Verification emails from user accounts form doesn't work properly

Hi I’m asking for your help in regards of emails sent by webflow form registration within the user access function.
When an account on my web is created, the verification email gets send, the problem i noticed is occurs on some email services, google mail service works, but for example email.cz does not. About the problem - links in the message are non-clickable, the button, the link under both doesn’t work, the link can be copied and pasted into the browser, but i’d like to avoid this hassle for the users. I reckon there might be a problem with the generated messages code HTML.
