How to build relationships with influencers when you want to promote your product?

This is more of a feedback for marketers who are trying to establish contact with bigger influencers.

Thanks to my experience from "both sides", I noticed certain patterns that could work better and satisfaction would be on both sides. :)

Here are my points for better collaboration with influencers:

1️⃣ When reaching out, mention it’s a paid collaboration. If you don’t have a proposal, ask for their price list—big influencers filter messages that don’t clarify this. They don't have time to deal with every message.

2️⃣ Instruct them. Make a custom tutorial on how the product works, not every person fell from the sky as a scholar; that's why they need instructions, ideally a video tutorial.

3️⃣ Offer an extended trial or free version to motivate long-term use and organic promotion – but only if the influencer finds it relevant to their workflow.

4️⃣ Establish conditions beforehand and organise everything in advance. If you do things haphazardly and at the last minute, the output will also be poor. In short, don't expect a miracle.

5️⃣ Track. You're a marketer, so there's probably no need to say much about this. 😀

What point would you add that has worked for you?
