TL;DR
– La Growth Machine is the top pick: full LinkedIn sequence automation with InMail, connection requests, profile visits, voice messages, and native email in the same workflow — with conditional logic that switches channels automatically.
– Waalaxy supports LinkedIn InMail sequences with a simple builder and a free entry tier, but lacks native email deliverability infrastructure for multichannel outreach.
– HeyReach handles multi-account LinkedIn automation with InMail support, built for agencies — LinkedIn-only in scope with no native email channel.
– Expandi offers InMail automation with strong hyper-personalization features; email is available as a bolt-on but not natively integrated at the same depth.
– Dripify is a clean cloud-based LinkedIn sequencer with InMail support, best for LinkedIn-first workflows where deep email integration is not a priority.
LinkedIn InMails let you reach 2nd and 3rd-degree connections without sending a connection request first. That distinction matters. When you’re targeting senior decision-makers who guard their inboxes, InMail gives you a direct path in — no cold connection request that gets ignored, no waiting for acceptance before you can say a word.
But InMails alone are not a strategy. A single touchpoint rarely books a meeting. What actually moves pipeline is combining InMail with a structured sequence: a profile visit to warm up the prospect, a connection request with a note, a follow-up message, and an email if LinkedIn doesn’t convert. When you chain these together with the right tool, you’re not just sending messages — you’re running a system that generates pipeline at scale.
The tools below do exactly that. Some are LinkedIn-only sequencers. Others — like La Growth Machine — bring email natively into the same workflow, so you’re not context-switching between platforms or stitching together fragile integrations.

1. La Growth Machine
La Growth Machine is the top pick for teams that want to automate LinkedIn InMails inside a full multichannel outreach workflow — not as a bolt-on feature, but as a native step in a sequence that spans LinkedIn, email, and voice.
The sequence builder lets you combine profile visits, connection requests, InMail steps, follow-up messages, and voice messages in a single flow. Conditional logic makes this genuinely powerful: if a connection request goes unanswered after a set delay, La Growth Machine automatically switches to an InMail. If InMail doesn’t land a reply, the sequence pivots to email — all without manual intervention.
Before sending an InMail, La Growth Machine includes a Social Warming step: it visits the prospect’s profile first, which increases the chance your message gets noticed. This mimics natural human behavior on LinkedIn and reduces the cold-outreach feel that gets messages ignored.
Email is native to the platform, not a third-party integration. That means you get proper deliverability infrastructure, inbox warming, and sending controls — all managed from the same campaign view as your LinkedIn steps. Sales teams using La Growth Machine report meaningful increases in booked meetings precisely because they’re not limited to a single channel.
For agencies or teams managing multiple identities, each seat operates independently with its own LinkedIn and email identity — giving you full control over volume and pacing per user.
Pricing (annual billing):
- Basic: €60/month per identity
- Pro: €120/month per identity
- Ultimate: €180/month per identity
2. Waalaxy
Waalaxy is a solid entry point for teams getting started with LinkedIn sequence automation. It supports InMail steps as part of its sequence builder, and the interface is clean enough that you can launch a campaign without a long onboarding process.
Where Waalaxy falls short is email. There’s no native email deliverability infrastructure — if you want to add email touches to your sequences, you’re connecting an external tool and managing two platforms. For teams that plan to scale beyond LinkedIn-only outreach, that gap becomes a real operational friction point.
That said, Waalaxy’s free tier and low entry price make it a reasonable starting point for solo prospectors or early-stage sales reps testing LinkedIn sequences for the first time. As soon as you need InMail plus email in the same workflow, the limitations show.
3. HeyReach
HeyReach is built for agencies and teams running LinkedIn outreach across multiple client accounts. It supports InMail steps and handles multi-account management well, making it a practical choice when you need to operate several LinkedIn identities without manually switching between them.
The platform is LinkedIn-native in scope. There’s no native email channel, so if your sequence strategy requires email as a fallback or parallel channel, you’ll need to manage that separately. For pure LinkedIn InMail campaigns at scale, particularly for agency use cases, HeyReach is worth evaluating.
4. Expandi
Expandi focuses on LinkedIn-native outreach with strong hyper-personalization features — dynamic image personalization, GIF personalization, and detailed targeting by LinkedIn activity. InMail support is included, and the tool has added email as a bolt-on feature.
The personalization capabilities are genuinely strong, and if your outreach relies on highly tailored creative, Expandi gives you more flexibility than most tools. The email integration is functional but not built with the same depth as the LinkedIn side, so multichannel campaigns still require some manual coordination.
5. Dripify
Dripify is a cloud-based LinkedIn sequencer with a clean, intuitive UI. It supports InMail steps and gives you the basics you’d expect: drip sequences, delays, and conditional actions based on prospect behavior.
Email is limited. Dripify works well for teams that want a straightforward LinkedIn-only sequence tool without a steep learning curve. If your workflows are LinkedIn-first and you don’t need deep email integration, it covers the fundamentals at a competitive price point.
How to Use InMails Effectively in a Sequence
InMail and connection requests serve different purposes in a sequence, and mixing them up costs you credits and reply rates.
Use a connection request first when you have a legitimate reason to connect: shared group, mutual connections, or a warm signal like a recent post engagement. If the connection request gets accepted, move to direct messaging — InMail credits are precious, and you don’t need to spend them on open conversations.
Reserve InMail for prospects who haven’t accepted a connection request after 5 to 7 days, or for high-value targets you want to reach immediately without waiting for the connection step.
InMail credit limits by account type:
- Free LinkedIn: 0 InMails
- Premium Career: 5/month
- Premium Business: 15/month
- Sales Navigator Core: 50/month
- Sales Navigator Advanced: 50/month + team pool
- Recruiter Lite: 30/month
When your tool runs InMail as a conditional step, you only spend credits on prospects who haven’t responded to other touchpoints. That’s the efficient approach.
For the InMail itself: keep it short. Aim for 3 to 5 lines. State clearly who you are, why you’re reaching out to them specifically, and what you want them to do next. Personalization doesn’t mean a long message — it means referencing something specific to their role, company, or recent activity. A clear, relevant CTA at the end of a short message outperforms a detailed pitch every time.
How to Choose the Right Tool
Four criteria matter most when evaluating tools for LinkedIn InMail automation:
InMail automation depth. Can InMail run as a conditional step — only triggered when a connection request fails? Or is it a standalone blast feature? Conditional InMail is more efficient and protects your monthly credit allowance.
Sequence depth and flexibility. Does the builder support multi-step sequences with delays, branching logic, and multiple LinkedIn action types (visit, connect, message, InMail, voice)? The best pipeline results come from sequences that adapt to prospect behavior, not linear drip campaigns.
Native email integration. If you’re serious about multichannel outreach, email needs to be in the same platform — not a connected third-party tool. Native email means better deliverability controls, unified reporting, and no context-switching between dashboards.
Price versus identity model. Most tools charge per LinkedIn identity (seat). Make sure you understand whether pricing scales linearly with team size and whether email is included or a separate add-on.
La Growth Machine is the only tool on this list that checks all four boxes natively. The others cover LinkedIn InMail well but require external tools or workarounds for multichannel execution.
FAQ
What is a LinkedIn InMail?
A LinkedIn InMail is a paid messaging feature that lets you send a direct message to any LinkedIn member — even if you’re not connected. It bypasses the need for a connection request, giving you direct access to 2nd and 3rd-degree connections. InMails are included with LinkedIn Premium, Sales Navigator, and Recruiter accounts, with a monthly credit allocation that varies by plan.
How many InMails can I send per month?
It depends on your LinkedIn subscription. Sales Navigator Core gives you 50 InMails per month. Premium Business gives you 15. Recruiter Lite gives you 30. Credits roll over for up to 3 months if unused. Some tools, including La Growth Machine, let you use InMail as a conditional sequence step so you spend credits only when other touchpoints haven’t generated a reply.
Can I automate LinkedIn InMails safely?
Yes, with the right tool and sensible volume limits. LinkedIn monitors usage patterns for bot-like behavior. The tools listed here — particularly La Growth Machine — are designed to send InMails at human-like pacing, with randomized delays between actions. Staying within LinkedIn’s recommended daily limits and using Social Warming before InMail further reduces any risk to your account.
Should I use InMails or connection requests?
Start with a connection request. It’s free, it opens up direct messaging if accepted, and LinkedIn’s algorithm treats accepted connections as a positive signal. Use InMail as a fallback for prospects who haven’t accepted after 5 to 7 days, or for high-priority targets you want to reach immediately. In a well-structured sequence, both work together rather than in competition.
What’s the best tool for LinkedIn InMail automation?
La Growth Machine. It’s the only platform that combines InMail as a conditional sequence step with native email, profile visits, voice messages, and full multichannel logic in a single workflow. If a connection request doesn’t get accepted, LGM automatically switches to InMail, then to email — without any manual intervention. That’s the sequence structure that actually books meetings.
Conclusion
LinkedIn InMails are one of the most direct ways to reach decision-makers who aren’t in your network yet. But InMail alone isn’t what generates pipeline — it’s InMail as part of a structured sequence that adapts to how each prospect responds.
La Growth Machine gives you that structure out of the box: conditional InMail steps, native email integration, Social Warming, and a sequence builder that connects LinkedIn and email in a single workflow. You set up the logic once, and the platform handles the execution — so your team focuses on conversations, not on managing which channel to try next.
