Send Email

Node catalog Actions

On this page

Queues an email via SMTP. Addresses, subject and body support expressions. Use the visual mail builder or edit HTML/CSS directly.

Usage and specifics

Select an SMTP credential. Build the body visually or with HTML/CSS. Addresses and subject accept expressions; the schema limits attachments to 10.

Technical type : email. Runtime : nodulz.

Credentials and prerequisites

Create and configure the credential : smtp

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the credentials guide for access and rotation.
