Settings - Email marketing

You can access these settings in the Settings application under the On-line marketing -> Email marketing category.

General
Unsubscription page URL	Sets the relative URL path on your live site where users can unsubscribe from email feeds. The value of this setting is inherited by individual email feeds if their Unsubscription page URL property is not set. The specified URL needs to handles unsubscription requests. Example: ~/Newsletter/Unsubscribe
Double opt-in approval page URL	Sets the relative URL path on your live site where users can confirm their subscription to an email feed with double opt-in enabled. The value of this setting is inherited by individual email feeds if their Approval page URL property is not set. The specified URL needs to handle subscription confirmation requests. Example: ~/Newsletter/ConfirmSubscription
Double opt‑in interval	Sets the length (in hours) of the time interval during which users will be allowed to confirm their subscription to an email feed that uses double opt‑in. If a user does not activate their subscription within the specified number of hours, the link in their confirmation email expires and becomes invalid.
Generate marketing emails if emails are disabled	If enabled, marketing emails are generated and saved into the Email queue even if sending of emails is disabled in Settings -> System -> Emails.
Bounced emails
Monitor bounced emails	Indicates if bounced emails should be tracked for marketing email recipients. Bounced emails are received whenever there is a problem with the delivery of a marketing email to a contact.
Bounced email address	Sets the address to which bounced emails are sent when the delivery of a marketing email to a recipient fails. If set, this address is used in the From field of marketing emails.
Bounced email limit	Sets the amount of bounced emails that can be counted for a recipient before the system blocks them from receiving further emails. This limit is set for all email feeds under the selected site. If 0 is entered, recipients will never be blocked automatically, but their bounced email count will still be tracked and displayed in the Email marketing application.
Block recipients globally	If enabled, bounces will be added to all recipients that have the same email address. This is applied across all sites in the system. Note: This setting does not ensure consistency between the bounce counts of all recipients with a shared email address, only that new bounces will be added to all of them. This field is only available when defining global settings, i.e., when the (global) option is selected from the Site drop-down list.
POP3 settings
Server name	Sets the domain name or IP address of the mail server where bounced emails are stored. POP3 is used to check the server and monitor bounced emails. The connection automatically uses the HTTPS protocol if supported by the specified server. The system also automatically chooses the most secure authentication mechanism supported by the server (NTLM, SCRAM, MD5, Plain, etc.).
Server port	Specifies the number of the port used to connect to the mail server.
User name	Sets the username for authentication against the mail server.
Authentication type	Selects the authentication mode used to connect to the mail server. The options are: Basic (username + password) – uses Basic authentication. Fill in the User name and Password settings. OAuth 2.0 – uses OAuth 2.0 token-based authorization. Fill in the User name and select valid OAuth credentials. Many mail services are deprecating support of basic authentication, leaving OAuth as the only viable authentication type. A notable example is Microsoft Exchange Online, which begins disabling basic authentication after October 1, 2022 (see Deprecation of Basic authentication in Exchange Online).
Password	Only applies when the Authentication type is set to Basic. Sets the password used together with the User name when connecting to the mail server.
OAuth credentials	Only applies when the Authentication type is set to OAuth 2.0. Selects the OAuth credentials used for authentication. You can create and manage the credentials in the Email OAuth credentials application. See OAuth for email servers.
