Queue a Triggered Email to send to a recipient after a defined delay; optionally cancel any existing queued emails
The profile data is stored in the queue and is not set to the recipient until the delay period. This means any other changes that made to the recipient's profile data within the delay period will be overwritten for any fields contained in the profile data submitted with this method.
Folder recommended
Rather than trigger a single email, use triggerFolderDelay instead. See Guide to Triggered Emails for more information.
