Bulk SMS Campaigns Powered by Twilio
Send personalized SMS and MMS campaigns at scale through your own Twilio numbers. Smart scheduling, round-robin number rotation, message variations, auto-pause, DND enforcement, and real-time delivery tracking — all in one dashboard.
The Problem
Running Bulk SMS Through Twilio Directly is Complex
Twilio's raw API is powerful but requires custom code to handle queuing, rate limiting, scheduling, DND enforcement, MMS image management, delivery tracking, and opt-out processing. Building that infrastructure takes weeks of engineering time.
NumeraLoop provides a ready-made campaign layer on top of your Twilio account — giving you enterprise bulk SMS features without writing a single line of code.

Frequently Asked Questions
What is a bulk SMS campaign in NumeraLoop?
A bulk SMS campaign lets you send a personalized SMS or MMS message to a large list of contacts at once, via your own Twilio phone numbers. You control the message, the timing, the recipients, and the sending numbers.
Can I send MMS as well as SMS?
Yes. NumeraLoop supports both SMS (text only) and MMS (with images) campaigns. For MMS, you can upload an image and optionally add a personalized text overlay.
How many messages can I send per campaign?
There's no hard limit in NumeraLoop — your campaign volume is limited by your Twilio account capacity and balance. NumeraLoop queues and sends messages through your Twilio numbers respecting Twilio rate limits.
What is message variation rotation?
Message variation rotation sends slightly different versions of your message text across recipients. This reduces duplicate-content filtering by carriers and can improve deliverability for large campaigns.
Does NumeraLoop handle opt-outs automatically?
Yes. NumeraLoop automatically detects STOP replies and adds those numbers to your DND list, preventing future messages to opted-out contacts across all campaigns.
