Performance Showdown: 1,104 Lead Campaign Test Between lemlist and Instantly
Campaign Performance & Success Rates
The 1,104-lead campaign test revealed a massive performance gap between lemlist and Instantly.ai, not just in numbers, but in how each platform handles cold outreach at scale.
Instantly.ai achieved a 77% open rate and 4.4% reply rate, significantly outperforming lemlist, which landed at 36.5% open rate and 0.9% replies under identical campaign conditions.
Now let’s take a look at features.
Campaign Process and Management
lemlist Setup
From the main dashboard, you can create a new campaign in a few clicks. The workflow is guided but modular, ideal for teams that want both automation and control.
Here’s how the setup unfolds:
1. Campaign Creation
From the Campaigns tab, you start by naming your campaign and selecting your preferred setup method, AI-generated or manual.
2. AI vs. Manual Setup
AI Campaigns use the built-in AI Sequence Generator, which can build ready-to-launch, multichannel campaigns in minutes based on your audience, tone, and goals.
Manual Campaigns give you granular control: add emails, LinkedIn messages, voice notes, or even calls, all customizable step by step.
3. Building the Sequence
The sequence builder lets you visually design your outreach path. You can drag and drop steps like:
- Automatic email sends
- LinkedIn actions (connect, message, visit)
- Voice messages (AI-assisted)
- Tasks or API calls for manual touchpoints
4. Content Setup
Each email block supports {{variables}} and AI-enhanced personalization, letting you refine tone, length, and structure before launch. You can mark steps as manual or automated depending on your strategy.
5. Launch
Once the sequence is ready, lemlist connects it to your sender account and prepares the campaign for live sending. You can monitor performance from the dashboard — open rates, reply rates, and task completion.
Instantly Setup
Setting up a campaign in Instantly.ai is built for speed — every step is streamlined for quick launch and scale.
1. Add Leads
Instantly gives four options to import contacts:
- Upload a CSV
- Pull directly from Lead Finder
- Add emails manually
- Or connect Google Sheets for dynamic syncing
Each source integrates seamlessly into the campaign, making it easy to test or refresh lead lists without breaking workflows.
2. Build the Sequence
The sequence editor is straightforward and text-first.
Users can add multiple steps, variants, and delays (e.g., send next message after 2 days).
Dynamic fields like {{firstName}}, {{companyName}}, and {{jobTitle}} personalize each message.
AI tools assist with phrasing and personalization at scale, ensuring copy remains natural across large sends.
3. Set Schedule & Rules
Scheduling is flexible — choose a timezone, set send windows (e.g., 9:00 AM–6:30 PM), and select active days.
You can save multiple schedules, making it simple to target different regions without duplicating campaigns.
4. Launch & Monitor
Once live, campaigns appear on the dashboard with progress stats: sent, opened, clicked, and replied.
The interface updates in real time and allows pausing or editing without interrupting delivery.
AI Powered personalization
Lemlist
lemlist integrates AI directly into the campaign editor, allowing users to optimize every email for specific outcomes without leaving the sequence builder.
The “Boost Your Impact” panel provides focused AI actions for key goals:
- Boost email deliverability – Adjusts phrasing, structure, and link placement to reduce spam triggers.
- Increase reply rate – Rewrites intros and CTAs for conversational tone and relevance.
- Improve meeting booking rate – Refines closing lines and call-to-action phrasing.
- Improve open rate – Suggests subject line variations optimized for engagement.
- Make emails more persuasive – Reframes messaging to highlight value and credibility.
Each AI action runs in one click, generating optimized alternatives that users can review or edit before applying.
Personalization layers can also be added dynamically through variables and AI-generated snippets (like custom icebreakers or data-based intros), keeping outreach scalable but human-sounding.
Instantly
Instantly integrates multiple AI tools directly in the sequence editor to speed up copy creation and improve personalization across campaigns.
- AI Sequence Writer – Generates complete email sequences based on campaign context. It automatically adjusts tone, structure, and flow for cold outreach.
- AI Sentence Writer – Helps refine single sentences or paragraphs to sound more natural and personalized.
- AI Spam Words Checker – Scans drafts and flags potential spam triggers before launch, improving inbox placement.
Users can apply these tools inline while writing — no switching tabs or prompts. Dynamic variables like {{firstName}}, {{companyName}}, and {{jobTitle}} make every message personal without manual rewriting.
Additionally, built-in email templates (like “Getting Customers for a Lead Gen Agency”) give users a tested starting point that can be fine-tuned with AI for tone and relevance.
Warm up & Deliverability
Lemlist
Deliverability is one of lemlist’s strongest focus areas, and it’s tightly integrated into its ecosystem through Lemwarm, the platform’s native warm-up solution.
Lemwarm simulates natural email behavior by automatically sending and engaging with real inboxes across a private network of verified accounts. It adjusts sending volume gradually, interacts with sent emails (opens, replies, archives), and removes them from spam folders to improve domain reputation.
Key aspects of lemlist’s deliverability setup include:
- Automatic SPF, DKIM, and DMARC checks before launch.
- Real-time deliverability scoring and spam flag detection.
- Domain rotation and activity pacing to reduce sudden spikes in send volume.
This combination helps maintain stable inbox placement even under stricter Google and Yahoo sender policies introduced in 2024.
However, unlike some competitors that include warm-up in all plans, Lemwarm is a separate paid add-on. Users need to subscribe to Lemwarm to access the automated warm-up feature — it’s not bundled into the free or base lemlist tiers.
Instantly
Deliverability is built directly into Instantly.ai’s core system — every email account automatically connects to a native warm-up network.
The warm-up dashboard gives a real-time view of deliverability performance:
- Percentage of emails landing in the primary inbox.
- Number of warm-up emails sent, received, and saved from spam.
- Day-by-day graphs showing send volume and inbox placement.
Users can enable or disable warm-up per inbox with one click. The system uses multi-tier warm-up pools (Basic, Standard, and Premium) to adjust engagement intensity, mimicking authentic sender behavior — opening, replying, archiving, and marking messages as important.
Instantly also supports server and IP rotation for high-volume senders, helping maintain a strong sender reputation across multiple domains.
Value for Money
Lemlist Pricing
lemlist’s pricing reflects its focus on personalization and multichannel control. The plans scale with feature depth, from solo users to full outreach teams.

Multichannel Expert | ~$79 | Adds LinkedIn + call steps, AI sequence generator, and advanced workflows for multichannel campaigns. |

Notes:
- lemlist occasionally offers discounts on annual billing (10–20%).
- Pricing varies slightly by region (USD/EUR).
- Lemwarm, the warm-up feature, isn’t included by default — it’s sold as a separate paid add-on even for paid users.
Instantly Pricing
Instantly.ai’s pricing is built around scale, volume, and simplicity, with a flat-fee model that supports unlimited email accounts and warm-up from the get-go. Here’s a breakdown of what you’ll pay and what you get.
Plan | Monthly Price (USD)* | Key Features |
Growth Outreach | $37 / mo | Unlimited email accounts & warm-up, up to ~1,000 uploaded contacts, ~5,000 emails/month. |
Hypergrowth Outreach | ~$97 / mo | Unlimited accounts & warm-up, up to ~25,000 contacts / ~100,000 emails/month plus full Unibox & A/B testing. |
Light Speed | ~$358 / mo | High-volume tier (~100,000 contacts / ~500,000 emails/month), includes dedicated IP/sharding (SISR). |
Add-Ons | From ~$47 / mo+ | Lead generation (SuperSearch credits), CRM module, extra upload/contact limits. |
Prices reflect monthly billing; annual billing typically offers ~10–20% discount.
What this pricing model means
- Unlimited inboxes & warm-up included in every Outreach plan — no extra per-seat cost as you grow.
- The core plan limits (contacts/emails) are relatively modest unless you upgrade.
- If you add lead-data, CRM, and high-volume sends, your total cost may rise significantly, effectively well beyond the advertised base price.
If neither tool fully matches your workflow or budget, here are some solid alternatives worth considering.
