Send attachments and voice notes in LinkedIn messages

What can I send from the Inbox reply box now?

Three things beyond plain text: file attachments, voice notes, and quoted replies to a specific earlier message. Each has its own control in the reply box, and you can combine them with your typed message — for example, attach a proposal PDF, add a line of text, and send them together.

Attachments (the paperclip)

Send a file straight into the conversation — a PDF one-pager, a case study, an image, a slide deck, a spreadsheet. The person receives it in their LinkedIn inbox exactly as if you'd attached it on LinkedIn.

Voice notes (the microphone)

Record a short spoken message right in the reply box. A quick voice note often lands warmer than text for a first reply or a thank-you, and it helps you stand out in a crowded inbox.

Quoted replies (the reply arrow)

Reply to one specific earlier message so it's clear which point you're answering — useful in a long back-and-forth where "which question are you answering?" would otherwise be ambiguous.

These controls are part of WarmySender's LinkedIn Outreach pillar. WarmySender is a 4-pillar outreach platform — Cold Emailing, Email Warmup, LinkedIn Outreach, and Multichannel sequences — and a full-featured reply box means you can run real conversations from the same place you run your campaigns.

How do I send a file attachment?

Open the conversation in your Inbox, click the paperclip in the reply box, choose the file from your computer, optionally type a message to go with it, and send. The file uploads, you'll see it attached in the reply box before you send, and it arrives in the person's LinkedIn conversation.

1. Open the LinkedIn conversation in your Inbox.
2. Click the paperclip icon in the reply box.
3. Pick the file you want to send (for example a PDF, image, or deck).
4. Wait a moment for it to attach — you'll see the file name appear in the reply box.
5. Optionally type a short message to go with it.
6. Click Send. The file lands in the person's LinkedIn inbox.

Tip: a one-page PDF or a short deck tends to get opened more than a long document — treat the attachment like the hook, not the whole pitch. You can send more than one file across a couple of messages if you have several things to share.

How do I record and send a voice note?

Click the microphone in the reply box, allow your browser to use your microphone the first time, speak your message, then stop and send. You'll be able to hear the recording back before it goes out, so you can re-record if you fluff a line.

1. Open the LinkedIn conversation in your Inbox.
2. Click the microphone icon in the reply box.
3. The first time, your browser will ask permission to use your microphone — click Allow.
4. Speak your message. Keep it short and natural — a voice note that runs 20–40 seconds usually lands best.
5. Stop the recording, listen back, and re-record if you want to.
6. Click Send. The voice note arrives in the LinkedIn conversation for the person to play.

If the microphone doesn't respond, it's almost always the browser's microphone permission — check your browser's site settings for warmysender.com and make sure the microphone is allowed, then reload the page and try again.

How do I reply to a specific earlier message?

Hover over the message you want to answer and click the reply arrow — the earlier message is quoted above your reply box so the person can see exactly what you're responding to. Then type your reply (or add an attachment or voice note) and send as usual. This keeps long conversations clear when you're answering one point among several.

Quoting is especially handy after a gap in a thread: if someone asked three questions a week ago, quoting the exact one you're answering removes all doubt about which you mean and makes your reply feel considered rather than generic.

Can I use attachments and voice notes in campaigns?

Attachments, voice notes, and quoted replies are tools for the Inbox — for the real, human conversations that happen once someone replies. Automated campaign steps stay as text so your sequence reads consistently and stays within safe, natural sending patterns. When a prospect replies and you jump into the conversation to answer them personally, that's exactly where a file or a voice note shines.

This split is intentional: campaigns do the outreach at a steady, safe pace, and the Inbox is where you add the personal, richer touches once a conversation is live. Account safety always comes first, so the richer tools live on the manual side where you're driving each message yourself.

Common adjacent questions about attachments and voice notes on LinkedIn messages in WarmySender.

What kinds of files can I attach?

Everyday business files work well — PDFs, images (like PNG or JPG), slide decks, and documents. Send the kind of thing you'd naturally share in a LinkedIn chat: a one-pager, a case study, a deck, a screenshot. If a particular file won't attach, it's usually because it's very large; try a smaller or compressed version, or share a link to it in your message instead.

Can I record a voice note in the browser?

Yes — click the microphone in the reply box and, the first time, allow your browser to use your microphone. You record right there in WarmySender, hear it back before sending, and it goes straight into the LinkedIn conversation. No app or extra software is needed; it all happens in the Inbox.

The microphone isn't working — what should I check?

Almost always it's the browser's microphone permission. Open your browser's site settings for warmysender.com, make sure the microphone is set to Allow, then reload the page and click the microphone again. If your computer has several microphones, also check the right one is selected in your system sound settings.

Can I attach a file to a campaign message?

Attachments and voice notes are for the Inbox — the personal replies you send once a conversation is live. Automated campaign steps stay as text to keep your sequence consistent and your sending pattern natural and safe. Once a prospect replies, jump into the conversation and add a file or voice note there.

Can I reply to just one message in a long thread?

Yes. Hover over the message you want to answer and click the reply arrow — that message is quoted above your reply, so the person sees exactly which point you're responding to. It's the cleanest way to answer one question among several in a busy conversation.

Will the person receive my attachment on LinkedIn itself?

Yes. Everything you send from the Inbox reply box — files, voice notes, quoted replies, and text — lands in the person's normal LinkedIn conversation. They receive and open it exactly as they would any other LinkedIn message; there's nothing they need to do differently on their end.

Can I combine a file, a voice note, and text?

You can add text alongside a file in the same message, and you can send a voice note as its own message. If you have a file, a spoken note, and some text to share, the natural flow is: send the file with a line of text, then follow with a short voice note. Sending them across a message or two also reads more naturally than cramming everything into one.
