One of the most frustrating things for commercial and volume email senders is that different ISPs have different standards for what they require in order to ensure that your email gets delivered. On top of that, many ISPs don't seem to adhere to the agreed industry standards in terms of how their receiving mail servers interact with the sending mail servers - for example five different ISPs may use five different SMTP error codes when they bounce an email because the email address doesn't exist, even though people believe there to be one generally accepted code for that situation (along the lines of "550 user unknown").
Address book importing. Odds are good that if you aren't doing it, you are either thinking about doing it, or you know someone who is doing it or thinking about doing it. Because, you see, it's all the rage. It's also an awful practice.
You should never send mass or bulk email through a new IP address before you warm up that new IP address. Warming up an IP address is a critical step towards not only having good deliverability, but also to making sure that your email isn't tagged as spam, or blocked.

Exactly what is a CAN-SPAM physical address? The CAN-SPAM Act, which is the U.S.' Federal email marketing law, requires that you include your physical mailing address in each and every bulk mailing, such as an email newsletter, email marketing, or other email to a mailing list. For some reason this requirement confuses people - maybe because it's so straight-forward, and people are used to complex, convoluted, and contradictory (the Three Cs of legislative drafting) language when it comes to the law.

It's hard to believe as we are closing in on 2023 that there are still email marketers and other bulk email senders who don't immediately remove people who unsubscribe from their list, but it's true. So this article is for those people who need to understand that you really really need to remove the email addresses of people who want to opt-out from your mailing lists as soon as humanly possible.

Just mention the term 'DNS', and many email senders' eyes glaze over; say "reverse DNS" or "rDNS" and a look of panic may replace the glaze.
