You can attach a file when sending replies in Unibox. Here are the steps:
Open the email you wish to reply to and click "Reply".
Click the "Attach Files" button, which is located next to the "Send" button.
Upload the file from your computer.
Once you've attached your file(s) and composed your email, click the "Send" button to deliver your message along with the attached file(s).
You can view and download files received from your leads directly in the Unibox threads—there's no need to log in to separate mailboxes to access the files.
However, attachments you sent from Unibox cannot be downloaded within Unibox.
