hello@mclookup.comResponse times
Expect an answer within one business day for most messages. If something is actively blocking your vetting workflow, flag it as urgent — those tickets are usually handled in under four hours during US working hours. There is no outsourced help desk here; the person replying is one of the engineers who built the site.
The Help Center covers how scores are computed, how lookups work, and the usual account questions — there’s a decent chance your answer is already written up.
