The average response rate to recruiter InMail is 18-25%. That means 75-82% of your messages are being ignored. For top candidates in competitive fields like engineering, it's even worse — under 10%.
What Candidates See When You Message Them
A senior engineer at a top company gets 5-15 recruiter messages per week. They've developed a two-second filter: if the first sentence sounds like a template, they delete without reading.
These phrases trigger the filter instantly: "I came across your profile and was impressed by your background." "I have an exciting opportunity I'd love to discuss." "Are you open to new opportunities?"
What Gets Responses
Specificity. Reference something only THEIR profile has. Not their company name (too easy) — their specific project, a talk they gave, an article they wrote, or a specific skill combination that's rare.
Brevity. Your message should be 3-5 sentences. Not a job description. Not a company overview. Just enough to earn a reply.
A soft ask. "Would you be open to a 15-minute call?" is better than "I'd love to set up an interview." Even better: "Is this the kind of thing you'd want to hear more about, or should I leave you alone?" Giving them an easy out paradoxically increases response rates.
The Research-to-Message Ratio
The best recruiters spend 5 minutes researching and 2 minutes writing. Most recruiters spend 0 minutes researching and 5 minutes writing. Flip the ratio. The research IS the message — when you reference something specific, the candidate knows you did your homework.
Scaling Personalization
The challenge: you can't spend 7 minutes per message when you need to reach 50 candidates. This is where AI tools like HireFlow help — they read the profile data and draft a personalized message that you review and tweak in 30 seconds instead of writing from scratch.
The key: AI generates the draft, you add the human touch. Never send an AI-written message without reading it. Candidates can tell, and it backfires.
Follow-Up Matters
40% of responses come from the second or third message. If you're not following up, you're leaving almost half your pipeline on the table. Space follow-ups 5-7 days apart. Change the angle each time — don't just "bump" the original message.
