LinkedIn InMail vs. Messages: What’s Best for Automated Outreach?

The hardest part of LinkedIn outreach isn’t writing the message. It’s getting someone to notice it in the first place.Every day, decision-makers are flooded with connection requests, sales pitches, recruiter messages, and partnership proposals. Even a well-crafted outreach message can go unread if it lands in the wrong place or reaches the wrong person at the wrong time.That’s why one question keeps coming up for sales teams and growth marketers: should you use LinkedIn Messages or LinkedIn InMails?

Use messages for warm contacts and nurturing. Use InMail for cold, out-of-network prospects or time-sensitive outreach. In this guide, we’ll compare LinkedIn Messages and InMails across response rates, automation potential, account risk, and scalability to help you choose the right strategy for your campaigns.

TL;DR

• A regular LinkedIn message is free, but it can only be sent to your 1st-degree connections or people with an ‘Open profile’ setting.
• InMail messages are a paid feature that can be sent to your 2nd—and 3rd-degree connections. Each LinkedIn Premium plan has a certain number of InMail credits.
• Sponsored Messaging (Message Ads) delivers paid messages to a targeted audience segment via LinkedIn Ads. This differs from InMail or regular messages, which enable personalized connections at the individual level.
• Combine messages and InMails to nurture leads efficiently. Send connection requests and follow up with those who accept. Reserve InMails for profiles that haven’t accepted your invite after several days. To scale this approach, you can automate sending LinkedIn messages.
• For higher reply rates, keep your messages short and personalized—and engage with people’s posts before appearing in their inbox.
• PhantomBuster builds lead lists, enriches profiles, and runs compliant outreach sequences in one workflow.

LinkedIn InMails vs LinkedIn messages: main differences

If you want to message another LinkedIn member directly, you can use InMails or regular messages. But what’s the difference between LinkedIn InMails and messages?

Here’s when to choose each option.

Recipient limitation and differences between InMail messages vs regular LinkedIn messages

With regular LinkedIn messages, you can’t send messages to people unless they’re a direct connection or they have an ‘Open profile’ tag (available to Premium accounts only).

With InMails, you can go beyond your existing connections and send messages to:

The only exception is if you send them a personalized message with a LinkedIn connection request. Plan for ~60–80 connection requests per week (12–20 per workday), adjusted to your account health and acceptance rate.

With InMails, you can go beyond your existing connections and send messages to:

• 2nd-degree connections: LinkedIn members with whom you have a mutual connection.
• 3rd-degree connections: People who are connected to someone in your 2nd-degree network.

No connection request is needed.

How many LinkedIn InMail vs LinkedIn messages you can send

For connection requests on a free LinkedIn account, keep to ~60–80/week for newer accounts and increase gradually as acceptance stays high. 1st-degree DMs aren’t hard-capped but pace them to avoid spam signals.

If you have a Premium account, you’ll also get a certain number of InMail message credits based on your account type. You can always check how many credits you have left via your Premium page and monitor your rate limits.

How do InMail credits work? You’ll get new credits on the first day of your billing cycle, every month. If someone accepts, declines, responds, or sends a Quick Reply to your InMail within 90 days, then your InMail credit will be credited back. You can’t send further messages to a LinkedIn user until they’ve replied to your first InMail.

As of June 2026, LinkedIn lists the following monthly InMail credits for each account type.

Can I use my Premium InMail credits for other plans? No—LinkedIn’s guidelines state that you can’t use Premium InMail message credits for your Sales Navigator or Recruiter subscription.

Recipient’s message preferences settings

Anyone can choose not to receive InMail messages. To do so, they must visit their account settings, select ‘Data Privacy’, and choose their preferences via ‘Messages.’

This means that even if you have a Premium subscription, your InMail is not guaranteed to reach your prospect.

On the other hand, people can’t opt out of LinkedIn messaging from their 1st-degree connections (unless they block specific profiles).

Cost of LinkedIn InMail vs message

Sending messages with a standard account is free, but you can only directly message LinkedIn members you’re connected to, or people using the ‘Open profile’ feature.

InMail messages are a Premium feature, so you must be a paying account holder to use them. Pricing as of June 2026:

LinkedIn InMail vs message analytics

Regular messages surface minimal analytics. InMail adds response rate, sent/accepted/declined counts, and pending status, available to Premium users via the InMail analytics dashboard:

• Your response rate
• The number of messages sent
• The number of messages accepted
• The number of messages declined
• Your pending InMail message count, or those with no response

Filter by rep and template, then retire any template under a defined reply rate threshold (e.g., 5%) over 100 sends. Use these metrics to retire low-response templates, double down on topics with higher acceptance, and sequence replies within 24–48 hours.

LinkedIn InMail vs sponsored messages

A LinkedIn InMail is a paid messaging feature that you use to target individuals. LinkedIn sponsored messaging (Message Ads) delivers paid messages to a targeted audience segment; it’s not a 1:1 connection and is billed via LinkedIn Ads.

Here’s how they’re different:

• The recipient: InMails are designed to connect you with a specific LinkedIn profile, whereas message ads can reach a wider group at scale.
• The goal: InMails build a personalized connection with a prospect, whereas message ads focus on lead generation goals such as conversions or website visits.

Is it better to send InMail messages or connect on LinkedIn?

Use messages for warm contacts and nurturing. Use InMail for cold, out-of-network prospects or time-sensitive outreach.

Personalized InMails give you access to a network beyond your 1st-degree connections. This works because you remove the friction of waiting for a connection request to be accepted.

Target fewer, better-matched prospects and reference a recent signal (role change, funding, or a post) in line one. Your response rates will reflect how well you match intent and context—not the number of InMail credits you have.

The best cold outreach strategies combine InMails and regular messages. InMail message credits are limited, so reserve them for profiles that haven’t accepted your invite after several days.

How to use LinkedIn InMail and messages to improve your outreach efforts

Use messages for nurturing and InMail for targeted first touches. Here’s how to build an end-to-end workflow using PhantomBuster’s LinkedIn Automations to source profiles, enrich data, and trigger compliant sequences.

Start with a lead list

First, you need a LinkedIn profile list matching your target audience. You can do this manually or save time with pre-built workflows from PhantomBuster.

How do I extract a relevant LinkedIn profile list?

Instead of manually copying leads, you can build a seamless pipeline that auto-targets the exact people you want to reach.

With PhantomBuster’s LinkedIn Search Export automation (and the Sales Navigator variant), paste one or more search URLs to extract matching profiles. You can then download them, plug them into another workflow, or visualize them in your dashboard.

This keeps your 1st-degree sequences fed with profiles that match role, seniority, and industry filters—no manual copy/paste.

How do I enrich my HubSpot leads with LinkedIn data?

You can also connect your research with your CRM platform, such as HubSpot.

By using your HubSpot account as input for PhantomBuster’s LinkedIn Profile Data Extractor automation (which extracts profile fields), you can identify which leads match your targeting criteria and prioritize them for cold outreach sequences.

Can Events and Groups feed my lead list?

LinkedIn Events and Groups can be a great place to find people in your niche. PhantomBuster’s Event Guests Export and Group Members Export automations collect attendee/member profiles into your lead list.

First, the LinkedIn Event Guests Export automation can make a list of attendees for you straight from a URL. Just remember that you need to be an attendee, too.

Second, you can try out the LinkedIn Group Members Export automation to gather a list of members. You must also be a group member to do this.

How do I automate a compliant connection + follow-up sequence?

Once you have your list of profiles, you’re ready to nurture them with a lead generation sequence—sending them a personalized connection request plus follow-up messages for those who accept.

Use PhantomBuster’s LinkedIn Outreach Flow to orchestrate the full sequence (invite → DM follow-ups → stop on reply) and reserve manual steps for edge cases. All you have to do is:

1. Provide a curated list of target profiles. You can paste a single LinkedIn/Sales Navigator search URL, upload a shared Google Sheet containing a column of profile URLs, or pull directly from a pre-executed LinkedIn Search Export automation.
2. Connect to your LinkedIn account. PhantomBuster uses cloud-based infrastructure to maintain consistent login patterns; use the official browser extension solely for authentication, then run automations in the cloud.
3. Choose how many connection requests to send and when. Pace connection requests at 15–20/day (max ~80/week) and scale only if your acceptance rate stays healthy.
4. Craft an introductory note to attach to the invitation. Use dynamic placeholder tags like #firstName# or #company#.
5. Set up your follow-up sequence to engage leads once they accept. You can script up to 3 subsequent direct messages with custom time delays (e.g., Day 2, Day 5, Day 9). PhantomBuster natively applies stop-logic where the workflow instantly freezes to let a human take over after the prospect replies.

You’ll then have your own automatic LinkedIn message sequence without having to rely on InMails just yet. Plus, this workflow can run in the background while you focus on other things.

Use InMail credits to reach out to leads who don’t reply to your connection requests

InMail credits are refunded on replies within 90 days, so response rate extends your reach—but credits remain finite. By building a connection request and follow-up sequence, you can reserve InMails for profiles that haven’t accepted your invite after several days.

You’ll avoid wasting credits on profiles that you could send regular LinkedIn messages to, and you’ll be less dependent on InMails for success.

You can also message certain out-of-network prospects for free if they have a Premium account and have enabled “Open Profile.” Within the Outreach Flow, enable the Sales Navigator InMail Sender step and select “Only send to Open Profiles” or “Do not use paid credits” so PhantomBuster detects Open Profiles and prioritizes them to avoid consuming paid credits. This allows you to scale out-of-network messaging without draining your monthly budget.

When should I switch from LinkedIn to email?

If no one has responded to your LinkedIn message or InMail, it’s time to try a different outreach channel.

Use email as your next touch when LinkedIn is silent—reference the same trigger (the role change, funding announcement, or post) and offer a clear, low-friction next step.

But what if you can’t find someone’s email address? Use PhantomBuster’s Email Discovery to append verified emails to your lead list (with bounce risk checks) before sending a short, opt-out-friendly message.

What are the best practices for InMail and messages?

Whether you send InMail or messages, there are some best practices to follow before you appear in someone’s inbox.

Pace connection requests and DMs to avoid account restrictions

Sudden spikes in invites/DMs can trigger reviews—keep a steady pace. Keep automated connection requests capped at 15 to 20 per day (maximum 80 per week). For 1st-degree DMs, avoid abrupt volume jumps and spread messages throughout the day. Keep InMails at or below your monthly credits.

Prefer cloud-run automation over browser extensions

Running automations in the cloud reduces local browser friction and helps maintain a consistent session. PhantomBuster’s cloud infrastructure handles execution remotely, so you’re not injecting code directly into your local browser session.

Maintain consistent login patterns (device, IP region) and follow platform rules to protect account health.

Use personalization

Generic variables like {{First_Name}} and {{Company_Name}} no longer cut it and often read as automated spam. Higher reply rates are driven by intent signals.

Build lists around specific trigger events such as prospects who recently changed roles, companies that just announced funding, or users who commented on a specific industry post. Reference a public signal (their post on X, recent funding) in line one and tie it to a one-sentence problem you solve.

Reference that exact trigger in your opening line to instantly build rapport. With PhantomBuster, you can use personalization tags based on the data you’ve extracted to make every LinkedIn message resonate. If you want to go further, learn how to use AI to personalize LinkedIn messages at scale.

Write short and direct messages

Keep initial messages to 100–300 characters: one context line and one low-friction question.

Aim for 100–300 characters for initial InMails; keep one ask and avoid links. Focus your message on a straightforward call to action, and you’re far more likely to get a reply.

Target ~300 characters when in doubt; test 150 vs 300 to see which yields higher reply rate. Treat your initial InMail or connection message as a conversation starter, not a sales pitch. State your context, explain your value proposition in one sentence, and close with a low-friction interest question (e.g., “Are you open to seeing how we handle this?”) rather than dropping a heavy meeting link right away.

Engage with LinkedIn users before reaching out

Treat LinkedIn like a two-way channel: interact with posts before you message. This works because you’ll get better results if you interact with LinkedIn users before sending them a message.

For example, you could follow them, comment on a post, or like something they shared. This way, you won’t be a total stranger by the time you send them a message.

Use PhantomBuster’s engagement automation sparingly (e.g., 10–20 likes/day) and prioritize genuine comments. Fold this into your outreach flow rather than running it in isolation.

Frequently asked questions

What are LinkedIn’s limits for connection requests and messages?

Connection requests should stay under ~80/week for newer accounts; ramp gradually based on acceptance rate. 1st-degree DMs aren’t hard-capped but pace them to avoid spam signals. For InMails, you’re limited by your monthly credits (5–150 depending on your Premium plan). Sudden spikes in any category can trigger account restrictions.

Do InMail credits get refunded if someone doesn’t reply?

Yes, if the recipient accepts, declines, responds, or sends a Quick Reply within 90 days, your credit is refunded. If they ignore your InMail beyond 90 days, the credit is gone. This makes targeting and message quality critical to preserving your credit pool.

What’s a realistic reply rate for InMail vs regular messages?

Warm 1st-degree messages generally outperform cold InMail; your targeting and timing drive the gap. InMail response rates vary widely (often 10–25% for well-targeted, personalized messages), while 1st-degree messages to engaged connections often see higher reply rates. Both improve with tighter targeting and intent-based messaging.

Can I send InMails without using credits?

Yes, if the recipient has a Premium account and has enabled “Open Profile,” you can send them an InMail without consuming a credit. PhantomBuster can detect Open Profiles and prioritize them to avoid consuming paid credits. This lets you extend your reach without draining your monthly budget.

How do I automate LinkedIn outreach without getting restricted?

Use cloud-based automation platforms that maintain consistent login patterns. Pace connection requests at 15–20/day (max ~80/week) and scale only if your acceptance rate stays healthy. Throttle DMs to avoid sudden spikes. Keep InMails at or below your monthly credits. Running automations in the cloud reduces local browser friction and helps maintain a consistent session.

What personalization data should I use for cold InMails?

Build lists around specific trigger events such as prospects who recently changed roles, companies that just announced funding, or users who commented on a specific industry post. Reference that exact trigger in your opening line to instantly build rapport. Generic variables like first name and company name no longer cut it and often read as automated spam.

What’s the difference between InMail and Sponsored Messaging?

InMails are 1:1 paid messages sent to specific individuals; you pay via your Premium subscription and get a monthly credit allotment. Sponsored Messaging (Message Ads) delivers paid messages to a targeted audience segment at scale and is billed via LinkedIn Ads based on impressions or engagement. Use InMail for personalized prospecting and Sponsored Messaging for broad awareness campaigns.

How do I sync LinkedIn data with my CRM?

Use PhantomBuster’s LinkedIn Profile Data Extractor automation with your CRM (e.g., HubSpot, Salesforce) as input. The automation enriches your existing CRM records with LinkedIn profile data—job title, company, recent activity—so you can prioritize leads, segment by intent signals, and trigger sequences based on role or seniority. This keeps your CRM and outreach workflows in sync without manual data entry.

The verdict: which outreach method wins for automation?

Use messages to nurture existing connections and InMail to reach out-of-network prospects when timing or access matters. Messages work best for warm contacts and follow-ups after a connection is established. InMail removes the connection-request barrier and gives you direct access to decision-makers outside your network.

The most effective approach combines both: send connection requests with personalized notes, follow up with accepted connections via direct messages, and reserve InMail for profiles that haven’t accepted after several days. PhantomBuster operationalizes this combined approach by orchestrating the full workflow—list building (Search/Events/Groups), profile enrichment (data extraction and CRM sync), the Outreach Flow (invite + DM follow-ups with stop-on-reply logic), InMail routing for non-accepts, and email handoff when LinkedIn goes silent.

Keep first touches to 100–300 characters, reference one public signal (role change, funding, or a recent post), and ask a yes/no interest question. Your reply rate will reflect how well you match intent and context—not the volume of messages you send.
