I keep contacting the customer support and yesterday they told me the error is on their side, but today, they acted like everything works fine on their end, asking me what's the error I receive. When I mentioned I have the same error from yesterday and they were supposed to fix this in a few hours, I stopped receiving any replies even though they state they offer 24/7 support. I have to provide full report to my clients about the mailing but I can't show anything while the tracking system is off. This was a huge setback to my business so I can't help but give them a bad review.

The software does what is it stated The software does what is it stated. It may seem simple and with a bit outdated design, but it satisfies my needs. I use Verifier to clean up my list. It requires some pre set up, but once I configured it with the support stuff, it is working smoothly till now. Mind it won't validate yahoo emails, but the story is the same with other validators I tried.

Long Time User I've been using Atomic Park for many years and have no reason to go to any other software.

It’s the best software ever I have been searching for a good and reliable software to allow me send bulk mails continuously but I couldn’t find one not until I found Atomic Email sender .. The software is very easy to install without malware or virus and very easy to setup including the smtp setup. The customer service live chat have also been a very good help and good assistant(GALINA) she’s always very happy to attend and answer my numerous questions. Thanks a lot to Atomic email sender and Creator..
