When to include a physical address

One of the requirements to be CAN-SPAM compliant is to include a physical address within every promotional email that is sent. If your company hires a third party to send email on your behalf, your physical address should be clearly visible within the message when the message is selling your products and services. There is a stipulation that if your message is transactional or a relationship message, then it does not need to adhere to the CAN-SPAM requirements by including your physical address or unsubscribe link.
Examples of transactional mail would be welcome emails, password resets, auto-responders, shipment notifications, or account alerts.  While you and I may know that these emails aren’t required to include this information most users would not know.
street-signsThe CAN-SPAM Act has been in effect going on 12 years and recipients look for unsubscribe links and physical addresses within the messages. Emails that are missing this bit of information leads the recipient to believing the message is spam.  While including the physical address and unsubscribe link are not required for your transactional emails, it’s better to be safe than sorry and include them anyways.
The recipient may have recently received a series of marketing emails from you and when they receive a transactional mail message, they may want to adjust the frequency of the mail they are receiving. By not including an unsubscribe link and physical address, the user may resort to marking the message as spam.
When sending marketing and transactional emails, you want to adhere to the law and then take the user behavior and expectations into consideration. There is no harm in including your physical address in both your marketing emails and transactional emails.

Put a fork in it

When FB messaging was announced email marketers had a total conniption. There were blog posts written about how FB Messaging was going to kill email as we know it.
Now, slightly more than a year later marketers have declared FB Messaging dead.
Sometimes I think people spend way to much time believing their own press. FB messaging was never designed as a marketing platform. I said as much back in November 2010 when it was announced.

The Physics of the Email Universe

We talk a lot about rules and best practices in email, but we’re mostly talking about “squishy” rules-of-thumb that are based on simplified models of how mail systems, spam filters, recipients, postmasters and blacklist operators behave. They’re the biology, ecology and sociology of the email ecosystem.
There’s another set of rules we tend to only mention in passing, if at all, though. They’re the steely, sharp-edged laws that control the email universe. They’re the RFCs that define how email works and make sure that mail systems written by hundreds of different people across the globe all work and all interoperate with each other.
Building a message from Zeros and Ones
RFC 5322 – Internet Message Format
This tells you everything you need to know about crafting a simple email, with a subject line, a sender, some recipients and a simple plain-text message. It’s also the foundation of all fancier emails. If you’re creating emails, this is where to start.
A little more than plain ASCII
RFC 2047 – MIME Part 3: Message Header Extensions for Non-ASCII Text
RFC 2047 is one small part of the MIME (Multipurpose Internet Mail Extensions) suite of protocols that allow you to include pictures and attachments and prettily formatted text and comic sans in your email. This part defines how you can put things other than the plainest of plain text in your subject lines or in the “friendly from” of your message. It’s what allows you to put Hiragana, or Cyrillic, or umlauts, or cedillas, or properly matched double quotes in your subject line. It also let’s you put hearts or smiley faces or other little pictograms there – but nothing this useful is going to be perfect.
RFC 2045 – MIME Part 1: Format of Internet Message Bodies
This shows how to send an image, or a plain text mail in a different character set, or an HTML mail. It doesn’t tell you how to send plain text and HTML, or to send HTML with embedded images, or a message with an attached document. For that you need…
Finally, Modern Email
RFC 2046 – MIME Part 2: Media Types
This builds on RFC 2045 to allow you to have many different chunks in a message – this is what you need if you want to send “proper” HTML mail with a plain text alternative, or if you want embedded images or attachments.
Getting From A To B
RFC 5321 – Simple Mail Transfer Protocol
A message isn’t much use unless you send it somewhere. RFC 5321 explains the mysteries of actually sending that message over the wire to the recipient. If you need to know about the different phases of a message delivery, what “4xx” and “5xx” actually mean, why there’s not really any such thing as a hard or soft bounce defined, just temporary or permanent failures, or anything else about actually sending mail or diagnosing mail delivery, this is your starting point.
The Rest Of The Iceberg
I’ve only touched on the very smallest tip of the email iceberg here. There’s much, much more – both in RFCs and ad-hoc non-RFC standards. If you’re interested in more, this is a decent place to start.

September 2014: The Month in Email

September was another busy month for us, but Steve stepped up and wrote a number of really interesting posts on email history, cryptography, and current technical issues in the email landscape.
We started the month with a look at the various RFCs that served as the technical specifications for developing message transfer protocols in the 1970s. It’s really fascinating to look at the evolution of these tools we use every day 40 years later. We followed up with a second post on the origins of network email, which is a great primer (or refresher) on the early days of email.
Steve’s four-part series on cryptography and email started with an in-depth look at how the industry is evolving with respect to encryption and privacy issues. He then introduced us to Alice and Bob (or reintroduced those of us who have been following the adventures of the first couple of cryptography), and described symmetric-key and public-key encryption. His next post described message signing, and how DKIM is used to manage this. He finished up the series with a post on PGP keys.
In industry news: Spamcop is shutting down its email service. There shouldn’t be any major impact on senders, but the post has some specific notes on DMARC implications. We also noted an interesting mail routing suggestion on Twitter, and wrote a post on using Mail.app for this.
In other DMARC news, we wrote about DMARC and report size limits, which might be useful information, depending on your configuration. We also launched a new DMARC tool to help senders understand who is publishing DMARC. Let us know what you think and if you’re finding it useful.
We couldn’t let a month go by without mentioning filters. We looked at a sector we don’t usually discuss, corporate filtering, and went in-depth on a much-misunderstood topic, content filtering.
Finally, Laura offered a webinar on a favorite topic, deliverability, in conjunction with the AMA and Message Systems. If you missed it, you can watch the recorded version here, or just take a peek at some of the reaction via Twitter.
