SMS marketing is revolutionizing French customer engagement with an open rate of 99%, 90% of which are opened within 15 minutes. In 2024, brands sent 14.2 billion SMS messages in France, a 6% increase compared to 2023, confirming the exceptional effectiveness of this direct channel.
This remarkable performance can be attributed to the immediacy and universality of SMS: unlike emails, which can be intercepted by spam filters, SMS directly reaches consumers without the risk of getting lost in an information overload. However, fully leveraging this potential requires in-depth technical expertise and a perfect understanding of strict French regulations.
