If you want to stay out of the spam folder, just creating great emails is no longer enough. You also need to have the right technical setup to make sure emails land in the primary inbox. And when you factor in multiple domains and cold email outreach, plain old Gmail just doesn’t cut it anymore.
Inframail is a tool that, when used right, can help you improve email deliverability, do your email setup and mailbox creation, and make sure your email accounts drive real results.
But is it the best cold email infrastructure in the game, or can you get better value elsewhere? Let’s find out.
What is Inframail and who is it for?
Inframail is a cold email infrastructure that allows you to create Microsoft email inboxes and prepare them for cold email outreach. Inframail helps you buy domains, automatically set up SPF, DKIM, DMARC records, and more, and get started with outreach.
Top Inframail features
Inframail is a specialized email marketing tool for businesses and agencies that send a lot of emails to cold audiences.
The top features in Inframail include:
- The ability to create unlimited inboxes and purchase domains through Inframail
- Microsoft-backed architecture
- Instant IP swaps (in case something goes wrong)
- AI copy email generator
- Spam checker
One notable thing about this platform is that it doesn’t come with email warmup. You’re still going to have to purchase an additional warmup tool to get the full benefits of all the multiple IPs and inboxes you’ve purchased.
Inframail pricing
Inframail has only two pricing plans and you can purchase both on a monthly or annual basis. When purchasing for a year up front, you get 20% off each plan.
The first plan is called Agency Pack and it starts at $215.8/month when billed annually + tax. As the name suggests, it’s built for agencies that need a cold email infrastructure for outreach.
This plan is good for around 200 meetings, and it comes with:
- 3 dedicated IPs
- Free automation to set up emails
- Unlimited email inboxes
- Priority support
- No extra cost per inbox
- 15 domain setups per day
On top of that, you get 100 free domain migrations and 545 million data points.
The second plan is called Unlimited and it starts at $85.8 per month, giving you one dedicated IP, free automation, unlimited email inboxes, priority support, no extra cost per inbox, and 5 domain setups per day.
Another key difference is the 70 free domain migrations per day instead of 100.
Real reviews from Inframail users
We really wanted to write out this section, but we couldn’t. When you scour the web, across Reddit, Capterra, Trustpilot, G2, and every other platform, there is simply no review of Inframail as a tool for email infrastructure.
And since there is no free plan or free trial, the only way you can try out Inframail is by purchasing the Unlimited plan.
The best alternatives to Inframail for your cold email campaigns
If you need more than email infrastructure or you simply cannot trust a tool with no social proof, worry not. Below, we compiled some of the best alternatives to Inframail to improve your email deliverability.
Woodpecker
Woodpecker is a cold email outreach platform built for professionals who want personalized, one-to-one campaigns at scale, while ensuring inbox placement and warm-up are baked into the process.
Top features
- Built‑in email warm‑up and verification: Automates inbox warming and cleans your contact list to prevent bounces and preserve domain health.
- Deliverability safeguards: Offers adaptive sending, inbox rotation, daily domain audits (SPF/DKIM), spam-word detection, bounce shield, and send-rate controls to avoid spam filters.
- Sequence automation & A/B testing: Build multi-step campaigns with conditional triggers, split tests up to five versions, reply detection filters (including out-of-office auto-pauses), and timezone-based scheduling.
- Team collaboration & CRM sync: Add unlimited users and mailboxes at no extra seat cost, and connect via integrations (API, webhooks, HubSpot, Pipedrive, Zapier, etc.).
- Add-ons: Optional extras include LinkedIn outreach ($29/mo per account), agency panel ($27/mo per active client), white‑label reporting ($5/client), and more.
Pricing (all prices in USD/month, billed monthly; annual billing saves ~33%)
Considerations
❌ Steeper learning curve than simple email tools. Requires planning for sequences and deliverability settings
❌ Not designed for sending standard newsletters or transactional blasts. Focused entirely on cold outreach.
User reviews
✅ “We set up about 1,000 appointments a month… for half the cost of an SDR.”
✅ “Deliverability feature set—warm-up, verification, inbox rotation—is strong.”
❌ Some users note that advanced tiers are needed quickly once volume grows.
Why Woodpecker is a strong EmailOctopus alternative
While EmailOctopus excels at affordable newsletter distribution, Woodpecker is designed for dynamic cold outreach with deliverability built in.
You get sequence automation, warm-up, inbox protection, verification, and team collaboration, all in one place. For sales-driven email campaigns, it’s a far more complete solution if you’re investing in outreach, not just broadcast.
Mailreef
Mailreef is a cold email infrastructure solution designed for agencies, outreach-focused businesses, and large teams that need to run high-volume campaigns from multiple inboxes with complete technical ownership. It offers dedicated servers, IPs, and mailbox control, giving you more independence than fully managed platforms.
Top features
- Dedicated mail server and IPs: Each user gets their own outreach server and sending reputation, reducing the risk of shared blacklisting.
- Unlimited mailbox potential: Host over 150 inboxes per server with one-click creation and domain setup.
- Full authentication support: Automatically configures SPF, DKIM, and DMARC to ensure domain trust.
- Live support and spam protection: Includes technical assistance and anti-abuse screening to prevent spam behavior from affecting deliverability.
- Developer and integration tools: Offers API access and integrations with Smartlead and Instantly for campaign automation.
Pricing
Mailreef offers three plans:
- Agency – $240/month (annual commitment) + $0.001 per email sent
- Agency Flex – $249/month (monthly billing) + $0.001 per email sent
- Enterprise – Custom pricing
All plans include the same infrastructure features, mailbox automation, and monitoring tools.
Considerations
❌ No free trial or entry-level plan
❌ High upfront commitment required for most users
❌ No public user reviews available to assess real-world performance
❌ Not ideal for beginners or users who want a plug-and-play experience
Why Mailreef works as an Inframail alternative
Mailreef, like Inframail, focuses on the infrastructure side of cold emailing, but it gives users more direct control over servers, domains, and inbox creation. It’s ideal for experienced agencies that want to build and manage their own email environment rather than rely on a managed service.
While it lacks a trial option and public user feedback, Mailreef is a strong pick for teams that need scale, flexibility, and hands-on deliverability management.
Maildoso
Maildoso is a cold outreach platform that offers fully managed inboxes, domains, and deliverability safeguards to help B2B teams run high-volume campaigns without handling the technical setup themselves. It’s built for scale, with pre-configured infrastructure and centralized inbox management.
Top features
- Pre-warmed inboxes and domains: Purpose-built infrastructure designed for cold email from day one.
- SPF, DKIM, DMARC, and MX setup: Basic email authentication and DNS records are managed on your behalf.
- Domain forwarding and master inboxes: Consolidate replies from multiple mailboxes into one view.
- Reputation monitoring: Includes daily inbox placement and reputation checks to track sender health.
- Scalable infrastructure: Plans support dozens to hundreds of mailboxes and domains, making it suitable for outreach agencies.
Pricing
Pricing is tied to the number of inboxes and domains:
- $100/month: 32 mailboxes, 8 domains, 3 master inboxes
- $166/month: 68 mailboxes, 17 domains
- $733/month: 400 mailboxes, 100 domains
All tiers include SPF/DKIM/DMARC setup, inbox monitoring, and domain redirect setup.
Considerations
❌ Deliverability issues reported despite setup precautions
❌ No DNS-level access for users, limiting integration flexibility
❌ Domain replacements with low-trust extensions (.click, .xyz) may reduce reply rates
❌ Lack of customization for master inboxes and limited control over technical settings
❌ Platform stability concerns and heavy reliance on support for basic functions
User reviews
✅ “Even with all the preventative measures, inboxes still seem to get affected quickly—might be campaign-related.”
❌ “We can’t configure DNS or connect the domains to other tools.”
❌ “Every single domain was burned in a day during a large-scale issue… support replaced them with .xyz instead of .com.”
Why Maildoso works as an Inframail alternative
Like Inframail, Maildoso removes the technical barrier to cold email infrastructure by offering a fully managed service. It’s a good fit for teams that want speed and simplicity over control, especially when scaling across dozens of mailboxes.
However, it falls short for users who need domain flexibility, customization, and hands-on access. If your team values hands-free setup and doesn’t need deep integrations or DNS control, Maildoso can be a viable, though riskier, alternative.
Mailscale
Mailscale is built for senders who need to scale cold outreach across multiple domains and inboxes without relying on traditional email platforms. It handles the technical setup behind the scenes so users can focus on outreach, making it ideal for lead generation agencies, solo consultants, and outbound sales teams.
Top features
- Instant inbox generation: Create up to 1,000 inboxes for sending cold emails without setting up each one manually.
- Automated authentication setup: SPF, DKIM, and DMARC are pre-configured for every inbox to improve deliverability.
- Domain purchasing and management: Buy and manage secondary domains directly inside the platform.
- Email forwarding and warmup: Automatically warms up inboxes and routes replies to a central address.
- Tool integrations: Connect Mailscale with your preferred outreach platform using built-in integrations and managed infrastructure.
Pricing
- Solopreneur – $63/month: Up to 2,000 prospects, 15 inboxes, DNS and email setup, live support
- Business – $95/month: Up to 10,000 prospects, 50 inboxes, access to cold email scripts, deliverability consultant
- Enterprise – $199/month: Up to 30,000 prospects, 200 inboxes (expandable at $1/inbox/month)
Considerations
❌ Domain pricing is not transparent until after you subscribe
❌ Forced domain purchasing can be more expensive than using external registrars
❌ Inbox warmup takes longer than some competing tools
❌ No support for adding inbox profile pictures, which may affect open and reply rates
User reviews
✅ “Domain pricing was higher than advertised and only visible after subscribing.”
✅ “Would love flexibility to bring in my own domains instead of buying through the platform.”
❌ “The warmup process takes 2–3 weeks, but it’s still cheaper than most alternatives that offer this.”
Why Mailscale works as an Inframail alternative
Mailscale and Inframail both aim to simplify cold email infrastructure, but Mailscale goes further by handling everything from domain setup to inbox provisioning in one platform. It’s especially useful for high-volume senders who don’t want to get bogged down in DNS records or manual warmups.
While it lacks transparency in pricing and limits domain flexibility, it delivers strong value for teams looking to scale cold outreach with minimal technical setup.
Mailforge
Mailforge is a cold email infrastructure platform built for users who need more than just an outreach tool. It helps teams create, warm up, and manage multiple mailboxes and domains for high-volume sending without harming deliverability, making it a strong fit for outbound agencies and fast-scaling sales teams.
Top features
- Multi-domain email infrastructure: Create and manage multiple sending domains and inboxes to reduce risk and boost inbox placement.
- Email warmup and validation: Warm up new mailboxes automatically and verify contacts before sending to minimize bounces.
- ChatGPT-powered content engine: Generate unique variations of outreach emails at scale to avoid spam filters.
- Unified inbox: Manage all conversations across domains and campaigns in one dashboard.
- API and webhook support: Integrate with your existing stack for real-time updates and control over campaign workflows.
Pricing
- Pro – $48/month for 1,000 active contacts in sequence and 5,000 emails/month
- Growth – $96/month for 10,000 active contacts and 50,000 emails/month
Considerations
❌ Reporting and analytics are fairly limited
❌ No built-in LinkedIn outreach or calling features
❌ USD-only pricing may be a barrier for some teams
❌ User interface can be complex and unintuitive for first-time users
User reviews
✅ “The interface is way too complex… it needs a redesign to make it easier to work with.”
✅ “We’d like to see better analytics and native LinkedIn automation, but those features are on the roadmap.”
Why Mailforge works as an Inframail alternative
While both Mailforge and Inframail focus on cold email deliverability infrastructure, Mailforge gives you more hands-on control over your domains, inboxes, and outbound strategy.
It’s ideal for teams managing multiple brands or clients and looking to maintain high deliverability across a large contact base. If you’re okay with a slightly steeper learning curve, Mailforge offers more scale and flexibility than Inframail.
Conclusion
Inframail does a limited set of things, but it does them well. There are a couple of problems, however. It’s fairly expensive, and it doesn’t give you any warmup or automation features. To launch full campaigns, you have to invest money in even more tools. And when you factor in the lack of reviews, it’s hard to trust Inframail as a cold email tool.
