"Started off fine, but now it's a ghost land and loads mailbox with garbage"
0/5
What do you like best about Mail Warm?

This product worked well in the beginning. Then all of the sudden it stopped working and support disappeared. The software is supposed to send 40 emails per day to warm my address, but the data is showing that it sends about 5 or so. I also get littered with junk emails now. Review collected by and hosted on G2.com.

What do you dislike about Mail Warm?

There's not much to like about this mail warm. There is no support to be found, their system doesn't work, and my mailbox is littered with garbage emails. It doesn't do what it says it will. Review collected by and hosted on G2.com.

"Like its simplicity & ease of use"
4.5/5
What do you like best about Mail Warm?

The simple and easy-to use SMTP tool from TopicMojo is perfect for those who need a reliable way of sending emails. With its user-friendly interface, you can have an account set up in no time at all! Review collected by and hosted on G2.com.

What do you dislike about Mail Warm?

The roadmap is not being updated enough. Many integrations are coming soon, which was to be expected for new software but I would like it even faster than that! Review collected by and hosted on G2.com.

"Great email warmup tool to increase email reputation"
4.5/5
What do you like best about Mail Warm?

The tool does what it is supposed to do, improve email reputation and prevent emails from landing in spam. They use human-like email opening patterns so that it doesn't look unnatural. I also like the team as the founder has a good reputation because of his past products. Review collected by and hosted on G2.com.

What do you dislike about Mail Warm?

Currently, there is only an SMTP option to connect, and apart from how to connect articles some basic articles like how to use and all are missing in the knowledgebase. Review collected by and hosted on G2.com.

"Mailwarm delivers"
5/5

There's still a lot of development to be done but it is happening at a very decent pace. I am happy overall Review collected by and hosted on G2.com.

"Promising"
5/5
What do you like best about Mail Warm?

Looks pretty promising. I have a couple of domains to be warmed up. Of course, warming takes quite some time, so we will see how it will work out. UI looks pretty straightforward, thus easy to use. Review collected by and hosted on G2.com.

What do you dislike about Mail Warm?

As of today, you can add inboxes only via SMTP. All the major providers are there to choose from, but they are all greyed out, so I hope that they will launch them soon. Review collected by and hosted on G2.com.

"Must have product for cold email game"
4.5/5
What do you like best about Mail Warm?

Easy to use, straightforward UI. Adding new email accounts to the dashboard was quick and it is easy to see the whole process statistics in a single dashboard. Review collected by and hosted on G2.com.

What do you dislike about Mail Warm?

Currently only available for SMTP, they are planning to integrate with Gmail / outlook / yahoo / AOL, Amazon, and a bunch of other email providers. This is pretty much the only thing I am waiting / dislike about mail warm. Review collected by and hosted on G2.com.

"Promising Product but still need some Polish"
3.5/5
What do you like best about Mail Warm?

The interface looks pretty clean and easy to get started. The SMTP and Gmail set-up is quite easy almost no learning curve is needed. The support doc is short but clear. Review collected by and hosted on G2.com.

What do you dislike about Mail Warm?

As a new application. So far it only supported SMTP and Gmail. The verification email that landed on my spam folder made me a bit worried at the first point. But the app works fine. Review collected by and hosted on G2.com.
