Pete and Repeat were on a boat. Pete fell out, who was left?
I was searching the blog for some resources today and these were the first two posts that showed up on the search results. I often feel like I’m repeating myself, but sometimes I am.
Many of us are so used to email appearing instantaneous, we forget that the underlying protocol was never designed for instant messaging. When the SMTP protocol was originally proposed it was designed to support servers that may have had intermittent connectivity. The protocol allowed for email to be spooled to disk and then sent when resources were available. In fact, almost everyone who was around more than 10 years ago knows of a case where an email took weeks, months or even years to deliver.
These days we’re spoiled. We expect the email we send to friends and relatives to show up in their mailbox within moments of sending it. We expect that sales receipt or e-ticket to show up in our mailbox within instants of a purchase. We expect that our ISPs will get us email immediately, if not sooner.
But there are a lot of things that can slow down email delivery. At several points in the process an email may be spooled to disk. It stays on the spool until the next part of the delivery process can happen. Other points of slowdown include the various anti-spam, anti-virus and anti-phishing protections that ISPs must implement. Then add in the extreme volume of email (around 10 billion messages a day) and all of a sudden email delivery is slower than many senders and recipients expect it to be. This delay is not ideal, but the system is designed so that mail is not silently discarded.
While individual emails may be delayed, most users will rarely see that delay in the email that they send. Bulk senders, who may be sending thousands or hundreds of thousands of emails a day, may see more delays in a single send than the average user sees in years of sending one-to-one email.
Email is store and forward, not instant. Sometimes that means there is a delay in getting email into the recipients inbox. And, sometimes there isn’t anything anyone can do to speed up delivery, except to adjust expectations of how email works.
There is a persistent belief among some senders that the technical part of sending email is the most important part of delivery. They think that by tweaking things around the edges, like changing their rate limiting and refining bounce handling, their email will magically end up in the inbox.
This is a gross misunderstanding of the reasons for bulk foldering and blocking by the ISPs. Yes, technical behaviour does count and senders will find it harder to deliver mail if they are doing something grossly wrong. In my experience, though, most technical issues are not sufficient to cause major delivery problems.
On the other hand, senders can do everything technically perfect, from rate limiting to bounce handling to handling feedback loops through authentication and offer wording and still have delivery problems. Why? Sending unwanted mail trumps technical perfection. If no one wants the email mail then there will be delivery problems.
Now, I’ve certainly dealt with clients who had some minor engagement issues and the bulk of their delivery problems were technical in nature. Fix the technical problems and make some adjustments to the email and mail gets to the inbox. But with senders who are sending unwanted email the only way to fix delivery problems is to figure out what recipients want and then send mail meeting those needs.
Persistent delivery problems cannot be fixed by tweaking technical settings.
This summer’s non-work project for me has been training for a 5K run with Fleet Feet in Menlo Park. As part of the training programs we get weekly emails from the store on Monday. As I was reading through today’s email, I found myself smiling and happy. Lisa, who is one of the store owners and writes the emails, is just so happy and bouncy and thrilled to share her love of running and that comes through in the newsletter.
Our group’s primary coach is the other store owner. During runs we often talk about random stuff, and when I tell people I do email delivery, they always start talking about their experience with email and spam. One night I was running with Jim, and we were talking about Jim’s experiences with sending email. He mentioned their ESP and talked about how convenient it was. But then he mentioned he wasn’t sure that they were sending enough mail (which made me laugh hard enough I almost tripped on a curb).
I realized I am not just a delivery expert when I started thinking about all the ways they could increase the amount of email they send, while still maintaining the quality and the friendly feel of their bulk emails. What could they offer local runners that would increase the value of the store to them? The first very obvious thing was a race calendar. There are dozens of local races every week, telling folks about upcoming races and entry deadlines would be a way to contact folks regularly without it always being a “buy stuff from us!!”
What commercial emails have you gotten recently that have made you smile?
