You can easily integrate SMS features using Celitix’s SMS API. Our developer-friendly API allows you to automate sending of bulk SMS, OTPs, and transactional messages directly from your website, CRM, or app. With detailed documentation and support, integration is fast and secure.
Bulk SMS refers to sending a high volume of messages at once, typically for alerts or notifications. Text marketing, on the other hand, involves more personalized, targeted messaging to engage customers, promote offers, or build loyalty. Celitix supports both — so you can communicate at scale or 1-on-1.
To run compliant SMS marketing campaigns, always obtain user consent before sending messages. Celitix helps you follow guidelines like DND (Do Not Disturb) filters, opt-out management, and time restrictions — especially important in countries like India where bulk SMS services are regulated by TRAI.
Yes! With Celitix’s bulk SMS platform, you can schedule campaigns for future delivery — perfect for sending messages at the right time, even if you're offline. Whether it's a marketing campaign or a system-generated alert, scheduling helps improve response rates and engagement.
SMS marketing can be used to re-engage customers who left items in their cart without purchasing. By integrating our SMS API with your e-commerce platform, you can automatically send reminder texts, discount codes, or limited-time offers — helping boost conversions and reduce cart abandonment.
