Hello,
I have a csv dump which only has email addresses, no other fields, I have added another column to the spreadsheet called ‘Exclude’ and I have updated this field to ‘Yes’ for all the email addresses I have. I have also created a field called Exclude in CRM.
Ideally I want to import the Exclude column only into CRM and update only those contact records where the email address appears on my csv file. Does anybody know how using the out of box import tool to match the contact record based on email address (which is the only information that I have) and update only the Exclude field on the existing contact record. So basically I am not trying to create a new contact record but rather update the Exclude field on existing contact records and the only unique identifier I have is the email address.
Any pointers in the right direction would be great.
Thanks
JazB
