Single Sends
A Single Send is a one-time nonautomated 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.
The Single Sends API changed on May 6, 2020. Please check the SendGrid Knowledge Center for updates and instructions here: https://sendgrid.com/docs/for-developers/sending-email/single-sends-2020-update/
Create Single Send
POST /v3/marketing/singlesends
Base url: https://api.sendgrid.com
This endpoint allows you to create a new Single Send.
Please note that if you are migrating from the previous version of Single Sends, you no longer need to pass a template ID with your request to this endpoint. Instead, you will pass all template data in the email_config object.
This endpoint will create a draft of the Single Send but will not send it or schedule it to be sent. Any send_at property value set with this endpoint will prepopulate the Single Send's send date. However, the Single Send will remain an unscheduled draft until it's updated with the Schedule Single Send endpoint or SendGrid application UI.
