How does double opt-in work for certain countries?

Double opt-in requires users to confirm their subscription twice for added security and compliance.

Double opt-in ensures full compliance with GDPR and other strict privacy regulations in countries like Germany, Switzerland, and Austria, where data protection laws are particularly stringent and closely enforced. 

All contacts that legally require a double opt-in will automatically receive a follow-up email and will only be considered a viable marketing lead once they've clicked the specified link in the follow-up email.

• What regions do you run campaigns in?
• Can I run campaigns in different languages?
