To export Instagram emails to CSV, you read the bio of every account on a list and write whatever address is there into a column. There is no API for it: the Graph API exposes no email field, and neither does Instagram's web payload. A browser extension that reads each bio inside your own signed-in session is the only route that returns the address as the creator wrote it, for a list of any size.
The Mastros Instagram Email Finder does exactly that. Choose a followers list, a following list, a post's commenters, an Explore page or a search result in the panel, run it, and the CSV or XLSX arrives with an email column beside every handle. It never guesses an address; a blank cell means the creator published none.
How do I export Instagram emails to a CSV?
Three steps: pick the list, run the export, open the file. The whole thing runs in Chrome on instagram.com, with no API keys, no password and no second login.
- Install the extension and open Instagram. Add the Mastros Instagram extension from the Chrome Web Store and open instagram.com in the same browser. It reads the session you are already signed into and asks for nothing else.
- Open the list you want to read. A competitor's profile for its followers, a post for its commenters, or a search result. Everything you can see on the page is exportable; nothing you cannot see is.
- Choose the surface in the Mastros panel and start. Followers, Following, Doesn't follow back, Comments, Search or Explore. Rows appear as the run goes. When Instagram limits the list, the run pauses instead of failing, keeps every row, and resumes after the cooldown.
- Save as CSV or XLSX. The file is named by surface, account and date. The email column holds each address exactly as written, with
(at),[at],ATand spaced@resolved to a normal address.
Best for: any list you can open. Every surface is free and unlimited during the launch beta.
Which list should I seed from?
The export is only as useful as the list you point it at. Three seeds cover most jobs.
A competitor's followers
Open a competitor or a peer brand, pick Followers, and export. The creators who follow a brand in your niche are, disproportionately, the ones who work with brands in your niche, and the ones with an address in their bio are the ones who want to. Sort the CSV by the engagement rate column before you read a single bio.
A post's commenters
Open a post that attracted the audience you want, whether yours or someone else's, and pick Comments. Each row is a commenter with their own bio email in its column, so a row is a lead rather than a handle. Likers export the same way, without the comment text.
A search or Explore result
Search Instagram for a niche term, or open Explore, and export the result page. This is the seed for "every account in this niche I have not heard of yet", and it is the one that turns a keyword into a contact list in a single run.
What happens when Instagram pauses the run?
Instagram limits how much of a list any account can read in one stretch, and a large followers list will hit that limit. The property to look for in any exporter is what it does next.
Mastros pauses, holds every row it has, and picks up where it stopped when the cooldown ends, usually a few hours later. Other surfaces keep working in the meantime, so a paused followers run does not block a comments export. Nothing is discarded and nothing has to be re-run from the top, which on a 50,000-row list is the difference between finishing and not.
What ends up in the CSV?
| Column | What it holds |
|---|---|
| username, full name | As shown on the profile |
| profile URL | Direct link |
| The address written in the bio, de-obfuscated, or blank | |
| website | The link in bio, resolved to its destination |
| followers, following, posts | Counts at export time |
| engagement rate | Over the last 12 posts, computed at no extra cost |
| verified, private, follows you | Flags as Instagram shows them |
Which method should I use?
| Method | Handles a list | Returns the bio address | Price | Where it runs |
|---|---|---|---|---|
| Read bios by hand | No | Yes | Free | Your browser |
| Graph API | No email field exists | No | Free, needs app review | Meta's API |
| Cloud scraper (Apify actor, SocLeads) | Yes | Yes, plus whatever else it collects | Usage-based or paid | Their servers |
| Mastros export | Yes | Yes, and nothing it did not find | Free in beta, then by record | Your browser |
The Graph API row is worth a second look: teams reach for it expecting an email export and find there is no field to export. It serves aggregate insights on accounts you own, not contact details on accounts you do not.
Who this is not for
- Anyone who wants an address for every row. Only creators who published one have one; the export tells you which, and a tool that fills every cell is inventing.
- Anyone who needs deliverability verified before sending. Mastros never sends an address anywhere to test it. An enrichment service does, and charges accordingly.
- Anyone building a mailing list from a followers export. Bio addresses are published for collaboration and booking, and bulk marketing to them breaches both anti-spam law and the reasonable expectation of the person who wrote it.
FAQ
Can I export Instagram emails without an API?
Yes, and there is no API that would do it anyway. The Graph API carries no email field. A browser extension reading the bio of each profile in your own session is the route, and the Mastros Instagram Email Finder is built for exactly that.
Does the export include phone numbers?
Only if a creator wrote one into the bio, in which case it is in the bio text column. Instagram does not put phone numbers in any list, and Mastros never looks anything up elsewhere.
How long does a large export take?
Longer than the row count suggests, because Instagram paces list reads and the run pauses when asked. A few thousand rows is a coffee break; a six-figure followers list is a day with pauses. The rows already collected are saved throughout.
Will my account get action-blocked?
Mastros adds no requests of its own for anything already on the page, paces every list it reads, and stops when Instagram signals a limit rather than pushing through it. It never follows, likes, comments or messages. That removes the usual causes rather than guaranteeing anything; Instagram's own limits still apply.
Can I export a private account's followers with their emails?
No. A private account's follower list is not visible to non-followers, so there is nothing to read. Any tool claiming otherwise is showing cached data or nothing.
