I connected my Sendinblue account by API key with Newsletter. What are the best settings? What to choose in the Enable dropmenu: Enable or Disable? And do I need a separate SMTP plugin or is the communication between Newsletter and Sendinblue sufficient?
Could you pleas answer my question. I have a Sendinblue account. They limit my send quota because Newsletter uses a SMTP connection instead of API.Is this a known problem and is there a solution?
