Email Campaigns via AWS SES
HTML email campaigns with verified sender domains, bounce & complaint tracking via AWS SNS, and one-click unsubscribe headers.
Developer REST API
Integrate message sending into any app with a single API key. Send WhatsApp, emails, and templates programmatically with full variable interpolation.
Meta-Approved Templates
Create, submit, and manage WhatsApp message templates. Real-time status sync — only send approved templates, with full rejection reasons surfaced.
