Sender IDs need registering
Nigerian networks require a registered alphanumeric sender ID, and unregistered traffic gets filtered or dropped. We register yours with the networks so your messages arrive as your business name rather than an unknown number.
Do not confuse promotional with transactional
Transactional messages, codes, reminders and receipts, are expected and land well. Promotional blasts to purchased lists get complaints, and complaints get your sender ID blocked. NDPR also applies: you need a lawful basis to message someone.
Use it as a fallback, not a strategy
The best pattern is WhatsApp first, SMS if undelivered after a set time. DMly does that automatically, so you only pay for SMS on the customers who genuinely needed it, which is usually a small share of your list.
Timing matters more than copy
A reminder at 8pm the night before beats one at 6am on the day. A restock alert on a Friday afternoon beats Monday morning. Schedules in DMly respect West Africa Time, not a server in Virginia.
