 * Hi [@summitwinterguard](https://wordpress.org/support/users/summitwinterguard/),
   
   thanks for reaching out.Send errors are errors returned by your email provider
   and/or hoster.More general info on that here: [https://wpmailster.com/doc/how-to-deal-with-send-errors/](https://wpmailster.com/doc/how-to-deal-with-send-errors/)
 * The specified reason is stated here:
 * _Message rejected due to content policy
   SMTP code: 550 Additional SMTP info: 
   5.7.0
 * Reasons could be: message size too large, too many BCC recipients, too many email
   per second/minute/hour, … many potential reasons.
 * You need to talk to them to find out what they don’t “like” about the message,
   and what they mean with the code 5.7.0
 * Hope that helps.
