Cold outreach: dynamic personalization, multichannel, warm-up, A/B, deliverability.
Before starting, we run a 1-minute tech check — microphone, ambient noise, connection. If your setup isn't good enough, the test is fully refunded.
Show recruiters and clients you actually know Lemlist inside out — multichannel sequences, bulletproof deliverability, liquid syntax personalization — proven in a 15-minute AI-led oral exam.
The Plume Lemlist badge certifies your ability to design, run, and optimize cold outreach campaigns on Lemlist end-to-end: from building a qualified audience and crafting a multichannel sequence (email + LinkedIn + cold call) to configuring Lemwarm for domain warm-up, setting up custom tracking domains, and reading campaign analytics to iterate fast. The 15-minute oral exam covers the real workflows practitioners use daily — conditional branching in sequences, liquid syntax for personalized images and videos, A/B testing on subject lines and copy, CRM sync with HubSpot or Pipedrive, lead enrichment via Lemlist Database or Dropcontact, and Zapier/Make automation.
Unlike a self-declared LinkedIn skill or a completion certificate from a pre-recorded course, the Plume badge is produced from a live AI oral exam. There are no multiple-choice questions and no way to game it by memorizing answers — the AI follows up on every claim you make, digs into real campaign examples, and surfaces your actual reasoning when things go wrong. Claude Opus then reads the full transcript and produces a score from 0 to 100 with a level (Novice / Proficient / Advanced / Expert), a detailed breakdown by dimension, and a shareable link.
This badge is built for SDRs, BDRs, growth practitioners, outbound consultants, and early-stage founders who use Lemlist regularly and need a credible, verifiable proof of skill — whether for a job application, a client proposal, an internal promotion discussion, or simply to benchmark where they actually stand versus where they think they stand.
Here are the concrete dimensions the AI examines during the 15-minute oral.
Building email + LinkedIn + cold call sequences with the right delays, conditional steps, and branching logic to maximize reply rates without burning the audience or triggering spam filters.
Using custom variables, liquid syntax, AI-generated personalized images, and dynamic video snippets to produce messages that feel hand-written at scale — and connecting those choices to measurable reply-rate lifts.
Setting up Lemwarm with progressive volume ramp-ups, configuring custom tracking domains, validating SPF/DKIM/DMARC records, handling hard vs soft bounces, and calibrating daily sending limits to protect domain reputation.
Designing statistically meaningful A/B tests on subject lines, opening lines, CTAs, and email length — defining appropriate sample sizes and calling winners based on reply rate or positive reply rate, not just open rate.
Syncing Lemlist with HubSpot or Pipedrive, enriching leads via Lemlist Database, Lusha, or Dropcontact, and wiring Zapier or Make automations to eliminate manual data entry and close the loop between outreach and CRM.
Spotting underperformance signals early — falling open rates, low reply rates, rising unsubscribes — and running targeted fixes on targeting, cadence, copy, or deliverability setup to turn a campaign around mid-flight.
Knowing when Lemlist is the right tool and when to recommend something else: fully manual ABM for high-value accounts, Outreach for complex enterprise cycles, or Instantly/Smartlead for ultra-high-volume cold email across many domains.
Giving an honest, grounded assessment of Lemlist's AI agent Aria, AI copy generation, Lemcal for meeting scheduling, and the Lemlist Database — compared practically against Instantly, Smartlead, and La Growth Machine.
Final scoring is performed by Claude (Anthropic), which reads back the full transcript and applies this weighted criteria grid.
Ability to describe real workflows in precise detail: campaign setup, sequence configuration, conditional branching, reply handling, and deliverability settings (Lemwarm, DNS records, sending limits, bounce management).
Sophistication in using custom variables, liquid syntax, personalized images and videos, and ability to link those creative choices to measurable outcomes like reply rate and positive reply rate.
Rigor in test design, relevance of chosen metrics, ability to interpret a Lemlist analytics dashboard, and quality of optimization decisions grounded in data rather than gut feel.
Command of native integrations (HubSpot, Pipedrive), enrichment tools (Lemlist Database, Dropcontact, Lusha), and Zapier/Make automations that embed Lemlist into a complete, end-to-end outbound process.
Ability to step back from the tool: identifying when Lemlist is not the right choice, comparing it objectively with competing platforms, and adapting the outreach strategy to the business context.
A Plume session takes about 20 minutes, from tech check to badge delivery.
The AI checks your microphone and connection quality, then walks you through the exam format: 15 minutes, conversational, no notes required. You can reference real or anonymized campaign examples throughout.
You introduce yourself briefly, then walk the AI through your most successful Lemlist campaign: audience, sequence structure, key results, and the decisions that made the difference.
The AI probes 3 to 4 themes from: Lemwarm and deliverability setup, liquid syntax personalization, A/B test design, handling an underperforming campaign, CRM and enrichment integration, the Aria AI agent, and competitive positioning vs Instantly, Smartlead, or La Growth Machine.
The AI presents a concrete situation — a domain starting to hit spam, a reply rate collapse after step 3, or a wave of negative replies — and asks how you'd diagnose and fix it in real time.
Claude Opus analyzes the full transcript and delivers a score from 0 to 100, a Novice/Proficient/Advanced/Expert level, a detailed dimension-by-dimension report, and a shareable badge link ready to post on LinkedIn.
Your score out of 100 translates into a level a recruiter can grasp at a glance.
You've launched basic email sequences on Lemlist, know how to import a CSV list, and can use the default templates — but you haven't touched advanced personalization, haven't configured deliverability settings, and rely mostly on the platform's built-in defaults.
You build multi-step sequences with conditional follow-ups, use custom variables and basic liquid syntax, have set up Lemwarm, and track your open rate and reply rate to iterate on copy. You're effective but still have gaps in deliverability depth and A/B test rigor.
You run full multichannel sequences combining email, LinkedIn steps, and cold calls. You use liquid syntax for personalized images and videos, handle complete DNS configuration, run structured A/B tests, and have integrated Lemlist with your CRM and enrichment tools via Zapier or Make.
You manage complex outbound programs across multiple domains and personas, make informed decisions about when to use Lemlist versus Instantly, Smartlead, or La Growth Machine, have a grounded view of Aria's real-world value, and coach or train others on the platform with precise performance benchmarks.
No degree or years of experience required to take the badge. Here are the profiles it makes the most sense for.
You use Lemlist daily to fill the pipeline and want a credible, verifiable signal on your LinkedIn profile to land a senior role or demonstrate growth to your manager — not just another self-declared skill.
You own the cold outreach strategy for your team and want to benchmark your Lemlist expertise objectively — especially as alternatives like Instantly and Smartlead gain ground and you need to justify your tooling decisions.
You help startups and SMBs with their prospection and want to differentiate your offer with a verifiable credential rather than another bullet point on your LinkedIn profile or agency website.
You're doing your own prospecting and want to make sure your Lemlist practice is solid before delegating it — and credibly demonstrate hands-on go-to-market know-how to potential investors or hires.
You're learning cold outreach and need tangible proof of your Lemlist skills to convince a recruiter you're ready to hit the ground running, despite limited formal sales experience on your resume.
Where and how your Lemlist badge will help you day to day.
You're applying to a scale-up that lists Lemlist experience as a requirement. You add your badge link to your application email. The hiring manager sees your 78/100 Advanced score and skips the technical screening call entirely.
A VP Sales asks you to run their outbound as a contractor. Instead of a generic proposal, you share your Lemlist Expert badge to justify your day rate and demonstrate you can operate without hand-holding on the tooling side.
Your manager is on the fence about giving you ownership of the full outbound program. You take the badge, get a detailed report showing your strengths and gaps, and use it as structured evidence in your next performance review.
You're a Head of Growth hiring an operational SDR for Lemlist. You ask the two finalists to take the badge before making an offer. The scores and dimension reports give you an objective basis to compare two candidates with similar-looking resumes.
You've been using Lemlist for six months and want to know where you actually stand. The post-exam report flags that you're under-using liquid syntax and not structuring A/B tests properly — you know exactly what to work on next.
You add the badge to your LinkedIn Licenses and Certifications section with your score and level. Recruiters and prospects who visit your profile can click through to see the full evaluation — far more convincing than a self-endorsed skill tag.
A few minutes to check you have everything you need.
At the end of your session you don't just get a score — here's everything that awaits you.
Get a precise score from 0 to 100 and a certified Novice/Proficient/Advanced/Expert level reflecting your real Lemlist mastery, evaluated by Claude Opus from your live oral transcript.
Access a structured report breaking down your score across the 5 key criteria: operational mastery, personalization, A/B testing, stack integration, and strategic thinking — so you know exactly where you stand and what to improve.
