How to write an InMail that gets replies
- 1
Warm up the prospect first
Comment thoughtfully on 1–2 of their recent posts BEFORE sending the InMail. Familiar names get 2–3× the reply rate.
- 2
Reference the warm-up in line 1
'Saw your post on [topic] yesterday, your point about [X] caught my attention.' This is the single strongest opening.
- 3
Lead with value, not the ask
Share an insight, observation, or specific resource related to their situation BEFORE proposing anything.
- 4
Keep it under 100 characters
Long InMails get skimmed and discarded. Treat this like a Twitter DM, not a sales letter.
- 5
Make the next step zero-friction
End with a yes/no question or a single tap response, not 'happy to share more on a call.'
Frequently asked questions
What is a good LinkedIn InMail response rate?
10–18% is a typical InMail response rate for B2B cold sales outreach. Recruitment averages slightly higher (18–25%). Top-quartile InMails, usually warmed up via comment first and personalized in the opening line, achieve 30–45%. Generic 'I'd love to connect' messages average 3–7% and are effectively dead.
How many InMails should I send per day?
Quality beats quantity. 5–10 highly-personalized InMails per day produce more booked calls than 50 generic ones. LinkedIn rewards higher reply rates with better deliverability over time, so consistent personalization compounds, generic blast outreach gets soft-throttled within weeks.
Are InMails better than connection requests?
Depends on intent. For first-time outreach with a clear value prop, InMail outperforms (you skip the accept/reject step). For relationship building, connection requests are better, they cost no credit, allow a personal note, and a connected user is worth more long-term than an InMail recipient.
What time of day should I send InMails?
Tuesday through Thursday, 8–10am in the recipient's local timezone. Response rates drop 30–50% on Mondays (people clearing inbox), Fridays after 2pm, and weekends. Avoid sending late at night, the InMail won't appear at the top of the inbox by morning.
How do I avoid getting flagged as spam by LinkedIn?
Three rules: (1) personalize every InMail with at least one specific reference to the recipient (post, role, company milestone), (2) keep response rates above 10%, chronic low-response senders get throttled, (3) avoid links in the first message; they trigger LinkedIn's spam pattern detection.
