Oh, the scraping route - a lovely way to get your account nuked and your sender reputation shredded in one fell swoop. Instagram's detection is getting tighter by the week, so those workflows are about as reliable as a free webinar from a LinkedIn guru. account bans on the scraping side, deliverability hell on the receiving side - proper double jeopardy.
the legit play? Partner with the actual accounts. paid creator collaborations, guest appearances in their content - you hit the same audience, but with permission and actual engagement. Cold scraping converts about as well as a pop-up ad from 2005. if you really need contact info, supplement with public records matched to Instagram bios. decent enrichment tools do this without breaking platform rules.
That scraping shortcut isn't a shortcut. it's a slower, riskier route dressed up in bad marketing jargon. Don't be that person.
