The form on left is almost certainly a webform-to-email, this is ridiculous.
looking at font choice, how ironic they are complaining about UX
If you put an email address on a contact page, all manner of sh*t is going to be thrown at you.
Automated marketing services, scammers, competitors, everyone and their dog are going to be filling up your customer service inbox and costing you time and money to manage it.
Put a contact form on your website and you can secure it with a capture, which is not bulltproof but it sure does filter out a lot of automated noise for you. Then you will find that people are generally a lot quicker to fire off an email than fill out a contact form. In my experience this generally puts one more 'thinking barrier' between you and the public, which again cuts down noise significantly.
Also, click the 'settings' button in the bottom right, and you will see they have given you a choice of fonts. Sometimes it pays to look a tiny bit further to see whether your issue has already been solved, before complaining about it.
And if any of your customers or business partners know of the company e-mail, then you're already known to all spammers in the world, since their contact lists are getting hacked all the time.
Ie: If you're a business your e-mail adress is already out there, so give it also to those who need it the most, which are your customers.
