Built a small utility Actor and I would like blunt feedback from people who sell here, not from users. Email Verifier & Phone Number Validator: takes a pasted list or, more usefully, the dataset of another Actor's run, and returns per-row verdicts. Emails get syntax, live MX lookup, disposable and role-address flags, and typo correction (gmial to gmail). Phones get numbering plan, line type, US state and time zone. Nothing is sent, so nothing burns a domain. The reason it exists: a lot of contact Actors on the Store output rows nobody checked, and the buyer finds out at send time. Chaining a verifier after a scraper fixes that in one run. Two things I would like tested, and I will owe you one: does the dataset-input mode actually work against your Actor's output, and is it obvious from the Store page who this is for? apify.com/lergassy/email-phone-verifier

for me at least, "utilities" is the worst selling actor category... but your input/output formats looks easy enough to pipeline with other actors.
