 * Hello,
    I am working on adding MailPoet support to my validation plugin, I’ve
   been looking through your documentation but I do not see anything specific to
   custom validation. Is there a filter available for adding content before the 
   submit button or testing custom validation before the form is submitted?

 * I have an Image CAPTCHA plugin (All-In-One Image CAPTCHA Pro) that I would like
   to add MailPoet support to

 * The All-In-One Image CAPTCHA Pro is an alternative to Google ReCAPTCHA which 
   harms web site performance.

 * Hi there [@ktc_88](https://wordpress.org/support/users/ktc_88/),
 * I checked with our developers and we don’t have such filter in the plugin’s code.
 * However, it might be possible to add it with some custom code. If you need help
   with custom code, you can reach out to someone from Codeable: [https://codeable.io](https://codeable.io).
 * Cheers!
