Mass mail to list of emails

Mass mail to list of emails

Dear Zoho CRM Team,

We have a list of emails of our potential customers and would like to send them our quotes, but we don't want to create leads/potentials for each of them.

Is it possible somehow to send our quotes to them using some functionality of Zoho CRM?  Just a plain email, but to hundreds of recipients?

Is it's not possible then question is how to do that for our already registered customers? I see Campaigns menu in CRM, but can't find there any way to send mail with attachments, for example.

THank you.
