lemwarm is good, we use it for my agency and have a bunch of clients on it. Compared to other tools, I find lemwarm gives you a lot of control to decide how much risk to take with sending, which I like!

What’s the point of cold emails when they don’t land in primary. Using lemwarm for a while and the deliverability of my email account has significantly improved. Thanks to the reports, I could control the number of emails sent and didn’t land in spam.

FAQ

Why use an email warm-up tool?
Here's why you need to use an email warm-up tool:

Think of email warm-up as a shield for your emails. It makes sure your emails get delivered and reach the right people in their inboxes. When you use it, email service providers (ESPs) will trust you more and won’t mark your emails as spam.

Here are 5 ways an email warm-up tool helps you:

1. More emails in the inbox → your emails will land where people actually see them.
2. Higher open & reply rates →  more people will read and reply to your emails when they see them in their inbox.
3. Fewer bounced emails → you'll avoid those annoying delivery failure messages.
4. No blacklisting → your email domain will be safe and won't get a bad reputation with email providers.
5. Beat spam filters → your sending volume will stay consistent, so your emails won't be treated as spam.
What does lemwarm do?
lemwarm is a warm-up and deliverability booster tool.

In simple words, lemwarm helps you send emails without them going to spam. It has one goal: to make sure your emails reach your audience.

Here's how it works:

Step 1: Setup your email correctly

Before you start sending emails, lemwarm helps you set up your email correctly. This means adjusting some settings like SPF, DKIM, DMARC, MX Records, and Custom Tracking Domain.

Step 2: Check your deliverability score

Right at the start, lemwarm assigns you a score out of 100 to show how well your emails are being delivered. The higher the score, the better (ideally it should be > 90). Through lemwarm's process, your score will improve over time.

Step 3: Join a smart cluster

lemwarm creates a custom plan for you based on your industry, target audience, location, and email goals. It then groups you with other users like you in smaller clusters. Interacting with other senders just like you will make your email warm-up look completely natural and improve the deliverability of your real campaigns.

Step 4: Start your email warm-up

Once you turn lemwarm ON, the initial warm-up process starts. With 20,000+ domains from 150+ countries, lemwarm has the most diverse and advanced email warm-up pool on the market.  

Personalized warm-up emails will be sent to your cluster automatically. You'll also receive custom replies to these warm-up emails to make the process as natural as possible. 

The initial warm-up process takes about 3-4 weeks. During this time, you'll also see your deliverability score improve as Increasing your sending volume gradually will reduce your chances of landing in spam.

Step 5: Boost your deliverability

After the warm-up phase, lemwarm focuses on maintaining and boosting your deliverability.

It keeps track of your sending volume, monitors your deliverability score, checks for blacklists, and ensures your technical settings are correct. It also alerts you in case of any issues.

By following these steps and using lemwarm, you can avoid spam and land emails in your audience's inboxes.
Who can use lemwarm?
lemwarm can be used by anyone sending emails.

A low email deliverability will land your emails in spam and ruin your campaign results no matter what kind of emails you send. So if you are:

• an entrepreneur reaching out to potential clients, investors, or leads to grow your business
• a salesperson sending campaigns to prospects to book meetings and close deals
• a marketer sending newsletters to stay top of the mind of an audience
• a company using email for internal communications or transactional email
• or anyone sending emails to reach their audience,

... lemwarm is for you!
When should I use lemwarm?
You should use lemwarm before, during and after sending emails.

Ideally, you should start using lemwarm 3-4 weeks before you plan to start sending campaigns. This gives you time to complete the initial warm-up process.

The warm-up stage gradually increases your sending volume, making it appear completely natural to email providers. This makes your emails bypass the spam filters and land where they belong - in your audience's inbox.

After the initial warm-up phase, ensure you keep lemwarm ON.  At this stage, lemwarm maintains and boosts your deliverability. It keeps track of your sending volume, monitors your deliverability score, checks for blacklists, and ensures your technical settings are correct. It also alerts you in case of any deliverability issues.
How do I check my deliverability score?
lemwarm assigns you a deliverability score out of 100. This score reflects whether your emails are landing in spam or your audience's inbox.

You can check your deliverability score at all times on your lemwarm dashboard 👇
What is good email deliverability?
Good email deliverability means that your emails are successfully reaching your audiences' inboxes and not being marked as spam.

Here are some metrics you can use to track your deliverability :

• Deliverability score is > 90
Bounce rates < 5%
• Open rates > 45%* (cold emails)
• Spam complaint rates < 0.08%

How long should I use lemwarm for?
The initial warm-up phase takes around 3-4 weeks. But stopping the warm-up process after this stage will make your sending pattern irregular, which can reduce your deliverability score and land emails in spam.

For long-term results, it's essential to keep your warm-up and deliverability booster tool ON before-during-after sending campaigns.

Yes, lemwarm is 100% reliable and safe to use. It works on an IMAP-based system and follows all email provider rules.
