What is the right length for a cold DM on LinkedIn?
+
Short enough to read on one phone screen without scrolling, which for most people means somewhere between 250 and 450 characters in two or three brief paragraphs. LinkedIn allows much longer messages, but a long first message from a stranger looks like a brochure. If the person already knows you from the comments, you can go shorter still.
Do cold DMs on LinkedIn still get replies?
+
Some do, but a message to a complete stranger has the lowest reply rate of any kind of outreach covered here. The ones that work are specific about why this person, honest about being cold, and end with a question that takes seconds to answer. Reply rates are noticeably higher once the person has seen your name several times, which is why warming a lead through comments first is worth the weeks it takes.
What should the first line of a LinkedIn DM say?
+
It should say why you are writing to this particular person. Refer to something real: a post of theirs you commented on, their reply to you, their comment on your post, or a visible change at their company. Skip greetings that could go to anyone, and skip your job title. The first line is what shows in the preview, so it decides whether the rest is read.
How many comments should I leave before I message someone?
+
There is no fixed number, but one comment is rarely enough. A useful rule is to wait until you have commented on four or five of their posts over a few weeks, or until they reply to one. Icebreakly tracks this as a touch count for each lead and labels the stages Stranger, Familiar at about five touches, Trusted at about twelve, and Warm at twenty or more.
Does Icebreakly send these DMs for me?
+
No. Icebreakly does not send direct messages, connection requests, InMail or follow-up sequences. It monitors the LinkedIn profiles you choose, drafts a comment in your voice when one of them publishes a post, and posts it after your approval or on Autopilot. The messages on this page are for you to send yourself once a lead knows your name. If you need DMs sent automatically at volume, a sequencer is the right tool for that, and some teams run one alongside.
Can I use AI to write a LinkedIn DM?
+
You can use it to tidy a draft, but be careful about letting it write the opening. A generated first line tends to sound like every other generated first line, and readers have learned to spot it. The parts that make a DM work are facts only you have: which post you commented on, what they said back, what you actually think. Write those yourself and keep the message short.
Is InMail better than a DM for reaching someone cold?
+
They solve different problems. InMail is a paid LinkedIn feature that lets you write to people you are not connected to, using a limited number of credits. A DM is free but normally needs a connection first. Neither changes the real difficulty with a cold message, which is that the reader does not know you. A lead who recognizes your name will usually accept an invite, and after that an ordinary DM is all you need.
Should I follow up if my DM gets no reply?
+
Once. Wait about a week and send a brief note that adds something new, such as a relevant example or a shorter version of your question. Do not send “just bumping this”. If the second message also goes unanswered, stop messaging and return to commenting on their posts. Silence usually means the timing is wrong, and staying visible in public keeps the door open without pressure.
