To send messages through Mailpro’s SMTP relay you need four pieces of information: server host, port, username and password. They are generated automatically when you activate the SMTP service and live in your dashboard. This guide shows exactly where to find them and how to use them safely in your application or third-party tool.
Step 1 — Open the SMTP credentials page
Log into your Mailpro account, click your account name in the top-right corner and choose Account settings. In the left menu select SMTP credentials (or SMTP / API depending on your plan).
Step 2 — Read the four values
| Field | Value | Where to use it |
|---|---|---|
| Server / Host | smtp.mailpro.com | SMTP host setting |
| Port | 587 (recommended), 465 or 2525 | Same field as host, after a colon or in a separate field |
| Username | Your account email address | SMTP username |
| Password | Generated from the SMTP page | SMTP password |
The password is generated and shown once. Copy it immediately to your password manager. You can rotate it whenever you want from the same screen.
Step 3 — Configure your application
Paste these four values into your CRM, e-commerce or notification tool. The setting names vary slightly:
| Tool | SMTP setting path |
|---|---|
| WordPress (WP Mail SMTP) | Settings → WP Mail SMTP → Other SMTP |
| Magento | Stores → Configuration → SMTP |
| Salesforce | Setup → Email → Email Relay Activation |
| Odoo | Settings → Technical → Outgoing Mail Servers |
| Microsoft Exchange | EAC → Mail flow → Send connectors |
Step 4 — Test the connection
Most tools include a "Send test email" button. Use it before going live. If the test fails, the most common causes are: wrong port (use 587), firewall blocking outbound SMTP, or a typo in the username/password.
Authentication mechanisms supported
Mailpro’s SMTP relay accepts LOGIN, PLAIN and CRAM-MD5 over a TLS-encrypted connection. PLAIN over STARTTLS (port 587) is the most widely supported. See SMTP authentication for the full list.
Two-factor authentication and shared accounts
If your Mailpro account has 2FA enabled, the SMTP password is independent of the 2FA token — SMTP clients cannot prompt for a code. Generate a unique SMTP password for each integration so you can rotate one without breaking the others.
Find and rotate your SMTP credentials
Open Account → SMTP credentials in your Mailpro dashboard. For full setup details see the SMTP authentication FAQ and the SMTP server feature.
