May 2016: The Month in Email

Summer, already? Happy June! Here’s a look at our busy month of May.
201605Wrapup
I had a wonderful time in Atlanta at the Salesforce Connections 2016 conference, where I spoke on a panel about deliverability. While in Atlanta, I also visited our friends at Mailchimp, and later spoke at the Email Innovations conference in Las Vegas, where I did my best to avoid “explaining all the things”. Since my speaking schedule for 2017 is filling up already, I’m sure I’ll have plenty of opportunity to explain many more of the things over the next year or so. Let me know if there’s an event that might be a good fit for me, either as a keynote speaker or on a panel.
Steve contributed a few technical posts on the blog this month. He mentioned that Google has stopped supporting the obsolete SSLv3 and RC4, and he explored the ARC protocol, which is in development and review, and which will be useful in extending authentication through the email forwarding process.
Meri contributed to the blog this month as well, with a post on the Sanders campaign mailing list signup process. We’ve written about best practices for political campaigns before, and it’s always interesting to see what candidates are doing correctly and incorrectly with gathering addresses and reaching out to supporters.
In other best practices coverage, I pointed to some advice for marketers about authentication that I’d written up for the Only Influencers list, a really valuable community for email marketers. I wrote about purchased lists again (here’s a handy collection of all of my posts on the topic, just in case you need to convince a colleague that this isn’t a great idea). I also wrote about how getting the technical bits right isn’t always sufficient, which is also something I’ve written about previously. I also discussed the myth of using the word “free” in the subject line. As I said in the post, “Single words in the subject line don’t hurt your delivery, despite many, many, many blog posts out there saying they do. Filters just don’t work that way. They maybe, sorta, kinda used to, but we’ve gotten way past that now.”
On a personal note, I reminisced about the early days of mailing list culture and remembered a dear online friend as I explained some of why I care so much about email.
In my Ask Laura column, I covered CAN SPAM and transactional opt-outs. As always, if you have a general question about deliverability that I can answer in the column, please let me know.

PTR Records

PTR records are easy to over look and they have a significant impact on your ability to deliver mail without them.  Some ISP and mailbox providers will reject mail from IP addresses that do not have a PTR record created. PTR records are a type of DNS record that resolves an IP address to a fully qualified domain name or FQDN.  The PTR records are also called Reverse DNS records. If you are sending mail on a shared IP address, you’ll want to check to make sure the PTR record is setup, however you most likely will not be able to change it.  If you are on a dedicated IP address or using a hosting provider like Rackspace or Amazon AWS, you’ll want to create or change the PTR records to reflect your domain name.
We usually think about DNS records resolving a domain name such as www.wordtothewise.com to an IP address.  A query for www.wordtothewise.com is sent to a DNS server and the server checks for a matching record and returns the IP address of 184.105.179.167.  The A record for www is stored within the zone file for wordtothewise.com.  PTR records are not stored within your domain zonefile, they are stored in a zonefile usually managed by your service provider or network provider.
Some service providers provide an interface where you can create the PTR record yourself, others require you to submit a support request to create or change the PTR record.
If you know what IP address you are sending mail from, use our web based DNS tool to check if you have a PTR record created.
http://tools.wordtothewise.com/dns
Checking for a PTR record for 184.105.179.167 returns
167.128-25.179.105.184.in-addr.arpa 3600 PTR webprod.wordtothewise.com.
If you received Response: NXDOMAIN (There is no record of any type for x.x.x.x.in-addr.arpa), this means you’re missing the PTR record and need to create one ASAP if you are sending mail from that IP address!

The perfect email

More and more I’m moving away from consulting on technical setup issues as the solution to delivery problems. Delivery is not about the technical perfection of a message. Spammers get the technical right all the time. No, instead, delivery is about sending messages the user wants. While looking for something on the blog I found an old post from 2011 that’s still relevant today. In fact, I’d say it’s even more relevant today than it was when I wrote it 5 years ago.

Email is a fluid and ever changing landscape of things to do and not do.
Over the years my clients have frequently asked me to look at their technical setup and make sure that how they send mail complies with best practices. Previously, this was a good way to improve delivery. Spamware was pretty sloppy and blocking for somewhat minor technical problems was a great way to block a lot of spam.
More recently filter maintainers have been able to look at more than simple technical issues. They can identify how a recipient interacts with the mail. They can look at broad patterns, including scanning the webpages an email links to.
In short, email filters are very sophisticated and really do measure “wanted” versus “unwanted” down to the individual subscriber levels.
I will happily do technology audits for clients. But getting the technology right isn’t sufficient to get good delivery. What you really need to consider is: am I sending email that the recipient wants? You can absolutely get away with sloppy technology and have great inbox delivery as long as you are actually sending mail your recipients want to receive.
The perfect email is no longer measured in how perfectly correct the technology is. The perfect email is now measured by how perfect it is for the recipient.
