Been there.
The problem is you’ve verified a single email address. I recommend you go to the “domain auth” in sendrgid and add the CNAME records, they provide you, to your domain DNS so that all the emails from the domain “trippledrinks” can be used and that error is no longer visible.
Checkout this post, it’s explained in detail.
(Helpful tip for authenticating Sendgrid *without* an admin email)
