Summary
CSA certification improves deliverability, especially in Germany, by adhering to strict technical (SPF, DKIM, DMARC, reverse DNS, SMTP compliance) and legal requirements, as well as a code of conduct. The application involves a technical audit and legal review. Double opt-in is recommended but not mandatory. Key to maintaining certification is a robust complaint management system, low complaint rates, and continuous monitoring of sender reputation. Violations lead to warnings, sanctions, or delisting. While focused on Germany, the certification can positively influence deliverability in other European countries. Small businesses should conduct a cost-benefit analysis considering resource investment versus potential deliverability gains. Experts emphasize careful consideration of CSA's criteria and potential non-compliance consequences.

Marketer from Email Geeks clarifies that Double Optin is a recommendation, not a requirement, to reduce spam complaints and ensure sending to the person who signed up. Also, one complaint will not directly lead to delisting; there are steps and levels of sanctions for recurring violations. CSA aims to showcase violations, not exclude senders, and recommends reviewing the CSA criteria. URL provided: <https://certified-senders.org/wp-content/uploads/2017/07/CSA_Admission_Criteria.pdf>
