Effective SMS Campaigns: From Intrusion to Relationship

In an era of overloaded email inboxes, SMS remains the most effective channel for direct customer reach. However, the line between a valuable notification and annoying spam is very thin. Here is what's changing and what you can do better.

Effective SMS Campaigns: From Intrusion to Relationship

What's changing right now

Mass generic blasts to purchased lists are becoming obsolete due to carrier filters and increasing consumer legal awareness. Today, transactional and behavioral communication—SMS sent in response to specific events—is what counts. Customers expect the ability to opt-out as easily as they opted in.

What you can do better

Concretely, starting today

  • Contextual personalization: Instead of 'We have a sale', write 'Your favorite items are 20% off today'.
  • Ensure a clear Sender ID: Use your brand name as the sender to build trust from the very first second.
  • Include an opt-out link: A transparent 'unsubscribe' mechanism protects your list from spam reports and GDPR fines.
  • Optimize delivery timing: Avoid late nights and early mornings; test times when your customers are most likely to use their phones.

Najczęstsze pytania

Do I need separate consent for SMS?

Yes, according to GDPR and electronic services regulations, consent for marketing via phone must be voluntary and explicit. It cannot be pre-checked by default.

Why did my SMS end up in the customer's spam folder?

Common reasons include missing Sender ID, using low-reputation link shorteners (like bit.ly), or overusing caps and exclamation marks. Modern Android and iOS systems actively filter such content.
