LinkedIn InMail – An overview and some alternatives

Discover folk - the CRM for people-powered businesses

LinkedIn is a great platform to build your professional network and personal brand. It's also a great channel for Founder-led, as well as social sales. But reaching out to someone can be limiting unless you've got LinkedIn premium. Which gives you access to LinkedIn InMails so that you can reach out to more people. In this blog post, we do a deep dive into LinkedIn's InMail messaging feature and look into best practices as well as some alternative solutions.

What is LinkedIn InMail?

LinkedIn InMail Messages is a premium feature. It lets you message another LinkedIn member that you're not connected to. This is particularly useful for recruiters, sales professionals and marketers.

What are LinkedIn InMail credits?

LinkedIn InMail messages operate on a credit based system. The number of credits you get determines how many messages you send. These are based on your subscription plan, which you can check from your 'My Premium' page. Note that if a member has the 'Open Profile' Premium feature enabled, you can message them for free.

What is the difference between messaging on a basic LinkedIn account and LinkedIn InMail messages

If you're using a free LinkedIn account, then you can only directly message LinkedIn members that you’re connected to. You have to upgrade to a Premium account to use InMail messages.

Limitations of LinkedIn InMail

There are a few limitations you need to be aware of, especially if you're using InMail messages for the first time:

  • No CRM integration: There isn't a CRM integration which makes it hard to get an overview of who you last contacted and when,
  • Daily sending limits: The number of messages you can send depend on the amount of credits you have, which are determined by the subscription plan you're on.
  • Character limit: InMail messages have a character limit. The maximum length for an InMail message is 2,000 characters, including spaces. The subject line has a 200 character limit.
  • Dependent on LinkedIn profile settings: You can’t message a member if they’ve chosen not to receive InMail in their message preferences settings.

Best practices for writing InMail Messages

There isn't a LinkedIn InMail template, but LinkedIn suggests the following best practices to increase your response rates.

  1. Be clear: Be brief and to the point,
  2. Share your goal and any common associations: You might want to mention something that prompted you to reach out, any mutual experiences or connections, or what you're hoping to achieve by reaching out,
  3. Use a conversational tone in your message: Choose words that reflect your personal tone of voice and keep it collaborative – how can you help them in their goals?
  4. Don't just send a link: Don't copy and paste a job description or URL to a job post in your message,
  5. Entice them: Give them a reason to reply by asking for advice, opinions or referrals.

How to send an InMail message

Ready to send your first InMail message? Once you're logged into your LinkedIn account, simply:

  1. Go to the profile of the member you’d like to send an InMail message to. (Or search for a member and send a new InMail message from the messaging page or conversation windows.)
  2. Click the More button on their introduction section.
  3. Select Message [Name of the member] from the dropdown.
  4. Type the Subject field (optional) in the New message pop-up window.
  5. Type the message in the text box.
  6. Click Send.
