How can we improve WHMCS?

Summary:
WHMCS's current integration with MailChimp doesn't account for the user's language preference, resulting in less personalized email campaigns. This feature request proposes an enhancement to sync the user language from WHMCS to MailChimp.

Problem Statement:
While the existing integration between WHMCS and MailChimp is highly functional for various marketing activities, it lacks the ability to consider the language preferences of users. In a multi-lingual customer base, this oversight can lead to less effective communication and decreased customer satisfaction. Sending emails in a language that the customer doesn't prefer can be a missed opportunity to connect and may even frustrate users.

Proposed Solution:
Enable WHMCS to sync user language preferences to MailChimp. This information could be used in MailChimp to send personalized, language-specific email campaigns, significantly improving customer engagement and satisfaction.

Example:

User A has a language preference for Spanish in WHMCS.
Upon syncing with MailChimp, this preference is carried over.
User A receives email campaigns in Spanish, thereby improving their user experience and increasing the likelihood of engagement.
Benefit:
Incorporating language preferences into the MailChimp sync would allow for a more tailored and effective email marketing strategy. This not only enhances user engagement but also builds trust and satisfaction among your customer base.
