When I was looking for a new job around 8 months ago I worked with an agency recruiter - the type that shops your resume around, not an in-house recruiter - to get some interviews. Working with them went fairly well and I wound up with a decent offer, but somewhat unexpectedly also got a "dream job" type offer from a company I had applied to directly, and accepted that instead. The recruiter seemed disappointed but understanding, and even sent a follow-up email a few months later, so I think that bridge was not burned.
Now my spouse is on the job market. I think this recruiter would probably have some relevant postings or contacts, so I want to put them in touch via email. I don't know who is expected to do the reaching out though.
My concerns are that if my spouse emails, maybe the recruiter would skip over it since he's not in their address book.. if I do it, maybe it will look like he's not taking initiative. On top of that, I've also managed to offend a (different) recruiter in the past by what I thought was a polite email, so while this probably sounds like overthinking - I'd like to be sure I'm following best practices.
What is the professional etiquette for connecting someone with a recruiter you've worked with before?
(In case it's relevant, this is in the northeast US, tech industry.)
