Numerous emails to external entities from zoho crm

Numerous emails to external entities from zoho crm

Hi,

I have a question that I would like to be answered.

I need to set up different emails, for pre-determined dates, to be sent for external users (could be CRM contacts).

Example:
you're a teaching enterprise and you need to send emails in defined dates to your students - 3 emails per week, for 5 weeks (15 different emails). Each email has to be sent to various students at the same time.

Activities only lets you set up recurrent activities to crm users, not external entities.

Could you please help me?

Thanks in advance.
