[Help] Auto Link Clicking in Gmail Account

Hello,

I have hired a freelancer to create a script that goes into my gmail account, switches to gmail HTML (minimal), finds a specific email, opens it, and then clicks a confirmation link.
However it gets to the opening of the email and then crashes. It wont click the confirmation link and we can't figure out why. Does anyone have any idea on how to script this or have anything I can potentially pass on to my freelancer?

*I have very minimal programming knowledge.

Thank you!

If you shared the exact error that's happening I/(we) might be able to help. Either way I do believe using a browser to access this email is pretty damn backwards. Gmail and many other email providers allow POP3/IMAP access, google something like "your_favourite_language IMAP receive email" and you are guaranteed to find open source libraries that help you receive email-headers directly in code, which is obviously ten times easier and more consistent than trying to do this through a browser. Maybe you should look into hiring a better freelancer
