Your contact list is your most valuable marketing asset — but only if it is built the right way. Here is how to grow a permission-based SMS list and manage it in Pak Sender.
Start with Opt-In
Always collect numbers from people who agree to hear from you. Opt-in keeps your list legal, your delivery healthy, and your brand trusted.
Where to Collect Numbers
- At checkout, in-store or online.
- Through a sign-up form or newsletter.
- With a keyword opt-in ("Text JOIN to…").
- In exchange for a discount or useful content.
Keep the List Clean
Remove invalid and inactive numbers regularly. A clean list improves delivery and lowers cost by cutting wasted sends.
Respect Opt-Outs
Make it easy to unsubscribe and honour every request promptly. Respecting choices protects your reputation and keeps engaged customers engaged.
