Project details
Is the conversion rate of your lead data is getting lower year over year? Is your B2B CRM database outdated? I am here to enrich your database by validating, cleaning, and appending new leads and help you to make your database up-to-date to grow your sales.
The key objective of the project is to research the leads and validate every data in the database record-by-record manually. The tedious work involves several processes.
1. Ensure your leads are validated or changed by researching the respective lead via open web search (Some leads may change their job titles within the same company), if so we will make necessary action to enrich the data by appending/validating the Email, Location Address, etc.
2. If your lead is moved to another company we will mark that record and gather new company details along with the emails.
3. Our eagle-eyed process involves finding and removing invalid leads say, Retired, Diseased, and Duplicate from the database.
4. Providing a valid point of contact is our utmost importance to achieve this we are using great tools to find and verify the emails.
5. We are ready to append new target leads along with emails and other data into the same database.
