How to build a micro-influencer contact list

Why 1K–100K creators convert best for outreach, and how to find them at scale.

The short answer

A micro-influencer contact list targets creators roughly in the 10K–100K follower range (and nano creators from 1K). They matter because published creator-economy benchmarks consistently show engagement and reply rates falling as follower count rises, so smaller creators tend to be both cheaper to work with and more likely to answer. Build the list by searching a niche's hashtags and keywords with a follower-range filter, then verifying every contact before outreach.

A micro-influencer list is a deliberate bet: trade the reach of a few big names for the engagement and reachability of many smaller ones. Here's why that bet usually pays, and how to assemble the list.

Why smaller creators win on outreach

Across publicly published creator-economy benchmarks, the pattern is consistent: engagement rate and reply rate tend to fall as follower count rises. A nano creator often has a tighter, more responsive audience than a macro account, and — just as important for outreach — they usually still read their own DMs and email rather than routing everything through a manager.

Follower band	Typical profile	Outreach fit
Nano (1K–10K)	Highest engagement, self-managed	Best reply rates; volume plays
Micro (10K–100K)	Strong engagement, business email in bio	The sweet spot for most campaigns
Mid (100K–500K)	Manager-gated, rising rates	Reach plays; expect a gatekeeper

How to source the list

Start from the niche, not the individual. Pick the hashtags and keywords that define the sub-vertical you want, apply a follower-range filter to stay in the nano/micro band, and pull the profiles that match. On TikTok you can also scrape the commenters on a viral post in the niche — a pre-engaged pool. From there, snowball: the followers and following of one good creator map the rest of the niche.

Filter to a follower range (e.g. 1K–100K) so you don't waste budget on unreachable macro accounts
Target sub-verticals one at a time rather than a broad tag
Recover and verify each email before it enters the list
Add a line-typed mobile where you need a second channel

Verify before you send

A micro list is only worth building if it's contactable. Data age is the single biggest driver of email bounces, so verify addresses close to send time rather than trusting a snapshot. Trackyr SMTP-checks each email when you verify and can line-type a reverse-appended mobile, so the list you export is one you can actually work.

// Common questions

Answered.

What counts as a micro-influencer?+

Definitions vary, but micro is commonly the 10K–100K follower band, with nano below that (roughly 1K–10K). The exact cutoff matters less than the pattern: smaller, more engaged audiences.

Why do micro-influencers convert better for outreach?+

Published creator-economy benchmarks generally show engagement and reply rates declining as follower counts climb. Smaller creators also tend to manage their own inbox rather than route through an agency, so they're more reachable.

How many creators should a micro-influencer list have?+

Because reply rates are a fraction of sends, most operators build lists in the hundreds to low thousands per campaign, weighted toward nano/micro, and verify the whole list right before sending.
