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 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

Check which lemlist plan you have. With Email Pro ($69/month) or Multichannel Expert ($99/month) plans, each user gets access to lemwarm (Essential) included in the bundle.

Why this matters: Understanding your benefits ensures you're maximising the value of your subscription and not paying for features you already have access to.

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.

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

In lemlist, open your workspace Billing page and find the lemwarm card. and seats for that workspace.

Navigate to the "Plans & Billing" section

Click Manage plan to view and manage your lemwarm subscription

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.

Phase 3: Configure Your Warm-up Settings

Step 7: Complete technical setup verification

Before starting warm-up, complete your email authentication setup including SPF, DKIM, DMARC, MX records, and Custom Tracking Domain.

Use lemwarm's technical setup checker to verify all settings are properly configured.

Step 8: Set warm-up parameters

Configure your warm-up settings based on your email account age:

For accounts less than 6 months old:

Warm-up limit: 30 emails/day
Ramp-up increment: 1 email/day

For accounts older than 6 months:

Warm-up limit: 40 emails/day
Ramp-up increment: 2 emails/day

Why these settings: Gradual increases prevent triggering spam filters while building reputation steadily.

Step 9: Start the warm-up process

In lemwarm, go to your Deliverability score dashboard and click Start lemwarm to begin sending and receiving warm-up emails.

lemwarm will automatically:

Send emails to its warm-up network
Simulate human-like email interactions
Help pull emails out of spam (when possible)
Build your sender reputation gradually

Phase 4: Monitor and Optimize

Step 10: Track your deliverability score

Monitor key metrics in your lemwarm deliverability dashboard:

Deliverability score (aim for 90+)
Emails landed in spam
Blacklist signals
Status insights and recommendations

Keep lemwarm always active. If leads mark your campaigns as spam, it can be reflected in results, helping you identify issues with content or sending patterns.

Step 11: Consider upgrading to Smart plan (optional)

If you need advanced features, you can upgrade to lemwarm Smart (pricing depends on your workspace and billing period).

Smart plan benefits include:

Personalized warm-up emails
Industry-specific clusters
Custom deliverability alerts
Real email template warm-up

Decision point: Upgrade if you're sending to specific industries or need to warm up actual campaign templates.

Practical Application / Real-Life Example

Example: B2B Sales Team Implementation

Sarah's team at TechStartup Inc. implemented the lemlist–lemwarm bundle:

Setup: 5 sales reps, each with Email Pro plan ($69/month)
Savings: Each rep uses the included lemwarm access rather than buying a separate warm-up tool
Configuration:
- Each rep connected 3 email addresses
- 30-day gradual warm-up for new domains
- Maintained a 95+ deliverability score
Results:
- Reply rates increased from 8% to 23%
- Zero spam complaints after 3 months

Try It Yourself Checklist:

Verify your lemlist plan includes lemwarm
Log into lemwarm with the same email as lemlist
Assign lemwarm seats to the right users in Billing
Complete technical setup before starting campaigns
Set conservative warm-up limits initially
Monitor results daily for the first 2 weeks
Keep warm-up active even during campaigns

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 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.
