Learning Objective
By the end of this tutorial, you'll know how to access your included lemwarm plan, assign lemwarm seats to teammates, configure warm-up safely, and monitor deliverability results.
Why This Matters
Combining lemlist with lemwarm creates a powerful outreach system that helps keep your emails out of spam folders by building sender reputation through automated warm-up processes. The warm-up process typically takes 3–5 weeks and helps you consistently land in the primary inbox. With proper setup, users typically see deliverability scores above 90%, leading to 2–3x higher reply rates on their outreach campaigns.
Prerequisites
Before starting this tutorial, you should already have:
An active lemlist paid plan (Email Pro, Multichannel Expert, or Enterprise. The bundle is not available with a free trial)
Access to your lemlist account dashboard
Your email provider is connected to lemlist (see Getting Started: Connect Your Email Provider)
Basic understanding of email authentication (SPF, DKIM, DMARC) — see Getting Started: Technical Setup Guide
Core Lesson: Step-by-Step Workflow
Phase 1: Understand Your Bundle Benefits
Step 1: Review your plan's lemwarm benefits (and pricing rules)
Check which lemlist plan you have. With Email Pro or Multichannel Expert plans, each user gets access to lemwarm (Essential) included in the bundle.
Existing customers (already subscribed before the change):
Email Pro: $69/month
Multichannel Expert: $99/month
You can still increase or decrease your seat count on your current plan at your existing pricing.
If you change plan (e.g., Email Pro → Multichannel Expert), or if you cancel (churn) and later renew, you’ll move to the new prices.
New customers (after February 5th):
Email Pro: $79/month
Multichannel Expert: $109/month
Prorated Billing: If upgrading from a Lemwarm-only plan to a paid Lemlist plan, Lemwarm Essential will be included, and recent Lemwarm charges will be prorated as a discount on your next invoice. Similarly, if you opt for higher plans, such as Email Pro, the prorated value of your existing Lemwarm subscription is applied to future invoices.
Why this matters: Understanding your benefits and pricing rules ensures you're maximising the value of your subscription and avoiding surprises when changing plans or renewing.
Step 2: Check email address limits
The Email Pro plan allows up to 3 email addresses per user, while Multichannel Expert provides up to 5 email addresses. All connected addresses under one user can use the same lemwarm access (based on the seats assigned to that user).
Tip: If you manage multiple email addresses for different campaigns, keep them under the same lemlist user so warm-up management stays centralized. Also, make sure to comply with lemlist Terms when it comes to connecting multiple emails to one account
Phase 2: Access lemwarm and Confirm Your Included Plan
Step 3: Log in to lemwarm using your lemlist email
Go to app.lemwarm.com and log in using the same email address you use for lemlist (SSO or email/password). Use your existing lemlist email. Do not create a separate account with a different address, or the bundle may not be recognized. For better synchronization and improved tracking of emails, it is recommended to use OAuth instead of SMTP/IMAP connections, particularly for Gmail and Microsoft email accounts.
Step 4: (Alternative access) Open lemwarm from the product switcher in lemlist
In lemlist, open the product switcher from the top-left (lemlist dropdown), then select lemwarm.
Step 5: Activate the Essential plan
Note: Lemwarm Essential may appear as $29/month but will show as $0 if your paid Lemlist plan is active.
In lemlist, open your workspace Billing page and find the lemwarm card. and seats for that workspace.
Navigate to the "Plans & Billing" section
2. Click Manage plan to view and manage your lemwarm subscription
3. Select the lemwarm Essential Plan - it will show as $0 for lemlist subscribers
Why this step: Manual activation is required in the "Plans & Billing" section to enable lemwarm features - it's not automatic.
Step 6: Assign lemwarm seats to team members
From the same lemlist Billing page, use the lemwarm seat toggle on each user to activate or remove access. If a user does not have a lemwarm seat yet, click the toggle to activate it (it will show as $0.00 for eligible lemlist bundles). If you turn the toggle off later, the user will no longer have access to lemwarm features.
Troubleshooting & Pitfalls
Issue: Can't access the included lemwarm plan
Root cause: Using a different email for lemwarm than your lemlist account, or no seat assigned to your user
Fix:
Log out of lemwarm
Log back in using the same email address associated with your lemlist user
In lemlist Billing, confirm your user has an active lemwarm seat toggle
Verify you have an eligible lemlist plan (not free trial or Email Starter)
Issue: lemwarm not warming up multiple addresses
Root cause: Email addresses are connected under different lemlist users (and seats are not assigned as expected)
Fix:
Consolidate email addresses under the intended lemlist user (when appropriate)
Ensure that user has a lemwarm seat enabled in lemlist Billing
Issue: Deliverability score dropping
Root cause: Scaling cold sending too aggressively during warm-up, poor targeting, or spam-triggering content
Fix:
Reduce cold email volume while reputation is still building
Wait the full 3–5 weeks before scaling
Review content and sending patterns for spam triggers
Issue: Team member can't access lemwarm
Root cause: The user is set as a guest seat (or not assigned a seat) in lemlist Billing
Fix:
Admin: enable the lemwarm seat toggle for that user in lemlist Billing
User: log into lemwarm using their lemlist email
Confirm the invite is accepted if the user is still “Pending invitation”
Issue: I’m seeing different prices than a teammate / than what’s listed in this article
Root cause: Your workspace may be on existing customer (legacy) pricing or new customer pricing after the planned early-February change.
How pricing applies:
Existing customers keep their prices when adjusting seat count.
Switching to a different plan or canceling and renewing applies the new prices (+$10 per plan).
Issue: I'm receiving a lot of “spam” emails since I started lemwarm
Root cause: If those emails have lemwarmup in the subject line, they’re not spam. Those are lemwarm warm-up emails. lemwarm sends warm-up emails to other lemwarm users, and you’ll also receive warm-up emails from other lemwarm users (then lemwarm replies to them).
Fix:
Create a filter/rule in your mailbox for emails with lemwarmup in the subject line.
Set the rule to: Skip Inbox (Archive), Never send to spam, and Mark as important (so your mailbox stays clean without harming warm-up).
Do not delete, forward, move to a folder, or reply to these emails manually. It can interfere with lemwarm’s warm-up behavior. Additionally, ensure your Gmail filters are properly set up:
Check for labeling conflicts under Gmail Settings > Filters.
When creating filters, select 'Also apply filter to matching conversations' to include existing emails. If Lemwarm emails are not appearing in your Sent folder, consider the type of mailbox connection you are using:
SMTP/IMAP connections: Lemwarm emails sent via SMTP/IMAP do not appear in the Sent folder as these protocols don't allow Lemlist to store emails in your mailbox.
OAuth connections: OAuth is recommended for improved synchronization and visibility of Lemwarm emails, especially for Gmail and Microsoft accounts.
