Why trust this guide?
This guide is written by the Master Inbox team and reviewed by our founder, Abdul Mukati. We work with outbound teams and agencies that run email and LinkedIn side by side, so we see the day-to-day problem: two channels, two inboxes, and a prospect who answers on the one you checked last. Master Inbox is one of the five options, and we say so plainly. We describe the other four as approaches, in general terms, with no prices, ratings or statistics, and we give each an honest list of trade-offs. See "How we evaluated" at the end.
Why manage LinkedIn and email replies together?
Multichannel outreach, where you contact the same prospect by email and LinkedIn, is common because it gives you two ways to be seen. The cost shows up on the reply side. A prospect might answer your email on Monday and your LinkedIn message on Wednesday. If those live in different tools, your team may answer one without knowing about the other, or miss one entirely.
Putting both channels in one thread per prospect means:
- Your team sees the whole conversation before answering.
- Labels and follow-up rules apply to every channel the same way.
- Reporting shows response times across email and LinkedIn together.
- Handoffs between SDRs and account executives carry the full history.

The five ways compared
| Approach | Best for | Where it fits |
|---|---|---|
| 1) Master Inbox | Outbound teams and agencies running email and LinkedIn together | The reply layer for both channels, next to your sequencers and CRM |
| 2) HubSpot with LinkedIn Sales Navigator | Teams that research and track accounts in the CRM | CRM records enriched with LinkedIn context |
| 3) A sales engagement platform | Rep-led cadences that mix email and LinkedIn tasks | Sequencing and tasks for one outreach motion |
| 4) A manual method | Solo sellers and small volumes | A starting point before tooling |
| 5) A virtual assistant service | Teams that want a person to watch both channels | A human layer on top of existing tools |
1) Master Inbox
Master Inbox is the reply management platform for outbound teams and agencies. Email and LinkedIn replies sit in one place, with one set of labels.
How it works
You connect your email sending tools, such as Smartlead, Instantly, EmailBison, Reply.io and Lemlist, and your LinkedIn tools, such as HeyReach, Expandi and Aimfox. You can also add native LinkedIn seats. The LinkedIn Inbox threads each prospect's LinkedIn messages next to their email replies, so a rep sees one conversation. Master Inbox reads the mailboxes themselves, so it also threads forwards, CC replies and new-address replies that a sequencer's own inbox does not show.
Every email and LinkedIn reply is labeled by intent through AI labeling, using thirteen default labels or your own taxonomy on your own OpenAI, Anthropic or OpenRouter key. Workflows act on labels: Slack cards with an approve button, a HubSpot sync, or a stop on the sequence when a meeting is booked. Reply Agents can answer, follow up and book meetings, human-in-the-loop first.
Pros
- Email and LinkedIn in one thread per prospect, so nobody answers in the dark.
- Works with the LinkedIn tools teams already use: HeyReach, Expandi and Aimfox, plus native seats.
- One label set and one set of workflows across both channels.
- Syncs to HubSpot, Pipedrive, Attio, GoHighLevel and Salesforce.
- Unlimited users on every plan, and reporting by channel and label in reporting.
- Every plan starts with a free 7-day POC, and onboarding is done with you.
Best for
Outbound sales teams and lead generation agencies that run multichannel outreach. See Master Inbox for outbound teams and for agencies.
Works alongside
Master Inbox works alongside your sequencer, LinkedIn tool, CRM and support desk. Keep your tools for sending, and let Master Inbox hold the replies. Pair it with HeyReach, Expandi or Aimfox, and sync to HubSpot. Plans start with Agency at $599 and Team at $799 per month, all with unlimited users, and a native LinkedIn seat is an add-on at $15 per account per month. See the pricing page.
2) HubSpot with LinkedIn Sales Navigator
HubSpot is a CRM with sales automation, and LinkedIn Sales Navigator is LinkedIn's tool for finding and tracking prospects and accounts. Many sales teams connect the two.
How it works
The integration is designed to bring LinkedIn profile and account context into CRM records, so reps can see who a contact is while they work in the CRM. Email conversations are logged on the contact record, and tasks remind reps to follow up. LinkedIn messages themselves are generally sent and received in LinkedIn, so reps move between the CRM and LinkedIn to answer them, and may log a note by hand.
Pros
- LinkedIn context next to contact and company records.
- One CRM for deals, tasks and email activity.
- Useful for account research and for tracking which prospects you have touched.
- Familiar tooling for teams that already own both.
Cons
- LinkedIn conversations typically stay in LinkedIn, so email and LinkedIn replies end up in two places.
- Cold email sent from other tools reaches the CRM only through integrations.
- Both products are usually licensed per user, so cost grows with the team.
- Labeling replies by intent across channels needs custom setup.
Best for
Teams that research and manage accounts in the CRM, and that do most LinkedIn conversation by hand. If HubSpot is your CRM, HubSpot Inbox lets you reply to outbound email and LinkedIn from inside HubSpot, and the HubSpot integration syncs labeled replies.

3) A sales engagement platform
Sales engagement platforms manage cadences for reps. Many let you add LinkedIn steps, such as a profile view, a connection request or a task to send a message.
How it works
Reps are enrolled in a cadence that mixes email steps with LinkedIn tasks. The platform sends the email, reminds the rep to act on LinkedIn, and logs activity to the CRM. When a prospect replies by email, the cadence typically pauses. LinkedIn replies are generally seen in LinkedIn, and reps record the outcome in the platform.
Pros
- Email and LinkedIn steps planned in one cadence.
- Task lists that keep reps on schedule.
- Manager visibility into rep activity.
- CRM connections keep records tidy.
Cons
- The platform sees the email it sent. Replies from other sending tools sit outside it.
- LinkedIn steps are often tasks for the rep, so the actual conversation happens in LinkedIn.
- Licensing is commonly per user, and setup takes time.
- Teams using dedicated cold email tools end up with more than one inbox.
Best for
Rep-led teams that run a defined cadence and do most work inside one platform. If you also use other sending tools, a reply layer collects the answers from all of them. See what a sequencer does.
4) A manual method
The manual method is a mailbox plus browser tabs: Gmail or Outlook for email, LinkedIn for messages, and a spreadsheet or CRM for notes.
How it works
Someone opens the email inbox, then LinkedIn, on a schedule. They read new replies, answer them and note the lead in a tracker. Labels or stars in the email client help sort, and reminders prompt follow-ups. A short checklist keeps the routine consistent.
Pros
- No cost and no setup.
- Complete control over how you answer.
- Good for learning what prospects say before you invest in tools.
- Fine for a few conversations a day.
Cons
- It is time-consuming, because every channel is checked separately.
- Replies on the channel you checked last can wait for hours or days.
- Copying notes by hand invites mistakes.
- There is no shared view, labeling or reporting for a team.
- It is hard to hand over to a new teammate.
Best for
Solo sellers and small tests. When switching between tabs becomes a daily chore, look at a shared inbox. Our DIY reply stack comparison shows what changes.
5) A virtual assistant service
A virtual assistant (VA) service gives you a person, or a small team, who monitors your inboxes and LinkedIn and helps with replies.
How it works
The assistant is given access to the email accounts and LinkedIn profiles, with a written playbook. They check at set times, tag or forward replies that need a response, answer simple ones using your templates and log leads. Some teams add a daily summary so the sales lead can see what came in.
Pros
- A person handles the checking, which frees your reps to sell.
- Can cover both channels with no new software.
- Flexible: the playbook changes when your process does.
- Useful during busy campaigns or time-zone gaps.
Cons
- Replies wait until the next check, so response times are longer.
- Ongoing cost, and quality depends on training and turnover.
- Access to mailboxes and LinkedIn profiles needs careful permissions.
- Knowledge sits with the assistant, and reporting is limited.
Best for
Teams that want human help for a defined period or for simple triage. Many teams that use an assistant give them a shared inbox so the work is faster and easier to review.
How to choose the right way
- Email and LinkedIn from several tools, and a team that shares replies: use Master Inbox. Read the unified inbox guide to see why a single thread helps.
- Account research in the CRM: use HubSpot with Sales Navigator for context, and add a reply layer for conversations.
- Rep-led cadence: use a sales engagement platform for steps and tasks, and a reply layer for responses from other tools.
- Testing LinkedIn outreach: work manually first and decide when to switch.
- Short-term help: a virtual assistant can bridge a busy period.
- Client campaigns: use separate workspaces so each client sees only their inbox. See client workspaces.
Speed matters on both channels. Measure the time from reply to response, as described in the cold email reply management guide and the speed to lead page. For wider options, see the comparison hub.

Yes, at low volume. The trade-offs are response delay, ongoing cost and the need to grant careful access, so many teams use an assistant alongside a shared inbox.
Can I keep my sequencer and my LinkedIn tool?
Yes. Master Inbox is built to work alongside them. Keep your tools for sending and use Master Inbox for the replies.
Does AI labeling work on LinkedIn replies?
Yes. Every email and LinkedIn reply is labeled by intent as it lands, using thirteen default labels or your own taxonomy.

No. Plans follow connected mailboxes and client workspaces, with unlimited users on every plan. Every plan starts with a free 7-day POC.
How we evaluated
We compared the five ways on four questions: are email and LinkedIn replies in one view, can the team tell which replies matter, how quickly does the right person see them, and how do effort and cost grow with volume. HubSpot, LinkedIn Sales Navigator, sales engagement platforms and assistant services are described as categories in general terms, with no vendor prices, ratings or statistics. Check each vendor's own pages for current features and pricing, for example LinkedIn Sales Navigator and HubSpot Sales Hub. HubSpot and LinkedIn are trademarks of their owners. Master Inbox is an independent product and is not affiliated with HubSpot or LinkedIn.
