Start with the communication services you need today and expand as your message volume, destinations and channel requirements grow.
SMS pricing can vary based on destination, traffic category, route, message encoding, number of SMS segments, volume commitment, regulatory requirements and applicable taxes. The final commercial rate shown to a customer should come from the active Alert21 plan configured for that account.
Customers buy an Alert21 service, not a provider-specific integration. Alert21 can change eligible upstream routes while the public API remains stable.
Alert21 Email operates on a transparent, usage-based billing model for business-critical transactional alerts. Manage your active email balance, review real-time usage, and monitor billing directly from your Alert21 dashboard. Sign in to view the rate applicable to your account, or contact our team for higher-volume requirements.
Alert21 Website Monitoring provides continuous 24x7 uptime, response time, and SSL certificate tracking. Monitoring subscriptions are separate from communication consumption: Email and In-App notifications are included with all plans, while SMS and WhatsApp alerts consume your account wallets when enabled.
For large-volume or operationally critical workloads, offer a custom plan that can include:
Partners can request commercial structures based on expected volume, number of managed customers, white-label requirements and enabled channels.
No. Destination, message type, encoding, segment count, volume and route can affect the effective price.
Telecom, provider, regulatory, tax and market conditions can change. Alert21 should provide notice where reasonably possible and update the applicable plan/rate card.
Refund eligibility is governed by the published Refund & Cancellation Policy and any signed commercial agreement. Consumed messaging, regulatory, third-party and setup charges are generally not reversible once incurred.
International routes should be presented only for countries where Alert21 has enabled and validated commercial coverage. Contact Sales for current destination availability.
