I need a straightforward system that automatically sends job-related SMS alerts to subscribed users. The sole purpose is to deliver timely job notifications, keeping each subscriber instantly informed whenever a new vacancy is available. Here is what I expect: • A small, easy-to-maintain backend that lets me enter or upload new job listings and trigger the outgoing texts. • Subscriber management—add, edit, delete numbers, and quickly view current opt-ins. • Reliable SMS delivery with basic reporting (sent, failed). An API such as Twilio, Nexmo, or any carrier-grade alternative is fine as long as it is cost-effective and supports my region. • A simple opt-in/opt-out workflow. I am open to sign-up through a web form, a direct “REGISTER” text, or even a lightweight mobile app—whichever you recommend for speed and affordability. • Clear documentation so I can update job notices myself and comply with standard SMS consent rules. The project is purely about job notifications; no extra marketing messages or unrelated alerts are required. Clean code, concise instructions, and a quick setup are far more important to me than flashy UI. If you have prior experience building subscription-based SMS services, please mention it and highlight which SMS gateway you prefer.
