"Economic but little less accurate with results."
2/5
What do you like best about Atomic Mail Verifier?

The results are quick, and the user interface is pretty neat. There are not many buttons and functions that make it easy to use. It has little section where we see the analytics of bounce/undelivered vs delivered. Review collected by and hosted on G2.com.

What do you dislike about Atomic Mail Verifier?

It uses port 25 to scan, which is a hassle. It burns the IP address, which is one of this software's most harmful features. Often the results are not accurate. We get more uncertain data means it is neither valid nor invalid. Review collected by and hosted on G2.com.

What do you like best about Atomic Mail Verifier?

nothing. this is not working and can burn your IP because its need post 80 the nobody sells Review collected by and hosted on G2.com.

What do you dislike about Atomic Mail Verifier?

i buy all the studio after I chat with them and they were very nice, I explained that I want to use proxy and from where I bought the proxies. they say all is fine and no problem. after I buy : 1. the verifier needs proxies port 80 that nobody sells. IF YOU WILL USE THE VERIFIER WITH DIRECT CONNECT YOU WILL BURN YOUR IP 2. the list manager doesn't work and they want me to change my computer reg in order to make it work... (who touch the reg of the computer for a software) 3. when I ask refund or part refund they say all is fine and no refund. my advice, don't buy! Review collected by and hosted on G2.com.

What do you like best about Atomic Mail Verifier?

Atomic Email Verifier – the best one of the competitors. The feature I liked the most is the possibility to choose between one-time purchase or pay-per-emails verified in Atomic Email Verifier Online. It’s a cheap, easy, and fast way to upgrade your email list. Review collected by and hosted on G2.com.

What do you dislike about Atomic Mail Verifier?

I haven't found any cons, maybe the design isn’t ideal for someone but I don't think that’s a problem for any software. Review collected by and hosted on G2.com.

"Doesn't work very well anymore if your port 25 is closed."
2/5
What do you like best about Atomic Mail Verifier?

It used to be the most awesome, best and least expensive email verifier on the market. All the other companies charge your per email checked, and this is a one time fee.

The software works FAST, I'm able to triple-verify 10,000 emails in less than 2 hours. The sending process couldn't keep up.

It works really well and does check many different parameters, removing spam traps and throwing away old emails from your lists. Review collected by and hosted on G2.com.

What do you dislike about Atomic Mail Verifier?

For the past year there is a new problem which is that it doesn't work anymore if your port 25 is closed, which is the case for most networks (my office, my university, my library, my home). The only way around this is the put it on a dodgy virtual private server, but we use google apps in our organization which ALSO has port 25 closed. This means we're unable to use this amazing software. Review collected by and hosted on G2.com.

"Great way to keep your bulk email lists clean"
5/5
What do you like best about Atomic Mail Verifier?

I like that I can upload my lists to the program and have it check the validity of the email addresses - not just server response codes, but also domain validity and syntax correctness (allowing me to fix issues, possibly, without just scrubbing out an email address that otherwise could be recovered). It is quick and efficient. If you are an email marketer, you know that the more problematic/bad email addresses you have in your list, the worst your sender IP reputation becomes -too many any you find yourself increasingly blocked by recipient ISPs, and/or your mass email service/IP blacklisted (or canceling your service). Online email verification services charge per email tested. This company charges $69 for the software and that's it for lifetime. Review collected by and hosted on G2.com.

What do you dislike about Atomic Mail Verifier?

The only drawback is that it is Windows only, not Mac. Aside from that, there is nothing I have found that I don't like yet. That they charge me once for a lifetime license is just great. Review collected by and hosted on G2.com.

"This saved our poor marketing efforts (and saved us from all the lists we purchased)"
4/5
What do you like best about Atomic Mail Verifier?

The ability to clean up a database with 40,000 "leads" only to discover that 10% of them were verified email addresses -- saving us from going into trash, spam, and the dreaded undeliverable bin. Review collected by and hosted on G2.com.

What do you dislike about Atomic Mail Verifier?

Costs, because we're a start-up money is incredibly limited. Review collected by and hosted on G2.com.
