TL;DR: Compare lemwarm’s Essential vs Smart plan so you can pick the right warm-up features for your inbox. This helps you improve deliverability with the right level of personalization and guidance. Takes about 3 minutes.
Who Should Use This
You’re choosing between Essential and Smart and want to understand what you get with each plan.
You want to improve deliverability and you’re not sure whether you need Smart cluster and Smart content email.
If you only need basic warm-up insights (DNS + deliverability status), start with Essential. If you want personalized warm-up behavior based on your audience and goals, choose Smart.
Why This Matters
Picking the right plan helps you warm up your inbox safely and build a strong sending reputation before launching outbound campaigns. The Essential plan covers the fundamentals (DNS + deliverability visibility), while Smart adds personalization and cluster-based warm-up for a more tailored approach.
Key Concept / Mental Model
Essential = core warm-up features + checks to help you spot deliverability risks.
Smart = everything in Essential, plus a questionnaire-driven setup that adapts warm-up content and cluster to your context.
If you want more customized warm-up emails (including custom variables), Smart is the better fit.
Step-by-Step Guide
1. Compare the Essential and Smart plans
Review the plan comparison to see pricing and which features are included in each plan.
2. Understand what’s included in the Essential plan
Essential includes:
Essential content email
DNS check
Deliverability score
3. Essential content email (what it means)
If you used lemwarm in the past, you might remember the older “funny” warm-up email content. That’s no longer the case—lemwarm now uses real-life templates that make more sense.
If you want warm-up emails that are even more customized (including custom variables), check the Smart plan section below.
4. DNS check (what it means)
The DNS check dashboard helps you see whether your DNS setup looks healthy or if records should be created/updated. To view the latest results, go to DNS checks and click Refresh checks.
In the details panel, you can review checks such as MX exchanges, SPF record syntax, DMARC record, your email test results, and your SpamAssassin score.
To learn more about DNS records, see: How to set up your DKIM, SPF and DMARC.
5. Deliverability score (what it means)
The Deliverability score analyzes your inbox setup and lemwarm usage to estimate your deliverability status.
Red: don’t start campaigns yet. This usually means something is wrong (for example: DNS issues, configuration problems, or other deliverability risks). You’ll see guidance on how to improve.
Orange: you can start campaigns, but keep volume low while results are still improving.
Green: you can start campaigns. Keep lemwarm active to maintain strong deliverability results.
6. Understand what’s included in the Smart plan
With the Smart plan, you go through a questionnaire. Based on your answers, lemwarm adapts the warm-up content and the cluster you’re placed in.
Smart includes:
All features included in the Essential plan
Smart cluster
Smart content email
7. Smart cluster (what it means)
You’ll be automatically assigned to a cluster based on your industry, target audience, and email goals. This helps tailor the warm-up strategy to boost your deliverability score.
8. Smart content email (what it means)
lemwarm sends automated, ultra-personalized warm-up emails from your inbox based on your audience and email goals. It can also use custom variables based on what you answered in the Smart questionnaire.
This helps improve your sending reputation and reach/maintain a strong deliverability score.
Troubleshooting / Pitfalls
Issue: You’re not sure which plan to choose.
Root cause: It’s unclear whether you need basic warm-up features or a more tailored approach.
Fix:
Choose Essential if you mainly want DNS checks + deliverability visibility.
Choose Smart if you want a questionnaire-driven setup with Smart cluster and more personalized warm-up content (including custom variables).
Can I add more email addresses to warm in a single plan?
It depends on which subscription you have:
lemwarm-only subscription: This works as 1 account = 1 email address = 1 subscription. If you want to warm another email address, you’ll need another lemwarm subscription.
lemlist + lemwarm bundle: You can warm multiple email addresses under the same bundle, based on your lemlist plan limits:
Email Pro: up to 3 email addresses
Multichannel Expert: up to 5 email addresses
So the “1 seat = 1 email address” rule only applies in bundled setups where multiple inboxes are supported by your lemlist plan.
