Otherwise, you are faced with these terrible limitations:

• Emails can be sent only to and from verified email addresses.

• You can send a maximum of 200 messages per day.

• You can send a maximum of one message per second.

It’s unfortunate that users don’t get a warning when they signed up for the service, explaining about these limitations.
