You can send emails with attachments from Nutshell, and any attachments on emails you sync with Nutshell will be visible from your company, person, or lead's timeline.
When composing an email to a company, person, or lead in Nutshell, click the paperclip icon to add an attachment.
You can also view your email attachments when you send an email message with an attachment from an outside email provider (Gmail, O365, or BCC) that is synchronized with Nutshell. The email and attachment are both visible in the individual’s timeline.
Due to general restrictions with email providers, Nutshell does not support sending bulk emails with attachments. You can do this through the MailChimp integration or another marketing automation provider.
The file size limit for email attachments is 5mb.
