A rejection email is data, not a verdict. Read it, adjust, send the next one.

Rejection reads as a judgment because it arrives addressed to you, but it is mostly a report on the fit between a document and a need at one moment. The decision was made in a few minutes by someone comparing several people. Treating it as a statement about your worth gives a routine piece of information a role it cannot support.

Read it once for anything specific, then send the next application that same week. Volume is the part most people underestimate. If several come back with the same note, act on that, since one on its own rarely means much.
