Integrates with Twilio SendGrid to validate email addresses using the SendGrid Email Validation API. This allows real-time verification that an email address is valid and deliverable before it is accepted.
Getting a SendGrid Email Validation API Key
The Email Validation API requires a dedicated API key with the Email Address Validation permission. Follow these steps:
- Log in to app.sendgrid.com.
- Go to Settings → API Keys.
- Click Create API Key.
- Give the key a descriptive name (e.g. MyApp Email Validation).
- Select Restricted Access.
- Expand the Email Address Validation category and enable Read Access.
- Click Create & View, then copy the generated key immediately — it will not be shown again.
- Paste the key into the Validation API Key field below.
Important: The Email Address Validation API is only available on Pro plans and above. Ensure your SendGrid account has the appropriate plan before attempting to use this feature.
Fields
- Validation API Key
- SendGrid API key with Email Address Validation read access. Used to verify the deliverability of email addresses. Stored encrypted at rest.
This key is used exclusively for email validation, not for sending email. If you also use SendGrid for email delivery, a separate API key with Mail Send permissions is required for that purpose.
