ReadyContacts is the best alternative to upper; ?> in terms of data, coverage, quality and a lot more.
Data.com delivers a database of companies and contacts that are aggregated from crowdsourcing and other sources. It has millions of companies and contacts that you can search from & download.
Pros: Large coverage of companies and contacts across countries. Integrated into Salesforce.com so its easy to use. Email addresses for all contacts and direct dials for some.
Cons: Crowdsourced and aggregated data inherently suffers from accuracy problems that are not ideal for targeted marketing. Limited to no technology install intelligence. Your universe of contacts for specific campaign may not be fully covered. Pricing is not affordable for businesses of all sizes.
We build every dataset fresh - so we identify target companies based on your specs (geo, installs, size & other customizable factors) and discover contacts based on your exact titles. We have built software to do this with speed & accuracy and layer in a curation process to ensure aligned with the spec. This ensures that the dataset delivered is fresh, accuracy and fully aligned to your exact needs.
We DO NOT aggregate data across other providers and simply query and deliver. This does not work. First, the data gathered from other large databases is inherently inaccurate. Second, large databases rarely have companies identified by the criterion you may need like companies using Salesforce or retailers in US with 20+ location and so on, which our process can deliver with easy. Lastly, the contacts you may need may not exist in a large subscription database and that severely limits your ability to target. With ReadyContacts, you can fine tune the contacts based on titles and title keywords.
ReadyContacts has been a great partner since we started ShippingEasy. We have found their leads to be higher quality than any other vendor we have tried. Their team is a pleasure to work with and always responsive.
