How can I import email addresses of newsletter subscribers that I exported as a cvs file from my store prior to converting it to Magento? I'm using Magento 2.
You won't be able to import that list with Magento out-of-the-box but the database table is pretty simple.
Maybe you can try to subscribe 1 user and then export the values of the tables. Next step is to create a file with the same structure and all your values.
Finally, import the information into the database table.
Isn't too critical. I guess you haven't subscribers right now.
The best idea is to subscribe an account and then compare the values to fill the new lines.
