The exception shows a problem (which I don't understand) that appears to be related to pytest and possibly the idna package that this library uses, so I don't think the problem is in this library.

[verhovensky]

But I had idna & pytest in my dependencies earlier and nothing happened. Just after installing email-validator I face the error. Nevertheless It's up to you to close the issue, thanks for the feedback!

[JoshData]

Maybe your version of idna changed?

[JoshData]

I'm going to close the issue because I don't understand what pytest is doing so I don't have any hope of figuring it out (in a reasonable amount of time). Feel free to re-open or comment if there's anything specific I can do.
