Key Insights - LinkedIn Inmail

What Is LinkedIn InMail?

Here, the topic LinkedIn inmail is covered with practical examples. Reaching somebody you have never connected with is the entire point of LinkedIn InMail, a premium message that sidesteps the first-degree requirement. Credits are limited, which is exactly why reply rate matters far more than send volume.

InMail messages are available through LinkedIn Premium, Sales Navigator, and Recruiter subscriptions. Each subscription tier comes with a different monthly InMail allocation.

How InMail Differs From Regular Messages

Available on free plan	Yes	No
Monthly limit	Unlimited	Varies by plan
Credit refund	N/A	Yes, if replied within 90 days
Subject line	No	Yes
Character limit	Same	Same
Response rate	Higher (known contact)	Lower (cold outreach)

InMail Allocations by Plan

• LinkedIn Premium Career: 5 InMail credits per month
• LinkedIn Premium Business: 15 InMail credits per month

How to Send an Effective InMail

Step 1: Research Your Recipient

Before writing a single word, study the recipient's profile. Look at their recent posts, job history, shared connections, and interests. This research informs your personalization and shows the recipient you have done your homework.

Step 2: Write a Compelling Subject Line

Your subject line determines whether your InMail gets opened. Keep it short, specific, and relevant to the recipient. Avoid generic phrases like "Great opportunity" or "Quick question."

Strong subject lines:

• "Your post on [topic] sparked an idea"
• "Fellow [industry] professional with a question"
• "[Mutual connection] suggested I reach out"

Step 3: Lead With Value

Open your message with something relevant to the recipient, not about yourself. Reference their work, a shared interest, or a specific challenge their company faces.

Step 4: Be Concise

Keep your InMail under 150 words. Longer messages see significantly lower response rates. Get to the point quickly and clearly.

Step 5: Include a Clear Call to Action

End with a specific, low-commitment ask. Instead of "Let me know if you want to chat," try "Would a 15-minute call next Tuesday work to discuss this?"

InMail Best Practices

• Personalize every message: Templates are obvious and get ignored. Reference specific details from the recipient's profile.
• Send during business hours: InMails sent Tuesday through Thursday during business hours see the highest open rates.
• Follow up thoughtfully: If you do not get a response, wait at least a week before following up. One follow-up is acceptable; multiple follow-ups are not.
• Track your metrics: Monitor your InMail acceptance rate and adjust your approach based on what works.
• Avoid attachments in first messages: They can trigger spam filters and make your message feel like a mass blast.

Common InMail Mistakes

• Sending the same template to everyone
• Writing long paragraphs about yourself or your company
• Being too aggressive with the ask
• Not researching the recipient beforehand
• Using clickbait subject lines
• Sending InMails on weekends or late at night

When to Use InMail vs. Other Outreach Methods

InMail is most effective when:

• You have no mutual connections for a warm introduction
• The recipient is a senior decision-maker unlikely to accept connection requests
• You need to make a professional first impression
• You are recruiting for a specific role

Consider alternatives when:

• You share mutual connections who can introduce you
• The person is active in LinkedIn Groups where you can engage naturally
• You can engage with their content first to build familiarity

Frequently Asked Questions

Is InMail worth paying for?

If you rely on LinkedIn for sales, recruiting, or business development, InMail is a valuable tool. The credit refund system means you only lose credits on messages that go completely unanswered. For casual networking, connection requests and content engagement are sufficient.

What is a good InMail response rate?

The average InMail response rate is around 10-25%, depending on your industry and targeting. Well-personalized InMails from relevant senders can see response rates above 30%.

Can you send InMail to anyone?

You can send InMail to most LinkedIn members. However, some users opt out of receiving InMail messages in their privacy settings, in which case you will not be able to reach them through this channel.

Do InMail credits expire?

Unused InMail credits roll over month to month but expire after 90 days. Credits returned from responded messages also follow this expiration cycle.

What happens if someone does not respond to my InMail?

If the recipient does not respond within 90 days, you lose that InMail credit. The message remains in their inbox and they can still respond later, but the credit will not be returned after the 90-day window.

Does InMail have a character limit?

InMail follows the same character limit as a regular LinkedIn message. What sets it apart is reach, not length. It can reach any LinkedIn member, while a regular message only reaches first-degree connections.

Can regular LinkedIn messages include a subject line?

No, subject lines are an InMail-only feature. Regular messages skip straight to the body text, which is one more reason a strong InMail subject line matters so much for getting the message opened.

How long should an InMail message be?

Keep it under 150 words. Longer messages see significantly lower response rates, so the goal is to make the point fast and let the call to action do the work.

What is Open Profile on LinkedIn?

Open Profile is a Premium setting that lets any LinkedIn member send you InMail free of charge, without using one of their credits. Turning it on works like a standing invitation for cold outreach.

When is the best time to send an InMail?

Tuesday through Thursday during business hours sees the highest open rates. Sending on weekends or late at night is one of the most common InMail mistakes, so timing is worth planning around.
