Scrapevia

Scrapevia helps agencies, freelancers and sales teams find business leads on Instagram and send to emails that work. Enter a public Instagram profile, such as a supplier, a trade page or a competitor, and collect the accounts it follows. Filter them by followers and account type, look up the public email each business lists, and download a clean CSV. Then check the emails: each gets Passed, Failed or Unknown, so fewer messages bounce. One credit balance covers both tools, there is no subscription, credits never expire, and Unknown email results are never charged. New accounts get 100 free credits, and credit packs start at $5. Only information an account owner has made public is used, and private accounts are skipped. Scrapevia is not affiliated with Instagram or Meta.
