"Flexible Email Warm-Up with Seamless Salesforge Connection"

5/5

What do you like best about Warmforge?

It connects automatically if you have Salesforge.

The warm-up settings are flexible: you can control how many emails to send, the timing, etc. There is a warm-meter that helps estimate if your mailbox is ready for a real operation.

You can also set up a filter so your inbox doesn't turn into a 'trash bin' once the warming process starts. The design and everything else are on the same level as the rest of the *forge infrastructure. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

No complaints—it's just a good, useful tool.

Probably the only downside is the thought of how much energy is being consumed globally by these kinds of warm-up processes. Review collected by and hosted on G2.com.

It helps stabilize deliverability and gives confidence that emails are landing where they should. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

The platform is intentionally focused, so advanced customization options are limited. That said, the simplicity is also part of the appeal, and it works well for its core purpose without unnecessary complexity. Review collected by and hosted on G2.com.

What problems is Warmforge solving and how is that benefiting you?

Warmforge solves the problem of poor inbox reputation and inconsistent deliverability when scaling outbound email. Before using it, warming inboxes required manual effort and guesswork.

"warmup for cold emails became easy"

5/5

What do you like best about Warmforge?

the simplicity to upload mailboxes and have the warmup process integrates with the other apps namely Salesforge and infraforge. Currently I have 71 mailboxes being warmed up and it took me a few seconds to upload them. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

In the beginning it takes a while to understand all their apps and how they interact with each other. Warmup only starts a few hours after all is set. Review collected by and hosted on G2.com.

"An Essential Tool for Anyone Serious About Email Deliverability"

5/5

What do you like best about Warmforge?

I really like how the warming flows feel like genuine human interactions, not just robotic spam. This realistic approach is key to staying out of spam folders and building a sustainable, long-term reputation with email providers. It gives me peace of mind. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

While the 'Heat Score' is great, the overall reporting and analytics are a bit basic. I'd love to see more historical data and trends on deliverability performance for each domain over time, directly within the dashboard. Review collected by and hosted on G2.com.

What problems is Warmforge solving and how is that benefiting you?

The direct benefit is a significant increase in our campaign effectiveness. By ensuring our emails consistently land in the primary inbox, Warmforge boosts our open rates, reply rates, and ultimately, the ROI of our entire outreach effort. It provides the foundation for all of our campaigns to succeed. Review collected by and hosted on G2.com.

"Reliable Email Warm-Up That Works"

5/5

What do you like best about Warmforge?

Warmforge quickly improved my deliverability with AI-driven warm-up that mimics real human sends, opens, and replies. The Heat Score dashboard makes it easy to track progress, and multi-inbox management is a big time saver. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

Setup requires DNS/SPF/DKIM knowledge, so non-technical users might struggle. Reporting is basic, and pricing can add up if you only have a few inboxes. Review collected by and hosted on G2.com.

What problems is Warmforge solving and how is that benefiting you?

Warmforge solves the problem of poor email deliverability for cold outreach.

Before using it, my emails often landed in spam or promotions, hurting response rates. The AI warm-up gradually built sender reputation by mimicking real, natural email activity—sending, opening, replying, and even removing emails from spam.

The benefit is simple: now my cold outreach consistently lands in the primary inbox, open rates are higher, and I spend less time troubleshooting deliverability issues. It’s also easy to manage multiple inboxes from one place, which saves a lot of time. Review collected by and hosted on G2.com.

"Great tool to keep your cold mailboxes warm and alive!"

4.5/5

What do you like best about Warmforge?

I tested several tools to increase mailboxes reputation. The warmforge is one of the best: easy to use, fully integrated with mailforge and salesforge, and more important - it works fantastically good! None of my emails, mailboxes and domains need to be constantly replaced any more! Customer support is nice and prompt. Highly recommended to everybody who need infrastructure for cold outreach. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

Actually I don't know why they moved warming-up to the dedicated product. But as all *Forge tools are integrated it is not a problem at all. Review collected by and hosted on G2.com.

"Easy Setup for Mailbox Warm-Up, Awaiting Long-Term Results"

3.5/5

What do you like best about Warmforge?

Getting started was seamless—I was able to submit mailboxes for warm-up without any issues. The platform is user-friendly and straightforward, which is a big plus when you're managing multiple tools and domains. So far, it’s doing what it promises in terms of onboarding. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

The pricing seems a bit steep, starting at $12 per mailbox. For anyone managing a larger volume, this could get expensive fast. If there were volume discounts or bundling options with other tools, it would be more compelling. At this stage, I’m also still waiting to see measurable impact from the warm-up process. Review collected by and hosted on G2.com.

What problems is Warmforge solving and how is that benefiting you?

We use Warmforge to warm up new mailboxes before launching cold outreach campaigns. This is crucial for improving deliverability and avoiding spam filters. While we're still in the early stages and waiting to see measurable results, the setup process was very smooth and everything worked as expected. Review collected by and hosted on G2.com.

"overall great experience with Warmforge"

5/5

What do you like best about Warmforge?

I've been using Warmforge for a few months now, and it's been a game-changer for our cold email outreach. Before Warmforge, we struggled with deliverability issues—many of our emails were landing in spam folders, and our open rates were disappointingly low.

What sets Warmforge apart is its AI-driven approach to email warm-up. The platform simulates genuine human interactions by sending and receiving emails that mimic real conversations. This strategy has significantly improved our sender reputation, ensuring that our emails land in the primary inbox rather than being filtered out. Review collected by and hosted on G2.com.

What do you dislike about Warmforge?

Nothing - I think this solution is comprehensive. Review collected by and hosted on G2.com.
