Connections and DMs

Why you can't DM them

You wrote the post, they commented, and LinkedIn still won't let you message them. Here is what is going on, and what to do about it.

The short answer

LinkedIn lets you send a normal message only to 1st-degree connections. To reach anyone else you need InMail credits, an Open Profile on their side, or for them to connect with you first. On a post that travels, most commenters are not your connections.

01The rule

A 1st-degree connection is someone who accepted your request or whose request you accepted. You can message them freely. For everyone else, LinkedIn shows a Connect button instead of a Message button, or asks you to pay with InMail.

  • 1st-degree: message any time, free.
  • 2nd and 3rd-degree: send a connection request, or use InMail credits (Premium).
  • Open Profile: some members allow messages from anyone. You still need Premium to send them one.

02Why most commenters are not your connections

A post that does well is shown to your connections' connections, and to people who follow you without being connected. Those are exactly the people who comment on a giveaway.

03Three ways to get them the link

OptionWhat it costsThe catch
Ask them to connect, then DMNothingThey have to send the request, and some never do
InMailCredits, which come with PremiumA monthly allowance that a busy post uses up fast
Put the link in a commentNothingLinkedIn tends to show posts with outside links to fewer people, and nobody lands in your DMs

Asking to connect is the one that scales, and it grows your network with people who have shown interest. Drop does it for you: it replies under the comment asking them to connect, accepts the request when it arrives, and sends the DM.

FAQQuestions people ask

Why does LinkedIn say I can't message this person?

Because you are not 1st-degree connections. Send a connection request, or use InMail if you have Premium.

Does a follower count as a connection?

No. Following someone lets you see their posts, not message them.

Will people actually connect?

Many will, because they asked for something. On the post we counted, the author's own post asked people to connect, which is the easiest way to raise that number.
