Email Service Configuration
Some email providers, such as Gmail, require you to configure your mail account to allow sending mail via SMTP before you can use it.
| Parameter | Description |
|---|---|
| Email Service | Select the Email Provider of the address you want to send from. If yours is not listed, you can select Other SMTP Service to do a manual configuration. |
| SMTP Settings | Depending on which Email Service selected above, you need to either enter your login credentials for that service or for the full SMTP connection information in case you selected the “Other SMTP Service” option. |
| Recipient TO Email Addresses | Comma-separated list of email addresses to send the email to. |
| Email Subject | The subject of the email. |
| Email Content | The content of the email. The field supports basic rich text editing. |
Authentication
Authentication
You can use one of the following authentication methods:
- OAuth2 (recommended)
- Basic Auth
OAuth2 is a token-based authentication method. It uses access tokens generated by the service provider to grant authorization for client applications to access user data. Access tokens are unique identifiers that contain user, client application, and permission information. They are short-lived and can be revoked if necessary, providing a higher level of security than Basic Auth. Email providers such as Google and Microsoft may use only OAuth2 for authentication.To create a connection, follow these steps:
- Near the OAuth2 Parameters setting, click +.
- Add a new connection or use an existing one:
- Connection name — create a unique connection name.
- user — add your email address.
- clientId — add a registered client id of the application.
- clientSecret — add a registered client secret of the application.
- accessToken — add an access token. Required only if refreshToken is not available.
- refreshToken — add a refresh token. If it is provided, the Node tries to generate a new access token if existing one expires or fails.
- expiryDate — add an expiration Unix timestamp in milliseconds for the current
accessToken. - accessUrl — add an HTTP endpoint for requesting new access tokens. This value defaults to Gmail
https://accounts.google.com/o/oauth2/token. - tlsOption — specify one of the options if you want to connect with TLS:
- tls — is used by default. TLS is a separate protocol that operates on a different port (usually port 443 for HTTPS).
- starttls — is a command used to upgrade an existing insecure connection to a secure one within the same port.
- none — don’t connect with TLS.
- Click Create.
