lemlist is an AI outbound platform that runs your whole motion in one place.

The Email plan is volume-based, starting at $69/mo ($55/mo billed yearly) for 50k emails, with unlimited users. Multichannel runs $109/mo ($87/mo billed yearly). Enterprise is custom and annual, with a 5-seat minimum. A 14-day free trial needs no credit card. See the full lemlist pricing plans for tier details.

Teams that live or die by inbox placement and want personalization beyond a first name. If deliverability at volume and intent-based timing drive your pipeline, lemlist fits. It also suits growing teams, since the email plan keeps users unlimited instead of billing each seat.

WhatsApp is a paid add-on with no public price, so budget for it separately. Enrichment and lead pulls run on pay-per-use credits, so cost rises with usage. The 650M+ database from the lemlist lead database is smaller than Reply.io’s 1B+ pool.

Reply.io is an AI-powered sales engagement platform built around channel breadth and automation. It runs conditional, branching sequences across email, LinkedIn, WhatsApp, SMS, and calls, plus any channel through Zapier. Its flagship is Jason AI, an SDR agent that researches prospects and books meetings on your behalf. A built-in “Reply Data” database gives you 1B+ verified B2B contacts without a separate tool.

Teams that want every outreach channel plus an autonomous AI SDR in one platform, and have the budget for per-seat or agent pricing. Agencies also get a white-label dashboard to manage client accounts under their own brand.

Multichannel is per-seat, and LinkedIn and calls are paid add-ons on the email plan, so costs climb as you grow. Jason AI SDR starts at $500/mo. Trustpilot reviewers have flagged Jason AI content quality and contact-data accuracy. Reply.io also has no dynamic image or video personalization.

Here is how the two tools split across the factors that decide most outbound stacks. Each criterion has one winner and one reason. lemlist takes four, Reply.io takes two.

1. Pricing and value: winner is lemlist. lemlist’s email plan scales by send volume with unlimited users, while Reply.io charges per seat for multichannel and bills LinkedIn and calls as add-ons.

2. Ease of use: winner is lemlist. lemlist keeps setup and outreach in one guided workflow, while Reply.io’s channel breadth and branching logic add configuration overhead.

3. Feature depth and channels: winner is Reply.io. Reply.io ships native SMS and WhatsApp steps inside sequences plus a $500+/mo autonomous AI SDR, a wider automation range than lemlist.

4. Data and enrichment: winner is Reply.io. Reply.io’s built-in 1B+ contact database is larger than lemlist’s 650M+ pool.

5. Deliverability: winner is lemlist. lemlist includes lemwarm warm-up on every seat, plus inbox rotation, custom tracking domains, and spam-score checks in its Deliverability Hub.

6. Personalization: winner is lemlist. lemlist offers dynamic image and video personalization at scale, which Reply.io does not match.

The two tools split cleanly along channels versus craft. Match the pick to what moves your pipeline.

Choose lemlist if deliverability, visual personalization, intent triggering, and non-per-seat email pricing lead your decision. You get lemwarm on every seat, dynamic image and video personalization, intent-based campaign triggers, and an email plan that scales by volume instead of headcount. That combination protects inbox placement while you add reps without watching the bill climb per seat.

Choose Reply.io if a built-in 1B+ database, native SMS and WhatsApp steps, and a fully autonomous AI SDR justify per-seat and agent pricing. Reply.io wins on raw channel breadth and data volume in a single platform, and Jason AI can run prospecting with limited hands-on work once you fund it.

For most deliverability-focused sales teams sending personalized outreach at scale, lemlist is the stronger daily driver. If you want every channel plus an autonomous agent under one roof and have the budget, Reply.io earns the look.

lemlist leads on deliverability and dynamic image and video personalization, with volume-based email pricing. Reply.io leads on channel breadth, a 1B+ contact database, and the Jason AI autonomous SDR, priced per seat.

lemlist. Every seat includes lemwarm warm-up, and the Deliverability Hub adds inbox rotation, custom tracking domains, and spam-score checks. Reply.io offers a Deliverability Suite with warm-up via Mailtoaster.ai, but warm-up is not bundled into every seat the same way.

Both do. Reply.io includes native SMS and WhatsApp steps inside sequences (SMS and calls are an add-on on the email plan). lemlist supports WhatsApp and SMS too, though WhatsApp is a paid add-on with no public price.

It depends on seats. Reply.io’s email plan starts lower at $49/mo, but multichannel is $89/user/mo, so cost grows with each seat. lemlist’s email plan starts at $69/mo with unlimited users, which is cheaper once your team grows.

Reply.io, with 1B+ verified contacts in Reply Data. lemlist’s database holds 650M+ leads.

lemlist includes LinkedIn steps in its multichannel workflow without a separate per-account fee. Reply.io supports LinkedIn automation as a $69/mo per-account add-on on the email plan, so the cost depends on how many accounts you run.
