I have a 500-600 name Excel spreadsheet of prospects for an outbound email campaign. I have all email addresses, along with first and last name of recipients. I have multiple versions of an HTML responsive design that I want to split across my file for an A/B test. I want to send the email as an individual, not a blast campaign, using my Outlook platform. I need someone to conduct A/B test campaign using my Excel contact list and an established email address from my company account.
