SendGrid SMTP Setup

SendGrid lets you configure SMTP to send email through your existing mail client. You need to authenticate with an API key instead of a password, then point your client at smtp.sendgrid.net.


Requirements for SendGrid SMTP Setup

  • Need a SendGrid account with Mail send permission enabled on your API Key.
  • Domain DNS editing access for SPF/DKIM/DMARC configuration.
  • Outbound SMTP ports open: 25, 587, 2525 (STARTTLS) or 465 (SSL).
  • Ability to store your API key securely (env vars, vault, etc.).

SendGrid SMTP Server Settings

  • SMTP Host: smtp.sendgrid.net
  • Ports: 25, 587, 2525 (STARTTLS) or 465 (SSL)
  • Encryption: STARTTLS (587/2525) or SSL (465)
  • Authentication: Required
  • Username: apikey (literal string "apikey")
  • Password: Your SendGrid API key

Generating Your SendGrid API Key

  1. After login to your SendGrid Dashboard, navigate to Settings > API Keys.
  2. Click on Create API Key.
  3. Give it an identical name (e.g., "Orkap Relay Key") and allow Mail send permission.
  4. Copy this generated key - this is your SMTP Password.

Verifying Domain Authentication

  1. Log in to your SendGrid Dashboard, then navigate to Settings > Sender authentication.
  2. Under Domain Authentication, follow the Wizard to add the provided DNS records (SPF and DKIM).
  3. Wait for the DNS update for SendGrid to verify.
