps working with a Mailyond key. Setup is a few DNS records per domain, verified in the app.

It's email only, and Zoho and Forward Email are cheaper per mailbox. What I'm selling is the inbox and the send API on the same domains. Pricing fits on one screen, and you can get started for free with a 7-day trial.

FAQ

What is the best Workspace alternative if I own several domains?

The one that fits your job: Fastmail for plain email, Zoho for cheap mailboxes, Forward Email for your own mail client, Mailyond for one inbox plus a send API.

Does Google Workspace charge per domain?

No, it charges per user. Alias domains are free, but a separate inbox on another domain is another paid user.

Is Fastmail better than Google Workspace for several domains?

For plain email, I think yes. $5 a month covers your own domains on one account. Neither is built for transactional app email or has a send API like Resend's.

Is Zoho Mail a good Workspace alternative for email only?

If price matters most, yes, at $1 per user per month annually. Expect a dated interface and a separate product for app email.

Can Cloudflare Email Routing replace Google Workspace for multiple domains?

Only for receiving. It has no inbox, and sending is a separate beta on Workers Paid.

When should I stay on Google Workspace instead of switching?

When you use Docs, Drive or Meet daily, or run one company on one domain.

Can I keep Gmail for my main domain and only move project domains?

Yes. Each domain has its own MX records, so your main domain can stay on Google. Mailyond's subdomain mode moves only support.yourdomain.com.

The short version

Pick by job. If your extra domains get a few emails a week and your apps send from them too, that's the setup I built Mailyond for.
