A Single Send is a one-time, non-automated email message delivered to a list or segment of your audience. A Single Send may be sent immediately or scheduled for future delivery.
Single Sends can serve many use cases, including promotional offers, engagement campaigns, newsletters, announcements, legal notices, or policy updates.
The Single Sends API allows you to create, retrieve, update, delete, schedule, and deliver your Single Sends. There are also endpoints for searching and statistics to help you maintain and alter your Single Sends as you learn more and further develop your campaigns.
This endpoint allows you to duplicate an existing Single Send using its Single Send ID.
Duplicating a Single Send is useful when you want to create a Single Send but don't want to start from scratch. Once duplicated, you can update or edit the Single Send by making a PATCH request to the /marketing/singlesends/{id} endpoint.
If you leave the name field blank, your duplicate will be assigned the name of the Single Send it was copied from with the text “Copy of ” prepended to it. The name field length is limited to 100 characters, so the end of the new Single Send name, including “Copy of ”, will be trimmed if the name exceeds this limit.
The name of the duplicate Single Send. If you choose to leave the name field blank, your duplicate will be assigned the name of the Single Send it was copied from with the text 'Copy of ' prepended to it. The end of the new Single Send name, including 'Copy of ', will be trimmed if the name exceeds the character limit.
