You can read and send your business email from the Gmail app. Add it as an "Other" IMAP account with your full email address and our server settings. For StackCP and Business Email the servers are imap.stackmail.com and smtp.stackmail.com. On cPanel, use your server hostname.
Server settings
The settings depend on the platform your mailbox is on.
StackCP and Business Email
Use these settings for StackCP mailboxes and for Business Email (Google Cloud). They are required when your domain is on Cloudflare.
| Setting | Value |
|---|---|
| Account type | IMAP (recommended) or POP3 |
| Username | Your full email address |
| Password | Your mailbox password |
| Incoming server (IMAP) | imap.stackmail.com — port 993, SSL/TLS |
| Incoming server (POP3) | pop3.stackmail.com — port 995, SSL/TLS |
| Outgoing server (SMTP) | smtp.stackmail.com — port 465, SSL/TLS (or port 587, STARTTLS) |
| Authentication | Normal password (the same username and password for incoming and outgoing mail) |
Username: your full email address (for example [email protected])
Password: your mailbox password
Authentication: Normal password
Incoming (IMAP): imap.stackmail.com port 993 SSL/TLS
Incoming (POP3): pop3.stackmail.com port 995 SSL/TLS
Outgoing (SMTP): smtp.stackmail.com port 465 SSL/TLS (or port 587 STARTTLS)Important: Port 465 always uses SSL/TLS. Never combine port 465 with STARTTLS. If your app only offers STARTTLS, use port 587.
We recommend IMAP. It keeps your email in sync on all your devices.
cPanel
On cPanel hosting, the mail server is your server hostname. This is the same address you use to open cPanel, for example serverXX. followed by the host name. You can see the exact value for each mailbox in cPanel: open Email Accounts, find your mailbox and click Connect Devices.
| Setting | Value |
|---|---|
| Account type | IMAP (recommended) |
| Username | Your full email address |
| Password | Your mailbox password |
| Incoming server (IMAP) | Your server hostname — port 993, SSL/TLS |
| Outgoing server (SMTP) | Your server hostname — port 465, SSL/TLS |
| Authentication | Normal password |
Important: If your domain is behind the Cloudflare proxy, do not use mail.yourdomain.com as the server. Use the server hostname from Connect Devices.
Important — using Cloudflare? Your domain can stay on Cloudflare. In your mail app, connect directly to the mail servers: imap.stackmail.com and smtp.stackmail.com for StackCP and Business Email, or your server hostname for cPanel (see Email Accounts > Connect Devices in cPanel). Do not use mail.yourdomain.com while the domain is behind the Cloudflare proxy. In Cloudflare DNS, set all mail records (the MX target, mail, imap, smtp, pop3, webmail and similar) to DNS only (grey cloud). Email does not work through the proxy (orange cloud).
