"Fast, Intuitive Bulk Domains & Mailboxes with Seamless *forge Integrations"

5/5

What do you like best about Mailforge?

Everything is fast and intuitive—buying domains and mailboxes in bulk is seamless; you can use AI to generate names based on your main website. As with all other *forge products, there's a neat integration with buying leads, or setting up sequences. Review collected by and hosted on G2.com.

What do you dislike about Mailforge?

Honestly, there’s nothing to complain about; everything is reasonable and right at your fingertips Review collected by and hosted on G2.com.

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

This is the tool that helped me build the foundation for my cold outreach and mass email campaigns.

I set up several domains here—you do this to avoid ruining your main inbox due to spam risks—and it’s relatively cheap, definitely on par with market rates.

Then I quickly connected several mailboxes. If you have Salesforge, they will start warming up immediately, which is a great feature.

You can also export all your mailboxes to another similar tool; the functionality for that is right there. Review collected by and hosted on G2.com.

"Effortless Email Management, Essential for Consultancies"

5/5

What do you like best about Mailforge?

I use Mailforge for the entire infrastructure of my GTM and RevOps consultancy and it's a crucial part of everything we do inside ALPN Digital and for all our clients. Mailforge handles everything related to mailbox and domain sourcing, management, setup, and configuration. It's a pain to manage across fragmented tools, but Mailforge makes it easy. Also, since it's tied to a full system, it makes life very easy and efficient. I really like the simplicity and ease of use; it saves us time, keeps us lean, and increases efficiency. Usually, we manage everything for our clients, but in cases where they want to own everything, it's a simple and easy-to-use platform that we can comfortably put in people's hands, knowing they won't get lost or confused. The initial setup was too easy. Review collected by and hosted on G2.com.

"Effortless Cold Email Setup, Streamlined Campaign Launches"

4.5/5

What do you like best about Mailforge?

I appreciate Mailforge because it gave us an option compared to doing the whole buy domains + create mailboxes + configure SPF/DKIM/DMARC + tracking process manually (or bouncing between a bunch of tools and a DNS dashboard). We used it at our agency to spin up cold email infrastructure for new client campaigns fast Review collected by and hosted on G2.com.

What do you dislike about Mailforge?

Sometimes their UI is counterintuitive for example when switching plans such as reducing the number of mailboxes, I wish they had a better mobile experience as it's still kind of clunky to make changes from mobile Review collected by and hosted on G2.com.

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

Our main challenge was having an affordable way to use different kinds of mailboxes that were not too prone to being banned or trigger spam filters, if we had gone the normal route we would've had to pay a lot in godaddy domains and then buy licenses for each mailboxes whether its google or microsoft only to get banned. Instead mailforge allowed us to quickly set up mailboxes and start sending relatively fast Review collected by and hosted on G2.com.

"Mailforge Simplifies Outbound Inbox Setup and Scaling Cold Email"

5/5

What do you like best about Mailforge?

Mailforge makes setting up and managing outbound inbox infrastructure much simpler than doing it manually. The provisioning process is straightforward and it helps keep domains organized when running multiple campaigns. It saves time and reduces technical friction when scaling cold email. Review collected by and hosted on G2.com.

What do you dislike about Mailforge?

The platform works well overall, but more visibility into inbox health metrics and domain performance over time would be helpful. Additional reporting around warmup progress and reputation signals would make optimization even easier. That said, the core functionality is solid and reliable. Review collected by and hosted on G2.com.

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

Before using Mailforge, setting up and managing multiple outbound inboxes required more manual work and technical setup. It was harder to keep domains organized and maintain a consistent infrastructure as we scaled campaigns.

Mailforge simplifies inbox provisioning and domain management, which reduces setup time and keeps everything more structured. It helps us scale outbound more confidently while maintaining stability across multiple domains. Review collected by and hosted on G2.com.

"One of the best custom SMTP inbox providers"

5/5

What do you like best about Mailforge?

Ease of use, mass editing, automatic setups, instant chat support with real people, cost efficient.

Works very well with Salesforge, connecting everything seamlessly with just a click. Review collected by and hosted on G2.com.

What do you dislike about Mailforge?

Inbox creation customization options.

You either have to create each inbox individually (albeit from within the platform and faster than fully manual creations), or let the system auto create them for you (removing the option of picking your preferred alias@ inbox names). Review collected by and hosted on G2.com.

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

Getting domains and inboxes at scale for outbound. Works equally well with all prospect email providers and will change email servers if deliverability starts going wrong with the current one.

Huge time saver, because everything is consolidated into one place, and most of the tedious processes, such as DNS records setup, are automatic. Review collected by and hosted on G2.com.

"Efficient mailbox that nicely connects with the Forge system"

5/5

What do you like best about Mailforge?

Simplicity, functionality and that I can check the emails without needing to go to my MS inbox separately. All is one place. Their support has been amazing and very swift in replying to all my requests at any time that I have contacted them. It was very easy to set up and connect with the outbound campaign builder, so now my email replies from clients land there letting me quickly connect with them and book my demo calls. Review collected by and hosted on G2.com.

What do you dislike about Mailforge?

It may seem a bit too simple and standardized to some, but that really depends on how complex of a solution someone is looking for. To me things should be very simple and practical and that's what I get from Mailforge. Review collected by and hosted on G2.com.
