Schedule a Single Send
Sends a Single Send right away when send_at is now, or schedules it for a future ISO 8601 time.
Note: Sends real email to every recipient: confirm the Single Send, its recipients and its content with the user first.
Set up
Use the first option your agent supports.
API (official)
- Base URL: https://api.sendgrid.com

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.
Rules
- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
