Bulk SMS services allow businesses to send large volumes of text messages simultaneously to a broad audience. These services are typically used for marketing campaigns, alerts, notifications, and reminders. The messages can be promotional (e.g., for discounts or offers) or transactional (e.g., confirmations or OTPs).

Key benefits of bulk SMS include:

1. High Open Rates: SMS messages have a much higher open rate compared to emails.
2. Instant Delivery: Messages are delivered almost instantly.
3. Cost-Effective: It’s relatively affordable, especially when sending to a large audience.
4. Targeted Marketing: Messages can be tailored to specific segments of an audience.
5. Wide Reach: Almost everyone has a mobile phone, so the potential audience is vast.

Bulk SMS platforms typically offer features like scheduling, personalization, and tracking delivery reports, helping businesses optimize their communication efforts.
