Most cold messages fail for the same reasons
They open with a pitch, they're about “us” not “you”, they're stuffed with salesy words, and they never ask a simple question. So they get skimmed, deleted, or flagged as spam, and your account's reputation takes the hit.
Lead with something genuinely useful, keep it short and personal, ask one easy question, and replies follow. Neuron Outreach writes messages like that for you, and finds the people worth sending them to.
Good to know.
Whether your message leads with value instead of a pitch, how many spam-trigger words it has, its length, whether it's personal, whether it asks a question, and reputation red flags like links or “DM me”.
Usually because it opens with a pitch, includes salesy/spam words, or has no question for the reader to reply to. The suggestions tell you exactly what to change.

Cold email usually gets 1–5%; warm, personalised DMs 10–20%. Value-first messages sit at the top of those ranges, try our reply rate calculator too.
