Why it matters
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.
What it checks
- Leads with valueStarting with something useful beats starting with a pitch.
- Spam words and red flagsSalesy phrases, links and shouting can land you in the spam folder.
- The right lengthAbout 40 to 130 words is long enough to land and short enough to read.
- Personal, with a questionTalks to them, and ends with one easy question to answer.

Good to know
Questions, answered plainly.
What does it check?
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”.
Why did my message score low?
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.
Is it free and private?
Yes, no login, and your message is scored in your browser. Nothing is sent or stored.
What's a good reply rate?
Cold email usually gets 1 to 5%; warm, personalised DMs 10 to 20%. Value-first messages sit at the top of those ranges, try our reply rate calculator too.
