Yesterday I sent a message about my work to my boss. The message was this:

"this is the design I designed yesterday"

After I sent the message, I started to think maybe I should have added the word "that"

"this is the design that I designed yesterday"

Which one of these are correct, and what does changing it imply?

It's grammatically correct either way and means exactly the same thing with or without it. Leaving it out, as you did, would be the most common form.

[Incidentally: the "design I designed" construction is valid but reads a little awkwardly. I'd go for "this is what I designed yesterday"]

    As Richard says, one doesn't design designs. One prepares/produces/creates (and lots of other possibilities) them. Apr 12, 2022 at 9:32
