Tool Evaluation · Outbound Execution Layer

We can build the motion. We can't send it.

Three tools evaluated against the gap between finished research and daily outbound activity: Lemlist, ZoomInfo, and Artisan. One recommendation, the reasoning behind it, and what we are deliberately not deciding here.

Prepared by Dallas Andrews, GTM Engineer  ·  For Naveen Thilagan  ·  August 7, 2026
The decision

Lemlist, three seats, roughly $3.1K a year

It addresses the gap we actually have, which is sending and measuring, at less than half the cost of the next cheapest option.

Recommendation · Lemlist Multichannel · 3 seats

Nate, Jack, and Dallas. Roughly $3,132/year at published list price billed annually. Budget $3.5K to absorb the WhatsApp add-on and any true-up. No implementation cost, no services engagement.

This is a sequencing and measurement purchase, not a data purchase. Our data layer is already running.

On the comparison: ZoomInfo and Artisan weren't ruled out for being weak products. Each is built for a different job than the one blocking us. The table below scores all three against our gap, not on overall product quality.
The problem

Two halves, and the second one is the bigger one

Clay and Claude already source the accounts, gate them, and write the personalized multichannel copy per contact. That work is finished and sitting idle.

Half one · Capacity

The motion is being run by hand

Nate and Jack execute every step manually. That caps us near 30 emails a day per inbox, and every LinkedIn touch, connection follow-up, and call step is a human remembering to do it on the right day. A hand-run sequence does not survive two BDRs carrying targets.

Half two · Measurement

We're operating on blind faith

No open, reply, or step-level data. No view into which message, which channel, or which sequence position is producing. No way to test one version against another. We can add more activity, but we cannot tell you which activity worked, so we can't get better on purpose.

Why measurement is the bigger half. More activity without measurement produces more of whatever we're already doing. The point of an execution layer is being able to see which parts work and change the rest.
Side by side

The three options, side by side

Judged against what the motion needs to run daily across two BDRs in two geographies: multichannel sequencing, conditional logic, measurement, WhatsApp for the UK, deliverability control, and fit with the stack we already run. Each tool scored on the job we need done today, not on overall product quality.

  Lemlist ZoomInfo Artisan
Built for Multichannel sequencing and execution Data, contact intelligence, and intent AI SDR, autonomous prospecting
Multichannel sequencing Yes, email, LinkedIn, WhatsApp, SMS, and dialer native in one sequence Partial, engagement module exists but sequencing is not the core product Partial, runs its own sequences rather than ours
Conditional steps Yes Limited Handled by the agent, not by us
A/B testing and step stats Yes, measured per variant Partial Agent-side, limited operator visibility
WhatsApp for the UK Yes, add-on on the Multichannel plan No No
Sending identities and deliverability 5 senders per user, with inbox rotation and warmup, so volume doesn't burn the sending domain Varies by module Managed by the vendor
Overlaps what we already own No, it's the missing layer Heavily, duplicates the Clay data layer Partly, brings its own data and copy generation
Cost per year, nearest comparable plan $3,132
Multichannel, 3 seats. Published list price.
~$15,000
SalesOS Professional, 3-seat minimum. Third-party reported.
~$7,200
Entry plan. Third-party reported.
On the numbers: only Lemlist publishes pricing, so it's the only figure here that is exact. ZoomInfo and Artisan are sales-led. Their figures are third-party reported entry points for the nearest comparable configuration, not quotes, and either could come in higher or lower. Neither would be comparable without an actual quote.
Option 1 · Recommended

Lemlist

Sequencing and measurement are its core product rather than an add-on module.

  • Conditional stepsIf a prospect accepts the LinkedIn connection, the sequence branches to the next touch automatically. A different path runs if they don't. Doing this by hand means a rep checking every pending connection request daily and remembering where each one left off.
  • A/B testingSubject lines, copy, and channel order tested against each other and measured per variant. This is how the copy gets better on evidence instead of on opinion.
  • AI and voice touchesAI-assisted steps and personalized voice notes, so these touches aren't limited by how much time is left in a rep's day.
  • WhatsAppDirectly relevant to Jack's European territory, where it's a standard business channel. We have no way to run it today at any volume.
  • Five senders per userFifteen sending identities across three seats. This partly addresses the additional-inbox constraint on its own, which is a cost we would otherwise carry separately.
Limitations

What it isn't

Its native data is thinner than ZoomInfo's, and its AI personalization is less sophisticated than Artisan's. Neither matters much here: Clay handles our data and Claude writes our copy. We're buying the send-and-measure layer specifically.

Compliance posture

Ready for security review

SOC 2 Type 2 report available, GDPR compliant, data hosted in the EU on French infrastructure, DPA available on request. EU hosting is worth surfacing to security up front rather than having it come back as a question.

Option 2 · Not now

ZoomInfo

A stronger data product than the one we run today. It solves a problem we don't currently have.

Stated plainly: ZoomInfo covers most of what we use Clay for, and more besides. On a clean-sheet comparison of the two data layers, it is arguably the better tool.

That is not the decision in front of us, for two reasons.

Reason one

It doesn't solve the gap

Our bottleneck is sending and measuring, not sourcing. We already have more qualified, enriched, gated contacts with finished copy than we have any way to contact. Buying more and better data makes the backlog larger, not smaller.

Reason two

The data layer is already funded and live

We've put roughly $5K into proving out Clay and that build is running today, with the gating and personalization logic on top of it. Swapping the data layer now means rebuilding that work, at several times the cost, to solve a problem we don't have.

Worth revisiting, on a different clock. The Clay versus ZoomInfo data-layer question is a legitimate one and it should get a real look at renewal, with usage data from a motion that's actually running. It is a separate decision from this one, and bundling them would delay both.
Option 3 · Revisit later

Artisan

Worth keeping on the list. A nice to have, not a need to have.

Artisan is a strong product. Its AI personalization and its native live cold-call assist are the features worth watching, and they are the reason it stays on the list rather than off it.

The fair point in its favor

It doesn't have to replace the rep

Artisan gets framed as an AI SDR that substitutes for a person, and it can be run that way, but that isn't the only way to use it. It can be pointed at augmenting reps we already have. The common objection to it is a choice about deployment, not a property of the product.

Why not now

Wrong sequence, wrong price point

It brings its own data and its own copy generation, both of which we already have, and it costs several times Lemlist while giving us less direct control over our own sequences. Buying an AI layer before we have a measured baseline means we couldn't tell whether it was working.

The order that makes sense: get the motion running and measured on Lemlist first. Once there's a baseline, Artisan becomes a decision we can evaluate against real numbers rather than a bet. The cold-call assist in particular is worth a second look then.
Scope

What this evaluation is not deciding

Three adjacent questions this doesn't answer.

The data layer stays Clay

Not up for review here. It's funded, live, and carrying the gating and personalization logic. Revisit at renewal with usage data in hand.

The AI SDR question stays open

Artisan is parked, not rejected. It gets a real look once there's a measured baseline to judge it against.

The inbox and dial-number line item is separate

A small related spend for additional sending inboxes and native numbers. Lemlist's five-senders-per-user allowance reduces it. Worth raising on its own so it doesn't slow this approval down.

Recommendation

Approve Lemlist. Open security review in parallel.

Three seats on the Multichannel plan, roughly $3.1K a year, budgeted at $3.5K. It's the lowest-cost option of the three, and the one aimed at the gap we actually have.

Vendor documentation is available now: SOC 2 Type 2, GDPR, EU hosting, DPA on request.

ZoomInfo and Artisan figures are third-party reported entry points from public 2026 pricing analyses, not vendor quotes. The ~$5K Clay figure is our own spend to date and should be reconciled against the credit ledger before it's quoted outside this doc.
