Understanding the difference between bulk SMS and email marketing
In Europe’s dynamic digital landscape, businesses seek the most effective ways to connect with their audiences. Bulk SMS and email marketing are two long-established channels, but which one truly delivers better results for your campaigns? Here, we provide a deep dive into both, helping you choose the right tool for your goals.
What is bulk SMS marketing?

- Ideal for lengthy announcements or newsletters
- Supports multimedia and longer messages
- Broad analytical tracking (open/click rates)
- Can be automated and highly personalized
