Sending a test email failed with an error "550.5.7.509 Access Denied", what should I do next?

You can make slight modifications to the domain name, such as changing a letter, for example, use apple.con or amaz0n.com instead of apple.com or amazon.com, to ensure the domain does not match any verified domains.

I am receiving a "421 4.7.0 Not allowed" error while sending an email campaign. What does it mean?

This error occurs when SMTP server tries to open more connections than allowed in a given period. There are two solutions.

1. Increase the sending limit: You can adjust your mail server settings to allow more connections. Following are the recommended settings.

   • Number of connections in 30 minutes: 100

   • Number of emails per connection: 200

2. Retry the campaign : If you don't want to change server settings, retry sending your email campaign until all emails are delivered.
