Opt-in: why is it important (GDPR)

1. What is opt-in?

Opt-in is the explicit consent given by a user to receive communications or to have their data used for a specific purpose.

This means that the user has actively chosen to say “yes” to a specific action, such as receiving a newsletter, being targeted by advertisements or being included in a marketing database.
In the absence of an opt-in, any use of the user's data is generally prohibited, in accordance with data protection regulations such as the GDPR (General Data Protection Regulation).

The opt-in is crucial for several reasons:

Legal compliance

In many regions, including the European Union, the GDPR imposes the obligation to obtain clear consent before collecting or using personal data.

Credibility and trust

Users who give their consent are more likely to engage with your campaigns.

Better marketing performance

An opt-in database is made up of contacts who are genuinely interested in your content, products or services. This optimizes :

E-mailing campaigns (newsletters): higher open and click-through rates.
Creation of advertising audiences: precise, committed segments for better-targeted, more effective campaigns.
Use of data: exploit relevant information to personalize your messages, improve your offers and anticipate your audience's needs.

Strategic use of data

With a clear opt-in, you can use data legally and ethically.
