How Relay works

Three steps. No group chats. No copy-paste. No per-channel tools.

1

Drop your list

Upload a CSV or paste contacts directly. Relay reads names, phone numbers, and email addresses in one pass.

  • Supported formats: CSV, plain-text paste, JSON array
  • Duplicates are detected and flagged before anything is sent
  • Channel detection: phone numbers with WhatsApp are routed to WA; Telegram handles are routed to TG; emails fall to Email; US/IL numbers without WA fall to SMS
  • Override channel per contact if you know the preference

Example CSV:

name,phone,email
Alice,+19175551234,alice@example.com
Bob,+972501234567,
Carol,,carol@example.com

Brief the agent

Write your message in plain English. The agent adapts tone and greeting per channel — a WhatsApp message reads differently from an email.

  • No templates required — just describe what you want to say
  • The agent re-confirms intent before sending: "You are about to reach 34 people across WA (18), Telegram (9), Email (7). Proceed?"
  • Preview a sample message per channel before approving
  • Optional: add a reply prompt ("Reply YES or NO") and the agent parses answers automatically

Example brief:

"Let everyone on the list know the event is on Saturday the 12th at 7pm. Ask them to confirm attendance. Keep it friendly and under three sentences."

Send and watch the digest

Relay fans out in parallel across all channels. Replies arrive asynchronously and land in a single delivery board, not scattered across four apps.

  • Real-time delivery board: see sent / delivered / replied per contact
  • Reply digest: structured summary of who said what, grouped by answer type
  • Channel personalization: each message is adapted to the norms of that platform
  • Export the digest as CSV or JSON for downstream use

What you do not have to do

  • No group chats where everyone sees everyone else's replies
  • No copy-pasting the same message into four different apps
  • No separate Twilio setup, WhatsApp Business API account, and Telegram bot
  • No manually tracking who responded and who did not
  • No switching context between tools mid-campaign
