Connecting SendGrid for email

API key generation, sender verification, and what happens on the test send.

SendGrid is one of the two email providers we support; Google Workspace is the other. Use SendGrid when you want a single shared "from" address for the whole team and high-volume drip delivery.

Generate an API key

  1. Sign in to your SendGrid account.
  2. Settings -> API Keys -> Create API Key.
  3. Pick "Full Access" or, more conservatively, "Restricted Access" with Mail Send enabled.
  4. Copy the key immediately. SendGrid only shows it once.

Verify your sender

SendGrid will not send mail from an unverified address. Verify either a single sender or your whole domain:

  • Single sender: Settings -> Sender Authentication -> Verify a Single Sender. Confirm the email SendGrid sends to that address.
  • Domain authentication (recommended): Settings -> Sender Authentication -> Authenticate Your Domain. Add the DNS records SendGrid gives you.

Connect inside LendAxiom

  1. Open the email integration step in the onboarding sidebar, or go to Settings -> Integrations.
  2. Choose SendGrid and open the setup modal.
  3. Paste the API key, sender email, and sender name.
  4. Enter your own email as the test address. We send a single confirmation email to verify the API key and sender are correctly configured.
  5. Click Connect.

If the test email arrives, you are done. If SendGrid returns 401 or 403, the API key is wrong; if it returns 403 with "from address not verified", finish sender authentication first.
