CleverTap supports sending emails through SendGrid.

Integrate SendGrid with CleverTap

  1. In the dashboard, navigate to Settings > Engage > Channels > Email.
  2. Click the + Provider button. The Provider credentials page appears.
  3. Select SendGrid from the provider list.
  4. Provide a nickname for your integration.
  5. Enter the SendGrid API key. For more information on generating the key, see Creating an API key in SendGrid.



    As of December 2020, SendGrid only requires an API key for authentication. Username and password are no longer needed.

    For any clarifications, contact your SendGrid Account Executive or SendGrid Support.

  6. From Address – This value is used as the sender's email address. Most people will not open an email unless they recognize the sender.
  7. Reply Address - This value is used as the reply address. You can receive replies to this address.
  8. Save your settings.
  9. Finally, click Send a test email and fill in your details to test the configuration details you entered. Has it arrived in your inbox? If not, see the troubleshooting steps below.



If you are using SendGrid credentials with SMTP integration, then enter apikey as username and <API_KEY_VALUE> as password.

Bounces, Rejections, Unsubscriptions, and Spam

When an email is classified as bounced, rejected, or when a user unsubscribes, or it is marked as spam, CleverTap needs to be notified so that no further deliveries to that mailbox are attempted. This is considered a good practice and helps improve your sender's reputation. Good sender reputation virtually guarantees better delivery rates.

To enable support for these, follow the steps:

  1. Navigate to Settings > Email Settings and enable Event Notification.

  2. Navigate to Settings from within Event Notification.

  3. In the HTTP Post URL input box, add the Callback URL from the CleverTap dashboard from Settings > Email > Provider > Sendgrid.

  1. Check the following from the Select Options menu in SendGrid Dashboard– Dropped, Bounced, Unsubscribed From, and Marked as Spam.

  2. Save your settings.


Enable Event Notifications for Emails via SendGrid


  • When an email bounces, drops, or unsubscribes, CleverTap will mark the user’s email address as inactive.
  • The count of email bounces is shown on the email report screen.


Check your SPAM folder to see if the message has been classified as SPAM by your email provider.
