Field Dictionary & Parameters:

Canal Primário: WhatsAppCanal de menor custo e maior engajamento. A mensagem é enviada primeiro pelo chip conectado.

Condição de TransbordoEscolha o gatilho: 'Não Lido em X horas' (ex: 2 horas) ou 'Falha de Entrega' (quando o número não tem WhatsApp ativo).

Canal Secundário: Google RCSSe o WhatsApp não for lido ou o número não possuir WhatsApp, o sistema aciona o Google RCS entregando mensagem rica interativa com selo de empresa verificada.

Canal de Contingência Final: SMS CorporativoPara aparelhos iPhone antigos ou sem conexão com internet, o sistema dispara um SMS curto com link de ação, garantindo 100% de cobertura.

Activate 1% Canary Health Safety Test

👉 Where to Click:Campaign Wizard > 'Anti-Ban Safety' Tab > Toggle 'Canary Batch'

For campaigns exceeding 1,000 recipients, MailerWeb auto-activates Canary Testing: the platform dispatches only to a 1% initial sample and pauses for 15 minutes to measure operator feedback. If error rates remain below 3%, dispatch resumes smoothly for the remaining 99%. If errors spike, the campaign halts to protect chip reputation.

🚨Critical Safety Rules & Ban Protection

🛡️48-Hour Cooldown Window: Dashboard V2 enforces safety intervals preventing the same contact from receiving multiple broadcasts within 48 hours, preventing spam fatigue.
🛡️Business Hours Window: Broadcasts enforce delivery schedules (default: 08:00 to 20:00). Out-of-window runs queue safely until next morning.

❓Frequently Asked Questions & Troubleshooting

No! Waterfall campaigns cancel subsequent stages once read events trigger, saving telecom balance.
