A blast email is a type of electronic mailing that is distributed to a large recipient list, and is sent out over a specified amount of time. Often used by marketers, these types of bulk emails were once considered a form of spam, or junk email. Many companies now use blast emails as a legitimate tool to communicate with their customers, and as a result, blast email has become an effective type of email marketing.
Note: If you want to attach additional files, such as a .pdf, we recommend that you store these files on a cloud storage service, such as Dropbox or Google Drive, and linking to these files within your blast. We do not support file attachments to an email blast as these file types tend to be larger, increasing your chances of triggering spam filters and preventing your blast from reaching your recipients.
