Getting a number restricted is a real setback. Once a carrier or a messaging app decides you are sending unwanted volume, they do not care whether you meant well. The lesson is worth learning before it happens, not after.
Match the channel to the moment
Different channels carry different risk for a first, cold contact:
- A phone call is the safest first touch. Nobody bans you for calling, and a real conversation converts far better than a message.
- SMS works well if you keep the volume sensible and always offer a clear way to opt out.
- Email is fine for limited access businesses, kept low volume from a warmed address.
- WhatsApp is for after someone has replied, not for first contact. Cold WhatsApp to people who never opted in is the fastest way to get a number restricted, manual or not.
Volume is the thing carriers watch
A brand new number that suddenly sends hundreds of messages a day looks exactly like a spammer, because that is what spammers do. The fix is to warm up slowly. Start low, watch your opt out rate, and only raise the volume when the number has a track record and the message is actually landing.
Keep your opt out rate low
The single number to watch is how many people opt out of what you send. If a lot of people are opting out, that is the market telling you the message or the targeting is wrong. More volume will not fix that, it will just get you flagged faster. Fix the message first.
Make it easy to say no
Always give people a simple way out. A clear opt out keeps you honest and keeps your number healthy. Someone who quietly opts out is far better for you than someone who reports you.
Write like a person
The messages that get replies are short, specific and human. Use the business name, say something true about their situation, and ask a genuine question. Skip the corporate phrases. If it reads like a template blast, it will be treated like one.
Site Pounce is built around these guardrails on purpose: paced sending inside sensible hours, a per day cap, an automatic pause if your opt out rate climbs, and a soft opt out link so people can leave without it counting against you. The point is to keep you sending for the long run, not to squeeze one big blast and then go quiet.
