What is transactional email?
Every hosting package comes equipped with email functionality. When emails are sent, most of the time they come from a personal or business email address like email@example.com or firstname.lastname@example.org. Alternatively, emails can also be generated from a website. For example, when a customer fills in a contact form, an email gets sent to both you and a copy gets sent to the person filling in the form.
All emails that are triggered based on a visitors action in a website can be seen as transactional (and not personal). You can think of account creation emails, password resets, purchase receipts, account notifications, and social media updates like friend and follower notifications. Transactional email is sent to individuals rather than a large list of recipients.
Why you should use a transactional email service
The primary purpose of a transactional email is to send information regarding the user’s action that triggered it. Compared to personal emails, the volume of transactional emails for a domain or website can be much higher, and therefore more sensitive to be flagged as spam. The bigger your website or webshop, the more emails you sent. If you would send a high volume over your hosting package’s email account, the risk you get flagged as SPAM increases.
