"For only $9 to warm up 10 accounts is a steal! The interface is clean and simple to navigate. If you have cold email accounts to warmup, this is a no-brainer deal to jump on." - info0744bPLUS, Verified purchaser, AppSumo
This pricing structure is particularly appealing for small businesses, offering flexibility to scale as outreach needs grow.
Warmforge doesn’t just save on costs - it also saves time. Its automation features handle the entire warm-up process, including sending, receiving, opening emails, and crafting human-like replies.

For added security, Warmforge includes continuous health checks. These monitor critical settings and blacklists, providing early warnings of potential issues. For small businesses without dedicated IT support, these automated checks are a lifesaver.
Warmforge has earned glowing reviews, with ratings of 4.9/5 on G2 and 4.8/5 on Product Hunt. Users frequently highlight its ease of use and affordability. While some have noted occasional bounce rate issues or slower customer support, the overwhelmingly positive feedback speaks to its reliability and effectiveness.

Lemwarm blends automation with tailored personalization for different industries. As part of the lemlist ecosystem, it taps into a network of over 20,000 real users across 100+ countries to naturally boost your sender reputation.
Lemwarm offers two pricing plans to suit various business needs and budgets:
Plan | Monthly Price | Key Features | Best For |
---|---|---|---|
Essential | $29 per email | Generic warm-up emails, technical setup checks, deliverability reports | Small businesses starting email outreach |
Smart | $49 per email | Personalized emails, industry-specific clusters, custom alerts | Growing businesses with targeted campaigns |
If you're already using lemlist, the Essential plan is included at no extra cost, and you’ll get a $29 monthly discount on the Smart plan. You can save even more with quarterly (10% off) or yearly (20% off) billing options. These pricing options make Lemwarm a budget-friendly choice, especially for small businesses looking to scale their outreach with automation.
Lemwarm simplifies the email warm-up process by sending and receiving messages through its network of real accounts - steering clear of fake email addresses. Its Smart Cluster technology takes things a step further by tailoring warm-up emails to your specific industry and email objectives. This warm-up phase typically lasts 3–4 weeks, during which open rates start at around 50%. With continued use, open rates can climb to as high as 80%.
"Warming up email address is the most underrated thing to do when approaching cold email outreach", says Jimmy Ewins.
The platform also adjusts sending volumes automatically based on your domain's performance, ensuring consistent engagement and maintaining a healthy sender reputation.
Lemwarm integrates seamlessly with major email providers and supports protocols like SPF, DKIM, and DMARC. It also monitors sending volumes to avoid blacklist issues. While it’s part of the lemlist ecosystem, Lemwarm works well with other email infrastructures, making it a flexible option for businesses with existing setups.
Lemwarm doesn't just stop at automation - it also provides real-time insights to help you maintain an optimal sender reputation. The platform offers daily reports on email performance, technical setup, and sender reputation. Its deliverability dashboard uses a three-stage score meter - Red (risk of blacklisting), Orange (warming up), and Green (optimal deliverability). A healthy score typically falls between 85 and 100.
The dashboard tracks key metrics like the number of emails sent and those rescued from spam folders. It also provides actionable tips to fix deliverability issues.
"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!" shares Harris Kenny.
Real-world results underscore Lemwarm’s effectiveness. For instance, Devlo improved open rates by 27% by following Lemwarm’s DNS check recommendations. RightMarket reached thousands of customers without hitting spam folders, and SalesCaptain doubled its Fortune 1000 client wins. Additionally, Lemwarm automatically corrects email misclassifications by providers and advises pausing campaigns when deliverability scores dip, safeguarding your long-term sender reputation.
Reply is a sales engagement platform designed to combine email warm-up with multichannel outreach. Unlike tools that focus solely on email, Reply takes a broader approach by offering multiple ways to connect with prospects.
Reply provides tiered pricing based on the number of active contacts:

Reply stands out with its automation capabilities, making outreach more efficient. The platform's Deliverability Toolkit includes over 20 features for automated email warm-up and deliverability optimization. It also uses AI to suggest email content that avoids spam filters.
One of Reply's key features is its multichannel sequences. These sequences allow businesses to connect with prospects through email, LinkedIn, WhatsApp, SMS, and phone calls. By using Zapier, these channels are seamlessly integrated. The platform's AI even selects the best communication channel for each prospect based on their behavior.
Another standout feature is AI-generated responses. These responses handle follow-ups, answer common questions, and even schedule meetings. This is especially beneficial for small businesses looking to maintain consistent outreach without adding more staff.
Reply integrates smoothly with major email providers, CRMs like HubSpot, Salesforce, Pipedrive, and Copper, and personalization tools such as Hyperise, Vidyard, and Albacross. Users can connect these tools via API or no-code solutions like Zapier and Make.com. Additionally, Reply works with Calendly to simplify meeting scheduling, allowing prospects to book directly from email sequences.
This flexibility lets businesses create a tailored sales stack that fits their workflows and tools. The seamless integration not only supports campaign performance but also enhances deliverability.
Reply's deliverability suite, powered by Gmail API integration, keeps tabs on key metrics and provides actionable advice for campaigns. It tracks sender reputation and offers recommendations to maintain strong email performance.

Mailwarm is a high-end email warm-up tool that utilizes over 1,000 email addresses to simulate real engagement, ultimately improving email deliverability.
Mailwarm offers three main pricing tiers tailored to businesses of varying sizes:
Plan | Monthly Price (Annual) | Monthly Price | Email Accounts | Warm-up Emails/Day |
---|---|---|---|---|
Starter | $69 | $79 | 1 | 50 |
Growth | $159 | $189 | 3 | 200 |
Scale | $479 | $549 | 10 | 500 |
The Starter plan, priced at $69 per month with an annual subscription, positions Mailwarm as a premium solution. However, its feature set is designed to justify this cost.
Mailwarm emphasizes automation to maintain a strong sender reputation. Once configured, the platform runs autonomously, mimicking human email interactions by opening messages, starring key emails, and generating replies. It also includes Auto Warmup Scheduling, which allows businesses to align warm-up activities with their typical email sending patterns. Additionally, its blacklist monitoring feature keeps tabs on whether your email address appears on spam databases, offering peace of mind.
Mailwarm integrates seamlessly with popular email marketing platforms like Mailchimp, ActiveCampaign, and Constant Contact. This makes it easy to incorporate into existing workflows.
For businesses with custom systems, Mailwarm provides a real-time email validation API. This feature allows bulk email verification to remove invalid contacts before launching campaigns, helping to improve deliverability rates.
Beyond automation and integrations, Mailwarm focuses heavily on deliverability metrics. It monitors bounce rates, spam rates, and other key indicators, alerting users to potential issues. This is critical, as studies show that over 21% of legitimate emails fail to reach recipients' inboxes.
If your email address is flagged on a blacklist, Mailwarm offers guidance to help resolve the issue and restore your reputation.
That said, user feedback on the platform is mixed. Mailwarm holds a G2 rating of 3.7/5 from 14 reviews. Some users have reported issues such as frequent bounces during the warm-up process and dissatisfaction with the quality of the generated warm-up emails and replies.
Despite these criticisms, Mailwarm’s focus on detailed deliverability monitoring and bulk email verification makes it a solid choice for businesses that value in-depth insights over budget-friendly options.

Here's a closer look at the strengths and weaknesses of each tool:

Warmbox | Budget-friendly at $15/month for a solo plan; quick and easy setup; great for single mailbox operations | Limited scalability; lacks advanced features; basic analytics |
Lemwarm | Strong personalization features; detailed deliverability reports; solid ratings (4.5/5 on G2, 4.6/5 on Capterra) | Expensive at $29/month per email; navigation challenges in the UI; high costs for multiple mailboxes |
Reply | Full integration with outreach platforms; comprehensive sales automation; ideal for teams needing all-in-one solutions | High price at $49/month per user; may be excessive for simple warm-up needs; steeper learning curve |

The table highlights the essentials, but let’s break things down further, focusing on pricing, usability, scalability, and integrations.
When it comes to affordability, Warmforge leads the pack with pricing as low as $3 per mailbox for bulk users, making it a great option for growing businesses. On the other hand, tools like Folderly and Mailwarm are on the higher end of the spectrum, with costs that can quickly add up, especially for businesses managing multiple mailboxes. As Fabian Maume, CMO of Warmup Inbox, puts it:
"I always assess whether the software offers a good balance between features and pricing."
User experience varies significantly across these tools. Warmforge and Warmbox are noted for their straightforward interfaces, making them accessible even for beginners. In contrast, Folderly and Reply are more complex, which might deter smaller teams or those without dedicated IT support. As Maume explains:
"The first thing I look for is how intuitive the interface is. If it's hard to use, the team won't fully adopt it."
Scalability is another key consideration. Warmforge stands out with its bulk pricing model, making it a cost-effective choice for businesses looking to scale. In contrast, tools like Lemwarm and Folderly can become prohibitively expensive as mailbox numbers grow, which may not be ideal for startups or small businesses.
The range of features varies widely. Tools like Warmbox and Mailwarm focus on the basics of email warm-up, which can suffice for many small businesses. On the other hand, Folderly offers advanced AI analysis and deliverability insights, appealing to those needing deeper functionality. Meanwhile, Reply excels in integration, offering seamless connections with outreach and CRM tools, making it a strong choice for teams seeking a more comprehensive solution.
Interestingly, customer reviews don’t always align with pricing. Warmforge, despite being one of the most affordable options, boasts an impressive 4.9/5 rating on G2. Premium tools sometimes receive lower scores due to their complexity and higher costs, which can alienate users looking for straightforward solutions.
For small businesses, the key is finding the right balance between functionality and affordability. Aligning tool capabilities with specific business needs ensures efficiency without overspending.
Selecting the best email warm-up tool ultimately hinges on your specific business needs, budget, and growth trajectory. Here's a breakdown tailored to different small business scenarios:
For startups with limited funds:
Warmforge is a standout choice, offering bulk pricing starting at just $3 per mailbox. It also boasts excellent ratings and provides new users with one free warm-up slot, delivering great value for tight budgets.
If you only need to warm up a single email account:
Warmbox is a straightforward option. Its solo plan costs $15 per month and holds a solid 4.4/5 rating on Product Hunt. This makes it a practical pick for individual users or sole proprietors.
For businesses planning to scale, it's worth considering tools that cater to growing teams.
For expanding teams:
Warmforge shines here too, thanks to its cost-effective bulk pricing. It allows growing businesses to manage multiple accounts without breaking the bank.
Email warm-up tools are a game-changer for small businesses aiming to improve email deliverability. They work by gradually increasing the number of emails sent from a new or dormant account, helping to build the sender's reputation with email providers. This slow and steady approach reduces the risk of being flagged as spam, ensuring your emails are more likely to reach inboxes.
What makes these tools even more effective is their ability to simulate engagement. By generating replies and interactions, they enhance the account's credibility in the eyes of email providers. For small businesses, this translates to fewer emails ending up in spam folders and a more reliable way to connect with customers and prospects.
When selecting an email warm-up tool, small businesses should focus on a few important factors to ensure it aligns with their needs. Cost is a big one - pick a tool that fits your budget but still delivers quality results. You also want something that's easy to use, with a straightforward interface that doesn’t require a lot of time to set up. Another must-have is automation, as it saves time by managing the warm-up process on its own.
It’s also worth looking for tools that provide detailed analytics, so you can monitor email deliverability and track your sender reputation over time. Make sure the tool is scalable, so it can grow with your business, and check if it offers integration options to work smoothly with your current email platform. Lastly, having access to dependable customer support can make a huge difference if any problems arise. By keeping these factors in mind, you’ll be able to choose a tool that simplifies email outreach and keeps your messages out of the spam folder.
Small businesses can absolutely integrate email warm-up tools with their current email marketing platforms, and doing so can make a big difference. By linking these tools, businesses can automate the warm-up process while still running their regular email campaigns. This approach improves email deliverability and strengthens the sender reputation, all without the hassle of managing multiple systems.
This setup helps emails avoid spam filters, ensuring they reach recipients' inboxes. For small businesses with limited resources, this streamlined method not only saves time but also enhances the effectiveness of their marketing campaigns.
