is it easy to crack emails?

i was wondering, is it easy to crack emails such as @outlook @gmail @yahoo etc?

It depends on how good your password list is and if the have 2FA on their email.

It depends on multiple factors:
* Are logins rate limited?
* Do you have to enter a captcha after multiple failed attempts?
* How long is the password?
* Is the password complex?
* Is the account protected with 2-factor auth.
* What other security measures are in place?

If you have the ability to defeat the factors easily then the answer would be yes, if you don't then you life is going to be a lot harder at cracking email accounts.

It basically all depends on the security of the email.
