People ask which channel "works." LinkedIn feels native to a job search. Email feels more direct. Both get ignored for different reasons, and the useful question is which failure you can live with for this person.
How each one fails
LinkedIn fails in public, slowly. A note sits under a pile of other notes. Invites from strangers get a maybe-later. You can see they exist, and you can follow up in the same thread. You also spend the account's weekly patience every time you send.
Email fails in private, fast. It lands in a work inbox, which some people actually read, or it bounces, or it hits spam. You often will not know which. A wrong address is worse than no address.
Use LinkedIn when you are not sure of the inbox. Use email when you are sure of the person and the address.
A practical split
- Recruiter you can see on LinkedIn, no confirmed email. Start on LinkedIn. That is where they already talk to candidates.
- A peer with a verified work address. Email can be the cleaner ask. It does not depend on them accepting an invite first.
- Both, for two different people. One channel per person. Do not put the same pitch in someone's LinkedIn and inbox on the same day. That is a blast with extra steps.
- Neither, for your current employer. Block them before you choose a channel.
What not to do
Do not treat email as the unlimited version of LinkedIn. Mail providers notice volume and identical text too. And do not send email to a guessed address because LinkedIn felt slow. A bounce, or a note to the wrong Priya, is a worse outcome than waiting until the address checks out.
Pick the channel the person is most likely to read. Then write one specific note. Stop when they answer, on either channel.
