How often should we follow up with influencers if they do not respond?

Follow up once after about 3 to 5 days, optionally once more after a week, then stop. Beyond two follow-ups you are pestering, which hurts your reputation.

Keep each follow-up short, polite and additive rather than guilt-tripping and space them by days, not hours, so they read as persistent, not desperate.

Read the silence honestly: after two unanswered follow-ups it normally means not interested, wrong contact or bad timing, none of which a third message fixes.

The workable rhythm is one or two follow-ups, spaced a few days to a week apart and then you stop. Send your initial outreach and if there is no response after roughly 3 to 5 business days, a single polite follow-up is genuinely useful, because messages get buried, missed or deprioritized and a gentle nudge catches a lot of people who were interested but simply did not get to it. If that goes unanswered too, one further follow-up after about another week is reasonable. Beyond two follow-ups, though, you have crossed from persistent into pestering and continuing to chase someone who has ignored two messages damages your reputation more than it helps, since creators talk and nobody wants to work with a brand that will not take a hint.

What makes follow-ups land rather than annoy is how you do them, not just how often. Keep each follow-up short, polite and additive rather than guilt-tripping, a brief friendly bump that maybe adds a small new detail (a reason it is a good fit, a deadline) beats a passive-aggressive where are you. Space them sensibly (days, not hours) and never send rapid repeated messages, which reads as desperate. And read the silence honestly: after a couple of unanswered, well-crafted follow-ups, no response almost always means one of a few things, the creator is not interested, you reached the wrong contact (many creators route deals through a manager or a specific business email) or your offer or timing did not land and none of those is fixed by asking a third or fourth time. So the practical rule is follow up once after a few days, optionally once more after a week, keep each one brief and gracious and then move on, redirecting your energy to other creators rather than chasing a non-response. If a particular creator really matters, the better move than more follow-ups is to check you are using the right contact channel (manager, business email) and to make the offer more compelling, since persistence is not what converts a genuine no or a wrong-address into a yes.

This is an outreach-discipline question rather than a tool function, so there is no Flinque angle to force. The one adjacent, practical point: a chunk of non-responses come from reaching the wrong contact and starting from accurate, sourced creator contact details (which a discovery tool helps with) means more of your first messages land with the right person, so fewer of your follow-ups are chasing silence that was really a wrong address all along.
