I was learning about cold email marketing earlier this year, and it's all about learning to be a spammer:

- Registering lots of domains (launchmyapp.com, trymyapp.com, myapp.info, gomyapp.biz, etc.)

- setting up a limited number of mailboxes per domain

- warming email accounts up for 2 weeks by signing up for a service that sends to and receive messages from your accounts

- setting up a meta inbox to track messages sent and received across all of your accounts

Now pretty much every domain that isn't myapp.com looks like a spammer's domain to me.

You sound surprised. What's the difference between "cold email marketing" and "spamming"?
