For INBOX SMTP you should configure slow email sending speed. It is best to send emails at a rate of 5 seconds per email. Sending like this will not damage the Server. Do not kill SMTP.

INBOX SMTP is not the same as Unlimited SMTP Server (Source: Created). You should not send mass emails at high speed. That kills SMTP very quickly.

Guarantee: YES

Life time: forever
