Earlier this month I attended the Email Evolution Conference in New Orleans for the second year. It was a great event with hundreds of marketers and featuring excellent content, particularly in the Technology and Deliverability track. In addition to the content, listening to the questions asked by marketers during these sessions really helped to illustrate some of the common challenges seen on the sender side.
One particular question that stuck in my mind was regarding transactional messaging. Following a raised hand was a statement to the effect of, “All the best practices on the web are for marketing messages. What about transactional mail? Where are the best practices for that?”
As email experts we often tout separating transactional email from marketing mail, but we don’t often provide tips for optimizing those transactional emails. Today we intend to make that right with 3 key tips on managing your transactional emails.
1. Determine if the mail is truly transactional
The definition of a “transactional” message is likely to vary depending on who’s answering. There are many definitions of transactional – some senders consider anything sent to a member to be transactional, while others strictly limit the category to things like receipts and shipping notices. In their CAN-SPAM Compliance Guide, the US Federal Trade Commission describes a transactional message as one that:
- facilitates or confirms a commercial transaction that the recipient already has agreed to;
- gives warranty, recall, safety, or security information about a product or service;
- gives information about a change in terms or features or account balance information regarding a membership, subscription, account, loan or other ongoing commercial relationship;
- provides information about an employment relationship or employee benefits; or
- delivers goods or services as part of a transaction that the recipient already has agreed to.
All of these types of messages require the recipient to have some sort of commercial transaction with the recipient – either a purchase or membership, but beyond that the waters can get a bit murky. The general consensus is that things like membership renewal notices, legally required notifications, and purchase receipts are considered transactional.
As a side note: if you’re sending to or from Canada, the Canadian Anti-Spam Law’s rules on transactional or relationship messaging are similar to those imposed under CAN-SPAM.
2. Stick to the 80/20 rule
To avoid issues when sending transactional messaging, you always want to be sure the primary purpose of the message is transactional in nature. While the definition of “primary purpose” is subject to some legal interpretation, the most commonly cited guideline is known as the 80/20 rule. This rule indicates that no more than 20% of a given message’s content should be promotional, with 80% or more transactional in nature.
In addition, most email professionals employ the less-scientific “sniff test” to determine if a message is transactional. This test looks at the most prominent elements of the message: subject line, preheader, the content presented first in the message body. If any of these elements is promotional in nature, the message would likely fail the “primary purpose” test. As a good rule of thumb, any promotional content should be presented below the transactional content of each message and should not be the focal point of the email.
In Canada, however, the 80/20 rule is not as relevant. Any amount of promotional content in a message may render it a “Commercial Electronic Message” and likely subject to the consent requirements of CASL. If you’re sending to or from Canada, we suggest avoiding any promotional content in your transactional messages unless you’ve consulted your legal counsel on potential implications.
3. Employ total separation between promotional and transactional streams
You’ll often hear a recommendation to have transactional (and other high-value relationship) messages sent from a separate IP address from your promotional or marketing emails. In theory, this separation prevents any potential issues with marketing emails (spam complaints, high bounce rates) from impacting the highly valuable transactional stream, which typically sees very high engagement and low complaints. However, best practices dictate going even farther and using separate subdomains for each stream.
With the impending flood of IPv6 IP addresses, major mailbox providers are relying more and more on domain reputation. If your transactional and promotional mail streams all originate from yourdomain.com, the reputation of the two streams will intermingle. One of the best ways to manage sending domains is to leave the top-level domain yourdomain.com for your corporate mail system, then use subdomains like promo.yourdomain.com and transaction.yourdomain.com for your marketing and transactional streams, respectively. This will help insulate your transactional traffic from any delivery speed bumps that might occur with your promotional sends.
Transactional emails can be a vital tool for maintaining customer loyalty and consistently see among the highest engagement rates of any email stream. They are also often underutilized.
