On the targeting question, the practical split is usually audience fit versus reach volume: a smaller list of outlets that actually cover your niche tends to beat a large generic wire blast, though the general wire still has value for regulatory or corporate announcements that need a public record. When judging a financial PR service, I'd look at whether it publishes a real, checkable list of recipient outlets, how it handles compliance-sensitive wording, timing around market hours, and whether it reports actual pickup rather than just delivery counts. For forex and fintech, sector familiarity matters mainly because the wording has to survive scrutiny from journalists who know the space.
