Show Blog Subscribe Option Only to Non-Subscribers (Personalization)

[Anonymous]

Hello Marketo Nation!

We're looking at implementing a solution on our blog page that accomplishes the following function:

• Show the blog subscriber option to opt-in only if a website visitor is not included within our Marketo List for Blog Subscribers.
• If the website visitor is already included within the Marketo List for Blog Subscribers then they will not be shown the option to subscribe once again.

End goal: Only non-blog subscribers will be shown the option to subscribe to our blog.

Thanks in advance everyone!

You can't directly look up in a list, but if you mirror the list membership to a boolean field (switch true/false as lead moves in/out of list) then you can output that {{lead.token}} in the LP, and in turn use it to decide whether the form should be shown.

Better yet, use a datetime instead of a boolean, since it supplies richer information (blank == not in list, non-blank == when they were last added to the list) than a boolean.
