I needed a tool to warm 30+ inboxes.

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.

❌ 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.

  • ❌ 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.

  • ❌ Occasional integration issues

    Some users experienced failures or disconnects when trying to integrate with inbox providers like Gmail.
  • ❌ Not beginner-friendly

    The platform’s interface and workflow aren’t always intuitive, especially for users new to cold email tools.


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.

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. 

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.

  • 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

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

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.

Truly Inbox alternatives
This image shows the Truly Inbox alternatives
Use Case Best Pick Avoid If…
Scaling 30+ inboxes ✅ Warmforge ❌ You’re only warming 1–2 inboxes occasionally
Fast bulk inbox creation ✅ Inframail ❌ You need inbox health insights or alerts
High-volume campaigns + reporting ✅ Mission Inbox ❌ You’re not ready to manage 50+ inboxes yet
Fast setup with no manual steps ✅ Maildoso ❌ You need deep tracking or custom deliverability rules
Reliable warm-up on a tight budget ✅ Mailscale ❌ You want advanced DNS control or IP rotation

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 Warmforge here, no setup headaches, no guessing, just a clean warm-up that works.
