Instagram · Chrome extensionInstagram Email Finder
Mastros's Instagram email finder collects the business email and website that creators publish in their own bios, as columns on followers, following, search and explore lists, and saves them as CSV, XLSX or JSON. The Mastros Instagram extension reads the bio your browser has already loaded, pulls any address written there, and writes it beside the profile in a CSV or XLSX file. Instagram's web interface exposes no contact-email field at all, so a bio is the only place a public email exists. Mastros never guesses an address, never buys one from a data provider, and leaves the column blank when a creator published none. It does not recover the email on an account you are locked out of and cannot help with a locked account; for that, use Instagram's own account recovery.
Bio addresses only · No credits · Nothing guessed · Runs in your browser
MastrosIf you want the full follower or following list rather than the emails, use the Instagram follower export tool; for a post's comments, Instagram comment export.
The one thing to know first
Instagram publishes no contact email, only bios do
Instagram's web interface returns no email field of any kind. Mastros checked this across five capture runs on profiles that did return the business address, city and category fields, so the contact block is deliberately absent rather than merely empty. Meta's own Graph API tells the same story: its business_discovery endpoint exposes no email either. The business contact button lives in the phone app and nowhere else.
So there is exactly one place a public Instagram email exists: the bio the creator typed. Mastros reads that, resolves the anti-bot obfuscations creators use, and writes what it found. When a creator published nothing, the cell is empty. That gap is the product working, not failing.
What Mastros does
- Reads the biography text already loaded in your browser and pulls every address written in it.
- Resolves name (at) domain, name [at] domain, name AT domain and spaced-@ forms into normal addresses.
- Writes them beside the handle, follower count, profile URL and engagement rate in one row.
- Leaves the cell blank when the bio has no address in it.
What Mastros does not do
- Return the business contact email. It is not on the web, and any tool that hands you a full column of them is not reading Instagram.
- Guess an address from a name and a company domain.
- Buy, look up or verify an address through any outside provider.
- Send a single exported row to a Mastros server. The file is built in your browser.
Where you get it
Every Instagram export that carries an email column
The email is not a separate tool or a separate run. It is a column on the exports the Mastros Instagram extension already offers, so finding addresses across a followers list and exporting that list are the same action.
Profile
One creator as a single row: bio, followers, following, posts, external link, engagement rate, and every address found in the bio.
Followers and Following
Everyone following an account, or everyone it follows, with an email column filled per profile from that profile's bio.
Doesn't follow back
Following minus followers, computed from two exports you already ran. Carries the same email column.
Comments and likers
The people under a post, with the commenter's own bio email in its own column so a row is a lead rather than a handle.
The email column is one capability of the Mastros Instagram extension, which covers followers, posts, reels, stories, comments and media from a single install. How it compares with the other finders is in Best Instagram email finder tools.
How it works
How to find an Instagram creator's email address
Five steps, from an empty browser to a spreadsheet with an email column.
Add the Mastros Instagram extension
Install it from the Chrome Web Store. It needs no Instagram password and reads no cookies. You stay signed in normally in your own browser.
Open the profile or list you want
A creator's profile, or the followers or following list of an account you can already open. Mastros reads what your own session displays and cannot reach a private account you do not follow.
Open the Mastros panel and pick the export
Choose Profile for one creator, or Followers, Following or Doesn't-follow-back for a list. Every one of these carries an email column.
Mastros reads the bio text
For each profile it scans the biography for an address, including the obfuscated forms creators use to dodge bots: name (at) domain, name [at] domain and name AT domain all resolve to a normal address.
Save the file
The email lands in its own column next to the handle, follower count and profile URL. CSV and XLSX open directly in Excel and Google Sheets.
How to find an Instagram email by username
Open the profile on instagram.com and run the Profile export from the Mastros panel. It reads the bio text your browser has already loaded and writes any address it finds beside the username. If the bio has no email, there is none to find on the web, and the cell stays blank.
Free Instagram email finder vs paid tools
Every tier exports followers and following, Free included; a row cap applies once the beta ends, and nothing is purchasable today. Modash-type databases charge a subscription for discovery across millions of accounts, which is a different job: they find creators you have not heard of, while the extension reads the profiles you already have in front of you. Neither replaces the other.
Modash and other influencer databases
A database is the better buy when the job is discovery: finding creators in a niche you do not know yet, filtering millions of accounts by audience size, location and category, and getting a contact for each one in one place. It costs a subscription, and it returns addresses from its own sources rather than only from the bio. If you already know which profiles you want, the extension gets their published emails for less, from your own browser.
Honest comparison
A bio reader and an enrichment tool are not the same product
An enrichment tool will return more addresses than Mastros, and it should. That is what its database and its credits are for. What it cannot tell you is which of those addresses the person actually published. Mastros answers only that narrower question, and answers it with the creator's own words.
| What matters | Mastros | Email-enrichment tools |
|---|---|---|
| Where the address comes from | The creator's own bio text, read from the page you have open | A third-party database, or a guess from name and domain |
| Addresses the creator never published | Never returned. The column is blank instead | Usually returned, which is the point of the product |
| Cost per address | Nothing. Rows are counted, not addresses | One credit per lookup, verified or not |
| Obfuscated bios (name (at) domain) | Resolved. Four obfuscation patterns are handled | Varies by vendor |
| Where the profile data is processed | In your browser. No row reaches a Mastros server | Sent to the vendor, which is how the lookup works |
| Coverage | Only creators who wrote an address in their bio | Higher, at the cost of accuracy and provenance |

I tested the extension and everything I tried worked smoothly chat messages exported successfully to csv, group members were well organized, and media was downloaded into a zip file i especially liked that it can find a member’s profile name when it isn’t shown in the group.
Works really well and saves me a lot of time when downloading Telegram videos and media. Simple, useful, and easy to use.
Building lead lists used to feel like an endless punishment of copy pasting profile URLs all afternoon.This extension detects search results instantly and pulls the whole batch into an excel file with clean aligned columns
