Common Enterprise Mailboxes · Setup Quick Reference
Want to bind enterprise email (your company's own domain like yourname@yourcompany.com) to Laifaxin for unified inbox? Check the password type before setting up — use the wrong one and it fails 99% of the time.
- Find your provider → click the Read more link in the table for your provider's row
- Enable service in the admin console → enterprise mailboxes often disable IMAP/SMTP by default; you must enable it in the admin console (may need admin permissions)
- Generate the password and bind → all 7 providers require a separately-generated password from the mailbox backend (auth code / app-specific password / client security password — not the login password) → copy/paste into Laifaxin Email Accounts
For uncovered providers: try the generic IMAP/SMTP setup (see Email Accounts), check the provider's official docs for server addresses, or contact us if all else fails.
1. 7 Enterprise Mailboxes Quick Reference
| Enterprise Mailbox Provider | Type | Setup Guide | Password Type |
|---|---|---|---|
| Google Workspace | Overseas | Read more | App-Specific Password |
| 263 Enterprise Mailbox | Domestic | Read more | Client Auth Code |
| Alibaba Cloud Enterprise Mailbox | Domestic | Read more | Client Security Password |
| NetEase Enterprise Mailbox | Domestic | Read more | Auth Code |
| Tencent Enterprise Mailbox | Domestic | Read more | Auth Password |
| 35 Enterprise Mailbox | Domestic | Read more | Auth Code |
| Zoho Enterprise Mailbox | Overseas | Read more | App-Specific Password |
Enterprise mailboxes use your company's own domain. Mass sending can land your company's domain on spam lists — once domain reputation is damaged, all your colleagues' emails may hit recipients' spam folders, far costlier than a personal mailbox getting flagged.
→ Bulk must use Email Mass Sending · Premium Channels (system channel, doesn't touch your domain, no ban risk, ¥0.007 per email).
Enterprise mailboxes are only for: 1-on-1 follow-up / inquiry replies / formal business correspondence.
2. Password Type in One Sentence
The "Password Type" column above shows Auth Code / App-Specific Password / Client Auth Code / Client Security Password / Auth Password — looks varied, but they're all the same thing:
A standalone password generated by the mailbox backend, specifically for third-party clients (like Laifaxin), not the login password you use to sign in to webmail.
Each provider just calls it something different. When setting up:
- Bind password field gets this standalone password
- Don't enter your webmail login password — none of the 7 enterprise mailboxes allows direct login-password binding
There's one more easy-to-miss step: enterprise mailbox IMAP/SMTP service is often disabled by default — you must enable it in the admin console first (some providers require admin operation).
Common Pitfalls
| Pitfall | Consequence | How to avoid |
|---|---|---|
| IMAP/SMTP service not enabled in admin console | Binding fails directly | Enterprise mailboxes often disable by default; enable in the admin console first (may need admin) |
| Using login password for enterprise mailbox | 99% returns 535 Authentication failed | All 7 enterprise mailboxes require auth code / app-specific password / client security password |
| Can't find password generation entry | Repeated failed attempts with login password | Each provider's setup page (click Read more in the table) has the full path with screenshots |
| Mass sending from enterprise mailbox | Company domain on spam lists, all colleagues affected | Enterprise mailboxes only for 1-on-1 follow-up; bulk must use premium channels |
| Password not saved after generation | Some providers show it only once — gone after closing | Copy and save immediately; if lost, you can only regenerate |
| Forgot to sync after password change | Laifaxin uses old password, all sending fails | After changing the mailbox password, immediately update Laifaxin too |
FAQ
Q1 · How do enterprise mailboxes differ from personal mailboxes?
Enterprise mailboxes use your company's own domain as the suffix (like yourname@yourcompany.com), looking more legitimate and boosting brand reputation. They typically also offer stronger management features, higher security, more storage, and professional tech support.
| Aspect | Personal Mailbox | Enterprise Mailbox |
|---|---|---|
| Suffix | @gmail.com / @qq.com etc. | @yourcompany.com (own domain) |
| Professionalism | Average | High (B2B foreign-trade first choice) |
| Customer impression | Ordinary | Legitimate company |
| Price | Free | Paid (by domain / user count) |
Q2 · Why not sign in with the main password — why auth code / app password?
Auth code / app password protects your main account. Even if a client's password leaks:
- Main login password is still safe; attackers can't sign in to webmail or change account settings
- You can revoke individually for that client without affecting other apps
Q3 · Does enterprise mailbox setup need admin permissions?
Possibly. Enterprise mailbox IMAP/SMTP service is managed by the company's mailbox admin:
- If service is already enabled → you generate the auth code yourself and bind
- If service is not enabled → contact your company's mailbox admin to enable IMAP/SMTP in the admin console
If you're the admin yourself, go to the corresponding provider's admin console to enable it (paths in each setup guide).
Q4 · What if my enterprise mailbox provider isn't in the list?
3 steps:
- Try the generic IMAP/SMTP setup (see Email Accounts)
- Check the provider's official help docs for IMAP/SMTP server addresses + ports
- Still not working → contact us
Q5 · Can I mass-send from enterprise mailboxes?
Not recommended. Mass sending from enterprise mailboxes lands your company's domain on spam lists, affecting all company email deliverability.
| Scenario | Recommended approach |
|---|---|
| 1-on-1 client follow-up | Use enterprise mailbox (Compose New Email) |
| Inquiry replies / formal business | Use enterprise mailbox (company domain most professional) |
| Bulk cold outreach / mass sending | Must use premium channels (doesn't touch your domain, no ban risk) |
| Multi-touch auto follow-up | Use smart sequence + premium channels |
Q6 · Should foreign trade use domestic or overseas enterprise mailboxes?
| Type | Examples | Overseas Deliverability | Suitable for |
|---|---|---|---|
| Overseas | Google Workspace / Zoho | High | European/US-focused, prioritizing international deliverability |
| Domestic | Tencent / NetEase / Alibaba Cloud / 263 / 35 | Medium | Domestic office work primary, foreign trade secondary |
→ Pure foreign-trade teams prefer overseas (Google / Zoho); domestic office + foreign trade use Chinese major brands (Tencent / NetEase). Regardless, bulk sending always uses premium channels.
Learning Tips
| Topic | Advice |
|---|---|
| Step 1 · Pick a provider | Pure foreign-trade prefers overseas (Google / Zoho); domestic office primary use Tencent / NetEase |
| Step 2 · Enable service | Enable IMAP/SMTP in admin console (may need admin) — this step is most often missed |
| Step 3 · Generate password | Most providers require auth code / app-specific password generation, safer than login password |
| Step 4 · Bind | Copy password → go to Email Accounts → fill email + password + IMAP/SMTP servers |
| Step 5 · Enable sync | After binding, enable email sync (recommended 3–5 min) + WeChat / email / browser notifications |
| Use premium channels for bulk | Enterprise mailboxes only for 1-on-1; bulk must use premium channels to protect company domain |

About Enterprise Mailbox Setup
What is an enterprise mailbox?
An enterprise mailbox is an email service using your company's own domain as the suffix (like sales@yourcompany.com). Compared to personal mailboxes (@gmail.com / @qq.com), the biggest trait is the email address IS your company's brand — foreign-trade customers immediately see you're a legitimate company.
Enterprise mailboxes are typically offered by providers (Google / Tencent / NetEase / Alibaba Cloud / 263 / 35 / Zoho etc.). The company pays for it, and an admin allocates accounts to employees.
Why does foreign trade need enterprise mailboxes?
| Aspect | Detail |
|---|---|
| Brand reputation | @yourcompany.com is far more professional than @163.com; overseas customers trust it more |
| Controllable domain reputation | Own domain allows configuring SPF / DKIM / DMARC to boost deliverability |
| Unified management | Admin enables/disables accounts uniformly; employee departures = revoked |
| Larger space + professional support | More capacity than free personal mailboxes, with tech support |
→ For formal business correspondence, overseas customer quotes, contract communications, use enterprise mailboxes.
Domestic vs overseas enterprise mailbox — how to pick?
| Aspect | Overseas (Google / Zoho) | Domestic (Tencent / NetEase / Alibaba Cloud / 263 / 35) |
|---|---|---|
| Overseas deliverability | High | Medium |
| Access from China | Google needs stable network / Zoho stable | Smooth |
| Price | Higher (Google) / Zoho has free tier | Moderate |
| Chinese support | Average | Good |
| Suitable for | Pure foreign-trade, European/US focus | Domestic office primary, foreign trade secondary |
Generic flow for enterprise mailbox setup
No matter which provider, connecting enterprise mailbox to Laifaxin takes these 4 steps:
- Enable IMAP/SMTP service in admin console (often disabled by default — most-missed step)
- Generate auth code / app-specific password / client security password (different names, but none is the login password)
- Copy the IMAP/SMTP server address + port (varies by provider — see the corresponding setup guide)
- Bind in Laifaxin: fill email + password + server settings → test and save
For each provider's specific path, server settings, and screenshots, click Read more in the table above.
How does Laifaxin protect your enterprise mailbox password?
| Aspect | Measure |
|---|---|
| Transit | HTTPS-encrypted end-to-end |
| Storage | AES-256-encrypted database |
| Purpose | Only for syncing / sending/receiving emails, not used for anything else |
Strongly recommend using auth code / app-specific password instead of the login password — even if leaked, it doesn't affect the main account and can be revoked with one click.
