We can access the services through the Internet or through a software that I can use on my workstation. I can clean the data from different angles. Review collected by and hosted on G2.com.

Not much. If I have trouble with anything the tech support is readily available to get me through it. Review collected by and hosted on G2.com.

I like the free 1000 credits, which can at least get you going. I like the Bulk upload function using listware. I like the fact that it takes less than a minute to get the data ready. Review collected by and hosted on G2.com.

I feel that there can be improvement in understanding the result code in the address lookup section. When you download the result file it will be helpful if the bad addresses are automatically highlighted instead of the user decoding the file. Review collected by and hosted on G2.com.

The dataquality suite does a good job of ensuring mailing addresses are USPS verified. The Presort library for actually compiling a bulk mailing would often break when updates were released and it took tech support an average of a week to fix the issues. This meant not being able to do bulk mailings for a week which is not conducive for running a business. Review collected by and hosted on G2.com.

When new updates come out undocumented changes in the code breaks our implementation leading to days of work getting everything working again. Tech support knows NOTHING about the changes that are made in updates so they are completely worthless to turn to for help.

Very poor, practically non-existent documentation.

Cryptic (if any) error codes returned from the object.

No input validation in the library so strings that are too long cause the library to crash without any information about why it crashed.

No documentation showing the maximum string length that can be put into each field of the library which makes the above problem darned near impossible to solve. Review collected by and hosted on G2.com.

Melissa is the most accurate and best address service.

It has a very friendly API available in a variety of formats (SOAP, REST, others).

Melissa offers a huge array of different fields that can be used for many practical business purposes, both about the customer and about the addresses you submit. Review collected by and hosted on G2.com.

The only drawback I found was there wasn't a PHP SDK available out of the box. I ended up writing one and open-sourcing it, and a number of other people are now using my SDK. It's not the end of the world, other services don't have that as well, but it'd be nice if they'd offer that. Review collected by and hosted on G2.com.

User interface was clean and intuitive

Pricing was the best that I found

Data came back quickly and clean Review collected by and hosted on G2.com.

I did not experience any cons. It performed exactly as I hoped Review collected by and hosted on G2.com.

Easy list view and single record view buttons that allow users to make bulk updates easily. Review collected by and hosted on G2.com.

Listware vs. CleanSuite gets a bit confusing, and feels like a half-baked transition to a newer version that wasn't full fleshed out. Review collected by and hosted on G2.com.

Customer service. It was pretty good to me. Review collected by and hosted on G2.com.

The results aren't the best user experience. Review collected by and hosted on G2.com.

Listware is very intuitive, and inexpensive for cleaning small data sets of less than 10,000 records Review collected by and hosted on G2.com.

Nothing in particular, it does exactly what I need Review collected by and hosted on G2.com.

Price was my main focus on this - I had around 10,000 addresses that I needed cleaned for a bulk mailing and somehow found melissa, the pricing allowed me to purchase one-time and was SUBSTANIALLY cheaper than anyone else I could find -- I ran all my data (also very quick) and when I sent to printer only 18 addresses came back (out of 10,000 that is amazing!)

Their user interface to get to the bulk upload tool was a little difficult to find **note** I contacted customer service and got a response immediately and they walked me through how to get there, so the dislike was very minor Review collected by and hosted on G2.com.
