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/

Schedule Single Send

Schedule Single Send

PUT /marketing/singlesends/{id}/schedule

This endpoint allows you to schedule a Single Send for future delivery using a Single Send ID.

To schedule a Single Send, you must pass a date string in ISO 8601 time format (yyyy-MM-ddTHH:mm:ssZ) using the required send_at field. For example, the ISO 8601 format for 9:00 AM UTC on May 6, 2020 would be 2020-05-06T09:00:00Z. You may also pass the string "now" to send the Single Send immediately.
