Configuración de notificaciones por email con MailChimp

I am looking for help setting up email notifications with Mailchimp for a new enterprise. I already have a Mailchimp account, so a good working knowledge of the program is essential. The project needs to be completed within a month, but the sooner it is done, the better. I need a reliable professional whom I can count on to finish the project in a timely fashion and with top quality work. If this meets your expertise, I’d love to hear from you.I need to correctly configure the CNAME, MX etc. records of the domain verified through Mailchimp. Currently I can't receive the notifications that the application sends me, when registering, different events, etc. in the inbox. I have already correctly configured the domain that was correctly verified and the records corresponding to the DKIM and SPF methods. I have a paid Mailchimp account.
