You can upload a file of contacts to bulk unsubscribe from all of your emails. This is commonly done when you are moving to Sentori, and you need to load a list of contacts who have previously requested to be removed from your email marketing list.
There are three steps in loading a suppression list.
First you need to prepare a spreadsheet (or CSV file) that contains a single column of email addresses with the column heading 'Email Address'. You can then load that file from contacts/suppression lists. You can browse for the file and load it into Sentori.
Having loaded the suppression list you will get a report. Review the numbers and confirm that they are correct.
If you are happy with the information shown then taking the green 'Suppress Email Addresses' button will finally load the suppression list. If you take the 'Cancel' button Sentori will take no further action and the uploaded contacts will not be suppressed.
