To find code that actually works, you need to know the three architectural models for bulk SMS.

Create a recipients.csv with one column: phone (International format: +1234567890).

Never blast 10,000 messages on the first run. bulk+smssender+github+work

python sender.py --test --limit 5

Check delivery logs. If all 5 arrive, increase limit.

Before we dive into the code, you will need the following: To find code that actually works , you

A naive loop sending SMS one by one is slow. For true bulk (100k messages/day), you need concurrency.

Bulk SMS is heavily regulated. In the US, the TCPA requires prior express consent and an opt-out mechanism (e.g., "Reply STOP"). In the EU, GDPR mandates lawful processing of phone numbers. Using GitHub workflows does not exempt you from these rules. Sending unsolicited bulk SMS can lead to fines of $500–$1,500 per message. Always maintain a double-opt-in list and include clear opt-out instructions in every message. Create a recipients

Note: Always audit code before running. These are categories, not endorsements.

How to verify before cloning:

Create a new repository on GitHub. Inside the repo, create a file named sender.py. This script will handle the logic of reading contacts and dispatching the messages.
