Incoming email limit for a non-existing mailbox:

There is a soft-limit for the maximum number of emails sent to a non-existing mailbox, a domain can accept.
 
Rate limit: 500 emails/hour and 1000 emails/day
 
Once the rate is exceeded, the domain won't be able to accept any mail to a non-existing email address, however, the incoming email to the actual email won't get impacted until the domain/email rate limit defined earlier.
For a mass emailing solution, we recommend using Constant Contact and Sendgrid for your emails.
