Malicious email terms defined.

Legitimate mailers need to distinguish themselves from spammers. One important piece of that is knowing what spammers do. SendGrid has put together some information on common scams and techniques spammers use to get email delivered. Some of these terms, like doxxing and swatting, are not specifically email related.

Responding to complaints

I sent in a complaint to an ESP earlier today. This was mail from a major UK retailer to an address that is not used to sign up for mail. It’s part of an ongoing stream of spam related to UK services and products. I believe most of this is because one of the data […]
