I am currently running into the problem that it is impossible to import / update a CSV list of subscribers that is larger than 5.000 entries. The import always stops at approximately 5.000 and doesn’t continue. (Maybe a timeout?)
We are exporting our user data from our database in CSV format to import new users and update (overwrite) the info of existing users before we send out each newsletter. Now that we have a large number of subscribers we are running into issues.
Is there a fix or workaround for importing such a large number or subscribers?
Thanks in advance!
