Hello @RusWilson,
Thanks for sharing your question with the Klaviyo Community!
Glad to hear you were able to custom code your own signup form! Because this is a custom coded signup form, its behavior and display would all be dependent on how you coded the form.
Since it sounds like there may be some fields within the custom form’s success message you want to adjust, I would recommend making edits to the custom form’s code that pertains to the success message with your desired outcome. I’ve also linked some resources below that may be able to assist you. For further assistance such as reviewing your custom form’s code and/or making the necessary edits to your code, I would recommend working with a developer you are familiar with or finding a Klaviyo partner.
I hope this helps!
David
