Reach your customers instantly through bulk SMS, transactional emails, OTP verification, and automated notification systems that deliver reliably at scale.
Modern businesses need to communicate with customers across multiple channels — order confirmations via SMS, invoices via email, OTPs for verification, promotional campaigns for engagement. Building this messaging infrastructure requires navigating DLT registrations, template approvals, email deliverability, and provider failover.
Gosotek sets up your complete messaging stack using industry-leading providers. We handle the technical complexity of SMS gateway registration, DLT compliance, email domain authentication (SPF, DKIM, DMARC), template management, and delivery optimization. Whether you need to send 100 OTPs per day or 100,000 promotional messages, our infrastructure scales seamlessly and delivers reliably.
Complete SMS infrastructure with DLT registration, sender ID setup, template approval, and provider integration — supporting promotional, transactional, and OTP message types.
Transactional email setup with SendGrid, Mailgun, or AWS SES — domain authentication, SPF/DKIM/DMARC configuration, and deliverability optimization for inbox placement.
Secure OTP system with configurable expiry, retry limits, rate limiting, and multi-channel delivery (SMS + email fallback) for user registration, login, and transaction verification.
Dynamic template system with variable substitution, multi-language support, and A/B testing — manage SMS and email templates from a centralized dashboard without developer involvement.
Real-time delivery status callbacks for every message — sent, delivered, failed, bounced, opened, and clicked. Know exactly what happened to every SMS and email you send.
Comprehensive messaging analytics — delivery rates, open rates, click rates, bounce analysis, and cost tracking across all channels with exportable reports and trend insights.
We assess your messaging volumes, use cases, and compliance needs. Then we handle DLT registration, sender ID applications, domain verification, and template approvals with the relevant authorities.
We integrate SMS and email APIs into your application, configure templates, set up OTP flows, build delivery tracking webhooks, and implement failover between providers for reliability.
End-to-end testing of all message types, delivery verification across carriers and email providers, analytics dashboard setup, and ongoing deliverability monitoring and optimization.
We manage the entire DLT registration process — entity registration, header approval, and template submissions. You focus on your message; we handle the paperwork.
Our email authentication setup and SMS routing optimization ensure maximum deliverability. Messages reach inboxes, not spam folders or blocked lists.
Multi-provider architecture with automatic failover. If your primary SMS or email provider goes down, messages route through backup providers seamlessly.
We help you choose the most cost-effective providers for your volumes and negotiate rates. Intelligent routing reduces costs without sacrificing delivery quality.
