without pause this is our concrete policy.
This should go without saying, but we'll say it anyway: it's not OK to spam people. If you try, we will immediately close your account. You will not get any refund.
Chances are, you already knew spam is bad. And as an email recipient, you know it when you see it.
It's important that as a sender, you know what spam is, too. We'd hate to see you make the mistake of spamming anyone with your email marketing campaign.
Ask people that question, and you'll probably get 10 different answers.
Email senders tend to use the textbook definition: Unsolicited Bulk Email (UBE). You can read more about this definition at Spamhaus.
UBE is a useful definition: it points out that some things that might be OK to do on a 1-to-1 basis (like send an email about your company to someone who has never heard of you) are not OK to do in bulk.
But it's not a perfect one. Many things are not UBE but are considered spam by most people, including us.
Instead of trying to create a definition of spam that covers every possible scenario, let's look at a few things that we will consider spamming. We think this will give you a pretty good idea of what not to do.
