Contact-data coverage is how many creators a tool gives you a real, reachable email or contact for. Brands compare it by testing a sample: what share of a target niche has verified contacts, how current they are and how many bounce. Coverage means little if the contacts are stale or wrong.
How do brands compare influencer discovery tools specifically on how much contact data they cover?
Comparing tools on contact-data coverage matters because a great creator you cannot reach is not much use, though the headline coverage number can mislead. Brands test it rather than trust it. Take a representative sample of creators in your actual niche and check what share the tool provides a direct contact for, since coverage of celebrities you will never email is irrelevant to a micro-influencer campaign. Then test quality, not just quantity: how current the contacts are, whether they are the creator's own or a generic management inbox, then crucially the bounce rate when you actually send, because a big database of dead addresses is worse than a smaller accurate one. Weigh coverage against the rest too, since contact data is one dimension and audience accuracy and authenticity vetting often matter more to campaign outcomes. Flinque's strength is on that discovery and vetting side, the audience and authenticity data that decides who is worth contacting, which pairs with whatever outreach approach or contact source a brand uses to actually reach them.
