Linking to registration email URL after a signup form

So, today I was working on the 'thank you for... page' at the company that hired me. It is a page that is shown after the user 'requests' an offer for a certain treatment. Because of privacy rights we need to confirm that email before we can contact them.

While testing, I got an idea. We already know the domain of the email (for instance some populair: Outlook / gmail / hotmail / yahoo etc.). Why not make the email a link?

On the page we currently show the following text*:

Thank you for showing intrest in [product x]. We send an email to 'example@gmail.com' for verification. Please follow the instructions in the email.

*roughly translated.

My Question

Are there any negative UX related consequences for making example@gmail.com link to gmail.com?

I can only think of these 2, that do not seem to big:

• User miss typed their email. (Even this can be checked with some code. For instance if its @gmial.com dont make it linkable)
• The users adres used in the signup is not their primary email.

I've never seen this used in the websites i register for, so I'm curious if I'm missing something?

For instance, if you register on mobile and you link to gmail.com. Gmail.com will ask you to open the app.
