Start FreeKanbox Inbox vs Other LinkedIn Messaging Tools
| Feature | Other Tools | Kanbox |
|---|---|---|
| Inbox layout built for LinkedIn messaging | Varies by tool: often closer to a simple chat view | 3-pane inbox like modern email: sidebar, smart filters, member list and full-screen chat |
| Conversations, network and pipelines in the same screen | Usually focused on conversations only, with network and CRM handled elsewhere | Inbox sidebar groups Conversations, My Network, Labels and Pipelines so you manage replies and stages together |
| Reply-status smart filters | Basic filters (read/unread, tags) depending on the tool | Built-in views like All, Unread, Last message sent by member, Last message sent by me and Never answered |
| Hover quick actions on each conversation | Bulk actions exist, but inline shortcuts are less central | On hover, add labels, send to a pipeline or schedule reminders without opening the thread |
| Separated batch actions for LinkedIn vs internal actions | Batch actions are often grouped under one generic menu | LinkedIn actions (send message, archive, mark read…) are queued safely; Kanbox actions (labels, pipelines, reminders, email finder) run instantly |
| Messaging, templates and AI prompts in one place | Templates often live mainly in campaigns; AI varies by tool | Use saved message templates and AI prompt templates directly from the Smart Inbox, chat and pipelines |

FAQ — LinkedIn InMail & Smart Inbox
1. What is LinkedIn InMail?
LinkedIn InMail is a Premium feature that lets you message people you're not connected with. Unlike connection requests (limited to 300 characters), InMail allows longer messages (200-character subject + 1900-character body) sent directly to someone's inbox. Available with Premium Career, Sales Navigator, and Recruiter plans.
2. How does LinkedIn InMail work?
With InMail, you can message any LinkedIn member without sending a connection request first. Each InMail uses one credit from your monthly allowance. If the recipient has an Open Profile, your InMail is free. Recipients see InMail messages in their regular LinkedIn inbox, marked as "InMail".
3. Who can use LinkedIn InMail?
InMail is available to Premium subscribers: Premium Career (5 credits/month), Premium Business (15 credits/month), Sales Navigator Core (50 credits/month), Recruiter Lite (30 credits/month), and Recruiter Corporate (150 credits/month).
4. How to send an InMail on LinkedIn?
Visit the profile of someone you're not connected with. Click "Message" or "InMail" (wording varies). Write a compelling subject line (under 200 characters) and a personalized message (under 1900 characters). Click Send. One InMail credit is deducted unless the person has an Open Profile.
5. What are the costs and limits of InMail?
InMail credits come with your LinkedIn subscription—there's no separate purchase option. Monthly allowances range from 5 (Premium Career) to 150 (Recruiter Corporate). Unused credits roll over for up to 90 days. If a recipient replies within 90 days, you get the credit back.
6. What's the difference between InMail and regular LinkedIn messages?
Regular messages are free and unlimited—but only to your 1st-degree connections. InMail lets you reach anyone on LinkedIn, but uses credits and is capped monthly. InMail messages tend to have higher open rates (they stand out in the inbox) but must be personalized to get replies.
7. What are InMail best practices?
Personalize the subject line by referencing their role, company, or recent post. Keep it short (400-600 characters get the best response rates). Lead with value—what's in it for them? Include one clear CTA. Time it right—Tuesday-Thursday mornings perform best. Follow up after 5-7 days with a connection request if no reply.
8. How effective is LinkedIn InMail?
LinkedIn reports average InMail response rates of 10-25%, compared to 1-5% for cold emails. However, highly personalized InMails can reach 35%+ response rates. The key is relevance: generic mass InMails perform poorly. Quality over quantity.
9. What are alternatives to LinkedIn InMail?
Alternatives include: connection requests (free but limited to 300 chars), Open Profile messages (free InMail to Premium users who enabled it), group messages (message members of shared groups), event attendee messages, email outreach using tools like Kanbox Email Finder, and organizing all your LinkedIn messages with Kanbox Smart Inbox.
10. How does Kanbox Smart Inbox help with InMail?
Kanbox doesn't send InMails for you—that happens on LinkedIn. But once you receive replies to your InMails, Kanbox organizes them alongside your regular messages in one unified inbox. Use filters like "Never answered" to track InMail conversations that need follow-up.
11. Can I use Kanbox without LinkedIn Premium?
Yes. Kanbox works with free LinkedIn accounts too. While you won't have InMail credits, you can still message your connections, and Kanbox helps you organize those conversations with labels, reminders, and pipelines.
12. How is Kanbox different from LinkedIn's native inbox?
LinkedIn's inbox mixes all messages in a chronological feed with ads and notifications. Kanbox gives you a full-screen, ad-free interface with smart filters (Unread, Never answered, Reminders), labels, profile context, notes, and direct pipeline integration.
13. Is Kanbox safe for my LinkedIn account?
Yes. Kanbox uses a Chrome extension that works with your existing LinkedIn session—no password sharing, no bots, no automated actions that could flag your account. You're in control of every message you send.
