 * Hi,
 * I have an error showing in plugin dashboard saying :
 * Error
 * Mailer : Sendinblue
    Problem : Subject is required
 * I think it happened when someone tried to retrieve his password (I use S2member).
   But when I send an email test, the message disappears.
 * Can you explain me what does that mean ?
 * Thanks a lot !

 * Hi [@contentologue](https://wordpress.org/support/users/contentologue/),
 * The issue looks like with the email being sent with empty Subject. Please check
   if the email sent from S2member has a properly formatted subject.
 * Thanks!

 * Thank you for your answer.
 * Yes, the plugin always has subjects for any email (registration, etc).
 * Curiously, this problem happened only once and never occured again…
 * Could it be caused by something else ?
 * Thank you !

 * Hi [@contentologue](https://wordpress.org/support/users/contentologue/),
 * the error message you got is quite clear: “Subject is required”. WP tried to 
   send an email, but the subject was for some reason not defined.
 * Maybe this was a glitch and it won’t happen again. If it does, it would be great
   if you could pinpoint the email that is causing it. This would allow us to debug
   and help you fix the issue.
 * These email delivery errors are displaying in your admin dashboard as long as
   the next email is successfully delivered. So your test email was successful and“
   deleted” the error notice.
 * Have a nice day!

 * If it’s happening again, I will see with S2member to get which email could cause
   this.
 * Thank you !
