Suppression List Explained
A suppression list is a list of email addresses to that you don’t want to send emails. These email recipients are added to the suppression list for many reasons.
Either the email addresses are invalid or they have unsubscribed from your email list. If you will keep contacting these recipients, your sender’s reputation will be greatly affected and your domain will be at high risk of being blacklisted by the ISPs.
For example, if you have some hard-bounced email addresses in your list, and you will send messages to them, what will be happened ultimately? There is hardly any need to comment on it.
CAN-SPAM Act doesn’t allow you to send emails to recipients who are not interested to read more content from you. Hence, they required a suppression list that receives invalid, bounced, or blocked emails.
According to CAN-SPAM Act, if a recipient unsubscribes from your email list, he has to be added to the suppression list. It will help them not receive any emails from you.
What Is an Email Suppression List Used for?
In email marketing, a suppression list is of much importance because it ensures sending your message to the interested audience only. It further helps you maintain your domain and IP reputation.
Again, if you will not distance yourself from the opted-out users, you will be facing the CAN-SPAM Act of 2003 which gives liberty to the recipients either to receive emails from you or not.
What Should Be Included in the Suppression List?
There are various types of emails that you need to suppress immediately or before sending an email campaign.
Let us discuss them one by one:
Users Who Marked You as Spam
Do not wait to add email addresses to the suppression list who have marked/reported your emails as spam. People report your emails due to certain reasons.
One of the top causes in this regard is that they do not find a clear unsubscribe link or button when they wanted to opt out. Likewise, there might be some users who have already unsubscribed from your email list but you still send them emails.
These least interested users will take no time to report you as spam. If you do not care about these issues, it is just like axing your foot in form of spoiling your IP and domain reputation.
Once the graph of your reputation went down, you will be having minimum chances to land in the mailbox of the users.
Contacts Who Have Opted Out
As long as you maintain to send the relevant content to the users, they will remain intact with you. The moment they find anything inappropriate, they will take less than a minute to unsubscribe from your email list.
Once they unsubscribe from your list, do not send them any emails rather add these email addresses to the suppression list. It will help you not send any emails in the future even mistakenly.
When you use Mumara, you get real-time results of your email campaigns including the activity of the users i.e., open & click-through rate, unsubscribe, or spam complaints.
If you are unable to track these users and will send them the emails unknowingly, get ready for the poor reputation and deliverability.
Hard Bounced Email Addresses
A hard bounce occurs when an email address doesn’t exist. Mostly, we see this issue when there is a typo if someone provides the email address.
As soon as you get a hard bounce, suppress it and remove it from the email list. Otherwise, get ready to face the email deliverability issues. It will damage your reputation and signal the ISP that your email list is not hygienic.
If this happens, it will become difficult for you to land in the mailbox. The best practice to avoid these issues is to suppress these contacts immediately before facing any disastrous situation.
Disengaged or Inactive Users
This is an open secret that some users become passive over time due to some reasons. They stop opening your emails which makes them disengaged from your message.
If there are such kinds of users in your email list, suppress them as inactive or disengaged users. But the question that how to find disengaged or inactive users.
For that purpose, you need to use Mumara to eye on the real-time stats. You can decide the users to add to the suppression list based on the activity.
For example, you can set a policy for yourself to watch out for the users for 30 days, and if they are not opening up your emails, you can add them to the suppression list.
