I use thenewsletterplugin.com for my wordpress.
Can you confirm that all the clients emails are not stored in the WP data base but directly on the DB of the newsletterplugin ?
Newsletter is a totally self-hosted solution and all the data resides on your hosting space only. Even the diagnostic data can be enabled only by.a specific optin. We have absolutely no access to your subscribers list and related info.
Hi, the import/export addon is free, you can download it from the account page on this site. If you need a full dump of the subscriber table, look for the table wp_newsletter (wp_ is a prefix, it can be different on your installation).
from time to time, we ask our users to rate Newsletter based on their experience: every feedback means the world for us. If you have 5 minutes, here’s the link: https://bit.ly/please-rate-newsletter. A wordpress.org account is required. Thank you!
