[ In short ]
- Zoho Mail is the better pick if price per mailbox matters most: Mail Lite starts at €0.90 per user per month billed annually, and there is a free plan for up to five users.
- Zoho runs EU accounts (zoho.eu) from data centres in Amsterdam and Dublin, and connects to Zoho CRM, Books and the rest of the Zoho suite.
- Skein costs more per person because it is email plus an agent that spots quiet threads, drafts the follow-up in your tone and, by default, asks first.
- Skein is pre-launch: founders can reserve a spot now and try the demo today.
01Zoho Mail or Skein: the short answer
If you want solid business email on your domain for as little as possible, or you already run your company on Zoho CRM and Zoho Books, Zoho Mail is hard to beat. If the problem you want solved is threads going quiet, the quote nobody answered, the investor who never got the data room, Skein adds an agent for that on top of the mailbox.
Zoho Mail is part of Zoho, a large suite of business apps. It offers a free plan for small teams, very cheap paid plans, and Zia, Zoho’s AI assistant, which can write, complete and summarise emails inside the composer.
Skein is business email on your own domain with an agent that follows up on every conversation. Hosted in the EU. The agent notices when a customer, investor or candidate is waiting and drafts the follow-up in your tone. By default nothing is sent without your OK, from the app or, at launch, from Slack or WhatsApp, and every send has a few seconds to undo. For the contacts you choose, you can let it send on its own.

| Skein | Zoho Mail | |
|---|---|---|
| Available | Pre-launch: founders reserve a spot now, teams get access in waves | Available today |
| Price basis | Per person with the agent, plus mailbox-only seats for the rest of the team | Per user per month, billed annually (euro prices, before tax): Mail Lite €0.90 (5 GB) or €1.13 (10 GB), Mail Premium €3.60, Workplace Standard €2.70, Workplace Professional €5.40; free for up to 5 users |
| Hosting region | EU: mail and agent run in Frankfurt | Region by account: zoho.eu accounts are stored in Zoho’s EU data centres (Amsterdam, Dublin) |
| Email on your own domain | Yes, with unlimited aliases and shared inboxes | Yes, on every plan including the free one |
| AI follow-up agent | Yes: spots quiet threads and drafts the follow-up in your tone | Zia writes, completes and summarises email when you ask; no agent that chases quiet threads by itself |
| Approval before sending | Every send by default, with a few seconds to undo; auto-send only for contacts you choose | You send every email yourself |
| Approvals in Slack or WhatsApp | Both, at launch | No; Zoho Cliq is Zoho’s own chat |
| Calendar and meetings | Proposes times and sends the invite from your Google, Microsoft or iCloud calendar | Zoho Calendar included |
| Migration in | Gmail history import; DNS records written for you on supported providers | Migration tools for IMAP, Google Workspace and Exchange |
| Apps | Its own web and phone apps, or Apple Mail, Outlook and the Gmail app | Web, desktop and mobile apps |
| Standards and leaving | IMAP and autoconfig; export every mailbox over IMAP at any time | IMAP, POP and ActiveSync on paid plans; not on the free plan |
Zoho shows prices in your local currency: the ones above are its euro prices, and US prices differ. Mail plans are billed annually; Workplace plans can also be paid monthly, for a little more. The free plan does not include IMAP, POP or ActiveSync, so you read mail in Zoho’s own apps.
03Where Zoho Mail is the better choice
- Price per mailbox. At €0.90 to €3.60 per user per month, Zoho is among the cheapest serious business email. Skein is not trying to compete on that number.
- The Zoho suite. If your CRM, invoicing and help desk are already Zoho, Zoho Mail ties into them in ways a separate email provider cannot.
- A free plan. Up to five users can get email on their domain at no cost, which is fine for a side project or a very early company.
- Archiving and compliance features. Mail Premium adds retention storage, eDiscovery and S/MIME, which some regulated teams need.
- Available today. Skein is not open yet.
04Where Skein is different
The agent does the noticing
Zia helps when you are writing: it generates a draft from a phrase, completes sentences and summarises long emails. Skein looks after the threads you are not looking at. It sees that a buyer has waited three days for an answer, drafts the reply in your tone with the right document, and shows its work: what it read, who is waiting, where each link came from.
By default nothing is sent without your OK, from the app or, at launch, from Slack or WhatsApp, and every send has a few seconds to undo. For the contacts you choose, you can let it send on its own.
One list of who is waiting on whom
Skein keeps one list across the team of who is waiting on whom, with the threads that cost the most if they slip at the top, and sends a daily brief of what came in and what the agent did. It proposes meeting times from your Google, Microsoft or iCloud calendar inside the thread and sends the invite.
EU hosting for everyone, priced per person
Zoho keeps EU data in the EU when your account lives on zoho.eu. Skein runs mail and agent in Frankfurt for every customer. Pricing is per person with the agent, with cheaper mailbox-only seats for teammates who only need an address; details are on the pricing section.
05Who should pick which
- Pick Zoho Mail if you need the lowest cost per mailbox, already use Zoho apps, or need archiving and eDiscovery on a budget.
- Pick Skein if email is where your revenue, fundraising or hiring happens, and the cost of a missed follow-up is bigger than the difference in price per seat.
Many teams use cheap mailboxes for some people and a richer plan for others. Skein works the same way: the people who chase deals get the agent, everyone else gets a mailbox. If you are weighing other options, see Zoho Mail alternatives and European email providers.
06How to switch from Zoho Mail to Skein
A move from Zoho is a standard provider switch: create the new mailboxes, copy the history, then point your MX records at the new host. On supported DNS providers Skein writes the records for you. The importer announced for launch covers Gmail; for history in Zoho, bring it up on the setup call a founder does with each team.
D − 2
Lower the TTL of your MX records
5 min, then wait one old TTL
Set MX (and the records you will change) to 300 seconds. Resolvers keep the old value until the old TTL runs out, often 1 to 24 hours.
D − 2
Verify the domain and add DKIM, SPF, DMARC
15 min, checks in minutes to hours
Add the new provider’s ownership TXT, its DKIM records and its include in your one SPF record. Outgoing mail can work before incoming moves.
D − 1
Create every mailbox and alias
10–60 min
Include shared addresses (hello@, invoices@) and forwarding rules. A catch-all for the first days catches the ones you forgot.
D − 1
Copy existing mail over IMAP
Hours to days per mailbox
Newest first. Gmail allows about 2.5 GB of IMAP download per user per day, so a 10 GB mailbox needs about four days. Start early.
D
Switch MX to the new provider
5 min, propagation up to 300 s
Replace the old MX records; do not leave them at a higher number. Send a test from an outside account.
D + 1 and D + 3
Run a second sync
10–30 min each
Some senders cached the old MX and delivered there. A delta copy picks up what landed late. Keep the old accounts until it finds nothing.
D + 7
Raise the TTL and close the old accounts
5 min
Set the TTL back to 3,600 seconds or more. Cancel the old provider only after the last sync came back empty.
- Check what else depends on Zoho Mail: CRM email sync, Books invoices sent from your address.
- Create the mailboxes and shared addresses in Skein.
- Copy your mail history over IMAP.
- Change your MX records, then update SPF and DKIM and keep DMARC in place.
- Leave the Zoho account active for a few days, then cancel.
Our checklist on email deliverability helps make sure mail from the new provider lands in the inbox from day one.
Skein is not open yet. It opens to its first teams soon, in waves, and founders can reserve a spot now on the founder price. Until then you can try the demo with sample mail, nothing to install.
Questions
- Is Zoho Mail free for business?
- Zoho has a free plan for up to five users with 5 GB per user and email on your own domain. It does not include IMAP, POP or ActiveSync, so you use Zoho’s own apps.
- Where does Zoho store EU data?
- Accounts created on zoho.eu are stored in Zoho’s European data centres, with Amsterdam as the primary and Dublin as the secondary site.
- Does Zoho Mail have AI?
- Yes. Zia, Zoho’s assistant, can generate drafts from a short prompt, complete sentences, summarise emails and suggest auto-replies. It works when you ask; it does not follow up on quiet threads by itself.
- Why is Skein more expensive than Zoho Mail?
- Skein prices the agent, not just the mailbox: each person with the agent gets follow-ups drafted for them. Teammates who only need an address can have a cheaper mailbox-only seat.
