Hi,
I have an Excel list of just over 26,000 contacts. Its about 6-7 years old.
I would like it cleaned of duplicates, dead email addresses, etc. so it can be used with limited or no bounces.
It has the similar data columns you would expect: First Name, Last Name, Address, Company Name, and Email Address.
This will be used for emailing so only the email address needs to be verified.
Thanks!
