Email & Messaging Infrastructure
The infrastructure behind compliant, permission-based communication: email sending servers and IPs, domain setup, list verification and deliverability expertise, plus SMS gateways, WhatsApp Business API access and voice infrastructure. Good inventory is transparent about authentication, sender registration, sending limits and the provider behind the service. Purchased lists, personal account resale and spam tooling are not permitted.

FAQ
Can I buy contact lists or messaging accounts on TrafficNodes?
No. The hub covers infrastructure, software and expertise only. Contact data must come from your own opt-in collection or another lawful basis, and personal or business messaging accounts are never resold.
What should an email infrastructure listing disclose?
Look for authentication details, IP and domain history, sending limits, what is managed by the seller versus you, and the acceptable-use policy. Self-reported reputation figures are shown as unverified in the Node Score.
Is a dedicated IP always better than shared sending?
Not always. A dedicated IP gives you control of your own reputation but needs consistent volume and a warm-up period; low or irregular senders often do better on a well-managed shared pool.
