Do LinkedIn voice notes work for outreach?
By Tirth Shah, founder of Bub · Updated
Yes, when they're used at the right moment. A short, personal voice note stands out in a LinkedIn inbox full of text because it's obviously from a real person. It works best as a follow-up or a reply to someone who's already engaged, kept to 20 to 40 seconds, and it works worst as a cold opener to a stranger. LinkedIn only lets you record voice notes in its phone app; Bub, a free Chrome extension, lets you record and send them from your laptop.
Add Bub to Chrome, it's freeWhy voice notes get noticed
- They break the pattern. Most LinkedIn messages are text, and many read like templates. A voice bubble looks different before it's even played.
- They prove you're human. Your voice, their name, a specific detail: nobody mistakes that for a mass sequence.
- They carry tone. Warmth and humour that take three paragraphs to write come through in ten seconds.
When voice notes work, and when they backfire
| Situation | Voice note? | Why |
|---|---|---|
| Following up after no reply | Yes | A different format gets a second look |
| Thanking someone for accepting | Yes | Personal, low pressure |
| Answering a question they asked | Yes | Faster for you, clearer for them |
| Re-engaging an old conversation | Yes | Stands out among new messages |
| First message to a total stranger | Usually not | Can feel presumptuous; start with text |
| Anything you'd send to 500 people | No | Generic voice notes are worse than generic text |
LinkedIn only allows voice messages to your 1st-degree connections and in group chats, so voice naturally fits after someone has accepted your invitation.
How to make a voice note that gets a reply
- Keep it 20 to 40 seconds. LinkedIn's limit is one minute.
- Say their name in the first few seconds.
- Mention one specific thing: their post, a new role, a mutual connection.
- Make one point, then ask one easy question.
- Don't read a script. Three bullet points and a natural tone beat a perfect take.
- Add one line of text so they know what it's about before they press play.

The easiest way to send LinkedIn voice notes
| Tool | Where you record | Cost |
|---|---|---|
| LinkedIn phone app | On your phone | Free |
| Bub | In LinkedIn on your laptop, ⌘⇧V | Free |
| Kondo | In Kondo's inbox | Paid, from $28/user/mo yearly |
Some automation tools send AI-generated or pre-recorded voice notes in bulk. That's the opposite of what makes voice work, and automation is what LinkedIn restricts accounts for.
Questions
Do LinkedIn voice notes increase reply rates?
They tend to get noticed more than text because they're clearly personal, especially as a follow-up. They don't fix a bad target or a weak reason to talk, and generic voice notes sent at volume lose the effect.
How long should a LinkedIn voice note be?
20 to 40 seconds. LinkedIn's limit is one minute.
Should my first LinkedIn message be a voice note?
Usually not to a stranger. Start with a short text or connection note, and use voice once they've accepted or replied.
What's the best tool to send LinkedIn voice notes?
On a phone, the LinkedIn app. On a laptop, Bub, a free Chrome extension that adds a record button to LinkedIn's message box.
Are AI voice notes a good idea?
Rarely. The point of a voice note is that it's really you; a synthetic or mass-produced one tends to be spotted and works against you.
