We're truly disappointed to hear that you became frustrated and haven't yet achieved the results that you need.
At DealSignal, we are committed to customer success and currently maintain a 96% customer retention rate. We provide onboarding and customer support to help customers get started with their use cases, setup optimal criteria, and connect & integrate their CRM integrations, along with Q&A. Given the topic or issue, we involve whomever it takes to improve the customer experience - be it customer support, operations, engineering or one of our founders (who is still the chief product officer).
With regard to the criteria, we understand your challenge and appreciate your feedback. With more than 10 precision filters on Accounts and Contacts, there more than a few filters from which to choose, and perfecting your Target Buyer Persona Criteria and Target Customer Criteria can be challenging initially, and in certain industries it may require some trial, error and iteration to nail the precision and yet maintain the volume. Please note, we are always here to help provide suggestions or a quick consultation when the persona and account criteria aren't giving you the results you expected. Please contact us via chat, email, phone or request a zoom meeting to get help, and we will be there for you.
In our Enrichment module, we support CSV files and provide help text to show how to setup column headers in the CSV to upload files. It's important to match on the correct columns to achieve high match rates that our users need. And again, we're always here to support you, and help you with any issue that can come up.
