Inframail is a popular tool for businesses doing cold outreach as it provides a solid foundation for companies conducting email outreach at scale.
However, as your business grows, your needs evolve too. And though Inframail is very much capable, it lacks advanced functionalities needed to scale your campaigns effectively. Meanwhile, Warmy is an Inframail alternative for businesses seeking more than just a seamless cold email infrastructure setup.
If you’re an Inframail user exploring other options for better performance, improved deliverability, and advanced features, you’re in the right place. As with any tool, it may not be the best fit for every business at every stage.
In this guide, we’ll explore top Inframail alternatives and provide detailed insights to help you find the best option for your cold outreach needs.
What is Inframail and how does it work?

Inframail is a platform that offers an easy and streamlined setup of email infrastructure for cold email outreach efforts. With Inframail’s ability to automate the email infrastructure setup, email senders can get mailboxes set up and ready to use in just a few minutes. Without it, setup can take a longer time and can be very tedious.
For marketing agencies handling multiple clients, Inframail’s comprehensive dashboard allows them to manage various and multiple mailboxes simultaneously.
Inframail features: where Inframail excels
- Reliable infrastructure thanks to Microsoft-backed IPs. Inframail stands out due to its strong infrastructure which provides a strong foundation that guarantees better deliverability and ensures emails don’t get flagged as spam.
- Unlimited inboxes at a flat rate. Inframail allows businesses to create unlimited email inboxes at a flat rate, which is definitely a major advantage over traditional email services and expensive platforms like GSuite. Senders can do away with rising costs that come with creating new email accounts.
- Easy integration with cold email platforms. The seamless integration with popular cold email tools like Smartlead and Instantly enables users to easily export inboxes and get started with their outreach campaigns.
- Dedicated email hosting for better control. Senders’ email reputation remains in their control, and will not be affected by the actions of other users.
- Automatic SPF, DKIM, and DMARC setup. This ensures compliance and security without requiring manual intervention.
- IP and domain health deliverability dashboard. Users can monitor their inbox placement and take necessary actions to avoid landing in spam folders.
- Auto-delisting feature for blacklisted mailboxes. If any of your mailboxes or domains get blacklisted, Inframail automatically submits delisting requests.
- Phantom redirect feature for better deliverability. This feature ensures that domain redirects are hidden from email service providers. This helps avoid spam filters, which improves the chances of your emails landing in inboxes.
Inframail limitations: where Inframail lacks
- Dedicated email hosting is a double-edged sword. If senders don’t follow best email sending practices, they will end up damaging their reputation across all domains and addresses.
- Setup is quick and easy, but it doesn’t necessarily translate to the best deliverability rates.
- Dashboard is straightforward, but doesn’t offer granular and in-depth analytics or reporting features.
- Given the features and capabilities, the cost is a bit on the expensive side.
Why should you consider Inframail alternatives?
While Inframail gets the job done, there are several reasons why email marketers might consider exploring alternatives:
- Pricing concerns. Inframail pricing plans can be less accessible for smaller businesses that are just starting their journey. The cost may also not be justifiable for the features the platform offers.
- Limited scalability for campaigns aiming for a wider reach. Inframail is a good option for small-to-mid-sized businesses (SMBs) and startups. However, for businesses aiming to scale quickly, its capabilities and features still need to keep up.
- Deliverability and reputation management. While Inframail offers features designed to improve email deliverability, it doesn’t specialize in email warmup and reputation management.

Key benefits of Warmy.io for email campaigns
When it comes to finding the best alternative to Inframail, Warmy stands out. While Inframail and other cold email infrastructure platforms focus primarily on setup and mailbox creation, Warmy addresses multiple layers of email deliverability while providing tools to maximize inbox placement and improve campaign performance.
Warmy doesn’t just stop after warming up a domain or email address. It also continues to act as a reliable business partner by offering advanced tools and features such as:
AI-powered email warmup strategies

Warmy leverages artificial intelligence to optimize the email warming process. It smartly adjusts the warmup frequency and content, ensuring each email sent feels authentic and personalized.
The AI-driven warmup automation mimics real human interactions, such as opening emails, scrolling through content, and clicking on links. This process helps maintain a positive sender reputation, reducing the likelihood of your emails being marked as spam.
The Warmup Preferences feature also gives senders full control over how warmup efforts are distributed, allowing senders to make adjustments per provider. For instance, if a sender wants to improve their Gmail deliverability, they can allocate more resources to Gmail’s warmup efforts.
No fake accounts—only real people
One of the major advantages of Warmy is that it uses its network of real people (not fake accounts) to exchange warmup emails. This ensures that the reputation boost is authentic, since email providers like Gmail and Outlook prefer genuine interactions. This also contributes to better email engagement rates and higher chances of inbox placement.
Advanced seed lists

Staying true to Warmy’s process of only using real accounts, the advanced seed lists also use real, active email addresses that interact with your messages. These emails are not just marked as read, but they are actually opened, scrolled through, and clicked. If a message lands in the spam folder, it is manually removed and marked as important, signaling to email service providers (ESPs) that your emails are legitimate.
Scalable across multiple languages
Warmy supports over 30 languages, making it an excellent choice for businesses with international email campaigns. Whether you’re reaching out to customers in Europe, Asia, or the Americas, Warmy can warm up your email addresses in the language that best suits your target audience, enhancing the overall personalization and effectiveness of your outreach.
SPF and DMARC Record Generator

Warmy offers free SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting, and Conformance) record generators to simplify the setup of these crucial email authentication protocols. These tools ensure that your emails are properly authenticated, which is essential for achieving high deliverability and protecting your domain from email spoofing.
Template Checker

Beyond the technical aspects, email content also plays a significant role in deliverability. Warmy’s free Template Checker scans email templates to ensure they are optimized for inbox placement. It checks for potential issues, such as spammy words that could trigger spam filters, and analyzes the structure and content of your email. Senders using this feature can modify content to increase the likelihood of your email reaching the inbox.
Bonus: The Chrome Extension of the Template Checker allows senders to analyze and edit their emails directly within their sending platform, making the process even more simplified.
Domain Health Hub and Free Deliverability Test

Warmy provides users with a comprehensive Domain Health Hub that tracks domain reputation, blacklisting status, and other factors affecting deliverability.
The Free Email Deliverability Test shows how well your emails would perform across various inbox providers, giving you visibility into what percentage of your emails end up in spam or inboxes.
