If you have been in the industry of buying data, you will know it is almost imposable to find a data guy/ broker or company that you can trust and also deliver what they say. When I spoke to Ben over at NDG I knew I finally found what I have been looking for! Not only are there prices fair they deliver exactly what you request. East Coast Enrollment Center really appreciates you guys!!

I have done business with Ben Themme since 2014 and would not think of going anywhere else do to his service that he has provided through out all these years. I believe that Ben Themme does a fantastic job for National Data Group and I will continue to do business with them for many years to come.

Thanks to Ben and NDG for assisting us with our data list. They went above to get us the correct contacts that we needed. We appreciate it!

Me. Ben Theme is reliable and profession while we communicate. Although the data they gave us is not as accurate as we request, the experience was truly good. 4.5 stars are suitable.

National Data Group provided an updated list of contacts, pertinent to our business and were very responsive when we had questions. Highly recommend for outbound sales.

Im new to email marketing and Ben Temme is an absolute rock star with getting me the information I need! He responses to my messages very quickly and always provides me with exactly what I need. 5 stars all the way!

I have spoken with Ben Temme several times and have purchased several lists from National Data Group and they are fantastic. I have been marketing for over twenty years in different forms and forums, but email marketing is new to me and Ben has been very helpful and pleasant to deal with. The company cares about their customers and stands behind their email lists.

Ive been working with Ben and the National Data team for some time now, they are always fast and easy to work with. I would def. recommend working with them.

I worked with Jessica who was very responsive and paid great attention to detail. We are a small group, so she worked with us on a price to help our budget. I had one problem, which Ben went the extra mile to address and correct. I will definitely use this company again.

Worst experience Ive had with a data provider. Ben who owns the company gladly took our payment and set an expectation of 48-72 hrs to receive our product. 11 days with no product. On top of that, the communication was spotty at best. at the end of the day, we received no data, and was given no real reason why. Thankfully he did give us a full refund.

Great working with Ben at National Data Group. His customer service and walking me through the process was top notch. They have gained a lifelong partnership.

I have ordered multiple times from National Data Group. They have provided accurate email marketing lists which have increased the success of my business. The lists they provide have been highly deliverable and fresh. Their customer service representatives are knowledgeable and and timely in their response.I would recommend them to anyone looking for a reliable organization to grow with. Thank you again NDG for your help! Keep up the good work!

I had a project that fell in my lap at the last minute. Giving me a timeline of 24 hours. Ben Temme, responded to my request within minutes and before the end of the day i got confirmation that i would have my list within 24/48 hours. Not even 12 hrs later i have an email notification from Ben with the list i requested. Thanks Ben :) I will be reaching out to you again and would strongly recommend. :)

We have nothing but good things to say about National Data Group. Our account representative was great at staying connected with us as we got prepared to purchase our list. Fast, reliable, and great service.Thanks National Data Group for helping us get our B2B email list up to the next step! We look forward to seeing what kind of new business this brings us.

Purchased a business data list from them and was very happy with the results. Im an experienced email marketer and was happy with not only the list but the service I received. Many may make the mistake of Purchasing a list(from any company) and sending it with out having knowledge of email marketing and saying it doesnt work but if you send to the list the correct way you will receive results. Overall I was very happy with the service and the list and would recommend them to any one who asks.

I own a social media management company and I work with car dealerships specifically, having National Data group as an asset to grow their customer base is huge for us! I appreciate the quality and timeliness of the leads we receive from them. I would recommend them to anyone needing quality leads at a fair price.

This is my second purchase of leads from National Data Group. In both instances, I have received excellent assistance from my service rep, Ben. In addition to the excellent service, the pricing of their product is very competitive. Although, Im somewhat jaded by the industry, as a result of past experiences, Ive found their estimations of delivery results to be very accurate. I would not hesitate to recommend National Data Group, along with their product to other fellow business associates.

Ben T. was great to work with! Very professional, responsive and got us what we needed very quickly!

I dont normally leave feedback unless it is stellar or the other end of the spectrum. But National Data Group is FAST, PROFESSIONAL and RELIABLE and fits the STELLAR end of business decisions Ive made. I worked with Ben Temme and he advised me on strategic moves over the last three transactions Ive made with them. I started my own business three years ago and my direct emailing of newsletter information has been essential to my growth. I started by myself and now have 12 employees. Thank you, Ben at National Data Group.

Warning! We have ordered 250 thousand list that was send out over 6 hours, at least that is what National Data Group is claiming. I have observed activity on the website through out the entire process and we were getting bumps of traffic every hour or so but not a single order. The strange thing is that there was allot extremely similar IP addresses that the visits were coming in from and by similar I mean differentiated by a single letter or number. According to National Data Report we have received 721 clicks from them which is more that we actually had all that day ( according to google analytics 626 ). The actual number of visits from them was 51 yes 51 visits and zero orders out of 250 000 list ?. It just happen that I record every single visit to the website through A/B testing software. I know the source and activity of every visitor. I have attached report from National Data, if you could call that a report and actual Google Analytics. As you see $1500 we have spend was a total waste of money and time. We had zero orders, the report that we were provided with after was neither accurate, professional or even mean anything. We have no proof what so ever if the job was done as agreed upon, outside the attached XML file. I can not find a single good thing to say about that service. My personal and professional opinion (I am 10 year marketing veteran) is that that service is either extremely unprofessional or just straight up scam. Do not believe any review on here. STAY AWAY

As a customer, I found the process of procuring an email list to be easy and painless. They always promptly answer my endless questions, and were prompt about replacing the portion of the list beyond their guaranteed deliverability rate that bounced. Were currently purchasing our second list and so far, Ive had the same easy experience.

Good service and quick turnaround. I appreciate...thanks

I was very impressed with their customer service and how they immediately dealt with my questions. This group has some integrity. Something you dont see much of these days.

I have now used National Data Group twice and will continue to rely on their expertise to continue to grow my business. Their expertise has helped me both times to not only refine my needs but to help me maximize my requests.I highly recommend them to anyone looking to expand their business as their customer service is unmatched.Thank you NDG!

We have had a great experience with National Data Group. Ben was very helpful with any questions we will be working with them again in the future!

Our agency has been working with National Data Group for a little over a year now and they have always performed for us. Good lists and great communication when needed. They are always our first choice!

National Data Group has directly helped our education client by delivering high quality, accurate lists resulting in great leads and increased admissions. Quick and personal turnaround time, great customer service and all around solid company.

Excellent experience with Ben from NDG. They have been able to provide extremely targeted data that has helped enhance lead gen for our clients and our business... all at a very reasonable price!

Ben Temme has been great to work with. We had a very high success rate on our past projects and we are now working on our third project with the National Data Group.

My company bought a list from NDG that we were really excited about using. When we sent our first round of emails it turned out that more of them bounced that we had hoped. Fearing a battle I reached out to Ben Temme at NDG with my concerns about the high bounce rate. Ben could not have handled my issue more quickly nor more professionally. We will be getting future lists from NDG for sure.

What great customer service and support from Ben Temme! Not only did he provide fast and professional service, but when I made an error in my list selection - Ben made sure that it was corrected! Thank you Ben Temme and National Data Group!

I called requesting an email list of solar sales people, they said no problem and I paid the invoice. A day or two later i received the list and none of the email addresses looked like they had anything to do with solar so I tested about 60 of them and out of the responses i received they did not have anything to do with solar so I called Ben back up and said the list was not what I ordered. After a brief conversation we came to the resolution of being refunded instead of trying to get another list. They gave me a full refund as promised and we parted ways. There may have been a communication issue with what i was requesting, i am not sure they handled it and refunded me promptly.

Great service. Have just made our second order and will continue in the future.

I appreciate all the time Ben Temme spent with me. Very knowledgeable and personable guy!

National Data Group Sent Automated, Robot TRAFFIC to our website, One Hundred Percent Guranteed, we had an independent Network Engineer audit the traffic and results, as well as monitor the live traffic as it came through. The Google analytics proved that at the stroke of midnight, the traffic generator stopped. We watched this occurrence live. The second midnight hit, the site went from 50 to 80 current visitors to 0 instantly. 250,000 emails were sent supposedly in a 6 hour period. We didnt recieve one call, one email, one order, not one conversion, Zero... BEWARE****The FBI or Law Enforcement should look at this company. They are selling fake fraudulent lists.

Superb. Mike Nizzi at National Data Group has been a pleasure. We are a B2B technology company and work with several list vendors. NDG is at the top of our list. Over the past 2.5 years we have purchased 3 lists from NDG and have found them to be one of the best values in the marketplace.

Ben is great! Very speedy service which is crucial in my business.

Very high quality and professional, with adept individuals looking to provide the best services to its customers.

We needed a list for a project and our rep at National Data Group was very helpful and efficient. We had our request processed in 24 hours.

Great experience with Ben from NDG. They have been able to accommodate our complex data and email needs, quickly and thoroughly. We will be using them again.

Tryad L.L.C. has used National Data Group for 4 years. We always use NDG because they give us fresh lists that work for our clients. I dont have to worry about anything when I use National Data Group.On time. Priced fairly. Accurate info. My experience is that Ben Temme of National Data Group takes care of me - so I can take care of my clients.

What a ripoff! List was horrible. Over half of the list came back as returned. Just horrible product. Will never use again. Beware of this boiler room operation!

Ive purchased lists from National Data Group many times for my clients. They are always on target with our demographics and deliver what they promise.

Great to work with, fast responses

I have used them in the past and before now they were OK, but just recently purchased additional list and OMG!!! complete trash folks, buyer beware!!!
