In a world saturated with marketing messages, Bulk SMS continues to stand out as one of the most effective, affordable, and direct channels for businesses to reach their audience. Whether it’s a small business promoting a weekend sale or a large enterprise sending transactional updates, SMS marketing offers unmatched immediacy and engagement.
What is Bulk SMS?
Bulk SMS refers to the process of sending a large number of SMS messages to a targeted group of recipients at once. These messages can be promotional (e.g., discounts, offers, event invites) or transactional (e.g., OTPs, alerts, appointment confirmations).
Unlike email or social media, SMS messages have a 98% open rate, and most are read within 3 minutes of receipt. This makes SMS marketing an incredibly powerful tool for time-sensitive campaigns.
