How Rasket stops abuse

What every sender goes through

• New accounts start small. For its first 24 hours an account can send at most 100 emails an hour and 500 a day. For the rest of its first week the limit grows with each day it sends cleanly.

• Phishing is refused, not sent. In an account's first week, mail that impersonates a known brand and asks for a password, or puts a brand in its From name that its own domain does not carry, is refused before it goes out.

• New and look-alike domains are screened. A sending domain registered in the last 30 days, or one shaped like a well-known brand, is flagged when it is added, and everything it sends meets the same checks.

• First campaigns are checked before they send. A new account's campaign is checked against the same lines before its first message goes out, and one that crosses them is stopped.

• Repeat offenders lose sending on their own. Every refused message counts against the account, so one that keeps trying moves down the ladder below without anyone having to step in.

Automatic pausing

We measure every account's bounces and spam complaints as mail is delivered. When either crosses a line, the account is warned, limited or suspended on its own, without waiting for a person.

What may and may not be sent is in our Acceptable Use Policy.
