2. Why Remove Bounced and Unsubscribed?
Every email service provider uses your Sender Score to filter
emails and determine your inbox placement rate.
Keeping sending to bounced and unsubscribed emails would
lead to high bounce rate and spam complaints of your email
campaign. Such behavior is harming the email ecosystem, thus,
it will seriously lower your Sender Score.
Therefore, constantly removing bounced and unsubscribed
emails from your contact list is very important to your email
deliverability and future revenue stream.
In this guide, you will learn how to look for characteristics (e.g.
senders, subjects, keywords) of bounced and unsubscribed
emails through POP3 settings of your email account, and how
to clean them up.
