📧 Email Account · Bind Personal / Business Mailboxes

Bind your everyday mailboxes (QQ / 163 / Gmail / Outlook / business mail) to Laifaxin to manage all emails in one place + send from your own mailbox. Once bound, you can do 3 things:

Purpose	Link
1️⃣ Compose Email	Send to a customer individually; see 📚 Compose Email
2️⃣ Mass Email	Large-scale outreach; see 📚 Mass Email
3️⃣ Unified inbox	Centralized multi-account receive; see 📚 Email List

🎯 3 Things to Know Before Binding

Supported mailboxes: the vast majority of personal + business mailboxes (QQ / 163 / Gmail / Outlook / business mail etc.)
Supported protocols: IMAP (receive) + SMTP (send) — ❌ POP3 not supported
Password type: varies by mailbox — login password / app-specific password / authorization code (Gmail / QQ must use authorization codes)

2. Detailed Binding Steps

① Email + Password

Field	Description
Email address	Full email (e.g. `yourname@example.com`)
Password	⚠️ Not the login password! It's the app-specific password / authorization code generated in the mailbox backend (Gmail / QQ / 163 all need this)

Step 1 of binding · Email + password: input fields for email + password; password field note "Some mailboxes require an app-specific password"

⚠️ Gmail / QQ / 163 Must Use App-Specific Password

Don't use the login password — 99% of the time it fails! These mailboxes require third-party apps to use a dedicated password / authorization code:

Mailbox	Password Type	Where to Generate
Gmail	App-specific password	Google Account → Security → 2-Step Verification → App passwords
QQ Mail	Authorization code	Settings → Account → POP3/IMAP/SMTP Service → Generate auth code
163 Mail	Client authorization code	Settings → POP3/SMTP/IMAP → Client authorization password
Business mail (Tencent / Alibaba)	Usually login password	Some require enabling SMTP/IMAP service in the backend first

② Configure IMAP + SMTP Servers

After entering email + password, set up the send/receive servers:

Protocol	Purpose	Key Parameters
📥 IMAP (receive)	Receive emails sent to you	Server address / port / SSL encryption
📤 SMTP (send)	Send your emails	Server address / port / SSL encryption

Common mailbox server parameters (reference):

Mailbox	IMAP Server	IMAP Port	SMTP Server	SMTP Port
Gmail	`imap.gmail.com`	993 (SSL)	`smtp.gmail.com`	465 (SSL) / 587 (TLS)
QQ Mail	`imap.qq.com`	993 (SSL)	`smtp.qq.com`	465 (SSL)
163 Mail	`imap.163.com`	993 (SSL)	`smtp.163.com`	465 (SSL)
Outlook / Hotmail	`outlook.office365.com`	993 (SSL)	`smtp.office365.com`	587 (TLS)
Business mail (Tencent)	`imap.exmail.qq.com`	993 (SSL)	`smtp.exmail.qq.com`	465 (SSL)

For exact values, check the mailbox's official help docs or customer support. Don't guess.

Step 2 of binding · IMAP + SMTP config: left IMAP server / port / SSL + right SMTP same fields, "Verify and Save" button at the bottom

⚠️ Laifaxin Does Not Support POP3

IMAP only (two-way sync, emails stay on server, multi-device consistent). POP3 not supported (one-way download to local, easy to lose emails).

Configure IMAP when binding. POP3 will always fail.

③ Binding Successful

Correct server parameters → a green "Bind successful" toast appears → the mailbox enters the account list, ready to send and receive.

Bind success notification: green toast "Mailbox bound successfully"; the newly bound mailbox appears in the account list

2. Manage Bound Mailboxes

1. View Mailbox List

Go to Settings → Email Account to see all bound mailboxes with sync status / last sync time:

Email Account list: each row shows mailbox status / last sync time / ⚙️ settings button; centralized management of all bound accounts

2. Edit Mailbox Settings

Click the ⚙️ settings icon to the right of a mailbox → enter the edit screen with 4 things you can change:

Setting	When to Change
Email and password	Password changed / want to switch accounts
Account name (nickname)	Give the mailbox a recognizable name (e.g. "Work / Customer Service")
Sync settings	Sync on/off + sync interval (recommended 3 ~ 5 min)
Server config	Update when IMAP / SMTP parameters change

Mailbox edit screen: 4 config sections (email/password / account name / sync settings / server config)

After editing, be sure to click 【Verify and Save】 to apply the new config:

Verify and Save: bottom-right "Verify and Save" button; system retests the connection and applies upon success

💾 Without Clicking 【Verify and Save】 = Nothing Changes

After editing, you must click 【Verify and Save】 — the system reconnects to test parameters; only after success do the changes take effect. Closing the dialog directly → changes lost.

3. Common Error Code Troubleshooting

If you see errors during binding / sync, use this table to locate the issue:

Error / Symptom	Cause	How to Fix
🔴 535 Authentication failed	Wrong password (or didn't use app-specific password)	Use app-specific password for Gmail/QQ/163 and retry
🔴 534 Authentication failed	Mailbox has 2FA but used regular password	Disable 2FA or generate app-specific password in mailbox backend
🔴 Connection refused	Wrong server address / port	Re-fill using the Server Parameter Table
🔴 Connection timeout	Firewall / VPN blocking SMTP ports (465/587)	Disable VPN / let IT open ports / switch networks
🔴 SSL handshake failed	Wrong encryption (SSL vs TLS)	Port 993 uses SSL / port 587 uses TLS
🟡 Login disabled	Mailbox backend IMAP / SMTP service not enabled	Enable third-party client access in mailbox settings
🟡 Too many connections	Sync frequency too high; rate-limited by provider	Increase sync interval to 5 ~ 10 minutes
🟡 DNS resolution failed	Typo in server address (e.g. `imap.gmal.com`)	Copy-paste from official docs, don't type by hand
🟡 Repeated password prompts	Password expired / mailbox revoked access	Regenerate auth code in mailbox backend → in Laifaxin change password + verify & save

💡 Not sure which error it is?

📋 Pitfall Summary

Pitfall	Consequence	How to Avoid
🔴 Gmail / QQ / 163 with login password	99% fail	Must use app-specific password / authorization code (generate in mailbox backend)
🔴 Selected POP3 protocol	Not supported → binding fails	Must use IMAP
🔴 Guessing server / port	Test fails	Use the table above; if not listed, check the mailbox's official help docs
🟡 Sync interval < 3 min	Rate-limited by provider, repeated password prompts	Set to 3 ~ 5 minutes
🟡 IMAP/SMTP not enabled on business mail backend	Protocol disabled, can't bind	Enable IMAP service first in mailbox admin
🟡 Forgot to sync password change	Laifaxin uses old password → all sends fail	Whenever you change the mailbox password, also update Laifaxin immediately
🟡 Didn't click 【Verify and Save】 after editing	Changes don't apply	After editing, always click 【Verify and Save】 to confirm

❓ Frequently Asked Questions (FAQ)

Q1 · What if it says "wrong password" during binding?

Check 4 things in order:

Check	Description
Password type correct?	Gmail / QQ / 163 must use app-specific password / authorization code, not login password
IMAP / SMTP service enabled?	Some mailboxes have them off by default; enable manually in the backend (see mailbox's help)
Server params correct?	Refer to the server parameter table above or the mailbox's official docs
Network issues	Firewall / VPN may block SMTP ports 465 / 587

Q2 · How many mailboxes can I bind?

Laifaxin supports multiple mailbox bindings; the exact number depends on your plan. We recommend binding the 2 ~ 5 you use most (a work mailbox + a customer-service mailbox + a backup); too many becomes a management burden.

Q3 · Do I need to re-sync emails after editing mailbox settings?

Edit Type	Re-sync?
Nickname only	❌ Doesn't affect sync
Password change (verified)	✅ Auto-resumes sync
Server config change	✅ System reconnects / syncs with new config
Sync interval change	✅ Adjusts to new interval (e.g. last 30 days)

Q4 · What's the difference between personal and business mailbox?

Dimension	🏠 Personal	🏢 Business
Identity	Personal (e.g. `tony@gmail.com`)	Company (e.g. `tony@yourcompany.com`)
Professionalism	Average	More professional, ideal for B2B foreign trade outreach
Binding difficulty	Usually app-specific password	Some require enabling IMAP/SMTP first
Mass send risk	Easy to get banned	Same ban risk; safer to use premium channel for mass send

Q5 · Does Laifaxin support POP3?

❌ No. Laifaxin only supports IMAP for receiving + SMTP for sending.

Why: IMAP is the modern email standard (two-way sync, emails on server, multi-device consistent). POP3 is legacy (one-way download to local, easy to lose). All modern mail providers support both IMAP and POP3 — just pick IMAP.

Q6 · Where do customer replies go after binding?

Depends on how you use the mailbox:

Scenario	Where Replies Go
Used in Compose / individual send	Goes to the bound mailbox's own inbox
Mass send with "reply-to = this mailbox"	Goes to the bound mailbox, but easily filtered by anti-spam (not recommended)
Mass send without reply-to set	Goes to the Laifaxin system mailbox (recommended); see 📚 Receive New Emails

💡 Learning Tips

Scenario	Recommendation
🎯 Check mailbox docs before binding	Different mailboxes have different requirements (app password / auth code / server params); check official docs first
🔐 Manage app-specific passwords	App-specific passwords show only once; save immediately after generation, regenerate if lost
📊 Regularly check sync status	Periodically look at the mailbox account list; handle red / abnormal ones promptly (usually password expiry or rate-limit)
🔄 Sync password changes immediately	Whenever you change the login / app password at the mail provider → update Laifaxin immediately to avoid send failures
🏢 Prefer business mailbox	For B2B foreign trade customers, prefer business mailbox for higher professionalism — `xxx@gmail.com` is less impressive
⚖️ Don't abuse mass send after binding	Binding doesn't mean unlimited mass send; your own mailbox still has ban risk on high volume, see Mass Email pitfalls

Topic	Link	Description
📬 Receive New Emails	check-new-emails	After binding, enable sync + notifications for unified receive
💡 Compose Email	compose-new-email	Use bound mailbox to send to individual customers
🚀 Mass Email	email-mass-sending	Pick sending channel for mass send (bound mailbox vs premium channel)
📜 Email List	email-list	Centralized inbox management for all bound mailboxes
✒️ Email Signature	email-signature	Bind different signatures to different mailboxes
📝 Email Templates	email-templates	Reuse templates in mass send / Compose
📊 Email Tracking	email-tracking	See if emails sent from bound mailboxes are opened
