In 2025, Warmy.io continued to evolve our offerings with a series of powerful new features designed to enhance email deliverability, streamline email management, and improve user experience. Let’s take a closer look at some of the most impactful updates that have rolled out in 2025.
Major enhancements to user control and customization
Report generation for a more indepth look at the data
From the User Dashboard, users can now generate domain-level reports without needing to dig into individual user accounts.
- Simply head to the Reports tab, select your domains, and let Warmy handle the rest.
- Users can also track the report’s progress in real time, from “In Progress” to “Completed,” and download them in XLSX or PDF format once they’re ready.
- For large datasets (over 500 domains), reports are bundled into a neat ZIP file with separate XLSX files for each batch.
These reports include detailed statistics that give you a comprehensive view of domain performance, making it easy to track key metrics and spot trends. Here’s a quick overview of the information you can expect to see:
- Health Score: A quick snapshot of the domain’s overall health, based on its reputation and performance.
- DNS Records: Details on SPF, DKIM, and DMARC settings for authentication.
- Deliverability: Breakdown of how well your emails are being delivered to recipients’ inboxes.
- Spam Rate: Insights into how often your emails are marked as spam by recipients.
- Sent and Received Today: Counts of how many emails were sent and received during the day.
- GPM Status: Gmail Postmaster (GPM) status, including your domain’s reputation and spam rate as reported by Gmail.
Additionally, you can choose to add more customizable statistics, like:
- Deliverability Checker Statistics (Inbox, Spam, Promotions, Unreceived): A breakdown by period (Today, Yesterday, Last 7 Days), showing how emails are classified across major providers (Gmail, Outlook, Yahoo, etc.).
- Warmup Statistics (Sent, Landed in Inbox, Saved from Spam): How well your emails performed in the warmup process, helping you track progress and optimize sending behavior.
Enhanced deliverability and IP management
Customizable Warmup Preferences
This powerful new feature gives senders complete control over the email warmup process by providing options for fine-tuning and optimization. These include:
- Setting custom distribution percentages for email warmups across major email providers, including Gmail, Outlook, Zoho, and Private SMTP. This helps create a natural, diverse sending pattern that mimics organic traffic behavior.
- B2B & B2C targeting: Choose whether your warm-up emails should resemble engagement typical of B2B (business-to-business) or B2C (business-to-consumer) interactions. This customization ensures that your emails are better positioned for inbox placement based on your audience type.
Whether you want to adjust settings for all your mailboxes at once or fine-tune individual senders, you can easily modify warm-up settings directly within your Warmy account. Adjust how you balance traffic across different providers without any hassle.
Warmup with Clicks to maximize warmup results
Warmup with Clicks incorporates human-like engagement to ensure your emails don’t just land in the inbox during the warmup process. Instead, they’re actively interacted with, improving both domain reputation and inbox placement.
Traditional seed lists often require senders to manually download lists, upload them to their Email Service Provider (ESP), and track each email’s performance. While effective, it’s also time-consuming and prone to errors.
With Warmup with Clicks, the process is fully automated. All you need to do is connect your mailbox to Warmy, and the system takes care of the rest. The warmup includes both IMAP and seedlist recipients, allowing for better deliverability. There’s no longer any need to manually download seed lists to ensure contact lists are updated.
Here’s where the magic happens: emails are opened, links are clicked, and even if an email is initially sent to the spam folder, it is moved to the inbox and marked as important. These natural interactions send positive signals to email service providers (ESPs), showing that your emails are legitimate, relevant, and wanted by the recipient.
Since the system ensures only valid and actively engaged email addresses are included in the warm-up, bounce rates are reduced, improving your overall sender reputation. With Warmup with Clicks, you’re not just sending emails. You’re actively building trust with inbox providers, boosting deliverability, and improving sender reputation in a completely hands-off way.
Smart weekly auto-run for email deliverability test
This update allows users to set up automatic weekly tests to monitor inbox placement performance, ensuring that they can consistently track your email deliverability without manual intervention. Here are some things to know about this feature:
- Users can now configure the test to run automatically on specific days at a domain and mailbox level. They can choose the specific day or select the “auto pick” option.
- All active mailboxes within the domain will be part of the test. Even when a new mailbox is added, it will automatically be included in the automatic tests without any additional setup.
With this new functionality, you can save time and ensure that your inbox placement is always being tested without needing to manually set it up each week.
New Notification Hub
Listening to user feedback, we’ve moved beyond the limitations of email-only alerts and introduced a multi-channel notification system that provides more flexibility, better engagement, and greater control:
Here are the changes we’ve implemented:
- Notifications can now be sent via email, SMS, and webhooks, with plans to integrate Slack and WhatsApp in the future.
- Users can now set custom notification receivers for each channel, ensuring the right team members get the right information. You can also choose which notifications you want to receive, whether it’s about mailbox changes, seedlist updates, or other critical events.
Get immediate notifications for important changes, including mailbox states and seedlist events, so you can act quickly and keep email operations running smoothly. - Users have full control over your notification preferences, enabling you to tailor alerts to your needs. By default, mailbox notifications are enabled, but you can adjust them as you see fit.
Other notable updates
While we’ve introduced several major updates in 2025, there are also a number of other enhancements that further improve the overall user experience. Here’s a quick rundown of the latest features:
- API Key Management: With the new API Key Management feature, users can now securely generate, view, and manage their API keys directly in-app, eliminating the need for outdated email/password methods. This enhances security, reduces support tickets, and simplifies third-party integrations, enabling smoother API adoption and scalability.
- Inbox Academy: Through practical video lessons, the self-service Inbox Academy guides marketers, founders, and support teams in fixing inbox issues and improving email campaign performance without requiring any technical skills. Plus, users who have successfully finished the course will get their very own “Deliverability Expert” certificate.
- Redesigned UI on the app side: The revamp includes an improved overall look and usability of the dashboard, designed to make processes easier for users.
- Template Checker browser extension: This plugin allows users to quickly analyze and validate their email templates for deliverability before sending them out. With a simple click, users can check for potential issues like spammy language, improper formatting, and other factors that may negatively affect inbox placement, ensuring their emails are ready to perform at their best.
- Connection of mailboxes via CSV file: Simply upload your CSV file, and Warmy will handle the setup, with real-time tracking, smart error handling, and email alerts. This update saves time and boosts efficiency by eliminating manual entries.
- Seed List improvements: Warmy’s latest Seed List Improvements allow for more detailed engagement tracking across all seedlist receivers, including metrics like emails moved from spam, emails read, and links clicked. These statistics are displayed in real-time charts, enabling better insights into seedlist performance and easier monitoring. This update helps users track engagement more accurately and detect potential system abusers more efficiently.
- Unique Seed List Split Feature: This feature eliminates duplicates across multiple splits by ensuring no receiver is reused within active or archived seedlists for a user. This setting helps avoid confusion, improves seedlist management, and reduces CSM/CS ticket volume.
- API for seedlist: This allows users to manage their email warmup Seed Lists programmatically, making it easier to automate tasks and integrate with other applications. You can retrieve data, manage approved senders, and download Seed Lists—all through the API, further automating your email management processes.
- Spintax on the user template (plain text): Warmy’s Spintax feature allows users to create one email template with multiple unique variations, making it easier to personalize messages and reduce the risk of being marked as spam. It supports nesting for even more flexibility, and automatically alternates email variations for a more natural communication flow. You can preview and test the variations to ensure optimal deliverability and engagement.
