The perfect email

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.

Still futile

Guaranteed email delivery

Ben over at Mailchimp has a good post about his response (and his support staff’s more professional and helpful response) to inquires asking if Mailchimp can guarantee an improvement in delivery.
I sympathize with Ben, and commend his staff. I often get potential clients asking me if I can guarantee I can get their mail to the inbox or get them off a public or private blocklist. And, the answer really is no, I can’t guarantee anything. Much of delivery is solely in the hands of the actual sender. Sure, ESPs can enforce a certain standard of behaviour and they can do all the technical things right. And consultants like me can tell you how ISP spam filters work and explain how some of your choices and processes affect delivery. But none of us can guarantee inbox delivery.
Only one company has tried to guarantee inbox delivery, and they shut down earlier this year because they were non-viable and couldn’t get enough of a recipient userbase to attract customers.
For the rest of us, though, the best we can do is give senders the tools and information they need to succeed in getting mail delivered to the inbox.

SPF records: not really all that important

I’ve been working through some Hotmail issues with a client over the last few months. One of the things that has become clear to me is how little Hotmail actually does with SPF records. In fact, Hotmail completely ignored my client’s SPF record and continued to deliver email into the inbox.
This isn’t just a sender that had a “well, we think most of our email will come from these IPs but aren’t telling you to throw away email that doesn’t” record. In fact, this client specifically said “if email doesn’t come from this /28 range of email addresses, then it is unauthorized and should be thrown away.” The email was being sent from an IP outside of the range listed in the SPF record.
As part of the process involved in fixing the delivery problems, I had the client update their SPF record and then I enrolled their domain in the SenderID program at Hotmail. This didn’t have any effect, though. Hotmail is still not checking SPF for this client. When I asked Hotmail what was going on they said, “We do not do lookups on every sender’s mail.”
So, there you have it folks. The last bastion of SPF/SenderID has abandoned the technology. Even a totally invalid SPF record doesn’t matter, mail can still reach the inbox at Hotmail.
