Every executive has fifty valuable relationships that have gone quiet. Most stay quiet because reopening them feels transactional, especially when you need something. It does not have to.
You are imagining that they will notice the gap and read the timing. In practice most people are pleased to hear from someone they liked working with, do not track the interval, and assume nothing about your motives unless the message tells them to.
What does read badly is a first message in years that consists entirely of a request. Not because asking is wrong, but because it says the relationship was storage.
A first message in three years that is only a request tells the other person what the relationship was for.
Sometimes something is happening now and there is no time to rebuild slowly. Say so: that you are conscious it has been a while, that something specific has come up, and that you would rather ask honestly than manufacture a reason to be in touch. Most people find that more respectful than the alternative, because it is.
Their view carries weight because it is first-hand. Seniority matters less than proximity to what you actually did.
Someone who changed company in the last year is inside a new organisation and usually pleased to be asked about it.
Reciprocity is real and long-lived. If you did something for someone, they have probably been waiting for a chance to return it.
Obvious, and the reason to have decided which companies those are before you start writing.
Some relationships have genuinely lapsed, and a warm message will not revive them. That is fine — the exercise is not to reanimate everyone, it is to find the ten that are still live and worth an hour each.
The ask that works is small, specific and easy to refuse. Most people make it large, vague and awkward to decline, and get silence.
