"Already Subscribed" message

If someone subscribed to my site for the 20% discount on their first order, does klaviyo recognized this same email address and prevent this person from subscribing again to get another 20% discount coupon in their email?  I have been on sites that use Aweber that says that I’m already subscribed.  Does Klaviyo also generates similar message when someone is already subscribed that has already received my signup discount code?

    Hi @jess,

    Thank you for sharing your question with the Klaviyo Community. And thank you @forman for your input.

    We will not prevent a user from re-entering their email address into a sign-up form multiple times, nor do we post a notice that a user has already subscribed. However, we only allow profiles to pass through a list or segment triggered flow once. Therefore, if they were to sign-up multiple times, we would still only process them through the flow once. This will prevent them from receiving the code multiple times. 

    Thanks and have a great day.

    I can’t believe it’s been years and this has not been solved yet..It should be so simple: before subscribing someone, check Klaviyo’s DB and see if the email is already used. If it is, show a Failure error. This is not hard to implement - I am an IT architect and I know this is easy. In regards to privacy issues, it’s no different from any other system that says “this email is already in use...” So… What;s the issue here? I have customers saying they subscribed (again, unbeknownst to them) and were really upset (rightly so) because they could not use the free shipping promised. This hurts us ...
