If you use Bitrix24 on-premise, we encourage you to try a new MailChimp Integration module, developed by YouNet SI, one of the leading Bitrix24 partners in Vietnam & S.E.A.
The Newsletter MailChimp Integration module allows Bitrix24 users to take full advantage of all MailChimp newsletter functions directly from their Bitrix24 system interface.
You can find more information about this module on YouNet Si blog. If you have any questions or interested in installing the module please contact YouNet Si directly.
