A suppression list is a database that contains a list of email addresses or phone numbers that you do not want to send messages to. In email marketing, this list is used to avoid sending messages to people who have previously unsubscribed or marked your messages as spam.
Suppression lists are important in email marketing because they enable companies to comply with regulatory requirements regarding email communications. Additionally, using suppression lists can help maintain a good sender reputation and reduce the likelihood of being marked as spam by recipients.
To create a suppression list, you need to compile a list of email addresses or phone numbers that you do not want to send messages to. This can be done manually by reviewing your email records and marking the addresses that have unsubscribed or marked your emails as spam. Alternatively, you can use an automated system that tracks opt-outs and automatically adds them to your suppression list.
In ad tech, suppression lists can be used to exclude certain audiences from seeing advertisements. For example, if you are running an ad campaign targeting new customers, you may want to exclude existing customers from seeing the ads. This can be achieved by uploading a suppression list of existing customers to the ad platform.
Suppression lists can be used in SEO and content marketing by excluding certain topics or keywords that are not relevant to your target audience. For example, if you are writing blog posts about digital marketing for small businesses, you may want to exclude topics related to enterprise-level marketing strategies.
Some best practices for using suppression lists include regularly updating the list with new opt-outs, ensuring that the list is accurate and up-to-date, and using the list to improve your overall email deliverability and sender reputation.
