Using their lead services for a long time now. Service is excellent and so is the quality. Would highly recommend to anyone looking to increase their revenue at an affordable price.

One of our clients recommended we work with DataSourceOne and have them provide leads for our business. We couldnt be happier with the results. Well worth the investment.

We have been working with DataSourceOne for over a year now and consider them a true partner to our company. I would highly recommend their services.

It is reliable and great quality of leads. It saves time so that you can focus on other aspects of your business.

Great to work with. Only three weeks in and they have generated more leads for us then we did in a 3-month period. Looking forward to growing our relationship.

DataSourceOne is our only source of lead generation and we dont have to worry about outbound prospecting. We more than make our money back for their services.

Thanks to DataSourceOne, I am able to connect with potential clients quickly and effortlessly.

I have used Data Source One for years and they have always done a great job. Great customer service and very responsive to my company’s needs.

DataSourceOne has been a great partner for us. Communication is easy and straightforward. Everyone we work with truly has our companys best interest in mind in all that they do.

The best lead company we have ever used for our company. I am so glad we found them.

Very satisfied with the leads. I would highly recommend them!

I received a list of online buyers in my area. I am completely satisfied with the work and the leads are highly accurate. Great job!

We have been using DataSourceOne for a little over 5 months to generate leads for our business. Honestly we were hesitant at first but it’s been a great experience. They’ve been great to work with.

One of the most professional companies I have ever worked with. They not only provide quality leads but quality customer service also. My company has seen tremendous growth in sales since working with DataSourceOne!

Great lead generation company!

Outstanding experience with DataSourceOne. Their leads are of high quality, with excellent conversion rate. Amazing people to work with. Highly recommend them!

Thank you so much for all the help. I am looking forward to seeing all the results in the future.

Thank you for delivering consistently awesome results!

So many bogus emails provided. Any professional company considering using one of these lists will ultimately be blacklisted due to attempting to send to so many invalid email addresses within the same companies. I would definitely recommend finding a more reliable source.

My account manager that helps me has been great and always available to answer questions. I recommend DataSourceOne to anyone who is looking for actual real leads.

We recently purchased a list from Data Source One, lists are very clean with up to date information. Were very satisfied with their team. They always offer quick service and standard data. Thanks for the great service.

Very affordable and great quality marketing list

DataSourceOne offers solid leads and more records than competitors. Rico is the best! He is always available and responds without fail!

Very professional and great leads

DataSourceOne provides high quality leads and great customer service at a really fair price. Weve been working with them for over a year and have been satisfied throughout. Thank you!

They are very helpful and our representative was amazing at answering all our questions and helping us to get the perfect marketing list to help our company grow. DataSourceOne deliver us exactly the target list we were looking for! Thanks for your help and great service.

Excellent product and responsive customer service. They are always quick to answer any of our questions. The list we got from them is accurate and gave us high response rates and most important reasonable price.

As a small business owner, I have been trying different ways to get my information in front of buyers. I decided to give Data Source One a shot because they were recommended by a friend. I was impressed by the amount of data they had, and the customer service when I did run into a couple of simply issues with parsing the data properly for my needs. I would recommend using this service.

DataSourceOne is an extremely reliable source for lead generation if you are looking for expanding your business. Highly recommend!

Doug and Rico from Data Source Onehave been a pleasure to work with. High quality leads are delivered to us in a timely manner with true professionalism. The industry knowledge on this team is second to none.

I highly recommend DataSourceOne and working with their team. They are extremely professional, and deliver on time excellent work. If you’re looking for a huge impact and great return on your investment, Data Source One is a great partner to work with to generate more business.

Their customer service was responsive and helpful when I needed it. They provided with very accurate data we need and I am sure that we are reaching the right prospects using our marketing campaign.

It’s hard to get quality leads. DataSourceOne already helped me to get many projects and helping me to increase my business on daily basis.

Great quality leads and great company to do business with. Looking forward to many more years of partnership.

Our rep, Andy is awesome. Great service and responsiveness.

Need help promoting yourself online? Look no further. DataSourceOne provide high quality list and leads for local business. This is the best investment for those wanting to grow your business! I highly recommend DataSourceOne to anyone looking to increase their customer base and online presence.

It was my first time buying leads and I was really nervous. I had heard horror stories about people getting scammed. Their sales people were super patient and answered all of my questions and the support folks were even better. The data was great and I couldnt have been happier.

Andy is good at what he does, bringing new customers to your company! Highly recommend him!

Looks good. List is full and only a couple bounces - that might be because of me though. Will order again

We have found DataSourceOnes Business list to be both accurate and easy to use. It allowed us to make educated decisions regarding the demographics of potential new markets. It paid for itself very quickly.

We purchased a business database from datasourceone for an emailcampaign. They told us to expect a 35% bounce rate, and their claimswere right on par with what we saw. We had much better results than other sources in the past. We will definitely be using them again for quarterly updates!

Weve been buying lists for years. DataSourceOne gave us the best value for our dollars. There isnt another company out there that can compete with them on price and quality.

I like this company. The staff are very nice and they have been very helpful and the leads generated are honest and genuine.

I have been purchasing leads from DataSourceOne regularly for the last 2 years. I have closed many deals from their leads. They are great to work with, the leads are reasonably priced and they are quick to respond with any issues.

We had several vendors for leads before we started using DSO. Now we have a one stop shop for all of our lists and a great data partners. You Cant beat the price and quality.

We purchased data and they said 20% bounce back but all data they have given was inaccurate and complete junk.. even 20% data was not accurate.. I asked for new data and asked for charge back too but they stopped responding..I will suggest to think before dealing with these people and check the samples first properly otherwise you will get regret as we have..They are making fool to people by providing a working sample and then after final payment complete waste data will be supplied.. Even I can provide all proofs that they have provided me a fake data which is completely useless for me... They are real cheater here in market who takes payment and stop responding after supplying the fake data.

They delivered the service on time and also had the genuine information which was very helpful for me. Thanks a lot guys!

Great leads; the best in the industry.

DataSourceOne has been a great partner. A few years ago our source of leads dried up. All of the alternatives were very expensive. DataSourceOnes leads are great and we order updates multiple times a year.

DataSourceOnes Support team has walked me through the process of how to use their products, which is very easy once shown. I recommend their products to anyone looking for a reasonably priced direct mail or email marketing list.

DataSourceOne helped launch our growth with their outstanding support. The products they provide have saved us a ton of money.

Until I found DataSourceOne, prospecting meant paying the exorbitant fees of InfoUSA. The volume of leads generated with DataSourceOnes  products allowed me to hire a sales force and quadruple my prospective efforts at a minimal cost.

My company purchased an e-mail database from datasourceone. In a test case of three different searches (approximately 1220 addresses), only a disappointing 35% of the e-mail addresses were deliverable! In fairness to the datasourceone, I sent them a spreadsheet with all the bad e-mail addresses and I asked the company to make this right. Their response most of our clients are getting 70 to 75% valid e-mails. No further response from datasourceone. I decided to scrap their database and buy a list from a more reputable source. I dont like to publically call out a company but dont want anyone else to get surprised. PLEASE USE CAUTION - you get what you pay for. Datasourceone pricing seems very reasonable. However, be sure to consider the cost of processing a large number of undeliverable e-mails. Dont make the same mistake I made.Note: After posting my review, datasourceone replied This is never a good idea [using a google e-mail account] and wont show positive results. The new list purchased from another source worked fine using my google e-mail account (80% deliverable).
