                    Suppression list types Add addresses to the Unsubscribed list Remove an address from a suppression list

                    Appcues won't send emails to addresses on a suppression list. Before sending your first Workflow email, add any addresses that have previously opted out of communication from your company so they don't receive unexpected messages.

                    Go to Settings > Emails > Suppression lists to manage all three lists.

                    Suppression list types

                    Unsubscribed — Addresses added here manually, via CSV upload, or automatically when a user clicks the unsubscribe link in any Appcues email.

                    Bounced — Addresses added automatically when an Appcues email can't be delivered (invalid address, full inbox, or server rejection).

                    Spammed — Addresses added automatically when a recipient reports an Appcues email as spam.

                    If a user's email appears on any of these lists, no Appcues email will be sent to that address.

                    Add addresses to the Unsubscribed list

                    Individually — Click Add, then enter one or more email addresses separated by commas.

                    In bulk — Click Upload CSV and upload a single-column CSV file containing the email addresses.

                    Bounced and Spammed lists are populated automatically and can't be added to manually.

                    Remove an address from a suppression list

                    Navigate to the suppression list that contains the address.

                    1. Click the vertical ellipsis (⋮) next to the email address.
                    2. Select Remove.

                    This works on all three list types. Use it when an address was added in error or when a user asks to be re-subscribed.
