# Integrate SendGrid with AI Email

> [!CAUTION]
> This page is archived and is no longer relevant.

Integrate SendGrid with 6sense AI Email (AIE) to enhance your email outreach capabilities, especially for high-volume campaigns targeting leads not yet ready for meetings. SendGrid excels at handling large volumes of emails efficiently, making it ideal for early-funnel communication.

## Prerequisites

Before integrating SendGrid with AIE, ensure you have:

- An existing SendGrid account with an authenticated domain.
- An API key with full access permissions.

## Connect SendGrid to AIE

To connect SendGrid to AIE, follow these steps:

### 1. Obtain a SendGrid API key

Work with your SendGrid administrator to generate an API key.

**Steps:**

1. Log in to your SendGrid account.
2. Navigate to **Settings** in the left navigation bar.
3. Select **API Keys**.
4. Click **Create API Key**.
5. Enter a name for your API key.
6. Choose **Full Access** to enable sending and reporting functionalities.
7. Click **Create & View**.
8. Copy the generated API key.

### 2. Connect SendGrid in AI Email

1. In AIE, go to **Integrations > SendGrid**.

2. In the SendGrid integration page, go to the Settings tab.
3. Paste the API key you obtained from SendGrid.
4. Click **Connect** to establish the integration.

*Note: If you encounter any errors during this process, refer to the* [*Frequently Asked Questions*](/v1/docs/integrate-ce-with-sendgrid#faq) *section for troubleshooting tips.*

## Create an AI email agent account for SendGrid

After successfully integrating SendGrid, you can create an email inbox using SendGrid.

1. In AIE, go to **AI email agents**.
2. Select **Create email agent**.
3. You should now see a new option – **Connect using SendGrid**.
4. If you have previously set up the SendGrid integration, the API key field will be pre-filled. If not, you can enter the API key here as well.
5. Enter a new email address and name that match the domain authenticated in SendGrid.
  - **Important:** Currently, AIE supports creating new inboxes only. You cannot use an existing email address already set up in SendGrid.
6. Complete the setup to create your new inbox.

*Note: SendGrid requires images to be uploaded at the domain level, not per email address.*

## Use SendGrid in AIE campaigns

With SendGrid connected, you can use it in your AIE campaigns just like any other email provider:

1. Create a new campaign or edit an existing one.
2. Choose your SendGrid inbox as the sender.
3. Compose your email content.
4. Schedule or send your campaign.

## Email deliverability

SendGrid manages email deliverability through domain and IP reputation. Unlike other providers, inbox warm-up in AIE is not required for SendGrid inboxes because SendGrid automatically adjusts rate limits and delivery settings based on account reputation.

- **Inbox Warm-Up:** Not applicable for SendGrid inboxes in AIE.
- **Delivery Optimization:** Handled by SendGrid at the domain and IP level.

For more information on domain and IP warm-up, refer to SendGrid’s official documentation:

- How to Warm Up an IP
- Domain Authentication

## SendGrid account reputation

SendGrid assigns a **Sender Reputation** score ranging from **0% to 100%**, reflecting the health of your sending practices. A higher score indicates better email deliverability.

- **Sender Reputation Score:**
  - **0%–79%:** Low reputation.
  - **80%–89%:** Neutral reputation.
  - **90%–100%:** High reputation.

You can monitor your sender reputation in the AI email agent’s page. All AI email agents connected to a single account share the same reputation.

*Maintaining a high sender reputation is crucial for optimal email deliverability.*

## FAQ

#### What should I do if I receive an error during integration?

- **API Key Error:** Ensure the API key has full access permissions.
- **Authentication Error:** Verify that your SendGrid domain is authenticated.
- **Connection Error:** Check your network connection and try again.

#### Can I use an existing email address from SendGrid in AIE?

No, currently AIE supports creating new inboxes only. You must create a new email address that matches your authenticated domain in SendGrid.

#### Why don’t I see the inbox warm-up tab for my SendGrid inbox?

SendGrid manages warm-up processes automatically at the IP and domain level. Therefore, the inbox warm-up tab is not available for SendGrid inboxes in AIE.
