The Send Email API enables you to send emails using your verified sending domain to one or multiple recipients in a single API call. You can control key elements like recipients (to, cc, bcc), subject, and content through the personalizations object, while the settings object allows advanced configurations such as scheduling, tracking, and global bcc.
Optional features include tagging emails for performance analysis (tags), setting delivery priority via priorityflag, and compressing the payload with gzip to optimize data usage. Personalization lets you tailor shared content uniquely per recipient group, enhancing engagement from a single API request.
To view sample request payloads for these use cases, open the Examples panel on the right.
