Instantly and Lemlist solve two different problems. Instantly is a pure cold email sending platform engineered for high volume and deliverability — multiple inbox rotation, built-in warm-up, and a simple sequence builder. Lemlist is a multichannel sales engagement platform that combines email and LinkedIn outreach with a 600M+ B2B lead database, built-in prospecting tools, and in-app calling. If you need to send 10,000+ emails per day and don't care about LinkedIn or lead sourcing, Instantly wins on economics and deliverability. If you need multichannel outreach with built-in prospecting, email verification, warm-up, LinkedIn automation, and calling all in one place, Lemlist is the more complete platform. This comparison uses verified pricing and feature data pulled directly from instantly.ai and lemlist.com in April 2026.
What Is Instantly?
Instantly is an email-first cold outreach platform built for high-volume sending. It started as an email warm-up tool and expanded into a full cold email stack: multichannel warm-up, unlimited sending mailboxes, a unified inbox, and a simple drag-and-drop sequence builder. Instantly's core strength is deliverability at scale. The platform uses an ISP-optimized sending infrastructure, rotating sender accounts to stay under rate limits and maintain inbox placement.
Instantly's lead finding is handled through Instantly Leads, a built-in B2B lead database integrated directly into the platform. You can search by filters like industry, company size, location, and job title, then export verified emails to your campaigns without leaving the app. Instantly also offers an AI writer that personalizes email sequences using prospect data, though it is limited to email copy rather than full content generation.
Instantly does not support any channel other than email. No LinkedIn automation. No WhatsApp. No Instagram. No SMS. It is an email machine, and it is very good at that one job.
What Is Lemlist?
Lemlist is a multichannel outbound sales engagement platform and part of the broader "lempire" product family. It combines a 600M+ B2B lead database, email finding and verification, LinkedIn automation, email warm-up (lemwarm), and multichannel sequences into one platform built for sales teams and SDRs.
Lemlist's core strengths are email deliverability and prospecting. Every plan includes lemwarm for inbox warm-up, an inbox rotation system, and a deliverability hub to monitor sender reputation. Their LinkedIn automation covers profile visits, follows, connection invites, text messages, and even AI-generated voice messages — a feature you will not find in most competitors.
Lemlist also supports in-app calling with VoIP integrations, WhatsApp as a paid add-on, and intent signals for timing outreach based on website visits, hiring, fundraising, and job changes. For teams that need more than email, Lemlist is a fuller suite than Instantly.

Pricing Comparison
Instantly and Lemlist use different pricing models. Instantly charges based on the number of active leads in your account (the prospects you are actively sequencing). Lemlist charges per user per month with tiered plans and paid add-ons.
Instantly Pricing
| Plan | Monthly | Active Leads | Senders | Email Accounts |
|---|---|---|---|---|
| Growth | $30/mo | 1,000 | 1 | Unlimited |
| Hypergrowth | $74/mo | 10,000 | 2 | Unlimited |
| Scale | $149/mo | 25,000 | 5 | Unlimited |
| Enterprise | Custom | Custom | Custom | Unlimited |
Custom email senders for higher volume: extra $15/sender/mo on lower plans. Instantly Leads (database access) is an add-on starting at $27/mo for 500 credits (unverified contacts). 1,000 verified contacts cost $45 extra.
Lemlist Pricing
| Plan | Monthly | Annual (per mo) | What You Get |
|---|---|---|---|
| Email Pro | 79 EUR/user | 63 EUR/user | 3 email senders/user, 200 enrichment credits/mo, lemwarm |
| Multichannel Expert | 109 EUR/user | 87 EUR/user | 5 email senders/user, 400 enrichment credits/mo, LinkedIn + WhatsApp (add-on) |

Add-ons: WhatsApp +20 EUR/user/mo, extra email sender +9 EUR/email/mo, extra deliverability boost +20 EUR/user/mo, additional phone number +15 EUR/number/mo, enrichment overages 1,000 credits = 10 EUR.
Volume scenario comparison
Solo sender, 10,000 emails/month: Instantly Hypergrowth ($74/mo + $27/mo for Leads add-on = $101/mo) vs Lemlist Email Pro (63 EUR/mo annual ≈ $69/mo). Lemlist is slightly cheaper but includes fewer senders (3 vs unlimited on Instantly Hypergrowth).
3-person team, 30,000 emails/month: Instantly Scale ($149/mo + $27/mo Leads = $176/mo) vs Lemlist Email Pro (63 EUR x 3 = 189 EUR/mo ≈ $207/mo annual). Instantly is cheaper at scale for email-only teams.
3-person team needing LinkedIn + email: Instantly does not support LinkedIn, so Lemlist Multichannel Expert (87 EUR x 3 = 261 EUR/mo annual ≈ $287/mo) is the only option here. Instantly forces you to add a separate LinkedIn tool, increasing stack cost.
What Instantly Does Better
Instantly has clear advantages in email-specific areas:
- Unlimited email accounts on all plans — Even the $30/mo Growth plan lets you connect unlimited sending mailboxes. Lemlist limits senders per user (3 on Email Pro, 5 on Multichannel Expert), and charges extra for additional senders.
- A/B testing at the sequence level — Instantly includes native A/B testing for subject lines, body copy, and sending times. Lemlist has A/B testing but it is more limited compared to Instantly's built-in testing framework.
- Cheaper at scale for email-only — For teams sending high volumes of email without needing LinkedIn, WhatsApp, or calling, Instantly's pricing flattens at $149/mo (Scale plan) regardless of email volume. Lemlist scales per seat and per add-on.
- Simpler interface for high-volume email — Instantly is built for one thing: sending a lot of cold email. The interface is streamlined for that task with fewer distractions. Lemlist has more features and a steeper learning curve.
What Lemlist Does Better
- 600M+ B2B lead database — Lemlist's built-in database dwarfs Instantly Leads. Combined with account-based prospecting, email finding and verification using a multi-provider waterfall, and phone number discovery, Lemlist eliminates the need for a separate prospecting tool.
- Multichannel outreach — Email + LinkedIn + WhatsApp + Phone calling in one platform. Instantly is email-only. If you want LinkedIn automation alongside email, Lemlist has it natively. If you need WhatsApp or calling, those are available (WhatsApp as add-on, calling included).
- LinkedIn voice messages — Lemlist supports LinkedIn voice messages and AI-generated voice messages. This is a unique feature that can significantly boost reply rates on LinkedIn, and Instantly has no equivalent.
- Intent signals — Website visits, hiring activity, job changes, and fundraising signals help you time outreach for maximum relevance. Instantly does not have intent signal tracking.
- 40+ native integrations — Lemlist integrates with HubSpot, Salesforce, Pipedrive, Aircall, Ringover, Clay, Apollo, n8n, Make, and dozens more. Instantly's integration ecosystem is smaller.
- In-app calling — A built-in dialer with VoIP integrations lets your team call prospects without switching tools. Instantly has no calling feature.
Who Should Choose Instantly
Instantly is the right choice if:
- Your outreach strategy is 100% email — you do not need LinkedIn automation, WhatsApp, calling, or any other channel
- You need high email volume at the lowest possible cost — sending 10,000+ emails per month with unlimited mailboxes
- Deliverability at scale is your primary concern — Instantly's ISP-optimized routing and multichannel warm-up are purpose-built for this
- You want built-in A/B testing for subject lines and copy without relying on a separate integration
- You run a solo operation or small team focused purely on email outbound — the Growth plan at $30/mo is hard to beat for entry-level volume
Who Should Choose Lemlist
Lemlist is the right choice if:
- You need multichannel outreach — email + LinkedIn automation + WhatsApp + calling in one platform
- You want a built-in B2B lead database with 600M+ contacts, email finding, and phone number discovery — all without leaving the platform
- Email deliverability is a top priority and you want lemwarm, inbox rotation, and a full deliverability hub included
- You already use a CRM like HubSpot or Salesforce and want native two-way sync rather than a built-in CRM
- Your team needs in-app calling with VoIP integrations for phone outreach
- You want intent signals (hiring, fundraising, job changes) to time your outreach automatically
- You are a sales team of 1-3 people where per-seat pricing is still manageable
Frequently Asked Questions
Can Instantly and Lemlist be used together?
Yes. Some teams use Instantly for high-volume email sending and Lemlist for LinkedIn automation and prospecting. But this adds cost, complexity, and data fragmentation. Most teams that need both channels eventually consolidate into a single multichannel platform.
Which tool has better email deliverability?
Both are excellent. Instantly's edge is at extremely high volumes (10,000+ sends/day) where its ISP-optimized routing and unlimited mailboxes shine. Lemlist's advantage is the deliverability hub with monitoring, warm-up, and inbox rotation — all included on every plan. In our experience, both platforms achieve 80%+ inbox placement when properly configured with warm-up, good list hygiene, and engagement-aware sending patterns.
Does Instantly have a lead database?
Yes — Instantly Leads is a built-in B2B lead database with approximately 50M+ contacts. It is an add-on starting at $27/mo for 500 credits (unverified contacts). It is smaller than Lemlist's 600M+ database but sufficient for many use cases.
Does Lemlist have A/B testing?
Yes, Lemlist supports A/B testing for email subject lines and body copy, but it is less sophisticated than Instantly's native A/B testing framework which allows multivariate testing across subject lines, body copy, and sending times.
Which is better for a solo founder?
It depends on your channel needs. If you only send email, Instantly's Growth plan at $30/mo is more affordable than Lemlist's Email Pro at 63 EUR/mo (annual). If you need LinkedIn outreach alongside email, Lemlist Multichannel Expert at 87 EUR/mo (annual) eliminates the need for a separate LinkedIn automation tool.
Does either platform offer a free trial?
Instantly offers a 7-day free trial on all plans. Lemlist does not publicly advertise a free trial, but they offer a 14-day money-back guarantee on annual plans.
