10 Best Multichannel Outreach Tools (Email, LinkedIn, Calls, WhatsApp)

McKinsey's B2B Pulse research found that B2B buyers now regularly use ten or more channels to interact with suppliers, up from five in 2016. Your prospects moved. Most outreach stacks didn't.

Here's my honest problem with most "multichannel outreach tools" lists, half the tools on them are email tools with a LinkedIn checkbox. A task reminder that tells your rep to go send a connection request isn't a channel. It's a to-do list.

So this list applies a stricter test. Which channels does the tool actually execute for you, does a reply on one channel pause the others, and what does the bill look like once real reps and real sending accounts are involved? I run outreach for a living and I've had hands on every tool here, either in our own testing for earlier guides or through live evaluation this year.

SmartReach.io opens the list because it's a cold email software where email, LinkedIn, calls and WhatsApp run as native steps of one sequence, and its Sales Engagement plans exist for exactly this job. The other nine picks each win a different scenario, LinkedIn-first sequences, enterprise cadences, database-led teams, and I've said plainly where each beats us. 👇🏼

TL;DR: the 10 best multichannel outreach tools at a glance#

How I evaluated these multichannel outreach tools#

Every tool on this list was scored on five criteria, with native channel execution weighted first. Why that one first? Ask any RevOps lead drowning in tool sprawl, the pain isn't finding outreach software, it's finding out three months in that "multichannel" meant task reminders. The five:

1. Native channel execution. Does the tool itself send the email, the LinkedIn touch, the WhatsApp message, and place the call? A checkbox that creates a manual task scores as a task manager, not a channel.
2. Cross-channel reply handling. When a prospect replies on LinkedIn, do the email and call steps stop? Sequences that keep emailing someone who already answered are how you burn goodwill at scale.
3. True cost at scale. Entry pricing hides the real bill. I modelled each tool with 5 reps and multiple sending accounts, because per-seat and per-sender models multiply in ways a pricing page doesn't show.
4. Deliverability and account safety. Email steps still need warmup, rotation and validation. LinkedIn steps need a safety model that won't get accounts restricted.
5. Where it honestly fits. Every tool gets a best-for and a switch-if, competitors included.

Why does the channel bar keep rising? According to McKinsey's B2B Pulse research, B2B buyers now regularly use ten or more channels to interact with suppliers, up from five in 2016. An outbound cadence that lives on one channel is talking to a fraction of that journey.

Scored by Lancelot Dsouza, CMO at SmartReach.io. Yes, I work at the company ranked first. The rubric was identical for every tool, the cons on our own entry are real, and I've handed wins to rivals wherever they earned them, Skylead for flat all-in pricing, Salesloft for enterprise coaching, Apollo for database depth.

Some tools you might expect here are excluded by definition, because every entry on this list must run at least two channels natively. Instantly and Smartlead are excellent email infrastructure and we rank them highly in the best cold email software guide, but they're email-only. HeyReach and Expandi go deep on LinkedIn but automate only that one channel, we cover them in the HeyReach alternatives guide. Amplemarket, Salesflow and MeetAlfred are also worth a look if none of the ten below fit, though their pricing is quote-only or their review records are thinner.

The 10 best multichannel outreach tools: full reviews#

1. SmartReach.io: Best for native email, LinkedIn, calls and WhatsApp in one sequence#

Let me answer the "email-only" framing you may have seen on competitor comparison pages, because it's wrong. SmartReach.io runs email, LinkedIn, calls and WhatsApp as native steps of a single sequence on its Sales Engagement plans, with reply-pause working across all four channels. A sequence can open with an email, follow with a LinkedIn touch, place a call through the built-in dialer, then send a WhatsApp message, and the moment the prospect replies anywhere, everything stops. That cross-channel pause is the single feature I'd tell you to test first in any trial, ours included.

The channel breadth sits on top of the deliverability suite the platform is known for, warmup, inbox rotation, ESP matching and free email validation, plus a built-in B2B lead finder with 300M+ verified contacts from 50M+ companies. Pricing scales by active prospects, and every plan above Basic includes unlimited users and unlimited sending email accounts, so hiring rep number six changes nothing on the invoice.

The four channels and the branch in one view. If a phone number exists the prospect gets a Day 3 call, if not a LinkedIn invite.

Here are the core multichannel capabilities of SmartReach.io 👇🏼#

• Four native channels: Email, LinkedIn automation, calls and WhatsApp in one cadence on the multichannel outreach platform, with conditional branching between steps.
• Cross-channel reply-pause: A reply on any channel pauses the whole sequence, including replies from anyone else at the prospect's company.
• Built-in dialer: Cold calling with reach across 200+ countries, call notes and recordings logged against the prospect.
• Two LinkedIn modes: A semi-automated Co-pilot by default, plus full LinkedIn automation as a $29 per account add-on on Plus plans and above, so you choose the safety level.
• Deliverability suite: Warmup, inbox rotation, ESP matching, blacklist monitoring and unlimited validation included, with sending capped at 200 emails/day per account to protect domains.
• Agency mode: Sub-accounts, white-label client dashboards, role permissions and leaderboards.

How much does SmartReach.io cost?#

Email-only teams can start on the Email Outreach plans from $29/mo and upgrade when they add channels.

Cost at scale (5 reps, multichannel): ~$99/mo total on Sales Engagement Plus. The per-seat tools below run $250 to $500/mo for the same team.

2. Reply.io: Best for AI-led multichannel cadences#

Reply.io covers the widest channel list here, email, LinkedIn, calls, plus SMS and WhatsApp tasks, wrapped in its Jason AI SDR agent. In testing, the AI Variables feature produced openers that read per-prospect rather than mail-merged, which is still rare. The catch hasn't changed since our earlier reviews, per-seat pricing climbs fast once you stack channels, and the LinkedIn integration needed a reconnect twice during my test window.

Reply.io leads with AI. Jason AI builds and runs the multichannel cadence from your data sources.

Here are the core capabilities of Reply.io 👇🏼#

• Jason AI SDR: Generates and runs multichannel sequences semi-autonomously.
• Five channels: Email, LinkedIn, calls, SMS and WhatsApp in one cadence.
• Built-in B2B database: 140M+ contacts, credit-based.
• AI inbox triage: Auto-classifies replies by intent.

3. Lemlist: Best for personalised email + LinkedIn + calls#

Lemlist orchestrates email, LinkedIn and calls from one sequence builder and remains the leader in per-prospect image and video personalisation. A campaign can open with a profile visit, send a connection request, follow with an email carrying the prospect's logo rendered into a custom image, then queue a call. The multichannel tier also adds WhatsApp and SMS. The builder is fiddlier than it should be for branching logic, and there's no native spam test, but nobody else ships visuals like this out of the box.

Lemlist's pitch is relevance at scale, AI research feeding multichannel steps.

Here are the core capabilities of Lemlist 👇🏼#

• Image and video personalisation: Dynamic visuals rendered per prospect.
• Multichannel sequences: Email, LinkedIn and calls, with WhatsApp and SMS on the top tier.
• Lead database and warmup: 650M+ lead DB plus the Lemwarm warmup layer.
• Lemcal: Bundled meeting scheduler.

Up next: Klenty ↓

4. Klenty: Best for CRM-tied teams that also cold call#

Klenty pairs email sequences with one of the better native dialers in the category, plus SMS, and its behavioural playbooks move prospects between cadences based on engagement. The CRM sync remains the smoothest I've tested, bi-directional field mapping with HubSpot inside minutes. The multichannel gap is LinkedIn, steps are task-based rather than automated, so reps still execute LinkedIn touches by hand.

Email steps and dial sessions in one sequence, with call coaching layered on top. That's Klenty's version of multichannel.

Here are the core capabilities of Klenty 👇🏼#

• Native dialer: Power dialing with recordings and dispositions in higher tiers.
• Behavioural playbooks: Auto-move prospects between cadences on engagement signals.
• Deep CRM sync: HubSpot, Pipedrive, Salesforce, Zoho.
• Agentic Cadences: AI-drafted steps and research.

Up next: Apollo.io ↓

5. Apollo.io: Best for database-led multichannel outbound#

Apollo bundles a 210M+ contact database with email sequences, a dialer and LinkedIn tasks, which is why it appears in nearly every outbound stack conversation. The database is the real product, prospect search feels closer to Sales Navigator than to an email tool. As a multichannel executor it's mid-pack, LinkedIn is task-based, and deliverability tooling is thinner than the dedicated senders, most serious users bolt on separate warmup.

Apollo sells the database first. Sequences, calls and LinkedIn tasks ride on top of it.

Here are the core capabilities of Apollo.io 👇🏼#

• 210M+ contact database: Verified emails and direct dials across 35M+ companies.
• Sequences + dialer: Email steps with native calling and recordings.
• LinkedIn extension: Push profiles into sequences from Chrome.
• Intent and AI: Buying signals and AI writing on higher tiers.

Up next: Skylead ↓

6. Skylead: Best for LinkedIn + email sequences at one flat price#

Skylead runs LinkedIn and email in one smart sequence with if/else branching, on cloud infrastructure with a dedicated IP per account, and puts every feature on a single $100/user plan. No tiers, no add-ons, connection requests, InMails, email steps, image and GIF personalisation, email discovery and verification all included. That honesty is rare in this category. The limits are the flip side, there's no dialer and no WhatsApp, and per-user pricing adds up across a bigger sender pool.

LinkedIn automation and cold email in one smart sequence, Skylead's whole pitch in a single hero.

Up next: Waalaxy ↓

---

7. Waalaxy: Best for testing LinkedIn + email outreach on a free tier#

Waalaxy pairs LinkedIn and email sequences from prebuilt templates and is the only tool on this list with a genuine free tier. For a founder or solo SDR wondering whether a second channel is worth it, that's the cheapest possible experiment. The trade-off is architecture, Waalaxy is a Chrome extension riding your live LinkedIn session rather than a cloud tool with a dedicated IP, which is the weaker safety model, and there's no dialer or WhatsApp to grow into.

Waalaxy leads with LinkedIn and adds email follow-ups, the entry-level two-channel motion.

Up next: La Growth Machine ↓

8. La Growth Machine: Best for conditional LinkedIn + email workflows#

La Growth Machine builds visual, conditional workflows across LinkedIn, email and X, branching on whether a prospect accepted your connection request or opened your email. The workflow canvas is the draw, you design the logic like a flowchart, and it handles multi-identity sending (an identity is one LinkedIn account plus its email). Calls exist as task steps rather than a native dialer, and billing per identity means multi-sender setups need the math done upfront.

All channels, one automated flow. La Growth Machine's canvas is the clearest look at conditional multichannel logic.

Up next: Salesloft ↓

9. Salesloft: Best for enterprise revenue teams#

Salesloft runs enterprise cadences across email, calls, LinkedIn (via Sales Navigator integration) and SMS, now folded into Clari's revenue platform after the 2025 acquisition. Its Rhythm engine turns buyer signals into a prioritised task list, and the coaching layer (recording, transcription, scorecards) is a real strength. Pricing is quote-only, reportedly landing around $125 to $165 per user per month plus a platform fee, and I'll admit the uncertainty here, how pricing and roadmap evolve under Clari is genuinely hard to predict. Our Outreach vs Salesloft head-to-head covers where each enterprise option wins.

Salesloft frames outreach as prioritised seller actions. Cadences are one part of the Clari-era platform.

Up next: Outreach.io ↓

10. Outreach.io: Best for large Salesforce-anchored orgs#

Outreach executes email, calls and SMS in deep, governed sequences, with the tightest Salesforce integration in the category and agentic AI deal features layered on. Implementation is measured in weeks and there's no public pricing or free trial, so it's an enterprise purchase by definition. Under 50 users it's more platform than the job requires. At 200 users on Salesforce, it often wins by default.

Outreach now sells AI agents for revenue teams. Sequences sit inside a much bigger enterprise platform.

Which multichannel outreach tool fits your use case?#

Not every team needs all four channels. Here's the shortlist by the channel mix you're actually adding.

Best for email + LinkedIn sequences#

SmartReach.io, La Growth Machine, Lemlist. SmartReach.io runs both as native steps with cross-channel reply-pause and a choice of semi-automated or fully automated LinkedIn. La Growth Machine wins on branching workflow design, Lemlist on visual personalisation inside the same cadence. If LinkedIn is the lead channel, our guide to LinkedIn outreach automation tools ranks that category on safety in depth.

Best for teams that also cold call#

SmartReach.io, Klenty, Salesloft. SmartReach.io's built-in dialer reaches 200+ countries and call steps sit inside the same sequence as email and LinkedIn, so a no-answer rolls the prospect to the next touch automatically. Klenty's dialer is excellent for CRM-tied teams, and Salesloft's calling plus coaching stack is the enterprise pick.

Best for WhatsApp outreach#

SmartReach.io, Reply.io, Lemlist. SmartReach.io includes WhatsApp steps on its Sales Engagement plans alongside the other three channels. Reply.io and Lemlist offer WhatsApp on their upper tiers. One honest caveat, WhatsApp response norms vary a lot by region and buyer type, it performs strongly in markets where business WhatsApp is normal and can feel intrusive where it isn't, so A/B it against your ICP before making it a core step.

Best for LinkedIn-first teams and agencies#

SmartReach.io, Skylead, Waalaxy. SmartReach.io is the agency pick, white-label client dashboards, sub-accounts and prospect-based pricing that doesn't charge for extra users, with email, calls and WhatsApp ready when clients want them. Skylead suits teams running LinkedIn + email at a flat all-in price, and Waalaxy is the free way to validate the motion. If you only ever need LinkedIn, the pure specialists (HeyReach, Expandi) are covered in our LinkedIn automation guide linked above.

Best for enterprise cadences#

Salesloft, Outreach.io. Both assume Salesforce, sales ops and an annual contract. Everyone else on this list will get a mid-market team live faster.

How to choose a multichannel outreach tool: a 5-step framework#

Feature lists won't make this decision for you. Here's how I'd pressure-test any tool on this page, ours included.

1. Count the channels that are native#

Ask the vendor to show each channel executing inside a live sequence. A LinkedIn step that creates a task for your rep is workflow software. If you're paying for multichannel, the tool should do the work.

2. Test cross-channel reply handling#

Reply to your own test campaign on LinkedIn, then watch whether the email step still fires. This one test separates coordinated cadences from parallel campaigns wearing one UI.

3. Price it at your real team size#

Per-seat at $89/user, per-sender at $79 to $99/account, or per-prospect regardless of team size. Model your actual reps and senders 12 months out. What does the invoice look like the day rep six joins? On per-seat tools that hire costs $1,000+/year before they've sent anything.

4. Deliverability still decides#

Multichannel doesn't excuse weak email infrastructure, email remains the volume channel in nearly every cadence. Warmup, inbox rotation, validation and placement testing should be included, not integrations. Our email deliverability checklist covers what to verify inside the trial.

5. Check the LinkedIn safety model#

Cloud execution with per-account limits beats browser extensions riding your live session. Ask where automation runs, what the daily caps are, and whether a semi-automated mode exists for accounts you can't afford to risk.

If you want a ready-made cadence to test with, our 7-touch multichannel sequence template is the one we hand new customers.

So, which multichannel outreach tool should you pick?#

The honest answer depends on which channels earn replies from your ICP.

If LinkedIn is your only channel, you don't need a multichannel tool at all, pure specialists like Expandi and HeyReach go deeper on that one channel and we deliberately left them off this list. If you're an enterprise revenue org on Salesforce, Salesloft or Outreach win on governance. If the database is the bottleneck, Apollo solves sourcing and sending in one bill.

For sales teams of roughly 3 to 50 reps and agencies running genuinely mixed cadences, I'd pick SmartReach.io, and here's the reasoning, not just the badge. It's the only tool here where email, LinkedIn, calls and WhatsApp are all native steps of one sequence with reply-pause across all four. Deliverability infrastructure and a 300M+ contact lead finder are included rather than integrated. And there's no per-seat pricing, plans scale by active prospects, so the multichannel stack costs ~$99/mo where per-seat rivals run 4 to 5 times that. It also works as a full sales engagement platform on those plans, if that's the shortlist you started from, see the best sales engagement platforms guide for that lens.
