5 TrulyInbox Alternatives & Competitors for 30 Email Accounts (Based on Real User Feedback)

I needed a tool to warm 30+ inboxes, which is a common challenge for businesses managing large-scale email outreach.

TrulyInbox looked simple and cheap. Perfect, or so I thought.

Then I checked the reviews.

Inbox failures. Broken Gmail integrations. No visibility.

One user said:

“Sometimes the integration with gmail fails.

There are too many filters and rules that need to be set up.

Its not as straightforward as it seems when tackling an overflowing inbox.”- user review on g2.com

That’s when I stopped and started digging.

I didn’t want others to waste weeks testing tools that crumble at scale.

So I found five Trulyinbox alternatives and analysed real campaign results

✅ TrulyInbox Alternatives Comparison

❌ Why TrulyInbox Doesn’t Scale in 2025

TrulyInbox works well for basic warm-up needs, but many teams reported clear limitations as soon as they tried to scale beyond 10–15 inboxes.

Here are the key reasons it falls short in 2025:

• ❌ Poor customer support
  
  ‍Several users mentioned that customer support was unresponsive or unhelpful when issues came up.

Read the full user review

• ‍❌ Complicated setup with Gmail
  
  ‍Setting up TrulyInbox with Gmail often required too many filters and manual configurations, making the process less straightforward. Complex DNS configuration is often required, which can be a barrier for non-technical users.

Read the full user review

• ❌ No full email service features
  ‍
  TrulyInbox is only for warming, it doesn’t offer full email sending or management features like Outlook or Google Workspace. It also does not address inbox placement or ensure that emails are delivered to the primary inbox.

Read the full user review

• ❌ Occasional integration issues
  ‍
  Some users experienced failures or disconnects when trying to integrate with inbox providers like Gmail. Email providers evaluate sender behavior and trust signals, so if integration is not robust, messages may be blocked or filtered by spam filters, impacting deliverability.

• ❌ Not beginner-friendly
  ‍
  The platform’s interface and workflow aren’t always intuitive, especially for users new to cold email tools. The lack of workflow automation makes it harder for sales teams to manage large-scale cold outreach campaigns.

• ❌ Inbox failures
  
  ‍Messages are not always delivered to the primary inbox, often ending up in spam or promotions due to poor inbox placement.

In the email deliverability space, tools must address not just email warmup but also deliverability, inbox placement, and integration with sales workflows. For example, a sales team running a cold outreach campaign might struggle with TrulyInbox because their messages are not delivered to the primary inbox, limiting sales engagement and campaign success.

So, TrulyInbox is suitable for small use cases but not built for growing teams.

How We Found TrulyInbox Alternatives in 2025

Instead of relying on product pages or vague marketing promises, we went deep into what real users and cold outreach agencies shared online.

We analyzed feedback from those managing 30+ inboxes across 5 domains, the kind of setup most outreach teams work with. For example, we reviewed scenarios where a user coordinated multiple campaigns across several domains to optimize deliverability and track performance.

Here’s what we focused on:

🧪 Real-world Setups Shared by Users

• Most users were managing bulk inboxes across multiple domains
  
  
• Tools were used for daily warm-up flows over extended periods
  
  
• Clear patterns emerged once the account volume passed 10–15 inboxes

💡 What We Looked to Learn

We weren't just comparing features. We wanted to understand:

• Which tools consistently scaled past 30 inboxes
  
  
• Which platforms gave users real visibility and control
  
  
• And which ones helped keep email deliverability stable across large outreach workflows

✅ TrulyInbox Alternatives That Can Actually Handle 30+ Inboxes

We started seeing issues with TrulyInbox once we crossed 12 inboxes, drops, spam landings, and no real way to monitor what was happening.

So we looked for tools that could reliably handle 30 or more inboxes without the usual chaos.

These alternatives are designed to ensure that your email messages are delivered to the primary inbox, improving inbox placement and helping you avoid spam filters.

This is especially valuable for businesses and sales teams running cold outreach campaigns, as these tools help improve deliverability with major email providers. Advanced email warmup and workflow automation features also set these alternatives apart from basic tools.

So we read real users’ reviews on G2 and Reddit, and other platforms to sort this out.

Here are the 5 TrulyInbox alternatives they explored:

• Warmforge – Best overall pick for control, scale, and inbox health
  ‍
• Inframail – Great for bulk inbox creation with unlimited slots
  ‍
• Mission Inbox – Built for high-volume teams needing deep monitoring
  ‍
• Maildoso – Fast setup, good for scaling 30–50 inboxes quickly
  ‍
• Mailscale – Budget-friendly, flexible warm-up automation

Let’s go deep into each tool.

2. Inframail – Good TrulyInbox Alternative for Bulk Inbox Creation

When I looked at user feedback for TrulyInbox alternatives that focus on speed and volume, Inframail consistently showed up in reviews and discussions.

Most said TrulyInbox started becoming unstable after 12 inboxes. Manual DNS setups and tracking became a bottleneck. 

Inframail, on the other hand, offered a way to create unlimited inboxes under a flat-rate plan, with no extra charges or restrictions.

While users liked the scale and ease, a few pointed out limitations like minimal control over warm-up pacing and a lack of spam placement visibility.

🔑 Key Features of Inframail 

• Unlimited Inbox Support – Flat fee covers large-scale setups
  
  
• Automates DNS Configs – No need to touch SPF, DKIM, DMARC
  
  
• Quick Launch – Set up cold email infrastructure in minutes
  
  
• Simple to Use – Great for teams needing speed over complexity

• Setup took under 45 minutes
  
  
• Created and warmed all inboxes on the same plan
  
  
• No issues with limits or onboarding

✅ Our Verdict on Inframail

If you're focused on volume and fast execution, Inframail is a strong TrulyInbox alternative.

It’s not built for advanced deliverability control, but it shines when you need to create and manage inboxes at scale without billing headaches.

3. Mission Inbox – TrulyInbox Alternative Built for High-Volume Outreach

Mission Inbox came up repeatedly when users needed a warm-up tool that could handle scale and give them deeper visibility.

From what I gathered, it's best suited for agencies managing 30+ inboxes across multiple domains. 

Reviews praised its monitoring features, live deliverability alerts, and ability to manage inbox health in real-time. 

While the setup takes a bit longer, it gives you more control over performance and reputation.

If you're looking for a scalable TrulyInbox alternative with pro-level diagnostics, Mission Inbox is a solid pick.

🔑 Key Features of Mission Inbox

When I reviewed real user feedback, Mailscale kept coming up as a low-cost but reliable warm-up option for 30 inboxes.

It doesn't offer the full infrastructure control of tools like Warmforge, but it does the job well.

How to Pick the Right TrulyInbox Alternative

Not every tool fits every use case. 

Here’s a quick guide based on what we actually saw from real user insights.

Still unsure? Start with what matters most: scale, speed, or control.

Then match the tool that delivers on that, without overcomplicating your stack.

Our Verdict: What Worked Best for 30 Email Accounts

TrulyInbox was fine until we pushed past 10 inboxes. Then things started to break.

If you're warming 30 or more inboxes, you'll quickly notice the gaps: no control, no visibility, and inboxes that silently drop.

Warmforge, on the other hand, gave us everything TrulyInbox couldn't:

• ✅ Full control over DNS, warm-up behavior, and routing
  
  
• ✅ Real-time health tracking, spam alerts, and domain monitoring
  
  
• ✅ Zero inbox drops during our entire test run
  

We didn't have to guess what was working. We could see it, fix issues early, and scale without breaking things.

If you're serious about cold outreach and ready to grow past basic tools, Warmforge is the most complete TrulyInbox alternative we've used.

You can get started with here, no setup headaches, no guessing, just a clean warm-up that works.
