Disabling your newsletter subscription success email can be very crucial for many Magento 2 store owners. As with any form, any email address can be entered into the newsletter signup form as long as it matches a valid email format. However, Magento does not check the email address to see if it has a valid DNS record. This of course can wreak havoc on your email bounce rate. In this tutorial, we will show you how to disable the newsletter confirmation email in Magento 2 to prevent high email bounce rates.

What is an email bounce rate

An email bounce rate is calculated by the percentage of successful emails sent against those that returned a hard or soft bounce back to the server. In this article, we are mainly focused on lowering the hard email bounce rate. If you would like to learn more about hard and soft email bounces, please feel free to read this article.

Why should I care?

Most hosting companies, SMTP providers and/or marketing agencies will penalize you if you have a high email bounce rate by limiting the number or emails being sent over a specific amount of time or even by stopping all outgoing emails from your server or marketing platform for a period of time. For example, AWS expects all users using their Simple Email Service (SES) to maintain an email bounce rate of 5% or lower. Those who reach a bounce rate of 10% or more will likely receive an email sending pause.
