Official WhatsApp with approved messages and numbers validated before sending.
View featureDoes Track.co validate emails before sending?
No. WiseData NPS filters invalid, disposable, and previously bounced emails before delivery — you don't waste sends on dead addresses.
What's the infrastructure difference?
WiseData NPS sends email from an authenticated domain — separated between paid and free plans to protect reputation — and uses official WhatsApp (no third-party gateway). This favors deliverability and compliance.
