# How to connect Sendgrid?

Configure your Sendgrid for warmup

To connect your SendGrid sending account/domain to E-Warmup, you'll use SMTP with an API key. This is the recommended and most secure way.

### Prerequisites

-   A verified sender identity or authenticated domain in your SendGrid account (for best deliverability).
    
-   Access to your SendGrid dashboard.
    

### Step 1: Log in to SendGrid and Create an API Key

1.  Log into your [SendGrid dashboard](https://app.sendgrid.com/).
    
2.  Go to **Settings** → **API Keys** in the left sidebar.
    
3.  Click **Create API Key**.
    
4.  Give it a descriptive name (e.g., "E-Warmup SMTP").
    
5.  Select **Full Access** or at least **Mail Send** permissions.
    
6.  Click **Create & View** and **copy the API key** immediately (it won't be shown again). Store it securely.
    

### Step 2: Note Your SMTP Settings

Use these standard SendGrid SMTP details:

-   **SMTP Host**: [smtp.sendgrid.net](https://smtp.sendgrid.net)
    
-   **SMTP Port**: 587 (recommended with TLS/STARTTLS) or 465 (SSL)
    
-   **SMTP Username**: apikey (exactly this literal string, not your email)
    
-   **SMTP Password**: The full API key you just created (starts with SG.)
    

### Step 3: Connect in E-Warmup

1.  Log into your E-Warmup dashboard.
    
2.  Go to the connection / add inbox section and select **SendGrid** (or **Custom SMTP** if not listed separately).
    
3.  Enter the SMTP details from Step 2.
    
4.  Enter the IMAP details of your mailbox. Please note that, IMAP details will be your mail receiving credentials in IMAP format. It can be your regular mailbox credentials (for example, Google Workspace or Webmail)
    
5.  Connect
    

DONE !!
