Enabling the SendGrid Integration

SendGrid is a third-party companion service that allows you to use your own domain for messages sent through Linear.

Enabling the SendGrid Integration

1. Notify Linear’s customer support that you want to enable the service.
2. Create a SendGrid account and choose a plan that fits your agency’s needs.
3. Sign in and authenticate your agency’s domain in SendGrid by following the instructions below.
4. Create an API key in SendGrid by following the instructions found here.
5. Go to Linear’s “Company Settings” section and add the API key to its designated field in the SendGrid settings under the Integrations tab.
6. Enter the no-reply email address into its designated field.
7. Confirm the API key and email address by clicking the “Enable SendGrid” button.
8. Finish the process by clicking the “Confirm” button.

NOTE! Even when using the free plan, we recommend adding your payment information. Otherwise, once you exceed the message limit, emails will no longer be delivered. For example, SendGrid’s free plan includes a limit of 100 emails per day, and during a busy day or at a larger agency, this limit can quickly be reached.

Authenticating Your Domain in SendGrid

This guide explains how to authenticate your domain in SendGrid. You can also follow a visual walkthrough video available here.

1. Go to SendGrid using this link (you will need to sign in).
2. Once you are in the correct view, select “Domain Authentication”.
3. Select your DNS provider in SendGrid.
   • If you are unsure who your DNS provider is, you can check it via a WHOIS service:
     • Go to the WHOIS website.
     • Enter your website’s URL in the search field and click the magnifying glass icon.
     • The WHOIS website will display your DNS provider.
4. Copy and paste the three different CNAME records provided by SendGrid into the correct section of your DNS provider’s control panel.
   • If you are using Cloudflare (you will need to sign in):
     • Go to the dashboard and locate your domain under the “Websites” tab.
     • Select “DNS” → “Records” → “Add new record”.
     • Copy and paste the CNAME records into the correct fields in the control panel.
5. Once the CNAME records have been added, return to SendGrid and check whether the blue “Verified” indicator is visible.
   • Note that domain verification can take up to 48 hours.
