You can access these settings in the Settings application under the On-line marketing -> Email marketing category.
Unsubscription page URL
Sets the URL of the page where users can unsubscribe from an email feed. The value of this setting is inherited by individual email feeds if their Unsubscription page URL property is not set.
The specified page must provide the required unsubscription functionality (on MVC sites developers need to create a page that handles unsubscription, on Portal Engine sites the page must contain the Email feed unsubscription web part).
If empty, the ~/CMSPages/Unsubscribe.aspx default page is used (only works for Portal Engine sites).
Double opt-in approval page URL
Sets the URL of the page 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 page must provide the required subscription confirmation functionality (on MVC sites developers need to handle the subscription confirmation, on Portal Engine sites the page must contain the Subscription approval web part).
If empty, the ~/CMSModules/Newsletters/CMSPages/SubscriptionApproval.aspx default page is used (only works for Portal Engine sites).
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.
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 checked, 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.
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.).
Specifies the number of the port used to connect to the mail server.
Sets the user name used for authentication against the mail server.
Selects the authentication mode used to connect to the mail server. The options are:
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).
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.
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.
