This task can be performed using Inbound
The easiest way to send & receive emails via code.
Implement an email campaign SDK
Connect an email SDK to your application so campaign data, recipient selection, and sending remain in code. Prepare authenticated sending details, a consented audience, message content, and a working unsubscribe process.
Implement the client in a server-side job, load recipients in controlled batches, personalize and validate each message, then submit sends. Record campaign and recipient identifiers to trace failures, prevent duplicates, and separate marketing traffic from transactional email.

- You can send both one-time marketing campaigns and automated transactional emails through the same integration point using simple API calls
- The platform handles email delivery infrastructure automatically so you don't need to manage servers or worry about deliverability rates
- Webhook functionality lets you track email opens, clicks, and replies in real-time to measure campaign performance and trigger follow-up actions
- Clean documentation and code examples help developers get marketing emails running in minutes rather than weeks of custom development work
More about rollout checks
Before a full launch, send to a small internal list and verify rendering, links, unsubscribe behavior, and whether configured webhooks correctly process inbound replies.
- Use idempotent campaign and recipient keys before retrying failed requests.
- Throttle batches and pause the job if failures rise unexpectedly.
- Check consent and suppression status immediately before each send.
