Transactional emails are usually triggered based on a customer's action with a company. To be qualified as transactional or relationship messages, these communications' primary purpose must be "to facilitate, complete, or confirm a commercial transaction that the recipient has previously agreed to enter into with the sender" along with a few other narrow definitions of transactional messaging. Triggered transactional messages include dropped basket messages, password reset emails, purchase or order confirmation emails, order status emails, reorder emails, and email receipts.
If you want your audience to remain engaged with your content, you need to make sure you’re offering something of value. For some readers, that means offering a special discount or an exclusive promotion to your email list. For others that could mean offering a how-to article from your blog or a piece of content that’s more than just the typical sales pitch.
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.
