A suppression list consists of email addresses that you want to exclude from your deliveries, because sending to these contacts could hurt your sending reputation and delivery rates.
It gathers email addresses and domains that are suppressed across all mailings in a single client environment, meaning specific to an organization ID associated with a sandbox ID.
To control the email messages that are received by their inbox owners and ensure they only receive those they want, Internet service providers (ISPs) and commercial spam filters have their proprietary algorithms to track the overall reputation of email senders based on the IP addresses and sending domain(s) they use.
If you do not take their feedback (such as spam complaints, bounces, etc.) into account, they will rate your reputation down. The suppression list helps you with honoring the ISPs' feedback.

Sending to recipients after they submit a spam complaint may have a huge impact on your sending reputation, because it informs ISPs that you may send unwanted emails and may not listen to your recipients.
This could lead to your IP address or sending domain being blocked, which can be avoided with these addresses being on the suppression list.
