Important note about where your warm-up emails go
ZeroBounce owns all of its seed email addresses and does not send or share your email content with any other users.
Lemwarm
lemwarm completes your email warm-up process by sharing your warm-up emails with its community of users. Those messages are sent to other user domains and vice versa.
Email scheduling
To ensure the email warm-up process is as effective as possible, it’s recommended that the tool adjust email sending as necessary. Factors such as domain age, reputation, and certain deliverability risk factors can prompt the need to adjust sending volume over time.
Let’s compare lemwarm and ZeroBounce to see how they handle scheduling and recommended sending volume:
You can adjust your sending limits at any time. ZeroBounce will also auto-adjust your sending activity based on your current Warmup performance.
Regarding scheduling, you can manage all of your email warm-up activity by selecting the self-managed option. We’ll provide our list of seeds, and you can send your real email campaigns at your desired times, just like you would with a real email campaign.
Lemwarm
You can customize daily sending limits and increase the incremental volume at any time. You will also receive a notification of any issues that recommend a manual adjustment in your sending volume. However, you cannot adjust when those emails are sent.

ZeroBounce and lemwarm allow you to adjust how you manage email warm-up at any time with minor differences.
During ZeroBounce’s initial Warmup setup, you’ll be able to choose from a list of recommended sending and engagement rules based on your desired goal (build reputation, repair, boost, etc.). These categories are recommendations that can be adjusted at any time based on your current performance. Warmup will also auto-adjust activity and send as needed.
Similarly, lemwarm provides recommendations regarding how many warmup emails you should send that day or for the week based on past activity and performance. You can adjust these numbers at any time.
Email deliverabilityⓘ checks for campaigns
As the email warm-up service progresses, you’ll still need to send your standard email campaigns to your audience. Based on your current warm-up progress, you’ll likely want to know where your email will land.
Here’s how lemwarm and ZeroBounce can help you in this area:
ZeroBounce ONE™ includes Warmup and five additional tools, including the Inbox Placement Tester.
This tool allows you to send your email campaign to 20+ different mail providers, including Google, Yahoo, and others, to determine how your campaign will perform. Each of these providers has their own way of analyzing processed emails as well as different anti-spam technologies. The Inbox Placement Testⓘ will tell you how your campaign performs with each of these providers so that you can adjust your campaign as needed.
Lemwarm
lemwarm provides a publicly available email deliverabilityⓘ test. This test uses a single email account found on the lemwarm domain and provides a technical check-up as well as a content check to see if your email triggers spam filters.
Does ZeroBounce have access to read my emails?
Any email warmupⓘ service will read the emails sent to the privately-owned seed email addresses, so that they can perform realistic, authentic behaviors.
However, ZeroBounce doesn’t read any emails found in the connected inbox. The company maintains strict adherence to security and privacy regulations to protect your data.
Whether you’re a small business or a global enterprise, your company’s security and your customers' privacy rights are paramount. As a result, security and privacy are top priorities for ZeroBounce.
Lemwarm
lemwarm’s exact security specifications are undisclosed. However, according to the Privacy Policy listed on their website, they are compliant with GDPR and other relevant data protection regulations.
Who can benefit from the best email warmupⓘ tools? Any business that sends emails, especially if you have other professionals outside of your marketing team using email for outreach.
Sales teams and outreach specialists
If you don’t know any better, your business is likely sending all of its emails from the same domain (the primary business domain). The problem with this is that everyone’s activity, including the bad practices, impacts your email deliverabilityⓘ. Unfortunately, those most commonly come from the non-marketers.
If you’re in sales or outreach, regularly add huge lists of new contacts without verifying them, and send a high volume of emails, you need email warm-up.
While it’s still critical to get everyone on board with best practices (cleaning new leads, sending from subdomains when applicable), an email warm-up service can mitigate the damage by generating consistent positive email engagement over time.
Warm up business domains and subdomains
To avoid email deliverabilityⓘ damage to your main business domain and try new things, create subdomains for your different teams and use cases.
However, new domains lack a reputation and need a way to get up to speed. You can achieve this by warming them up.
Email Warmupⓘ is an excellent way to help your team quickly set up new subdomains so that your sales, BDR, and cold outreach emails will actually reach prospects instead of going directly to spam.
Email marketers and marketing specialists
Whether you opt for lemwarm, ZeroBounce, or any other lemwarm alternatives, email warm-up is now considered an essential part of the marketing and outreach process.
Even if you follow all of the best practices; validate your new leads, segment audiences, use different subdomains, and request users to opt-in, you’re still going to encounter problems. People will report you as spam for no reason, errors will cause emails to bounce, and more issues will arise that you’ll need to troubleshoot fast.
Continuously warming your email domain allows you to continue your email marketing program with peace of mind. The positive engagement you receive daily is a healthy counterbalance to the errors you may face and some of the unwarranted treatment you’ll get readers that you’re legally allowed to send to.
lemwarm is an email warmup service provided by lemlist that provides monthly domain reputation improvement for one account. Comparatively, ZeroBounce provides email warm-up as a part of its full email deliverability package, which includes essentials like DMARC, blacklist monitoring, and testing. Both platforms provide a fully automated email warm-up service.
