    Pricing: Warmy.io offers three tailored pricing plans available upon request: B2B senders, B2C senders, and custom solutions. Warmy also offers a free seven-day trial, providing ample time to explore premium features and evaluate the platform’s effectiveness before committing to a paid plan.

    • SPF, DKIM, DMARC are set up automatically. This process saves users valuable time and reduces the chances of emails being marked as spam. 
    • One-click integrations with popular outreach tools. The need for manual CSV imports is eliminated, making it easy to scale cold email campaigns.

    Limitations:

    • As of present, Zapmail is limited to Google Workspace and Microsoft 365. Users on other email platforms will need to consider other alternatives. This can be a dealbreaker for businesses using other email services.
    • There may be some hindrances as email volumes increase.
    • Those who need detailed performance metrics might find Zapmail’s capabilities lacking.

    Pricing: Zapmail offers three pricing plans ranging from $39 to $299 per month. It is an affordable option for small businesses and mid-sized campaigns, but the pricing is a bit steep for scaling businesses. 

    3. Mailforge

    A webpage for Mailforge displays a headline about starting cold email infrastructure quickly, with statistics for active domains, senders, mailboxes, and automations in a flowchart—perfect for those seeking mailscale alternatives.

    Mailforge is a reliable MailReef alternative designed to provide users with robust email infrastructure, excellent deliverability, and automated setup.

    • Works with various sending software. Users can export their mailboxes and bulk import to other sending platforms like Smartlead, Instantly, or FirstQuadrant.

    Limitations: While Mailforge is very easy to set up, some find its interface difficult to navigate. This can make the initial setup a bit more challenging for newcomers to cold emailing. 

    Pricing: Mailforge calculates pricing based on a number of factors: emails per sequence sent, mailboxes per domain, contacts per month. They also have the SSL & Domain Masking add-on at $2 per domain per month (billed monthly) or $6 per domain (billed yearly).

    4. Maildoso

    A website homepage with the headline “Mailboxes built for outbound” in bold text. Below are stats: 4400+ users, 96% inbox rate, and 10m+ emails sent. Discover top mailreef alternatives and a pink “Start Free” button at the bottom center.

    Key features:

    • Built to scale. Maildoso is ideal for agencies, lead generation companies, and sales teams managing high-volume outreach across multiple domains.
    • Re-engineered custom domain tracking. This means senders can safely include any number of links, videos, and images in the emails without risking spam issues. Maildoso assures senders that emails will continue to be delivered with high success rates.
    • Integrates with a number of tools. Maildoso fits right in with the rest of your tech stack. It integrates seamlessly with communication tools like Front, Close, and Weezly. It also integrates with cold email software like Apollo, Instantly, and Saleshandy among others.
    • Automatic setup of email authentication protocols. All mailboxes come with SPF, DKIM, DMARC, and MX records set up within 10 minutes.

    Limitations: The use of a shared IP address system is a double-edged sword. It can help boost your deliverability if all other senders in the IP follow best practices. Other feedback include glitches with integrations, outdated interface, and limited customization options.

    Pricing: Maildoso has three pricing plans: $100/mo (32 mailboxes + 8 domains for free), $166/mo (68 mailboxes + 17 domains for free), and $733/mo (400 mailboxes + 100 domains for free). This cost-effective structure is ideal for businesses that need to scale their cold email outreach quickly while maintaining good deliverability.

    5. Inframail

    A website homepage for Inframail advertises Send More Cold Emails. Get More Clients. Showcasing a screenshot of the platform, navigation links, and company logos on a gradient background, it's the top Zapmail alternative for effective outreach.

    Inframail is a streamlined email infrastructure platform. This MailReef alternative focuses on simplicity and speed. It delivers an easy setup process. Businesses and senders looking to scale their outreach efforts can start right away, while maintaining full control over their deliverability.

    Key features:

    • Dedicated IP address with unlimited inboxes: This is a major advantage compared to platforms like Google Workspace, which charges based on the number of inboxes. The dedicated IP from Inframail ensures that you can maintain a strong sender reputation, as long as you follow best practices.
    • Automated setup of email records: SPF, DKIM, and DMARC records are automatically configured for each new inbox created. With this feature, new users don’t need to worry about the time it usually takes to set these records up.
    • Free tools: Inframail comes with free tools like the CopyChecker, which detects and removes spammy words from email content to help improve deliverability. It also has an AI Cold Email Generator, which helps users craft personalized and effective email content.

    Limitations: Dedicated IP comes with advantages and risks. Inframail is best for businesses who are confident in their deliverability practices. One thing to note is that Inframail makes the setup process quick and easy, but it doesn’t necessarily get the best deliverability results. It gets the job done, but businesses may face challenges with consistent deliverability across different email clients and campaigns.

    Pricing: Inframail offers two main pricing plans. The Agency Plan ($249/month + tax) is ideal for larger teams or agencies. The Unlimited ($99/month + tax) Plan is best for businesses that have lower-scale needs. Inframail’s pricing may be on the higher end as some alternatives offer similar capabilities at a lower cost.

    6. Mailpool

    A website page for mailpzi featuring the headline: Create your cold email infrastructure in seconds, with options to get started or book a demo. Explore mailreef alternatives below with a dashboard for managing email domains.

    Mailpool is another MailReef alternative that focuses on efficiency. In a nutshell, Mailpool minimizes the technical complexities that come with cold outreach setup. Sales teams and agencies can launch campaigns within minutes since inbox creation is fast, set up is fully automated, and cold emails are optimized for deliverability.

    Key features:

    • Integrates smoothly with existing tech stack: Mailpool can connect with popular outreach tools, so users can export inboxes via CSV or connect directly to various platforms.

    Limitations: Investing in Mailpool as a Mailreef alternative does have its downsides. For example, detailed pricing tiers are not publicly available since the pricing depends on the number of mailboxes to be availed. Additionally, Mailpool’s reliance on external providers like Google or Microsoft can mean additional costs or limitations.

    Pricing: Mailpool follows the subscription model. However, the total price is dependent on the number of mailboxes to be availed. Prices for Google Workspace and Microsoft 365 also vary. Essentially, it can be difficult for potential users to determine the total pricing cost for their needs.

    7. MailScale

    A dark-themed website homepage for MailScale, featuring text that highlights inboxes for agencies and B2B firms to boost cold outreach—positioned as a top Zapmail alternative—with prominent Start for Free buttons.

    Mailscale is a top MailReef alternative. Designed specifically for B2B businesses conducting cold emailing, Mailscale automates the creation of email accounts. If this process is done manually, it can be expensive, time-consuming, and resource-intensive. Especially for newcomers to the cold outreach industry.

    Key features:

    • Cost-efficient even when scaling. According to Mailscale, senders can save $1000 in the next three months.
    • Domain recovery assistance: In case deliverability drops due to recipients marking emails as spam, Mailscale offers assistance to recover domains within seven days.

    • Has a warmup period for newly created inboxes. This prevents new accounts from being flagged as spam and optimizes inbox placement for cold email campaigns.

    Limitations: There have been some reports on issues with deliverability and integrations. Mailscale also doesn’t have a comprehensive view of deliverability data, which is a disadvantage for data-driven businesses that want to track specific metrics.

    Pricing: Plans start at $79 per month. As you start to need more inboxes, pricing plans also go up from $119/month (Business), to $249/month (Enterprise), to $1,000+/month (Unlimited).

    Why Warmy.io is the best MailReef alternative

    When it comes to email deliverability, Warmy stands out as the top MailReef alternative. While MailReef provides a solid solution for cold email outreach, Warmy excels in ensuring your emails not only land in inboxes but also maintain a strong sender reputation over time. Plus, its comprehensive suite of paid and free tools are all designed to maximize email performance and boost cold outreach results. 

    AI-powered email warmup

    Graph showing email warmup performance with a line chart which helps with email sender reputation score. The x-axis represents dates from June 1 to June 9, and the y-axis represents email volume. Two lines indicate sent (1,200) and received (1,100) emails. Background is a soft gradient.

    Unlike MailReef, which offers a solid email infrastructure, Warmy focuses on AI-powered warmup strategies to ensure emails get past spam filters and land in inboxes. The Warmup Preferences feature also gives senders the capability to tailor the warmup distribution per provider. 

    Advanced seed lists

    Screenshot showing Warmy Established Seed List with API Endpoint

    Warmy’s Advanced Seed Lists uses real email addresses that actively interact with your emails. Your email is not just marked as read but actually opened and scrolled through. Links are clicked to improve sender reputation. If an email does land in spam, it is manually removed and marked as important to train email service providers (ESPs) to recognize your emails as legitimate.

    Senders can also use these seed lists to test their deliverability across specific providers (Gmail, Outlook, Yahoo, etc.). That way, they can identify potential deliverability issues before implementing email outreach to your actual recipients at scale.

    SPF and DMARC Record Generator

    A website interface titled Free DMARC Record Generator with a form to enter a domain for generating a DMARC record. Below the title are navigation buttons for Domain, ESP, Email, and DMARC value. A Next button is at the bottom.

    Warmy also offers a SPF (Sender Policy Framework) Record Generator and DMARC (Domain-based Message Authentication, Reporting, and Conformance) Record Generator. These help ensure your emails are correctly authenticated, which will result in high deliverability and additional protection of your domain from email spoofing. 

    Template Checker

    A user interface displays an email template focused on improving deliverability, with subject and message fields on the left and template analysis on the right, showing stats like subject length, word count, and personalization score.

    Aside from the technical angles that MailReef focuses on, email content actually plays a big role when it comes to deliverability. Warmy’s free Template Checker scans email templates to review and assess if they are optimized for deliverability.

    The Template Checker analyzes the structure, content, and potential spammy words. Armed with this information, senders can modify email content before sending out your campaigns. 

    Bonus: The Chrome Extension version of the Template Checker makes it possible for senders to analyze and edit their emails right within their sending platform. 

    Domain Health Hub and free deliverability test

    A digital dashboard titled Email Deliverability Test shows a summary of results. A circular graph indicates 9 hours to completion. Charts below display placement percentages across platforms like Gmail, Outlook, and Yahoo.

    Warmy users can use the Domain Health Hub to monitor the overall health of their email domains. The Hub includes domain reputation, blacklisting status, and other factors that affect deliverability.

    Meanwhile, the Free Deliverability Test allows users to see how their emails are performing across multiple inbox providers.
