With InterFormNG2 you do not need to send out all emails, that you generate. One option is to create emails as .eml files e.g. with the Create PDF document component followed by the To filesystem component to produce .eml files in your file system.
Another solution is to generate the emails with status Held, which means that the email will be generated and prepared to be sent, but it will not be sent before someone has released and sent the email in the email log.
Emails can be generated with status held with these workflow components:
1.Create PDF email. This is the mostly used email workflow component: Create an email with an attached PDF and send it.
2.Send an HTML email. Sends an HTML email without any attachment.
3.To email server. Sends an .eml file via a defined email server.
The held emails can be seen in the email log, where you can open and verify them before you decide to either release and send or delete them.
