Quick answer: Google Workspace and Microsoft 365 are the go-to giants for teams already living in those ecosystems, while Exabytes gives you actual local support that picks up on public holidays. Zoho Mail and Hostinger keep costs lean without looking cheap, IONOS bundles proper Office apps at a fair price, and Amazon WorkMail is the quiet, secure pick if your infrastructure already runs on AWS.
Every Singapore business begins with a domain name and an inbox. Before your first client meeting, before the logo is finalised, your business email sits waiting like an empty desk. The hosting service you pick shapes your daily rhythm of correspondence, file-sharing, and calendar sync. Launching a consultancy during Hari Raya season or opening a shop before Lunar New Year—getting this layer right means one less worry when enquiries start flowing.

Exabytes Business Email
Exabytes has been keeping Singapore businesses’ email afloat from Paya Lebar for over twenty years. Each mailbox starts at 25GB and syncs across your phone, laptop, and tablet without a fuss. You get built-in team chat, video calls, and proper Outlook compatibility—so your calendar and contacts stay in one place. What makes the trip to their website worth it is the spam and virus protection that runs quietly in the background, plus a support team that actually answers on public holidays. It is the kind of setup where you set it, forget it, and get on with your day.
In the Paya Lebar neighbourhood, Exabytes feels like a familiar face for the team that wants a provider with a local address and a two-decade track record.

Google Workspace
Google Workspace runs your business email through the same ecosystem your team probably already uses for Drive, Docs, and Meet. You hang your own domain on it—so no more @gmail.com when emailing clients—and the storage scales from 30GB all the way to 5TB, depending on how deep your pockets are. The real peace of mind comes from AI-powered threat detection that blocks more than 99.9% of spam and phishing attempts before they land in anyone’s inbox. Admin controls let you manage users, devices, and security policies from a single dashboard, and everything stays in sync whether you are on a laptop at home or a phone in a hawker centre.
When your team already lives in Google Drive and Docs, adding business email on your own domain feels like unlocking a professional upgrade without leaving a familiar environment. The AI-powered security works in the background, so you can focus on sending that first proposal rather than worrying about phishing. Ideal for the remote-first startup that needs everything synced from day one.
Phone: +65 6521 8000
Hours: 24/7 support
Price: Plans from about S$8/month per user
Website: workspace.google.com
Suits growing teams who want their email, calendar, video calls, and file storage to feel like one thing instead of five separate logins. If your team already lives in Google Docs and Sheets, this is the natural choice.
Microsoft 365
Microsoft 365 gives you a business email address on your own domain, backed by the full weight of Outlook, Teams, and the Office apps your accountant has been using since the 90s. Each mailbox comes with 50GB or more, and you can send attachments up to 150MB—handy when you are firing off a big deck just before a pitch. Shared calendars, Copilot AI for drafting emails, and tight integration with OneDrive and SharePoint mean your team spends less time hunting for files and more time getting things done. It is the setup for businesses that care about polish, from the signature block to the scheduling assistant.
If your workflows revolve around Outlook, Excel, and Teams, Microsoft 365 makes your business email the hub of a very grown-up productivity suite. The generous attachment limit means you can fire off a full pitch deck without compressing it to a blurry mess—because first impressions count, especially when you’re submitting a tender or a proposal timed for a post-Deepavali deadline.
Address: 1 Marina Boulevard #22-01 One Marina Boulevard, Singapore 018989
Phone: +65 6882 8899
Price: Plans from around S$7.20/month per user
Website: microsoft.com/en-sg/microsoft-365
Fits professional services firms, agencies, and any business where the rhythm of the day is built around Outlook, Excel, and PowerPoint. If your clients already use Microsoft, speaking the same language quietly signals you belong at the table.

Zoho Mail
Zoho Mail runs a tight, ad-free ship out of their office on Cecil Street. You get custom-domain email, storage from 5GB to 50GB, and a control panel that does not feel like you need an IT degree to set up aliases or group policies. Built-in spam protection, e-Discovery for digging up old threads fast, and integration with Zoho’s own CRM suite make it more than just a mailbox. The free plan is genuinely usable—something you do not say often about business email—and even the paid tiers stay kind to a startup budget.
For the entrepreneur who needs the essentials sorted chop chop before launch day, Zoho Mail delivers without fuss. The ad-free interface keeps the focus on correspondence that matters, while the Cecil Street presence adds a layer of assurance. The free plan works beautifully as you test workflows and find your footing, then scales neatly once the business picks up pace.
Address: 105 Cecil Street #10-04 The Octagon, Singapore 069534
Email: [email protected]
Hours: 24/7
Price: Free plan available; paid from S$1.50/month per user
Website: zoho.com/mail
A smart pick for bootstrapped startups, side hustles turning serious, and small teams who want proper business email without a bill that makes the finance guy wince. If you are already using Zoho’s other tools, the ecosystem fit is tight.
Amazon WorkMail
Amazon WorkMail sits on the same AWS infrastructure that powers half the internet, so uptime and security are not really up for debate. Each user gets a 50GB mailbox on your own domain, with encryption keys you control through AWS Key Management. It talks to Outlook, mobile clients, and other mail apps without drama—but where it earns its keep is when your business already runs on AWS services. You are essentially plugging email into an existing stack, with data staying in the region you choose and no advertisements anywhere near your inbox.
Amazon WorkMail slots in like the last piece of a carefully planned infrastructure puzzle for the business already deep in the AWS ecosystem.
Address: 1 Robinson Road #17-00 AIA Tower, Singapore 048542
Hours: 24/7
Price: From US$4/month per user
Website: aws.amazon.com/workmail
Makes sense for tech companies, SaaS businesses, and regulated industries where data sovereignty and encryption are non-negotiable. If your dev team already dreams in AWS, this slots in without a second thought.

IONOS
IONOS gives you ten email accounts with 50GB each, your own domain, and SSL encryption as standard. What sets it apart is the integration with Microsoft Office 365—so you get desktop Office apps alongside your email, without paying two separate bills. They operate multiple data centres including in Singapore, which means local latency stays low and compliance boxes get ticked. Email forwarding, spam protection, and a management panel that does not bury the important stuff under three submenus round out the package.
If you’d rather keep your data in-region and your billing simple, IONOS bundles a Singapore data centre with Microsoft Office 365, so your email and desktop apps arrive in one neat package. For the event planner coordinating vendors for a Hari Raya open house, low latency means time-sensitive confirmations fly without lag—keeping the schedule smooth.
Hours: 24/7
Price: From about S$1.50/month
Website: ionos.com
Hits the sweet spot for small businesses that want the full Office suite bundled with email, at a price that leaves budget for other things. Also worth a look if you need German-style reliability and local data centres.

Hostinger
Hostinger throws in a free domain and SSL certificate when you sign up, which already takes the sting out of getting started. You get 10 to 50GB of storage, unlimited email accounts, and 25MB attachments—enough for most day-to-day business correspondence. Spam filtering and IMAP/POP3 support mean your favourite email app works out of the box, and the control panel is simple enough to hand off to a non-technical team member without a training session. For a business watching cash flow, unlimited accounts at this price point is hard to argue with.
When every dollar counts in your pre-launch phase, Hostinger’s free domain and SSL certificate lift a small but real burden off your checklist. The unlimited email accounts mean you can set up addresses for sales, support, and your whole team without counting costs—ideal for the lean startup that needs to look established before the first customer even walks through the door.
Address: 16 Raffles Quay #33-03 Hong Leong Building, Singapore 048581
Email: [email protected]
Hours: 24/7
Price: From about S$1.50/month
Website: hostinger.com
Suits freelancers, small e-commerce operations, and growing teams who need lots of mailboxes without a per-seat fee that balloons. The free domain and SSL sweeten the deal if you are setting up from scratch.
How to choose
Start with the ecosystem you are already in. If your team spends half the day in Google Docs and Meet, Google Workspace feels like home. If you live in Outlook, Excel, and Teams, Microsoft 365 is the quieter integration. Exabytes is for people who want a local voice on the other end of the line—not a chatbot. Zoho Mail and Hostinger make sense when every dollar counts but you still want a proper custom domain. Amazon WorkMail is niche: brilliant for AWS-native companies, but overkill if you just need to send invoices. IONOS threads the needle for small firms that want Microsoft Office apps bundled with email at one predictable rate.
On price: free plans exist (Zoho’s is genuinely usable), but expect to pay S$1.50–S$8 per user per month for something you can rely on. If someone offers “unlimited everything” for under a dollar, read the fine print on storage and attachment caps. Storage needs vary wildly—a legal firm sending large documents daily will outgrow a 10GB mailbox faster than a café taking reservations. Think about who you call when something breaks, not just the features page.
