To implement encrypted connections in email marketing, follow these steps:
1. Choose a Reliable Email Service Provider (ESP): Ensure that your ESP supports SSL/TLS encryption. 2. Configure Your Mail Servers: Make sure that your mail servers are configured to use SSL/TLS for sending and receiving emails. 3. DKIM, SPF, and DMARC: Implement these email authentication protocols to prevent email spoofing and ensure the integrity of your messages.
