Frequently Asked Questions

Bulk SMS marketing is the practice of sending large volumes of text messages simultaneously to a list of opted-in mobile subscribers. It achieves average open rates of 98% and is typically read within 3 minutes of delivery - making it the highest-ROI direct marketing channel available globally. BulkSMSHub delivers bulk SMS to 190+ countries with direct carrier connections.

BulkSMSHub plans start at $29/month for 5,000 SMS credits. Per-message pricing varies by country: India ($0.004), USA ($0.008), UAE ($0.022), UK ($0.032), Australia ($0.038), Germany ($0.048). Volume discounts of 15-40% apply for monthly volumes above 100K. Use our free SMS Pricing Calculator for an accurate estimate.

A2P (Application-to-Person) SMS is automated messages sent from a business application to end-user phones - OTPs, appointment reminders, order confirmations and marketing promotions via dedicated carrier infrastructure. P2P (Person-to-Person) is personal messaging between individuals. A2P uses dedicated high-throughput routes built for automated, high-volume delivery with compliance controls.

Yes. BulkSMSHub is an official Meta Business Solution Partner providing full WhatsApp Business API access including green tick verification, broadcast messaging to unlimited contacts, interactive buttons, rich media messages and AI chatbot integration. WABA onboarding takes 3-7 business days.

Bulk SMS reaches every mobile user globally (5.3B devices) including feature phones with no internet required, achieving 98% open rates. WhatsApp reaches 2+ billion users with rich media, buttons and catalogues but requires internet access. SMS is broader reach; WhatsApp enables richer interactions. BulkSMSHub combines both in one omnichannel platform.

BulkSMSHub supports SMS delivery to 190+ countries with direct SS7 carrier connections. We have offices in UAE, Singapore, USA, UK, India, Australia, Saudi Arabia and Nigeria, with local compliance expertise in each market. Country-specific pricing and regulations are detailed on our individual country pages.

Omnichannel marketing coordinates customer communications across SMS, WhatsApp, email and other channels so every interaction is connected and personalised. Unlike multichannel (siloed channels), omnichannel shares customer data across all channels. BulkSMSHub's platform unifies SMS, WhatsApp and email in one dashboard with shared automation workflows.

Yes. All BulkSMSHub plans include a free trial with 500 SMS credits - no credit card required. You can test delivery to any of our 190+ supported countries before committing to a paid plan. Sign up takes under 2 minutes and you can be sending messages within 5 minutes.

BulkSMSHub supports promotional SMS (marketing campaigns, discounts), transactional SMS (order confirmations, delivery updates), OTP/2FA SMS (one-time passwords for authentication) and informational SMS (appointment reminders, alerts). Each type has different compliance requirements by country, which BulkSMSHub manages automatically.

Yes. BulkSMSHub supports Unicode SMS for all character sets including Arabic, Hindi, Chinese, Japanese, Korean, Thai, Swahili, Tagalog and all European languages. Unicode messages use 70 characters per SMS part (vs 160 for standard GSM encoding). The platform automatically detects the character set and applies correct encoding.

A custom sender ID (also called alphanumeric sender ID) lets you send SMS from your brand name (e.g. 'YourBrand') instead of a random number. This significantly increases trust and open rates. BulkSMSHub supports custom sender IDs in 100+ countries. Note: some countries (USA, Canada) do not permit alphanumeric sender IDs and require short codes or 10DLC numbers.

Yes. BulkSMSHub supports two-way SMS messaging, allowing recipients to reply to your messages. Replies appear in a shared team inbox where multiple agents can respond. Automated keyword responses (e.g. STOP for opt-out, INFO for information) are configurable. Two-way SMS requires a dedicated long code or short code number.

A short code is a 5-6 digit number used for high-volume A2P SMS campaigns. Short codes support higher throughput (100+ messages per second vs 1-10 for long codes) and are required for some use cases. BulkSMSHub provides dedicated and shared short codes in the USA, UK, Australia and other markets. Most businesses can use 10DLC long codes instead.

Yes. BulkSMSHub supports scheduled sending at a specific date and time, recurring campaigns (daily, weekly, monthly), trigger-based sending (when a contact joins a list, makes a purchase, or triggers a webhook event) and drip campaigns (multi-touch sequences with configurable delays). All scheduling uses the recipient's local timezone.

Yes. BulkSMSHub has a native Shopify integration that automatically sends order confirmations, shipping updates, delivery notifications and abandoned cart recovery SMS. Install from the Shopify App Store or connect via API. The integration supports Shopify Plus for high-volume merchants and includes WhatsApp notification support.

BulkSMSHub's analytics dashboard shows real-time delivery rates, open rate estimates (where carrier data is available), click-through rates for tracked links, opt-out rates, campaign ROI, geographic delivery breakdown and API usage metrics. Reports can be exported as CSV, Excel or PDF and can be scheduled for automatic email delivery.

Yes. BulkSMSHub supports merge tags including {first_name}, {last_name}, {company}, {order_number} and any custom field from your contact database. Dynamic content blocks allow different message variations based on contact attributes (e.g. different offers by country or customer segment). Personalised SMS achieves 20-30% higher CTR than generic messages.

DND (Do Not Disturb) filtering automatically removes contacts who are registered on national do-not-disturb registries from your campaign sends. This is mandatory for compliance in India (TRAI DND registry), UAE (TDRA), Australia (ACMA/AMCA) and other markets. BulkSMSHub applies DND filtering automatically based on destination country.

Yes, with proper consent and compliance. Different countries have different regulations: GDPR in Europe, TCPA in the USA, CASL in Canada, TRAI/DLT in India, TDRA in UAE, ACMA/Spam Act in Australia. BulkSMSHub automates compliance including opt-in management, DND filtering, opt-out processing and quiet hours enforcement for every supported market.

TCPA (Telephone Consumer Protection Act) is the US law governing commercial SMS. Key requirements: written prior express consent required for marketing SMS, quiet hours (8AM-9PM recipient local time), functional STOP opt-out within 10 business days, 10DLC registration for long code campaigns since February 2025, and SHAFT content restrictions. BulkSMSHub automates all TCPA compliance requirements.

DLT (Distributed Ledger Technology) is India's TRAI-mandated SMS compliance system. All commercial SMS senders must register their entity, sender IDs (headers) and message templates on the DLT platform. Unregistered messages are blocked by Indian carriers. BulkSMSHub manages the complete DLT registration process for customers sending to India.

10DLC (10-digit long code) is the US A2P SMS registration system mandated by the major US carriers since February 2025. All A2P SMS to US numbers must use 10DLC-registered long codes - unregistered numbers are blocked by AT&T, T-Mobile and Verizon. BulkSMSHub handles complete 10DLC registration including brand registration and TCR campaign registration.
