There are several reasons why email marketers should use HTTPS:
Security: HTTPS helps protect sensitive information such as login credentials and personal data from being intercepted by malicious actors. Trust: Using HTTPS can enhance the trustworthiness of your brand. Recipients are more likely to open and engage with emails from a secure source. Compliance: Many regulations and standards, such as GDPR, require the use of secure communication methods to protect personal data. Deliverability: Some email service providers prioritize emails from secure sources, improving your chances of landing in the recipient's inbox rather than the spam folder.
