# Connecting SMTP
To connect SMTP, you first need to retrieve the SMTP credentials from your email service provider.\
In this guide, we’ll show you how to do it using **SendGrid**.
1. Log In to [SendGrid](https://sendgrid.com)
2. Go to [SMTP](https://app.sendgrid.com/guide/integrate/langs/smtp) settings page
Create an API Key
1. Enter a name for the key (for example: *Highlightcards SMTP*).
2. Click **Create Key**.
3. Copy the generated API key — you’ll need it during the Highlightcards setup.
Add SMTP to Highlightcards
> Highlightcards > Left-Hand Menu > [**Account Settings**](https://app.highlightcards.co.uk/settings) > [**Services**](https://app.highlightcards.co.uk/settings/services)
1. In the **Custom SMTP** section, click **Connect Account**.
2. A form will appear asking for:
* SMTP Server
* Port
* Username
* Password
* Sender's email
* Sender's name
3. Copy and paste the SMTP details from SendGrid into the corresponding fields.
4. Click **Connect**.
If everything is correct, the SMTP connection will be added successfully.
Send a Test Email
After connecting, you will see a **Send Test Message** button.
1. Enter your email address.
2. Click **Send Test Message**.
3. Check your inbox to confirm delivery.
If the test email arrives, your SMTP setup is active.
Verify Integration in SendGrid
To ensure SendGrid recognizes Highlightcards’ activity:
1. Go back to your SendGrid dashboard.
2. Open **Activity** or **Integration Verification**.
3. Click **Verify Integration**.
This confirms that Highlightcards can successfully send emails using your SMTP credentials.
