Please What is your Python Version Try Updating your python and kali Linux in General if you are not on latest Version
For Updating Kali
sudo apt update && sudo apt upgrade
Check Python version using
python --version
latest version now is 3.10.4

A bit late reaction, but for people who encounter this problem in the future.

pip install validate_email

or for python3:

pip3 install validate_email
