Yeah it’s possible to get influencer data at scale, but you need to be careful with how you do it. A lot of people try to scrape emails directly from Instagram or TikTok, but that can get accounts flagged really fast and it’s also a grey area legally. The safer way is to use influencer discovery platforms like Heepsy, HypeAuditor, Upfluence, Influence.co, etc. Those let you filter by niche, follower size, country, and many of them provide the public business emails too. It’s basically the same thing you want, just without breaking terms.
Another option is to work with micro-influencer communities or talent networks. They usually have thousands of small creators looking for deals and it’s easier to reach them since they already want partnerships. If you need it super fast, some agencies literally sell “done for you outreach” where they contact influencers on your behalf and you just talk to the ones who reply.
I’d avoid buying random email lists or scraping directly. The quality is usually bad and it’s a quick way to get your domain flagged as spam. If you want, tell me your niche and country and I can recommend which platform fits best and maybe how to approach the outreach part too.
