This calculator prices lemlist's Email plan by monthly send volume (leads x emails per lead). Multichannel at $109/user/mo is out of scope here - it is the better lemlist fit when you need LinkedIn, calling, or WhatsApp. Lead finder credits assume 5 credits per lead at $0.01; list verification is 1 credit per lead. Inbox line uses the cheapest SMTP rate ($5/mo); Google/Outlook start at $10/mo. Domain list price is not published, so we use a $15/yr market-rate assumption.
What lemlist is
lemlist is a sales engagement platform built around creative cold outreach. Teams use it for email sequences with liquid syntax, images, and custom landing experiences, and can step up to Multichannel for LinkedIn, calling, and WhatsApp on a per-user plan. The Email plan is billed by monthly send volume (50k through 1M emails) with unlimited users on the account. Lead finding and verification run on credits ($0.01 each); paid Email plans include lemwarm Essential, and lemlist sells sending domains and inboxes as a bundled purchase.
When they are the right call: Choose lemlist when creative multichannel is the product: image-rich emails, liquid personalization, LinkedIn and calling in one sequencer, and a team that wants campaign craft over an all-in-one lead database and infrastructure bundle. Multichannel at $109/user/mo is the natural home for that stack (priced outside this Email-plan calculator).
Where Ken fits
Choose Ken when cold email is the channel and you want leads, verification, AI qualification and personalization, domains, inboxes, warmup, and placement monitoring in one volume-based plan - without assembling credits, mailbox subscriptions, and finder packs separately.
The honest tradeoffs.
lemlist
Strengths
- Creative email tooling: liquid syntax, images, and highly customizable sequences that many sales teams still prefer for brand-forward outreach.
- Real multichannel path (LinkedIn, calls, WhatsApp add-on) on Multichannel and Enterprise - not email-only.
- Clear Email volume ladder with monthly, quarterly (10% off), and annual (20% off) prices published for each cap.
- lemwarm Essential included on paid plans, plus a Deliverability Hub for monitoring.
Tradeoffs
- Current Email plan includes 0 free finder credits - every found email is 5 credits ($0.05) on top of the platform fee.
- Sending domains and inboxes are purchased separately (SMTP from $5/mo; Google/Outlook from $10/mo); domain list price is not public.
- Email-tier AI personalization is not at the depth of a Clay-style enrichment + LLM workflow; heavy AI work is DIY or another tool.
Ken AI
Strengths
- 300M+ lead database, verification, and AI qualification/segmentation/personalization included in the plan price.
- Domains and inboxes sized to your volume are included - no separate mailbox subscription line.
- Warmup and placement tests included; pricing scales by leads with quarterly and annual discounts.
Tradeoffs
- Email-first product: no built-in LinkedIn, calling, or WhatsApp sequencer like lemlist Multichannel.
