the complete deliverability tool that helps you land in the inbox

Here's why you need to use a deliverability booster and monitoring tool:



Think of email deliverability as a shield for your emails. It makes sure your emails get delivered and reach the right people in their inboxes. When you work on your deliverability, email service providers (ESPs) will trust you and are less likely to land your emails in the spam folder.



In the long run, monitoring your deliverability is the only way to follow closely your campaigns performance. You’ll receive insights on your technical setup, email content, sending habits and overall performance and know how to improve every part of your campaign.

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.



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.



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. 



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

It keeps track of your sending volume, warn you if your content triggers spam-filters and keep a steady sending volume to avoid sending bad signals to email providers.




With deliverability monitoring, you’ll receive daily insights about your performance, technical setup and sender reputation. 



Keeping an eye on every part of your deliverability is the best way to avoid bad surprises or blacklists.

Yes! If you want to learn more about deliverability and how lemwarm helps improving it, join us for a deliverability live event every two weeks at 6PM CET.

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.
