I need two things:
1. A way to check for invalid characters in a plain text file that contains a list of email addresses. Trying to upload list to a phplist mail program and can't.
If Microsoft Word or something can quickly scan for invalid characters in email addresses, let me know how to do it (step by step) and I will pay you for this information.
2. A way to validate email addresses so when a person fills out a form an email will automatically be sent to that person which contains a link for them to click. The link would then forward them to a specific page on a website while at the same time, adding that email address to a list of verified email addresses.
