When you use Double Opt In in a Kulea form, you must include a particular link for the subscriber to click and become validated... here is the full how-to on:  creating custom double opt in emails

You can now customise that link to say whatever you want it to! 

Whilst the [[validation_link]] shortcode still works, we've now created a new shortcode that allows you to insert whatever text you like into the validation link to make it a bit more user friendly.  Simply wrap the text (something like "sign me up today!" works a charm) in the following shortcodes and insert them into your double opt in email content: [[validation_link_start]]sign me up today![[validation_link_end]]
