Just a quick note that we’ve updated the TOS, specifically adding the bolded line:
You agree to not use the Service to send junk mail, spam, mailing list emails, or any other forms of unsolicited emails, and to not send emails for the purposes of advertising, phishing, spreading malware or viruses, or domain reputation warming (sending emails for the purpose of increasing your domain’s sender reputation). We reserve the right to immediately suspend any account found sending these types of email.
Email warming usually involves sending huge numbers of automated emails from a domain you control to another domain you control to “warm it up”, as a prelude for a marketing or advertising campaign. This is done so that you can start sending a large volume of emails from that domain without it ending up in spam.
Our reasoning is that email warming is: - Not what the service is intended for. - Actually even kind of abusive if you sign up for an account and then rapidly run a load warmup on simple plan pricing. - Can cause lots of load delivering fake messages. - A prelude to spammy marketing campaigns, which are against the TOS. - Possibly laundering Purelymail’s reputation in some way to abuse for yourself; I’m not sure it actually hurts our reputation, but it doesn’t sniff right.
