API-first

Every action is an endpoint. Every event, a webhook.

Provision mailboxes, build campaigns straight from enriched data, pull reply events, auto-pause on bounce thresholds. Opens, replies, bounces, mailbox-health changes — pushed live to Slack, your CRM, or your own systems.

The technical operators who pick Smartlead for its API get that here too — except the infrastructure underneath the API is yours.
