# Authorize SendGrid

{% hint style="info" %}
Access to **Email Activity** requires an **add-on subscription** in SendGrid. Without this add-on, the Email Activity API is not available. Retention of Email Activity data also depends on the subscription level (typically 7 days by default, extended to 30 days with the add-on).
{% endhint %}

1. Log in to your SendGrid account.<br>
2. Navigate to **Settings** > **API Keys**<br>
