Presale Question - Email field in Accounts

Presale Question - Email field in Accounts

I'm in the process of migrating from another CRM platform.

I see that by default the Accounts section in Zoho does not inlcude an email field. You need to create a contact in order to enter an email address.

Our actual CRM platform can save multiple email addresses associated to the a single Account (and not to contacts), which makes sense since the company can have a generic address (eg. info@).
We normally put the generic email on the Account then we create contacts for real people.

How to do that in Zoho?

I can create a custom field but... will I be able to use that custom account field for sending mass mailings of for syncing with our mailmarketing app? Mailchimp.

Thanks!
