Attachments can be sent along with your email campaigns. Simply create a new campaign and navigate to the editing screen. The small gray paperclip next to the subject line field will allow you to select which files to add.
After clicking the paper clip, you can browse your computer to find the image or file you intend to attach to your email.
Finish customizing your email as you typically would, and send. Some email service providers block attachments or emails with attachments, so be sure the list you’re sending to is familiar with your email address and has added it to their address book to ensure they will receive your message.
