Bulk SMS & gateway overview
What Is Bulk SMS & How Does It Work?
Bulk SMS is the way of sending out promotional or transactional messages with higher quantities simultaneously. Every organization needs to spread various messages to their clients, and this service makes mass communication easier and more dynamic. The following method is a very practical way of reaching out to a group of people on any occasion, from urgent notifications to special offers.
For example, schools use messaging to send urgent notifications to students, and those messages reach their target reliably. SMS is also a practical channel for public agencies to share information quickly.
Text messaging can be a necessity at any point in an organization's work. It is essential to choose a reliable bulk SMS provider for your use case.

How Bulk SMS Works
With Send99, most teams use the same three-step flow whether they use the web portal, HTTP API, or SMPP. Step one: upload or sync your contacts. Import a CSV, connect your customer database, or add numbers in international format from your application so you always send to a clean, de-duplicated list. Step two: compose the message and personalize it. Write the body in the web UI or generate it in code, then insert fields such as first name, order ID, or appointment time so each recipient gets a message that feels 1:1, not a generic blast. Step three: send or schedule, then read delivery results. Launch the campaign in real time, or set the exact date and time in each time zone. After send, you get delivery reports that show which messages were delivered, failed, or are still pending, so you can change routing, fix invalid numbers, or retry critical OTP and alert flows. Scheduling helps you match local business hours, while personalization improves conversion on marketing, cart recovery, and service notices.
1. Upload contacts
Import CSV files, use API endpoints to register subscribers, and validate or segment lists before a send. Deduplication and HLR options reduce wasted traffic on inactive numbers and keep your costs predictable while protecting sender reputation on major MNOs.
2. Compose the message
Build templates in the platform or in your own stack for one-time password, order updates, and promotional bursts. Add merge fields for personalization, preview rendered output per country, and store approved templates for compliance teams to audit before you scale volume.
3. Send & report
Fire campaigns instantly or use calendar scheduling. Track delivery, failures, and latency in near real time, export logs for finance and support, and wire webhooks to your own BI tools so you always know that critical alerts and time-sensitive codes reached the handset.
Industries We Serve
We power messaging for teams that need reliability, clear pricing, and direct carrier access—not gray routes. Below are a few of the verticals that rely on Send99 every day for high-volume, mission-critical traffic.
E-commerce & retail
Send order and shipping confirmations, low-stock and back-in-stock SMS, and abandoned-cart reminders. Fast delivery keeps customers informed from checkout to doorstep, while timely nudges recover revenue without another email in the spam folder.
Healthcare
Remind patients of appointments, lab availability, and prescription windows. SMS reaches people faster than post for time-sensitive information, and short messages fit clinical workflows that already have strict privacy and process requirements.
Financial services
Use SMS for one-time passcodes, balance and fraud alerts, and payment-due notifications. When seconds matter, a text to a verified phone number is the channel customers already trust for their bank and wallet apps.
Education
Notify students and parents about closures, exam schedules, and registration deadlines. SMS cuts through app fatigue for youth programs, universities, and training providers that must reach a broad demographic quickly.
Logistics
Push delivery window updates, driver dispatch notices, and proof-of-delivery follow-ups. Field teams and customers stay aligned when every stage of the journey triggers an automatic, read-in-seconds text instead of a missed call.
SaaS & technology
Enable two-factor authentication, passwordless login, and password reset via SMS, plus product onboarding and trial nudges. Our REST and SMPP options drop into the stack you already run in production, with JSON where your engineers expect it.
Why Choose Send99?
190+ countries
We emphasize direct carrier routes instead of opaque gray routes, so you get traceable, stable delivery to local MNOs and clearer support when a country or MNO changes policy overnight.
99.9% uptime SLA
The platform is built for enterprise-grade traffic: redundant systems, capacity for burst sends, and monitoring so API and SMPP clients stay up when your product launch or campaign spikes hard.
Developer-friendly API
A modern REST API with JSON for send, balance, and delivery callbacks—plus SMPP for operators and power users. Most teams can complete a five-minute integration with our docs and code samples, then go live in staging the same day.
Human support
You can reach a real person on WhatsApp, Telegram, and email when a route acts up, a 10DLC or sender-ID rule changes, or you need a last-minute send profile—no ticket black holes.
Global SMS Coverage
Send99 routes traffic to hundreds of direct and hosted connections worldwide. The map below is a high-level view of the regions and examples of operator coverage; your account manager can share MCC/MNC and pricing for any destination you plan to use in production.
North America
USA—national coverage on major MNOs including AT&T, Verizon, T-Mobile, and U.S. Cellular (Sprint-legacy routes where applicable to T-Mobile’s network), plus long-code and 10DLC / toll-free use cases. Canada—Bell, Rogers, Telus, and national MVNOs for alerts and two-way use cases with compliant origination.
Europe & UK
United Kingdom—EE, O2, Vodafone, and Three with reliable handset delivery for A2P and transactional flows. EU—broad on-net and hosted routes in France, Germany, Italy, Spain, the Nordics, and CEE, with localization for alphanumeric sender and numeric options where each regulator allows.
Asia-Pacific & Middle East
Australia—Telstra, Optus, and Vodafone Australia for national campaigns and OTP. APAC & Middle East—coverage in Singapore, Japan, India, GCC states, and more; ideal for global SaaS, travel, and logistics that need a single API with many destinations.
Latin America & Africa
We connect to national carriers in Brazil, Mexico, Argentina, and key markets in Latin America, and to tier-1 and tier-2 operators across Africa for banking, NGO, and digital-commerce programs that need SMS as the default mobile channel where data coverage is still uneven.
How we test routes
You can start with a small test credit pack, run live and sandbox sends, and review DLRs before you book large campaigns. We recommend validating sender IDs, content templates, and local quiet-hour rules in each country before you go live, because final delivery always depends on local operator and regulatory acceptance.
Frequently asked questions
What is Send99?
Send99 is a global application-to-person (A2P) SMS gateway for businesses. It combines a web platform, an HTTP SMS API, SMPP connectivity, and two-way messaging so teams can send OTPs, alerts, notifications, and marketing campaigns to more than 190 countries from one account.
How much does Send99 cost?
Pricing is pay-as-you-go and starts from €0.022 per SMS on standard US business routes. The rate for any other destination depends on the network, route class, volume, and sender type, so the live rate card in your account is the source of truth. There is no setup fee, and volume discounts apply as usage grows. See bulk SMS pricing for details.
Which countries can I send SMS to?
Send99 routes traffic to more than 190 countries. Dedicated coverage pages explain local sender IDs, regulations, and use cases for the USA, the UK, Canada, Australia, and seven European and Middle Eastern markets. Ask our team for MCC/MNC-level routing and pricing for any destination you plan to use in production.
Does Send99 offer an API and SMPP?
Yes. The HTTP API supports GET and POST requests for balance, sending, delivery reports, and inbound messages, with JSON responses. High-volume teams can use SMPP binds instead. Both are documented in the API documentation, and our team can help with test credits, sender registration, and production cutover.
Is there a free trial?
Yes. You can create an account and receive test credits to verify delivery to your own handsets, check delivery reports, and validate latency before funding a production balance. The trial is intended for good-faith testing and staging, not for unregistered high-volume marketing.
How do I keep SMS campaigns compliant?
Collect documented opt-in consent, identify your brand in every message, honour STOP and HELP requests, and follow the rules for each destination. Registration such as 10DLC in the USA or sender-ID approval in the UAE may be required before traffic goes live. Our country pages summarise the local rules, but the sending business remains responsible for consent and content.
What support is available?
You can reach our team by email at [email protected], on WhatsApp at +44 7418 311837, or on Telegram. Support hours are 9:30 AM to 5:30 PM, and we help with integration, sender registration, route troubleshooting, and account questions. See the contact page for all channels.
