What does the Send Email action do in SendGrid?

Sends a transactional email via SendGrid with from, to, subject, HTML/plain content, and optional CC/BCC/attachments/reply-to. The bread-and-butter SendGrid action.

What inputs does Send Email require?

Required: To Email, From Email, Subject, Content (HTML). Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if SendGrid returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Send Email support batch operations?

Yes. Run Send Email inside a Loop node to process arrays. TinyCommand handles SendGrid's rate limits automatically so you don't have to throttle manually.
