X is where founders, marketers, and niche communities say who they are in 160 characters and a link. Outsoci searches by keyword or handle, mines bios and pinned links, and turns the accounts that match your niche into a verified, exportable lead list. Engagement-based targeting adds an intent layer few other platforms can match.
Describe who you want — job title, niche, business type — plus an optional location.
Outsoci searches live and pulls matching profiles and their public contact details.
Emails are verified and deduplicated, then exported to a clean CSV in one click.
Handle & display name
a stable identifier and the first personalization detail
Bio text
role, company, and often a plain or obfuscated email
Follower count
a rough proxy for reach and audience size
Location (if set)
useful for territory filtering when users opt to show one
Linked website
the profile link, unshortened past t.co, and crawled for contact info
from the bio directly or the linked site's contact page, then verified

Volume ceiling. Around 1,500 profiles per keyword or engagement-target run before pacing kicks in. Expect the widest email-match variance of any platform here — 30–50% for indie builders and freelancers, under 15% for large brand accounts.
X's bio field is compact but high-signal — indie founders, freelancers, and niche professionals routinely put a contact email or a personal-site link right there because it's the fastest way to be reachable in a platform with no formal contact directory. Outsoci scans bios for both plain and lightly obfuscated addresses.
Beyond the bio, X shortens every outbound link through t.co. Outsoci resolves those redirects to the real destination — usually a personal site, a newsletter, or a company page — and crawls it the same way it would a Google Maps listing's website, looking for a contact or about page with an email.
X also supports a genuinely different targeting angle: engagement. Instead of searching by keyword alone, you can target people who reply to, quote, or engage with a specific account — a competitor's launch thread, an industry hashtag — which surfaces an audience that's already self-selected as interested in your topic.
Expect X to have the widest variance in email-match rate of any platform Outsoci covers: prolific indie builders and niche creators often list an email outright, while larger accounts, brands, and casual users rarely do. That variance is itself useful information — a bio-listed email is frequently a stronger approachability signal than a locked-down corporate account with a generic support link.
People who engage with a competitor's posts are pre-qualified as interested in the category — a warm, intent-driven segment.
Finding the accounts already talking about your product category, framework, or niche before you launch an outreach push.
Sourcing quotable, engaged voices in a niche for a story, survey, or market research project.
Identifying accounts active in a specific niche (indie hackers, a tech stack community) ahead of a product launch.
Following the accounts most active in a niche (fintech, climate, developer tools) to spot emerging builders early.
Does X show email addresses on profiles?
Not as a dedicated field, but many users put one directly in their bio text, and profile links frequently lead to a site with a contact email.
Is this the same as using the X API?
No. The official X API has restrictive pricing and limits for this kind of bulk profile search. Outsoci works from public profile pages instead, which keeps it accessible and affordable.
Can I target people who engage with a specific account?
Yes — targeting repliers, quote-tweeters, or engagers on a given post or account is one of the strongest intent signals on X, since it means they're already paying attention to that topic.
What happens to t.co shortened links?
Outsoci resolves every t.co link to its real destination before crawling it, so you get the actual site behind the shortener, not a dead-end redirect.
Is scraping public X profiles legal?
Scraping publicly visible profile data sits on firmer legal ground than automating a logged-in account. Your outreach still has to comply with GDPR, CAN-SPAM, and similar rules.
How fresh is the follower and bio data?
Searches run live at request time, so bios, follower counts, and links reflect the current state of the profile rather than a cached snapshot.
Does this work for both personal and company accounts?
Yes — company accounts often link to a support or press page, while personal and creator accounts are more likely to list a direct email or a personal project link.
Can I export the list directly to a cold-email tool?
Yes — exports use standard CSV columns (handle, name, bio, email, follower count) that import into Instantly, Smartlead, or any CRM that accepts CSV.
Can I combine keyword search with engagement targeting?
Yes — narrowing by niche keyword first, then targeting engagers on a specific post within that niche, produces the tightest, most intent-qualified segment.
How is this different from buying a follower list?
A bought follower list is a static snapshot that ages immediately. Outsoci searches live, so bios, links, and follower counts reflect the account's current state.
