Not bothering me in the first place, or maybe taking a hint.
If I didn’t reply to your first or second emails, assume I don’t want to. A motivating example: the only people who have ever emailed me repeatedly and used language like, “one last time” are cold calling salespeople and recruiters. I do nothing when they initially reach out, but when they start using tactics like this I send them directly to spam. I get that they have to sing for their supper, but I won’t respond to synthetic overtures of familiarity or urgency.
