Hi

I am using a marketing page (landing page) for external users to subscribe a newsletter.

i applied a unique key to email address for the Contact entity. However, when a user tries to re-subscribe with the same email, the user record is updated with the later selection instead of preventing with an error.

How i can make the Marketing page preventing the re-submission with same email.  

Thank you so much,

Siva

    HI Siva,

    Could I confirm some details of your requirement:

    How long would you like to prevent user to submit form with same email?

    You could use localStorage object to store previous email, at formSubmit event, read the value from ls object and compare whether it is equal to current email, if yes, then do event.preventDefault.

    However, it won't be cleared automatically unless users clear their browser cache, or we could set a expiration timestamp in ls object, the ls will be remove it when a specific time comes.

    Regards,

    Clofly
