EmailSMSWhatsAppPushWeb chatVoice

From blank page to delivered campaign.

A clear workflow to build, review, schedule, send, pause, and understand every delivery.

01

Choose the medium

Email, SMS, WhatsApp, and push each get content and delivery controls designed for the channel.

  • Draft, scheduled, sending, stopped, sent, and failed states
  • Audience and segment inclusion or exclusion
  • Test delivery, estimates, fees, and local-time scheduling
02

Shape the message

Compose visually, in blocks, or in source. Personalize content, attach files, preview, and run quality checks before sending.

  • Responsive visual, block, and HTML editing modes
  • AI generation, subject ideas, improvements, and scoring
  • Plain text, tracking modes, link checks, and query parameters
03

Connect with control

Add providers per brand, test credentials, choose senders, synchronize templates, and roll each channel out behind a feature flag.

  • SES, SendGrid, Mailjet, Elastic Email, SMTP, and local stream
  • Twilio and Vonage SMS; Meta, Twilio, and Vonage WhatsApp
  • Web Push, FCM, IMAP, Twilio Voice, and delivery webhooks

Your stack. Your data.
Your delivery.
