I evaluated Microsoft's DQS which could not scale over 100,000 customer records. DQS actually supported calling MelissaData Matchup in the old Microsoft Marketplace (no longer available) to use it's more sophisticated matching but it was a moot point if DQS can't handle the volume.  

Yes, we tried Pitney Bowes, Service Objects, Trillium, Texas A&M, Informatica. We also considered USPS and Google Maps, though they didn’t fit into our model.

I believe we evaluated other products offered by Melissa Data at the time (for example, “Mailers”). I do not know that there were other vendors offering what we needed at the time. Other vendors had options for sending batch data files, but no options for us to be able to write our own code.

Unfortunately, I can't remember the other products we looked at. 

The only other product we are currently using is Whitepages Premium. It provides the information necessary, except for an email address sometimes. We also looked at Spokeo and other append services. Melissa caught my attention because we had previously worked with their address verifier and I knew it was a good solution for our needs.

SAS, Experian.

AddressDoctor, Experian, PostcodeAnywhere.

I just did a Google lookup and found Melissa Data, that's how I got there.

Yes, I cannot name other vendors.

We evaluated Whitepages.com.

Yes, we did review other NCOA provider software.

We looked at Service Objects and a few others. Some of these vendors had poor documentation, pricing was not competitive, or the product did not provide the customization we needed.

I still use D&B, Synthio, Discover.org and RainKing, but Melissa Data is always a contender for B2C data needs.

Regarding advice to others looking for similar solutions:

1. Explore Melissa's products and services online.
2. Speak with one of their sales reps.
3. Schedule an online demo.

Zscrubber. Melissa Listware Online is much easier.

I can’t recall all the other solutions in detail; Trillium was one.

We just researched on the internet. There weren't a lot of choices - we're going back probably 13 years - back then as there are now. 

We've only used this one.

We evaluated top results in Google.

We also evaluated and requested a quote from Experian, which was far more expensive.

Yes, but too long ago, I don’t remember which.

No. I've used Melissa Data zip code products in the past, and became interested in their additional offerings.

Did not evaluate other options.

Yes, we evaluated other options. Not disclosing them at this time.

Satori. You have to call to purchase credits, unless you want to spend a couple thousand dollars a year to purchase unlimited NCOA. When I called I got voicemail. Wanted something quicker.

No.

Various reverse address, reverse name people search programs; none of them worked for what I need.

We investigated various solutions and decided that Melissa was the best fit for our business and customers’ businesses needs.

There are no other viable options.

Google, USPS, SmartyStreets.

We did evaluate other products, but the particulars are confidential.
