AsiaGB Email Hosting 2026: Unlimited Business Email via DirectAdmin

1. Email Hosting Overview

When you sign up for shared hosting with AsiaGB, professional email hosting is included at no additional charge. This means you can create email addresses using your own domain name — such as [email protected] or [email protected] — without paying for a separate email service or subscribing to a third-party platform.

AsiaGB is a Thai hosting provider with 19 years of experience in the industry, founded in 2007 (BE 2550). Their hosting infrastructure spans server locations in both Thailand and Singapore, giving customers flexibility in terms of latency and regional data preferences. All hosting plans are managed through DirectAdmin, a well-regarded control panel widely used in Southeast Asia.

Email accounts created through DirectAdmin are full-featured: they support standard protocols (POP3, IMAP, SMTP), come with a browser-based webmail client (Roundcube), and include tools for forwarders, autoresponders, and spam filtering. Whether you are a freelancer, a small business, or managing email for an entire organization, the unlimited account limit means you will not run into artificial caps.

2. Why Use a Custom Domain Email

Using a generic free email address such as Gmail or Yahoo for business purposes sends an unintentional signal — it suggests the operation may be informal or temporary. A custom domain email, on the other hand, immediately establishes credibility. When a potential client receives an email from [email protected], the domain itself acts as a trust signal and reinforces brand consistency.

Beyond perception, there are practical advantages. Custom domain emails are portable: if you ever switch hosting providers, you can migrate the address with your domain. They also allow you to set up role-based aliases such as support@, billing@, or noreply@ — addresses that route to real inboxes but are not tied to any single person. This makes team handoffs and internal workflow far simpler.

From an email deliverability perspective, hosting your email on a dedicated server with proper DNS records (SPF, DKIM, and DMARC) significantly improves the likelihood that your messages land in the inbox rather than a spam folder. AsiaGB's email infrastructure supports all three of these DNS-level authentication mechanisms, which is essential for transactional or marketing emails.

3. Creating Email Accounts in DirectAdmin

DirectAdmin is the control panel that AsiaGB uses across all of its shared hosting plans. It provides a clean, no-clutter interface for managing every aspect of your hosting account, including email. Creating a new email account takes under a minute and requires no technical knowledge.

To create an email account, log in to your DirectAdmin control panel using the credentials provided by AsiaGB after signup. From the main dashboard, navigate to the Email Manager section, then click Create Email Account. You will be prompted to enter the username (the part before the @), set a password, and optionally specify a quota limit for that individual mailbox. Click Create and the account is immediately active.

Because AsiaGB enforces no cap on the number of email accounts, you can create one for every team member, department, or purpose you need. You can also manage email at the domain level, meaning if you host multiple domains under one DirectAdmin account, you can create email accounts for each domain independently.

Other email management options within DirectAdmin include:

• Forwarders: Redirect incoming mail from one address to another, including external addresses like Gmail.
• Autoresponders: Set up automatic out-of-office or acknowledgment replies for any email account.
• Catch-All Address: Route all email sent to undefined addresses at your domain to a specific mailbox.
• Mailing Lists: Send a single message to a group of recipients managed through DirectAdmin's list system.
• Quota Management: Set storage limits per individual account if you want to allocate your hosting disk space carefully.

4. Email Features Included

Every email account created under an AsiaGB hosting plan comes with a complete set of features. There is no premium tier required to unlock basic functionality — everything is available from the start.

5. Webmail Access (Roundcube)

Roundcube is a modern, open-source webmail client that AsiaGB provides to all email account holders. It runs entirely in your browser, meaning you can access your email from any device — laptop, desktop, tablet, or phone — without installing any software. Roundcube is available at a URL that follows the pattern webmail.yourdomain.com or yourdomain.com/webmail, depending on your DNS setup.

The Roundcube interface is clean and functional. It supports folder management (Inbox, Sent, Drafts, Trash, custom folders), message search, contact management with an address book, and HTML email composition with formatting tools. On mobile browsers, Roundcube adapts reasonably well to smaller screen widths, though most users prefer to use a dedicated mail app on smartphones for a native experience.

Roundcube's main advantages over proprietary webmail solutions are its reliability and its zero cost — you are not paying a per-seat fee as you would with Microsoft 365 or Google Workspace. For small to medium businesses in Thailand that need functional email access without a recurring per-user subscription, Roundcube via AsiaGB is a genuinely practical option.

Key Roundcube features available through AsiaGB include:

• HTML and plain-text email composition
• Attachment handling with drag-and-drop support
• Folder-based organization and IMAP synchronization
• Integrated contact/address book
• Signature editor (text and HTML)
• Spell-check and identity switching (send from different addresses)
• SSL-encrypted login and session management

6. Anti-Spam & Anti-Virus Protection

Spam and malicious email are persistent problems for any business. AsiaGB addresses this with server-level filtering powered by SpamAssassin, one of the most widely-deployed open-source spam detection systems in the world. SpamAssassin analyzes incoming messages using a scoring system that checks hundreds of rules — including header anomalies, content patterns, DNS-based blocklists, and Bayesian analysis — and assigns each message a spam score.

Messages that exceed a configured threshold are either flagged with a subject-line tag (e.g., [SPAM]) or moved directly to a Junk folder, depending on how your account filters are configured in DirectAdmin. You retain full control over the sensitivity level: if you are receiving too many false positives (legitimate email flagged as spam), you can lower the threshold; if spam is still getting through, you can tighten it.

In addition to content-based spam filtering, AsiaGB's mail server also enforces DNS-based checks:

• SPF (Sender Policy Framework): Verifies that incoming email originates from servers authorized by the sending domain's DNS records.
• DKIM (DomainKeys Identified Mail): Validates the cryptographic signature on incoming messages to ensure they were not tampered with in transit.
• DMARC: Allows domain owners to specify how receiving servers should handle messages that fail SPF or DKIM checks.

For your outgoing mail, you should configure these same DNS records for your own domain to maximize deliverability. DirectAdmin provides a DKIM key generator that creates the necessary TXT record for your domain's DNS zone, which you can add directly through DirectAdmin's DNS management interface.

Virus scanning is also applied to incoming attachments. If a message contains a known malicious file, it is quarantined before it reaches your inbox. This is an important layer of protection, particularly for businesses that receive files from external clients or partners.

7. Configuring Outlook & Gmail

Most users prefer to read and reply to email through a client application rather than webmail. AsiaGB email accounts work with all major email clients using standard POP3 and IMAP protocols.

POP3 vs IMAP — Which Should You Use?

Before configuring any email client, it is important to understand the difference between POP3 and IMAP. The choice affects how your email is stored and synchronized across devices.

For most users in 2026, IMAP is the recommended choice. Since it keeps messages on the server, your inbox stays synchronized whether you check email on your phone, laptop, or webmail. POP3 is only preferable if you specifically need local-only storage or have a very small hosting quota allocation.

Setting Up Microsoft Outlook

Open Outlook and go to File → Add Account. Enter your full email address and click Advanced Options → Let me set up my account manually. Choose IMAP and enter the following server settings:

• Incoming (IMAP): mail.yourdomain.com, port 993, SSL/TLS
• Outgoing (SMTP): mail.yourdomain.com, port 465 or 587, SSL/TLS or STARTTLS
• Username: your full email address (e.g., [email protected])
• Password: the password you set when creating the account in DirectAdmin

Replace yourdomain.com with your actual domain name. Once saved, Outlook will verify the settings and begin syncing your mailbox.

Sending AsiaGB Email Through Gmail (SMTP Relay)

If you want to send and receive from your custom domain address within Gmail's interface — without switching tabs to Roundcube — you can add your AsiaGB email as an external account in Gmail settings. Go to Settings → Accounts → Add another email address and enter your custom email. Gmail will prompt you for the SMTP details: use mail.yourdomain.com on port 587 with STARTTLS, your full email address as the username, and your DirectAdmin email password. For receiving, add your AsiaGB account under Check mail from other accounts using POP3 settings. Note that there may be a polling delay of up to 30 minutes for incoming mail fetched this way; for real-time delivery, using a dedicated email client or Roundcube directly is more reliable.

8. When to Use Dedicated Email Services

AsiaGB's included email hosting covers the needs of most small to medium businesses. However, there are scenarios where you might evaluate a dedicated email service such as Google Workspace or Microsoft 365 instead.

Consider sticking with AsiaGB's included email when:

• You need basic professional email for a team of under 20 people
• Budget is a priority — you want email functionality without an extra subscription
• Your team is comfortable with Roundcube or standard POP3/IMAP clients
• You do not need collaborative calendar, shared drives, or advanced admin tools
• You are a freelancer, startup, or small local business

Consider a dedicated email service when:

• You need enterprise-grade calendar, contacts, and video conferencing tightly integrated with email
• Your team sends high volumes of marketing or transactional email and needs detailed deliverability analytics
• You require advanced admin controls, audit logs, e-discovery, or compliance features (e.g., legal or healthcare sectors)
• You need guaranteed uptime with 24/7 email-specific SLA from a global provider
• You have a large distributed team that relies heavily on real-time collaboration features

The honest answer is that for most Thai small businesses, AsiaGB's bundled email is genuinely sufficient. The cost savings are real — Google Workspace and Microsoft 365 charge per user per month, which adds up quickly. If your main requirement is simply sending and receiving email from a professional address, the included hosting email is the pragmatic choice.

9. Hosting Plans That Include Email

All AsiaGB shared hosting plans include unlimited email accounts, Webmail access, DirectAdmin control panel, SSD storage, free SSL, unlimited bandwidth, unlimited MySQL databases, Softaculous one-click installer, cpGuard malware protection, and twice-monthly backups retained for one year. Email is not an add-on — it is a core part of every plan.

All plans share the same email feature set. The difference between tiers is primarily disk storage. If your team will be receiving and archiving large attachments, the Business plan's 35 GB allocation gives you more headroom before you need to worry about quota management. For lighter usage — primarily text-based emails — even the Starter plan's 5 GB is more than adequate for most businesses.

10. Conclusion

AsiaGB's email hosting stands out primarily because of what it does not charge extra for. Unlimited email accounts, Roundcube webmail, full POP3/IMAP/SMTP protocol support, spam and virus filtering, and DirectAdmin management are all included with every hosting plan, starting at 500 THB per year.

For Thai businesses, freelancers, and organizations that need a professional email address without a per-seat monthly subscription, AsiaGB's bundled email is a genuinely practical solution. The DirectAdmin control panel is straightforward to use even for non-technical users, Roundcube covers browser-based access reliably, and the server-level spam filtering reduces inbox noise without requiring you to configure anything manually.

The key trade-off is that this is shared hosting email — not a dedicated email platform. If your workflow heavily depends on shared calendars, video meetings, or enterprise-grade admin controls, you will eventually outgrow it. But for the majority of use cases in 2026, especially for businesses in Thailand that are just establishing their online presence, AsiaGB's included email is both competent and cost-effective.

With 19 years of operation and server locations in both Thailand and Singapore, AsiaGB brings a track record and regional infrastructure that many newer alternatives simply do not have. If you are already evaluating AsiaGB for web hosting, the email hosting is a strong additional reason to consider them.
