In this article, you will find out how to enable the SendGrid integration in Synerise which will let you send text messages to your profiles (for example, customers).

## Prerequisites
---
- Create an account in SendGrid.
- In the SendGrid documentation, check the message limits imposed by SendGrid. While planning email campaigns and sending email batches, take these limits into consideration.

## Enabling integration

1. Go to <img src="/api/docs/image/54176ad07f146575310749eba44b7c2f42c1b327/icons/settings-icon.svg" alt="Settings icon" class="icon">**Settings > Apps & Services**.
2. In the list of integrations, find **Sendgrid** and next to the integration name, click **Show**.
    - If there is a connection, you may proceed to [configuring a sender account](/docs/campaign/e-mail/configuring-email-account#configure-a-sender-account)
    - If there is no connection or you want a new one, proceed to the next step.
3. Click **Add connection**.  
    **Result**: A pop-up appears.
4. From the **Security** dropdown list, select one of the following options:  
    - **No security**
    - **SSL**
    - **TSL**
5. In the **Port** field, enter the port number you'll use. If you're not sure which port you use, refer to the [SendGrid documentation](https://docs.sendgrid.com/for-developers/sending-email/integrating-with-the-smtp-api#smtp-ports).
5. In the **Password** field, enter the password to your SendGrid account.
4. Click **Apply**.  
6. Proceed to [configuring a sender account](/docs/campaign/e-mail/configuring-email-account#configure-a-sender-account)

## Tracking bounce events
---
Follow the instructions below to start collecting the following events in Synerise:
- [`newsletter.dropped`](/docs/assets/events/event-reference/email#newsletterdropped),
- [`newsletter.hardbounce`](/docs/assets/events/event-reference/email#newsletterhardbounce), 
- [`newsletter.spambounce`](/docs/assets/events/event-reference/email#newsletterspambounce);

1. In your SendGrid account, perform the [Enable the Signed Event Webhook procedure](https://docs.sendgrid.com/for-developers/tracking-events/getting-started-event-webhook-security-features#enable-the-signed-event-webhook).
2. Provide the key to the Synerise support.
3. In your SendGrid account, proceed to Settings > Mail Settings > Event webhook. 
4. In the **HTTP POST URL** field, enter `https://{SYNERISE_API_BASE_PATH}/webhook-handler/sendgrid.` Depending on the cloud where your workspace is hosted, replace `{SYNERISE_API_BASE_PATH}` with:
    - `https://api.synerise.com` for Microsoft Azure
    - `https://api.geb.synerise.com` for Google Cloud Platform
5. Select **Event notifications**.
6. Select dropped, bounced, and spam reports. These are the only possible options.
7. Save the settings.
