Understanding these LinkedIn character limits allows you to optimize your communication on the platform.

LinkedIn Message Character Limit: Connection Requests

For Connection Requests: 300 characters for premium users and 200 characters for free users (including spaces & Punctuation)

For InMail Messages:

  • Subject Line: 80 characters.
  • Message Body: Up to 300 characters for free accounts and up to 1900 characters for premium LinkedIn accounts.

The key to growing your LinkedIn network lies in mastering the usage of connection messages and InMail messages. Yet, many people are unaware that LinkedIn outreach communications come with character constraints. They often compose a connection note without realizing it may exceed the permissible limit, leading to less effective outreach.

Connection and InMail Messages

First and foremost, what exactly are connection messages, and how do they differ from InMail messages? When you want to connect with someone on LinkedIn, you can leave a connecting message. Although this function is optional, marketers should always use it to boost their chances of striking a connection.

You cannot send messages to people who are not connected to you if you have a basic LinkedIn account (which is free). Only people in your network and members of the same LinkedIn Groups can send messages to each other.

You can use InMail to send messages to folks who aren’t on your network. You can obtain a certain amount of InMail based on your plan if you sign up for a paid LinkedIn account.

You get three InMail messages each month with the Career plan, and 15 with the Business plan. The Sales plan allows you to send up to 20 InMail messages per month, while the Hiring plan allows you to send up to 30. Select a strategy that will assist you in achieving your LinkedIn outreach objectives.

You can still join LinkedIn Groups and send messages to people outside of your network if you don’t want to pay for a premium membership.

LinkedIn Groups

Why should you utilize InMail to connect with fresh leads?

LinkedIn InMail is the company’s equivalent of email, created specifically for its platform. You can only send direct messages to people you’re linked with (or in the same LinkedIn group) if you have a basic (free) LinkedIn account. If you don’t have a premium LinkedIn account, another option is to join a mutual LinkedIn group and send messages to the group’s members without interacting with them.

InMail campaigns, on the other hand, are an ad format similar to email that is delivered to a LinkedIn user’s personal message inbox. The InMails are sent on a pay-per-send basis, and depending on the target population, might cost anything from $0.30 to $1 each send.

Essentially, LinkedIn provides you with a set number of credits based on your subscription level when you use InMail.

How long can LinkedIn messages be?

LinkedIn messages come with specific character limits depending on the type of message and your account type. For standard connection messages, the limit is 200 characters for free users and 300 characters for premium users.

Is there a DM limit on LinkedIn?

The subject line of a LinkedIn InMail message can be up to 200 characters long, and the body paragraph can be up to 2,000 characters long. If you want to attract your leads’ attention, you’ll need to make the most of detailed and quality content.

When compared to a typical cold email, InMail can create greater response rates if done correctly. They can also be used to start warm dialogues with your prospects. You can immediately attract their attention from the many other messages that get lost in their inbox by using a compelling subject line.

How to send longer messages on LinkedIn?

If you’re wondering how to send longer messages on LinkedIn, the answer lies in upgrading to a premium account or using LinkedIn InMail. Free accounts have limited message lengths and can only message first-degree connections. With a premium plan, you unlock the ability to send InMail messages to users outside your network with up to 2,000 characters in the message body and 200 characters in the subject line. 

Alternatively, joining mutual LinkedIn groups also allows non-connection messaging. Using tools like LinkedFusion, you can also automate and personalize longer outreach messages at scale.
