After Building Bulk Messaging, I Became More Cautious About It

Bulk messaging sounds like a straightforward productivity feature: write once, send to many people, and save a large amount of repetitive work. That was how I saw it when I first built the workflow for MSG.AI. Once I had a working queue, configurable delays, progress tracking, and pause-and-resume controls, however, my view changed. The technical problem was manageable. The harder problem was deciding when the feature should be used at all. The more reliable the tool became, the more important it felt to talk about restraint. There are legitimate reasons to message a group of customers Bulk messaging is often discussed as if it were synonymous with cold outreach. In real customer operations, that is not always true. A business may need to tell existing customers about a delivery delay. A salesperson may need to share updated documents with people who requested them at a trade show. A support team may need to notify affected customers about a service interruption. A supplier may need to communicate a holiday schedule to active buyers. These messages can be useful, timely, and expected. The repetitive part is operational. Opening dozens of chats, pasting the same update, checking names, attaching the right file, and remembering who has already received it creates room for mistakes. A task queue can reduce that mechanical work. But solving the mechanical problem does not answer the more important question: should this person receive the message? Consent cannot be implemented as a sending interval Developers like problems that can be represented as settings. If sending too quickly creates risk, add a delay. If identical timing looks unnatural, randomize the interval. If a task is too large, split it into batches. If the user makes a mistake, add a preview screen. Those controls are useful, but they do not create consent. A five-minute delay between unwanted messages still produces unwanted messages. Random timing does not turn an unknown phone number into an existing cu
