Error "421 Resources temporarily unavailable - Please try again later." when sending emails
Here's what happens when you send emails through Kennel Connection.
When it's time to send the emails, KC logs into your email provider's server. Once the login information is authenticated, KC sends all of the emails to the server at once. This is all it does. It's up to your email provider to send the emails to your clients.
This error means the email smtp server KC is trying to connect to is unavailable or is rejecting the connection.
KC has no ability to block or reject this connection. You will need to contact your email provider to address the issue.
