Global Bulk SMS Service & Text Messaging for Business

Bulk SMS features for growing teams

A bulk SMS service should do more than accept a list of numbers. Send99 combines campaign scheduling, personalised templates, delivery reporting, and API access so marketing, product, and operations teams can work from the same platform. You can upload contacts in the portal, trigger messages from your own application, or connect an existing CRM through webhooks.

Campaign control

Schedule sends for a specific time zone, split large lists into batches, and use merge fields for names, order references, or appointment dates. Every submission returns a message ID that can be reconciled with a delivery report, so support teams can answer "did it arrive?" with evidence rather than guesswork.

One platform, several integration paths

Use the web portal for ad-hoc campaigns, the HTTP SMS API for application-triggered messages, or SMPP for high-throughput enterprise traffic. The same account can mix channels, which makes it practical to start with the portal and move a growing use case to an API later without changing providers.

Delivery, routing, and sender IDs

Delivery quality depends on the route, the sender ID, and the destination network. Send99 routes through a mix of direct and hosted connections and returns delivery reports so you can see which messages were accepted by the carrier. Actual handset delivery can still be affected by the subscriber being offline, carrier filtering, or a number being inactive — which is why list hygiene and correct sender registration matter as much as gateway choice.

Sender rules vary by country. The USA generally requires 10DLC, toll-free, or short-code registration for A2P traffic. Many European markets accept alphanumeric sender IDs, while the UAE requires pre-registration and content approval. Our country coverage pages explain the local options, and our team can confirm what is available for your destination and volume.

Consent, opt-out, and compliance

Compliant bulk messaging starts with a clear opt-in that records who consented, when, and through which channel. Every promotional message should identify the sender, explain how to opt out, and honour STOP or equivalent requests promptly. Transactional messages such as OTPs and delivery alerts should be kept separate from marketing so carrier filtering or quiet-hour rules do not delay time-sensitive traffic.

Rules differ by market: TCPA and 10DLC in the USA, CASL in Canada, PECR and UK GDPR in the UK, GDPR and local ePrivacy rules across the EU, the Spam Act in Australia, and TDRA requirements in the UAE. Send99 provides the gateway and reporting; the sending business remains responsible for its consent records, content, and registration obligations. See our terms for the acceptable-use framework.

Integration options and getting started

Most teams start with a test account: verify credentials, send to a handful of handsets, inspect the JSON response, and confirm that delivery reports match expectations. From there, production usually requires a balance top-up and any destination-specific sender registration. The API documentation covers balance, send, report, and inbound-message endpoints, while the pricing page explains how per-message rates and volume tiers work.

If you need help choosing between the portal, HTTP API, and SMPP, send us your monthly volume, destination countries, and whether you need two-way replies. We will recommend the simplest setup that meets your throughput and compliance requirements, and provide a written quote for your finance team.
