It's a mistake to equate recruitment emails with ability to get a job. There are many reasons for recruiters to send you emails that have very little to do with your likelihood of being hired. Talented engineers will always be difficult to find, though the challenge may change from trying to find one that's not employed to finding the best among those that need a job. Recruiters are just casting a wide net for a few seats. Some independent recruiters, given the payout involved, cast that net very wide (and generally contribute to low quality candidates stuffing up your hiring manager's inbox). Had you said you recently got a lot of offers, that would be a totally different story.
