Cascade delivery

Extend the reach of your communication

If a message isn't delivered through the primary channel, Sender automatically retries through the fallback — and keeps going until the customer receives it. A four-channel cascade improves deliverability and reduces lost communication.

Personalization

Make communication more natural and protect against blocks

Personalization and message variation help reduce the repetitiveness of bulk campaigns, make conversations with customers feel more alive and significantly lower the risk of account blocks.

Campaign personalization in Sender
  • Variables

    Insert the customer's name, city, role or the amount of their last order directly into the message. Every message reads as if a manager wrote it personally — response rate and conversion grow, and the team saves hours on manual preparation.

  • Text variation

    Define several wordings of the same phrase — Sender automatically rotates them when sending. Messages don't look like a mass template, slip past messenger anti-spam filters and read naturally, like a regular personal conversation.

  • Scheduled campaigns

    Schedule campaigns in advance and set an exact send time — morning for business messages, afternoon for promotions, weekends for reminders. The customer receives the message exactly when they're ready to read it, and the team isn't stuck watching a timer.

  • Send delays

    Configure pauses between messages — from a few seconds up to minutes. The campaign looks like real work by a manager, WhatsApp and Telegram accounts are protected from blocks, and delivery stays stable even on large lists.
