lemwarm offers two plans:

Next, connect the email address you want to warm up. This address can be different from the one you used to create your lemwarm account. You can easily connect your email provider by following this guide.

To adjust lemwarm numbers, you should navigate to the Warmup section on the left side of the dashboard. From there, you can configure the values for you and rest of your teammates.

Now, you are wandering what do those number means. Let's jump to the explanation

➡️ Warm up (number of warm-up email/day after ramp-up)

This is the maximum number of emails lemwarm will send each day after the warm-up process is complete. Once this limit is reached, no more emails will be sent for that day.

➡️ Ramp-Up Increment (the number of additional warm-up emails send daily)

This value determines how many additional emails will be sent each day during the warm-up process. The goal is to gradually increase the number of warm-up emails until you reach your set daily limit.

Example: If you set the ramp-up increment to 2, here’s how it will work:

This process continues until the daily limit of 40 emails is reached.

Typically, your email account will be fully warmed up within 3 to 5 weeks.

Click the “Start” button to allow lemwarm to send custom emails and replies on your behalf.

You can do it from the Warm-up section

or directly from the Dashboard by clicking on the Start button

In case you are not able to start the lemwarm, make sure to check the DNS section and to see if you have set up MX records, SPF, DKIM, DMARC and Custom tracking domain.

Now that you have started the lemwarm, you now sit back and monitor the process. No need to do anything from your side, as the lemwarm will send and reply to the emails ✨

These emails will resemble real ones, but you’ll recognize them by the keyword "lemwarmup" in the subject line. All lemwarm users are sending these emails to one another, simultaneously helping each other in the warm-up process.

As you'll be receiving lemwarm emails from other users, you don't want your lemwarm emails to mix up with the rest of your emails.

This is easy:

➡️ Go to your email account

➡️ Create a filter dedicated to emails with "lemwarmup" as a subject

➡️ And click the 3 boxes as below:
