Originally from ticket #12207.
Constant contact will only accept emails in the following formats: .xls,.xlsx,.csv,or .txt
None of these are options that I am able to find on your virtuoso. TAB,PDF,tsv
It is essential that I market to the 1000+ emails on my website and over 5000 on constant contact.
The csv tab or tsv files are text files and should work with constant contact. You might need to change the filename to .txt if constant contact is not able to recognize it.
One good way to get the emails you need is to create a custom report. I created a couple for you to use, or as examples, under Reporting/Custom.
Click the csv option and the text file is created. You could open these with excel if you want to check them, and then just save as an excel file for Constant Contact.
