Testimonials

I just sent out my campaigns, which means that everything is working perfectly! I am very very happy right now. And I just wanted to let you know that the DataValidation service was really fantastic!
— Yves, Atradius.com
I have no requests. Your support was amazing, the process was seamless and you guys saved us. We tried a different company and they never returned the lists. Thank you for everything and we will continue to use your service.
— Daniel R. Donovan, maxeffectmarketing.com
I just tried really using MailChimp for the first time. Seems awesome. I imported my list and was blocked from sending it out. Their help said to delete my last import and try again. Well, then I’d have no one to send my email to! Did a little research and found that I needed to clean my list. I’d never heard of such a thing. Found one guy that would do it for $142. For my 419 names. Yikes! Searched some more and found you. Whew! Fast, easy, awesome. Did what you said and my email was sent out, no problem. Thank you! Awesome! I’ll keep using it!
— Trevor J., Jones Home Collective | Keller Williams Exclusive Properties
Hi, thanks, it's the first time I've used your service and it really helped me. I spent hours trying to remove email addresses in the hope that Mailchimp would accept my 'new' list and nothing worked. I then used DataValidation and Mailchimp immediately accepted my cleaned list. I wish I'd used you straight away.
— James R., jamesreddy.co.uk
The service has been terrific - I wasn’t expecting it to be so easy and straightforward. It is great value for money.
— Helen H., MayDay Travel Marketing
Live chat was incredibly helpful as I had no idea what I was doing! This is the first time we've had such a problem with bulk email (our last company email we sent out was 2014, to give you some idea) and your team held my hand through the process.
I will be recommending Data Validation.
— Alix T., doetaylor.com
In less than two weeks we went from an 87% reputation to 98% with SendGrid. We have pleased the ISP gods thanks to your team!
— Mikhail Avady, IP SmartUP
I was a bit desperate yesterday after MailChimp blocked one of my uploaded lists. It is clear that DataValidation solved this very quickly. Thanks a lot!
— Yves Van Hee, Atradius
DataValidation saved my life! I had to migrate the newsletter campaigns from a self-programmed system to Zoho Campaigns, and I recognized, too late, that the dataset was horrible. Zoho blocked me during the first campaign.
— Hans-Henning Schulz, Deutscher Verlag für Gesundh
I LOVE your service. I’ve used the MailChimp integration, which works like a dream. I will be recommending your service to all my MailChimp clients as a ”good practice” tool to add to their arsenal.
— Bridget Gilchrist, Tin Soldier Ltd.
Thanks very much for cleaning my list, the service works very well.
— Ross Debos, Sunday SouLounge
Super. I didn't expect the Mailchimp integration. It made everything painless.
— Philip Owen, volgatrader.com
The service I have received has been fantastic. Without any doubt the best online service I have ever had. Thank you!
— Andrés Gómez-Peña, IDB
On our first eNews to nearly 2,500 subscribers, we had only 5 bounce-backs and 7 unsubscribes. No way that would have been possible without your service! Thanks, DataValidation, for keeping us in compliance!
— Jodie Rogers, University of Oregon
You guys are awesome. I've been looking for a platform like this for 2 months to vet media contacts for my startup so I don't trash our domain in spam traps. This was the most effective tool I've found, and I'll be using it again on the consumer side as we develop a direct email marketing campaign.
— Jared Criscuolo, seededbox.com
Y’all have a great service with a nice clean, user friendly interface. Glad to be able to have multiple versions of our list to make use of. No doubt I’ll be using the services of your company again in the near future.
— Cody Reid, Brunk Auctions
I'm very pleased with how fast I got a reply to my questions. Also very satified with the price and service. Great job.
— Joshua Guilfoyle, New York City, NY
Very useful — helped us get over the hump with our first import of 6-year old data to MailChimp. Now running much more smoothly!
— Alex English, Tampa Bay Regional Transportation Authority (TBARTA)
Thanks Data Validation! It was easy to use and after I studied the definitions, I was able to re-sort my data for upload to MailChimp. In addition, your tips about sending emails to the Accepts All emails was extremely helpful!
— Jennifer Hoskins, PHR
It's awesome!! I was able to import the cleaned list of A's and B's into MailChimp no problem, whereas before cleaning with DV, MailChimp let me know a re-opt in would be required. I'm thrilled with this service!
— Lily Starling, ParkWinters.com
We tried DataValidation on advice from a colleague. The service was easy to link to Mailchimp, and was extremely affordable.
— Jodie Rogers, University of Oregon
We are VERY satisfied. Your service has refreshed our stale mailing list and contributed to the surrealistic celebration of the Domestic Research Society's 10th anniversary - high in the Julian Alps!
— Alenka Pirman, Domestic Research Team
Your service has been outstanding, and I especially liked your LiveChat feature - very helpful!
— Karen Burke, Crop King
We saved thousands of dollars that would have been spent on bounces and opt-outs by using DataValidation's cleaning tools. Now, we use their real-time protection so we never have a bad list again.
— Blake, Perdue for Senate
Thank you very much! Your service is super!
— Lexi Serebro, ToneDef.co.za
Thanks for your service, it was helpful and easy to use! MailChimp knew what they were doing when they recommended you.
— Abby Rubottom, FloridaPromise.org
We are very pleased with your service and fast turnaround time. We ran a small list through and then sampled those emails through our email platform.
— James J. Marks, Background Info USA
