Text blast (also called bulk SMS, mass text messaging, or SMS broadcast) is the practice of sending a single SMS to a large list of opted-in recipients in one campaign. Despite the rise of email, push notifications, and WhatsApp Business, SMS remains the highest-open-rate digital channel in 2026: 95 to 98 percent of text messages are read within 3 minutes of delivery, versus 15 to 25 percent for email. For time-sensitive promotional offers, transactional confirmations, and emergency notifications, the text blast is still the workhorse channel.
This guide covers what a text blast is, the top use cases by industry, the 5-step setup, compliance requirements by major geography, how to select a provider, pricing, and how Message Central MessageNow runs compliant text-blast campaigns at scale. For specific geographic context, see our Send OTP SMS in India Without DLT guide and the Transactional SMS services page.
Why Choose Text Blast?
Three forces keep SMS text blasts as the highest-ROI channel for many use cases in 2026, despite the proliferation of digital alternatives.
Universal reach. Every active mobile number can receive SMS. There is no app-install requirement, no internet-connectivity requirement, no platform-specific account requirement. WhatsApp covers about 70 percent of mobile users globally; SMS covers nearly 100 percent.
Read rates 4 to 6 times higher than email. Industry benchmarks consistently put SMS open rates at 95 to 98 percent within minutes. Email open rates have declined to 15 to 25 percent and email-fatigue is rising. For time-sensitive content, SMS converts substantially better.
Speed of delivery. A well-routed text blast can reach 100,000 recipients within 5 to 15 minutes. Voice calls, postal mail, even targeted display advertising cannot match that throughput.

How to Send a Text Blast: 5-Step Setup
Step 1: Build a compliant opt-in list
Every recipient must have given prior consent. The consent record should include: phone number, timestamp, IP address, exact consent text shown to the user, and (in the USA) TCPA-compliant written consent for promotional content. For DLT (India) and LGPD (Brazil), capture consent through clear, unbundled opt-in mechanisms (non-pre-checked checkboxes, explicit affirmation in chat or email).
Step 2: Pick the right sender identity per geography
In the USA, register a 10DLC long code or short code through The Campaign Registry. In India, register a DLT entity, header (sender ID), and templates through the operator DLT portals. In Brazil and most of LATAM and Europe, register alphanumeric sender IDs through your provider. The sender identity should match your brand and remain stable across campaigns.
Step 3: Design the message content
Constraints: 160 characters per single segment SMS (155 in some countries due to header bytes), 70 characters if you use any Unicode (emoji, non-Latin characters). Include sender brand at the start, clear value proposition, short call-to-action link (use your own domain, not bit.ly or tinyurl which are filtered), and STOP keyword instructions for promotional content.
Step 4: Schedule and throttle
Define delivery throughput within carrier limits. For US 10DLC at default Trust Score, throughput is 75 messages per second (MPS) on T-Mobile, 25 to 50 MPS on Verizon, 20 to 40 MPS on AT&T. A 100,000-recipient blast takes 25 to 30 minutes at standard 10DLC throughput. Use a number pool to multiply throughput. Schedule outside quiet hours (in the US, TCPA prohibits 9pm to 8am local time of recipient for marketing content).
Step 5: Send, measure, and iterate
Trigger the campaign via dashboard or API. Monitor delivery rate per carrier, click-through on embedded links, opt-out rate, and conversion to downstream action. A healthy promotional blast has 99 percent plus delivery, under 1 percent opt-out, and a click-through of 5 to 25 percent depending on offer relevance.
Top Use Cases by Volume Tier
| Volume tier | Typical sender format | Best for |
|---|---|---|
| Under 10,000 per blast | 10DLC (US) / DLT long code (India) / Alphanumeric (EU) | Small business, local promotions |
| 10,000 to 100,000 per blast | Number pool of 10DLC or DLT long codes | Mid-market e-commerce, fintech |
| 100,000 to 1M per blast | Short code or DLT pool | Large e-commerce, banks, govt |
| 1M to 100M+ per blast | Dedicated short codes + multi-route | Telco, govt emergency, mega-brands |
Compliance Requirements by Geography
USA: TCPA + 10DLC
The Telephone Consumer Protection Act requires prior express written consent for promotional SMS. Statutory damages can reach $1500 per non-compliant message. Use registered 10DLC long codes or short codes through The Campaign Registry. Honor STOP, UNSUBSCRIBE, QUIT, and END keywords immediately. Restrict promotional sends to 8am to 9pm recipient local time.
India: DLT registration mandatory
The Telecom Regulatory Authority of India (TRAI) requires every business sending commercial SMS to register their entity, sender headers, and templates on operator-managed DLT registries. Promotional SMS additionally requires opt-in records on the National Do Not Call (NDNC) registry. Unregistered local-route SMS is filtered or blocked.
Brazil: LGPD + ANATEL
The Brazilian General Data Protection Law (LGPD) requires explicit consent for marketing SMS, with timestamp, IP, and consent text logged. ANATEL imposes anti-spam controls. Opt-out via STOP keyword is mandatory. Penalties under LGPD reach 2 percent of Brazilian revenue, capped at R$50 million per infraction.
UAE: TDRA telecom rules
The UAE Telecommunications and Digital Government Regulatory Authority requires sender ID registration and opt-in for promotional content. Strict enforcement against unsolicited SMS.
EU: GDPR + ePrivacy Directive
Explicit consent required for marketing SMS to EU residents. Right to be forgotten obligations apply to recipient phone-number records. Penalties up to 4 percent of global revenue.
How to Select a Text Blast Provider
Eight criteria separate good text blast providers from inadequate ones.
- Direct operator connectivity. Providers with direct carrier routes (vs aggregator-of-aggregators) deliver at 99 percent plus. Indirect routes drop to 80 to 92 percent.
- Throughput at scale. Can the provider deliver your peak blast volume within your acceptable window? Verify MPS limits per carrier.
- Compliance tooling. TCPA consent capture, DLT registration support, opt-out automation, time-of-day enforcement.
- Per-carrier analytics. Delivery rate per carrier helps catch routing problems early.
- Geographic coverage. If you serve users in multiple countries, the provider must support each market with native compliance.
- Pricing transparency. Pay-as-you-go pricing with carrier surcharges bundled into the headline rate. Avoid surprise invoices.
- API quality and integrations. Clean REST API, pre-built integrations with e-commerce platforms (Shopify, Magento), CRMs (Salesforce, HubSpot), and marketing automation (Mailchimp, Klaviyo).
- Support availability in your time zone. When a blast underperforms at 11pm local time, you need someone responding in minutes.

Common Text Blast Mistakes
- Sending without proper opt-in. The single biggest source of TCPA, LGPD, and DLT penalties. Document consent for every number on every list.
- Mixing promotional and transactional content. Adding any promotional content to a transactional template can break the regulatory exemption and trigger filtering or fines.
- Using URL shorteners like bit.ly or tinyurl. Carrier filters block these aggressively. Use your own short-link domain.
- Sending outside quiet hours. US TCPA prohibits 9pm to 8am recipient local time for marketing. Always enforce time-zone aware scheduling.
- Forgetting to include sender identification. Even on registered routes, the message body should start with your brand name so users recognize the source.
- Not maintaining a suppression list. Users who STOP must be permanently suppressed. Re-sending to an opted-out user is the cleanest path to TCPA litigation.
