Lemlist built its reputation on creative, multichannel outreach — custom images and liquid-syntax merge variables dropped into a template, LinkedIn steps and call tasks alongside email, and a 600M+ contact database with smart filters layered on top. It is a genuinely capable sequence-builder: you design a template once, wire in custom variables, and the platform fills in the blanks per recipient across whichever channels you enable.
Defrost skips the template entirely. There is no merge-variable fill-in-the-blank step — every email is written fresh for that one recipient, grounded in real research about their company. Leads are found for you through live search, scraping, and public registries (not pulled from a shared database) and every address is verified through a multi-provider verification cascade before it reaches a mailbox. Sending goes out through a Defrost-managed relay with per-customer DKIM, automated warmup, and a 3% bounce-rate auto-pause. There is also a done-for-you tier if you would rather hand off the whole campaign; Lemlist has no packaged equivalent.
| Feature | Defrost | Lemlist |
|---|---|---|
| What it fundamentally is | A done-for-you cold outreach pipeline: find leads → verify → write → send. | A multichannel sequence-builder (email, LinkedIn, calls, SMS) built around templates with merge-variable personalization. |
| Email writing | No templates — a fresh, fully AI-written email per recipient, grounded in real research about their company. | Template-based: you build one sequence with liquid syntax and custom text/image variables, and it fills the blanks per contact. |
| Lead sourcing | Independent, live discovery per campaign via search, scraping, and public registries. No shared database. | A 600M+ contact database with smart ICP filters, plus the option to upload and enrich your own CRM/CSV list. |
| Email verification | Every address checked through a multi-provider cascade before sending, included in the pipeline. | Verified emails are a pay-per-success add-on (5 rechargeable credits each), separate from the base plan. |
| Channels | Email only, run through a managed relay built for deliverability. | Email, LinkedIn automation, call dialer, and SMS/WhatsApp on the Multichannel plan. |
| Sending infrastructure | Defrost-managed relay with per-customer DKIM, automated warmup, and a 3% bounce-rate auto-pause. | Send from your own connected mailboxes (5 senders per user on Multichannel) with a deliverability hub and warm-up protection. |
| Pricing model | Flat monthly plans from $79/mo (500 leads, 2 mailboxes) to $1,200/mo (10,000 leads, 40 mailboxes). | Email plan from $69/mo ($55/mo annual); Multichannel from $109/mo ($87/mo annual), priced per user; Enterprise custom for 5+ users. Verified emails, phone numbers, and intent signals billed separately as credits. |
| Trial | No free tier — card charged at checkout, plan active immediately, backed by a 30-day money-back guarantee. | 14-day free trial on the Multichannel plan, no credit card required. |
| Done-for-you option | Yes — a DFY tier where Defrost runs the whole campaign for you. | No packaged done-for-you tier; Enterprise adds a dedicated account manager and 1:1 onboarding, but you still run the campaigns. |
| Who runs it day to day | Anyone — describe your ideal customer once, Defrost handles sourcing, verification, copy, and sending. | Best for teams who want to design creative, multichannel sequences and manage senders, credits, and lead lists themselves. |
Who should choose Defrost
Choose Defrost if you would rather not build a template at all — if you want every email written from scratch for the person receiving it, leads found and verified without touching a database or spending credits, and sending handled on infrastructure built for deliverability. It suits founders, SMBs, and sales teams who want the outcome without assembling a sequence, buying verification credits, and managing sender rotation themselves. Stale or purchased contact data is a real bounce risk regardless of which platform sends it — see our breakdown of why bought lead lists bounce and the fundamentals in our cold email deliverability guide.
Who should choose Lemlist
Choose Lemlist if you want hands-on control over a creative, multichannel sequence — custom variables, liquid syntax, LinkedIn and call steps alongside email — and you are comfortable owning template design, sender management, and lead sourcing (whether from its bundled database or your own list). It is a strong fit for sales teams that want to design the outreach motion themselves across more than just the inbox.

Frequently asked questions
- Is Defrost cheaper than Lemlist?
- Lemlist's Email plan starts at $69/mo ($55/mo annual) and Multichannel at $109/mo ($87/mo annual) per user, with verified emails, phone numbers, and intent signals billed separately as credits. Defrost is a flat plan from $79/mo (500 leads, 2 mailboxes) to $1,200/mo (10,000 leads, 40 mailboxes) that already includes verification and copywriting, with no per-user or per-credit add-ons.
- Does Defrost include a lead database like Lemlist?
- No. Lemlist bundles a 600M+ contact database with smart ICP filters that you search and export from. Defrost has no stored database — every campaign runs a fresh, independent discovery pass through search, scraping, and public registries, with every address verified through a multi-provider cascade before it reaches a mailbox.
- Can I migrate from Lemlist to Defrost?
- There is no template or sequence import — switching means starting your campaigns fresh in Defrost, which independently discovers and verifies leads and writes a fully custom email per recipient rather than filling in a Lemlist template. Any suppression list you already maintain can be brought over as a CSV.
- Does Defrost do multichannel outreach like LinkedIn or calls, the way Lemlist does?
- No — Defrost is email only, sent through a Defrost-managed relay built for deliverability with per-customer DKIM, automated warmup, and a 3% bounce-rate auto-pause. Lemlist's Multichannel plan adds LinkedIn automation, a call dialer, and SMS/WhatsApp alongside email if you need channels beyond the inbox.
