Double Opt-In

Double Opt-In and Opt-Out

Double Opt-In/Opt-Out is a common mechanism to minimize the false addition/removal of addresses from your mailing list. It requires the user to confirm the subscription or removal of their address to the mailing list by replying to an email.

Users must confirm their subscription to the mailing list

When a user attempts to subscribe themselves to your mailing list a message is sent to them which they must reply to in order for the address to be added to the mailing list.

Click the Edit button to change the text of the confirmation message.

Users must confirm their removal from the mailing list

When a member attempts to unsubscribe themselves to your mailing list a message is sent to them which they must reply to in order for the address to be removed from the mailing list.

Click the Edit button to change the text of the confirmation message.

Note:

You can disable opt-in for specific groups or customize the message that is sent by selecting File > Options, Edit Group, Messages tab
A tag will be added to the subject line (e.g. MLK-ID:12345) to enable MailList King to track the message
The %RESULT% field can also be used to insert the tag into the message body (however the tag in the body will not be processed in any way)
You can view all opt-in/opt-out requests that are awaiting confirmation by selecting "Pending Double Opt-In" mode (under "History" in the main window)

Options

Send a reminder message after x days

If a user has not confirmed their subscription/removal within the specified number of days, MailList King will send a reminder message (a reminder message is the same as the message specified above, but contains REMINDER in the subject line)

Automatically delete confirmation records that are not confirmed within x days

You can automatically delete opt-in/opt-out requests after a specified time period by setting this option.
