Good morning everyone,
i’m starting using this wonderfull plugin last week and i’ve nearly finished to install it in my wordpress.
My last customization is to implement an email validation that check if the email submitted is already saved in my susbscriber list. I just need to add an error to email input that tells that the email is already taken, similar to the “email not valid” error. I’ve already see that, if i submit an email already in the db the plugin update the infos previous submitted, but this is not what i need.
Unfortunally i don’t know how to start to add this feature, can anyone describe me the steps and what file edit?
Thanks so much and good work everyone!
