Resend and Klaviyo: Bounce Suppression Sync Template
On a schedule, this Spojit template pulls recent hard-bounced emails from Resend and suppresses the matching profiles in Klaviyo so dead addresses stop receiving campaigns.
What It Builds
A Schedule trigger runs the workflow at a set cron interval. A Resend Connector node in Direct mode fetches recent bounce events, a Loop node walks each bounced address, and a Klaviyo Connector node updates each matching profile so hard bounces are suppressed from future sends. The result is a self-cleaning list with no manual exports.
The Prompt
Paste this into Miraxa and it builds the workflow, connecting the tools for you:
Build a workflow that runs every morning at 7am, pulls the email addresses that hard-bounced in Resend over the last 24 hours, and for each one finds the matching profile in Klaviyo and marks it as suppressed so it is excluded from future campaigns.Connectors Used
- Schedule trigger - runs the sync on a 5-field cron interval in your timezone.
- Resend - reads recent bounced email events as the source of truth.
- Klaviyo - suppresses matching profiles so they drop out of sends.
Customize It
Change 7am to your preferred run time, widen last 24 hours to match how often you send, or include soft bounces as well as hard bounces. You can also point the suppression at a specific Klaviyo list instead of the global profile state.
Tips
- Give the Klaviyo connection write scope on profiles so suppression updates succeed.
- Keep the Resend lookback window a little wider than your schedule interval so no bounces slip through a gap.
- Use Direct mode on both connector nodes: the steps are deterministic, so they run with no AI cost.
