Can I add a GitHub Pages domain for EmailJS on the free plan?

[Nikzr0]

Hello,

I’m using the free plan of EmailJS and integrating it into my website hosted on GitHub Pages. The form works well locally but returns a 405 error when deployed on GitHub Pages. I believe I may need to add my domain to the EmailJS dashboard, but I can’t seem to find an option to do so. I noticed a field in the site's HTML that might be relevant, but it seems to be inaccessible for free plan users.

Could anyone clarify if I need to add the domain there or if there’s another cause for the issue? Any advice would be greatly appreciated!

Thanks in advance!
