pitching fashion creators through direct messages was wasting my entire workday.this scraper pulls public bio emails into clean sorted spreadsheets immediately.i never bother sending cold messages to unread instagram inboxes anymore.calculating engagement percentages before launching campaigns prevents massive advertising budget waste.

The email and contact-finding side of this extension is what stands out to me. Being able to pull creator details from Instagram and export them directly to CSV or Excel could save a lot of manual work. I also like that it shows the engagement rate and puts contact details near the front of the export instead of making you reorganize everything later. The resume feature is a nice touch too, especially when Instagram pauses a larger collection. Keeping the exports in the browser rather than uploading them somewhere is another reassuring detail.

This tool makes Instagram research much easier than doing everything manually. I like that it can pull useful profile details, engagement numbers, emails, and websites into a clean spreadsheet. The ability to resume an interrupted export is especially practical for larger lists. Having media downloads alongside the data is also convenient when collecting creator information for research.

I like that Mastros puts the useful contact details directly into the export instead of leaving me to collect them separately. Having email addresses websites and engagement data alongside the profile information makes the resulting spreadsheet much easier to work with. The resume feature is also helpful when Instagram pauses a longer run since I can continue without losing the rows already collected.

I tried Mastros on a public Instagram profile and the export worked well. It picked up the information from the profile, including the bio email, website, follower count, and engagement data, and the results were organized clearly in the exported file. It’s a useful tool for quickly collecting public profile information.

Finding someone's contact used to mean guessing addresses or sending DMs nobody answers, so on a tip I tried this for a hashtag search and got emails, follower counts and engagement rates right in the export. I only need it now and then, though the bio lookup saves so much time. Would pass it along.

Keeping a tab open and pasting rows by hand got old fast. A few weeks in, I check follower lists and comment exports most mornings now, emails and sites already at the front, sorted. Same on my desktop and laptop, no passwords, nothing installed in my account. It pauses on limits and picks up where it stopped. I'll keep it for reels and stories too.

Finding creator emails without waiting on ignored direct messages is huge blessing.It packs big follower lists into tidy spreadsheet with contact details placed right first.Checking true engagement score stops me from throwing budget at fake accounts.When page gets tired it pauses calmly and continues later without losing single name
