You cannot send the same email twice – different list

Hi @solarian-ian,

Yes, because it could be considered spam.

If you want to test your newsletters before sending it, you could use the Preview Panel: https://beta.docs.mailpoet.com/article/143-the-newsletter-designer

right… Thank you for pointing out Preview Panel, I already used it when tested with single email address. However, a test email list could be handy for people when multiple persons (like 3 or 4) must see & aprove the test before real sending.
