# How do I set up my own SMTP so emails reach my users from my own domain?

By default, emails to your downline users are sent through the platform's mail settings. When you add your own **SMTP Connectivity** settings, every email to your users, including login OTPs and signup verification codes, is sent from **your** mail server and your **From** address. This keeps your white-label branding intact and puts delivery in your hands.

## Before you start

- Your white-label domain should already be set up, so your users sign up and log in on your domain.
- Have your SMTP details ready from your mail provider: host, port, encryption, username, password, and a verified sender address.

## Step 1: Open the White Label Manager

Log in to your reseller panel and open **White Label**. The White Label Manager groups every setting into categories: General Settings, Appearance, Pages, Signup / Login, Alerts & Notifications, Sandbox Configs, **Email Configs**, Integrations, Payments and Others. Each card shows **Configured**, **Pending** or **Unavailable**. Use the search box at the top to jump straight to a section.

## Step 2: Open SMTP Connectivity

Under **Email Configs**, open the **SMTP Connectivity** card.

## Step 3: Fill in your mail server details

| Field | What to enter |
| --- | --- |
| **SMTP Host** | Your mail server, for example `mail.yourdomain.com` or `smtp.gmail.com`. |
| **SMTP Encryption** | **SSL** or **STARTTLS**, as your provider requires. |
| **SMTP Port** | The outgoing port, usually 465 for SSL or 587/25 for STARTTLS. |
| **From Name** | The sender name your users see, usually your company name. |
| **SMTP Username** | For AWS SES, the SMTP username (starts with `AKIA…`). For Gmail and most providers, leave it blank to use the From E-Mail as the username. |
| **From E-Mail** | The verified sender address shown to recipients. It must be a real address, not your AWS SMTP username. |
| **SMTP Password** | The password or app password for that mailbox. Use **Show** to check what you typed. |
| **Reply-To E-Mail** | Optional. Where replies should go. Leave blank to use platform settings. |
| **SMTP Auth Mode** | Leave on **Default (automatic)** unless your provider requires LOGIN, PLAIN or CRAM-MD5. |

## Step 4: Set your dispatch limits

Under **Bulk E-Mail Dispatch Settings**, pick the **SMTP Provider Profile** that matches your provider, so bulk emails don't trip its rate limits:

- **Use platform default** — falls back to the platform's settings
- **Google Workspace** — 20 emails/minute
- **Standard** — 120 emails/minute, suits most providers
- **High Volume** — 600 emails/minute, for SendGrid, Mailgun or SES
- **Enterprise** — 1200 emails/minute, for a dedicated server
- **Custom** — set your own Max Batch Size, Rate Limit (emails/sec) and SMTP Reset Threshold

## Step 5: Test and save

Click **Test Connection**. A successful test returns **SMTP Connected**. Fix any error before saving, then save the section. The card now shows **Configured**.

## Step 6: Send a real test

Create a test user under your account, or trigger a password reset on a test account, and confirm the email arrives from your From Name and From E-Mail. Check the spam folder too. If it lands in spam, add the SPF and DKIM records your mail provider gives you to your domain's DNS.
