LinkedIn Outreach: Messages, InMail and Voice Notes That Get Replies
Short answer. LinkedIn outreach works when you treat it as a sequence, not a single message: a credible profile, a targeted list, a short personalised connection request, then messages that earn the conversation before any pitch. InMail reaches buyers outside your network and voice notes stand out inside it; generic requests sent at volume get ignored.

Why does LinkedIn outreach work for B2B?
LinkedIn outreach is prospecting through the platform's own channels: connection requests, messages, InMail and voice notes aimed at named buyers. It works for three reasons, and none of them is reach. The audience is professional and in a business frame of mind. The targeting is precise: filters for role, industry, company size and location find exactly the people who could buy. And the platform rewards credibility, because sharing useful posts keeps you visible between conversations.
None of that helps if the approach is random: generic requests fired at strangers produce silence and put your account at risk, which is why strategy matters more than volume here.
How do you prepare before sending anything?
Your profile is the first thing every prospect checks, and a poor one undoes a good message. Four fixes come first: a professional headshot, a headline that names the problem you solve rather than your job title, a summary written for buyers with a clear call to action, and a featured section showing case studies or your best content. If your profile only describes your career, it is working for recruiters, not your outreach.
Then build the list. Use LinkedIn Sales Navigator or the basic search, filter by title, industry and location, and favour second-degree connections, because a shared contact warms the approach. Build lists around moments rather than titles alone: events, industry news, launches that change what a prospect needs. A smaller list you can say something relevant to beats a large one you cannot.
How do you write connection requests and messages that get replies?
Personalise the request. Default templates are recognised instantly, and customisation visibly raises acceptance. Three reliable angles: mention a shared connection or genuine mutual interest, reference something they published or recent company news, and keep it under 300 characters. Do not pitch in the request; its only job is to be accepted by giving an honest reason to say yes.
The outreach starts, not ends, at the connection: a short thank-you with no pitch, then something of value relevant to them, then a question that invites their view, and only after trust is built, a soft pitch. Space messages three to five days apart, send midweek in the prospect's working morning or late afternoon, and stop when someone is clearly not interested. Between messages, stay visible: post useful content and comment meaningfully on your prospects' posts so your name is familiar before your ask arrives.
What are InMail credits and when does InMail beat a connection request?
InMail is LinkedIn's way to message members you are not connected to, and credits are its currency: one credit buys one message to a non-connection, no acceptance needed. Premium plans include a monthly allowance that varies by tier, free accounts can buy credits directly, and your balance sits under Settings & Privacy in the Account tab. Rules on unused credits have changed over time, so treat each month's allowance as that month's budget.
Use an InMail when the person is unlikely to accept a stranger's connection request, or when the first message needs more room than a connection note allows. Use a connection request when you share mutual connections or interests; the mistake is spending credits on people a free note would have reached. Write every InMail as a letter to one person: a short honest subject line, an opening that says how you found them, one clear reason to reply and one ask. LinkedIn's own reporting backs three habits: shorter InMails get more replies, individually written messages beat bulk sends, and InMails sent on Friday or Saturday get fewer responses.
How do you send a LinkedIn voice message?
Voice notes go only to first-degree connections, so the connection stage is part of the work. To send one: open the LinkedIn mobile app, go to the chat, tap the microphone icon in the message box, hold to record for up to one minute, preview and send. Recording is mobile-only, though recipients can listen anywhere.
Keep it under 50 seconds, structured as 10:30:10: ten seconds to introduce yourself, thirty on why you are relevant to this person and their company, ten on one concrete ask. Ask permission in a short text message first; a note that was agreed to gets listened to. If the note shows as listened for two or three days with no reply, send a short written follow-up, then move on. And choose the medium for the person: a non-native speaker may prefer a written message.
Should you automate LinkedIn outreach?
Cautiously, if at all. Tools such as Expandi, Zopto and Waalaxy can scale outreach, and misuse of them gets accounts restricted. If you use one, personalise the first message, test copy on small groups before scaling and respect daily limits. Whether you automate or not, measure like an email marketer: track connection acceptance rate, first-message response rate and qualified conversations started, and refine on data rather than assumption.
Why this works better on named accounts
The difference between social selling that works and spam is whether you knew who you wanted to reach before you logged in. On a named account, LinkedIn is one channel among several: the connection request makes you familiar, the content keeps you visible, a voice note or InMail carries the personal touch, and email or a call carries the specific ask. One accepted request also shows you the rest of the buying committee, and LinkedIn ads can keep the same named accounts warm while the messages do the asking. That is how LinkedIn outreach fits inside our approach to lead generation on named accounts.
Frequently asked questions
Should you pitch in a LinkedIn connection request?
No. The request's only job is to be accepted, so give an honest reason to connect: a shared contact, their content or relevant news. Pitching before the person has accepted marks the message as spam and lowers acceptance. The pitch comes later, after value and trust.
Can you send a voice message to someone who is not a connection?
No. LinkedIn restricts voice messages to first-degree connections to limit spam. The person must accept your connection request first, which is why a credible profile and a short, relevant connection note are part of the voice message play.
Do unused InMail credits carry over to the next month?
LinkedIn's rules on unused credits have changed over time and can differ by plan, so check the current terms of your subscription. The safe planning assumption is that each month's allowance is for that month, which encourages steady, deliberate outreach.
How long should a LinkedIn voice message be?
The recording limit is one minute, but aim for 50 seconds or less: around ten seconds of introduction, thirty seconds on why you are relevant to this person and ten seconds on a clear call to action. Rehearse it once before sending.
