How to Find Creators and Influencers by Niche (and Reach Them)

Prospecting for creators breaks every habit you built prospecting for companies. There is no domain to crawl, no team page, no imprint, and frequently no website at all. The profile is the business, and the contact details are wherever the creator decided to put them — usually a line in a bio, sometimes a link tree, occasionally nowhere.

This is how to build a creator list that is actually workable, whether you are running influencer campaigns, selling a service to creators, or recruiting affiliates.

First decide which of the three jobs you are doing#

They look identical and they need different lists.

Hiring creators for a campaign. You care about audience overlap with your customer, engagement rate and posting consistency. Follower count is the least useful number on the page.

Selling something to creators — editing, management, merch fulfilment, accounting, a course. You care about signals that they are running this as a business: a media kit, a business email, a shop link, sponsored posts already in the feed.

Recruiting affiliates. You care about whether their audience buys, which shows up as affiliate links already present in the bio and product recommendations in the content.

The list-building mechanics are shared. The filters are not, and running the wrong filter is why so many outreach campaigns to creators get zero replies: a hobbyist with 40,000 followers has no reason to answer a business proposal, and a professional with 6,000 has every reason.

Finding them: five methods, roughly in order of yield#

1. Hashtag and keyword search inside the platform#

The obvious one, and still the best starting point on Instagram and TikTok. Search the niche hashtag, sort by recent rather than top, and note who posts consistently rather than who has one viral video.

Go narrower than feels natural. #fitness is a firehose of reposts. #kettlebellcoach, #homegymuk, #postnatalfitness return actual practitioners. The narrower tag is also where the accounts with 5,000 engaged followers live, and those convert better than the ones with 500,000 passive ones.

2. The "similar accounts" graph#

Open one perfect-fit creator and follow the platform's own suggestions. On Instagram that is the suggested-accounts row after you follow someone; on YouTube it is the channels sidebar; on TikTok it is the "suggested accounts" panel.

This is the highest-precision method that exists, because the recommendation is built from real audience overlap rather than from a word in a caption. Two or three hops out from a known-good account and you have a niche map no keyword search would have assembled.

3. Comment sections of the biggest account in the niche#

The top account in any niche has smaller creators in its comments — that is how they grow. Those smaller accounts are the ones with time to reply to you.

4. Brand collaborations already happening#

Search the mention tag of a brand that sells to the same audience as you. Every creator who has already done a paid post for a comparable brand has: a rate card, an invoicing process, and a demonstrated willingness to work with sponsors. They are the shortest path from first contact to a booked campaign.

5. Aggregate the platforms rather than picking one#

Most working creators exist on two or three platforms and publish different contact details on each. It is entirely normal for a TikTok bio to say "IG for business enquiries" and the Instagram bio to carry the address. Collecting across Instagram, TikTok and YouTube and merging by handle gets you an address for accounts that looked uncontactable on any single platform.

Reading the numbers so you do not waste the outreach#

Four checks, none of which need a paid analytics subscription.

Engagement rate, computed by hand. Take the last nine posts, average likes plus comments, divide by follower count. Rough working bands for small and mid creators: under 1% is a dead or bought audience, 1–3% is normal, above 3% is genuinely engaged. Larger accounts run lower — a 500,000-follower account at 1.5% is healthy.

Comment quality, not comment count. Twenty comments saying "🔥🔥" are an engagement pod. Five comments asking "what size did you get?" are a buying audience.

Posting consistency. Look at the gaps between the last ten posts. A creator who posted daily for six months and then stopped four months ago is not going to reply to a partnership email.

Follower growth shape. A profile with a flat history and one vertical jump bought followers. You do not need a tool to see this: a 90,000-follower account whose posts get 80 likes tells you the same story.

Where the contact details actually live#

In descending order of how often they work:

Location	Notes
Bio line, written as name (at) domain (dot) com	Deliberately obfuscated to dodge scrapers. Reads fine to a human, needs normalising before you send
Instagram "Email" contact button	Only present on business and creator accounts; not visible in every context
Link-in-bio page	Link trees frequently hold a "business enquiries" address the profile itself does not show
YouTube channel "About"	Historically the most reliable creator contact surface anywhere
Personal website or Substack	Once a creator has a domain, the usual crawl works
Management agency address	Above roughly 100,000 followers this replaces the personal one
Nowhere	A real outcome. The DM is then the only route

Two practical notes. First, obfuscated addresses need cleaning before they are usable, and a naive collector will hand you namedomaincom or drop the row entirely — clean and then verify, the same as any other list. Second, when the only visible contact is a management agency, that is the right contact. Writing to the creator's personal address behind their agency's back is how you get blocked by both.

The DM versus the email question#

For creators, unusually, the DM is often the better channel — but only under conditions.

DMs win when the account is small enough that the creator reads their own messages, when the request is short, and when what you are proposing is interesting rather than transactional. They lose completely once an account has a management layer, and they are unsearchable later, which makes them poor for anything with a paper trail.

Email wins for anything involving money, contracts, deliverables or a deadline. If your first message would need a follow-up with an attachment, start on email.

The mistake is treating a DM as a shortcut around a badly targeted list. A generic DM to 200 creators gets you reported, and Instagram's response to that is a restriction on your account.

What to actually say#

Creator inboxes are full of two things: obvious mass mail, and "collaboration" offers that turn out to mean free product in exchange for work. You are competing against a very low bar, which is good news, and against a very high suspicion level, which is not.

What earns a reply:

• Name a specific post and say something true about it. Not "love your content" — the fifth message today opens that way.
• Say what you are offering in the first two lines, including whether it is paid. "Paid, £X per post" in the opening beats a paragraph of positioning.
• Say why them and not somebody else. Audience fit, in one sentence.
• Ask one question with a one-word answer. "Do you take paid partnerships at the moment?" outperforms "let me know your thoughts".

What kills it: attachments in the first message, a calendar link before any conversation, and the word "collab" carrying the weight of an unstated budget of zero.

The general principles are the same ones in cold email templates that get replies — the difference is that creators can look you up in ten seconds, so a profile and a website that look real are doing half of the work before your message is read.

Sending to a creator list without burning your domain#

Creator lists have two properties that make them harder on deliverability than a normal B2B list:

• A high share of free-mail addresses. Gmail, Outlook and iCloud make up much more of a creator list than a company list, and consumer providers are stricter about unfamiliar senders.
• A high obfuscation rate, which means transcription errors, which means bounces.

Both push the same way: verify before you send, keep daily volume low, and warm the domain properly. All of that is in the deliverability guide, and it matters more here than on a list of clinics and law firms.

One more thing specific to this audience: creators talk to each other. A campaign that annoys forty of them in one niche gets screenshotted. That is not a legal risk, it is a reputational one, and it is far more expensive.

FAQ#

How do I find an influencer's email address?#

Check the profile bio first, then the contact button on business and creator accounts, then the link-in-bio page, then the channel About tab on YouTube, then any personal website. Above roughly 100,000 followers, expect a management agency address instead of a personal one. Addresses written as "name (at) domain" need normalising before use.

What engagement rate is good for a small creator?#

For accounts under about 50,000 followers, 1–3% is normal and above 3% is strong. Below 1% usually means a bought or lapsed audience. Larger accounts run lower rates naturally, so compare within a size band rather than across all of them.

Is it legal to email creators I found on Instagram?#

An address published publicly for business enquiries can be used for a relevant business approach in most jurisdictions, subject to the same rules as any cold email: identify yourself, make the purpose clear, honour opt-outs. Be more careful than with a company list, because many creators are individuals rather than registered businesses, and several jurisdictions apply stricter consumer rules to individuals. The wider picture is in is scraping Google Maps legal, which covers the same distinction.

Should I use a paid influencer database instead?#

They are useful for large campaigns in mainstream niches, where the filtering saves real time. They are weak precisely where the money is — small niche creators, non-English markets, and anyone who grew in the last few months — because the database is a crawl someone else ran a while ago. Building your own list from the live platforms covers the long tail those tools miss.

Do creators reply better to DMs or email?#

DMs for small accounts and short, interesting propositions. Email for anything involving budget, contracts or deadlines, and always once an account has management. Do not use DMs as a workaround for a poorly targeted list — mass DMs get accounts restricted.
