Best time to send marketing email

Pages and pages have been written about the best time to send email. Marketers spend significant amounts of energy discussing and researching the best time of the day and the best day of the week to send email. I have long thought that these discussions do not put enough attention on individual end users and how the recipients interact with email.
Researchers recently developed a model for email user behaviour that splits email users into two classes “e-mailaholics” that send, and presumably read, email all the time and “day labourers” that send, and presumably read, email during standard business hours. There is very little transition between groups, 75% of users stayed in the same usage group over the 2 years of the study.
What does this mean for senders? Senders need to know know how their recipients use email and which user group recipients are. By analyzing clicks and opens, senders can classify recipients and use that data to send mail that is more relevant and better targeted.

Sending mail from unread email addresses

Some marketers, even large marketing companies, send mail from email addresses that are unread. Justin Premick posted a list of reasons this is a very, very bad idea. Be sure to read the comments, too.

Walking the Walk

Last week I mentioned a Smith-Harmon report about how to handle email when going out of business. I mentioned at the end of the post that I was pleasantly surprised at how well done their email program was. Let’s walk through the process.
1) The download process. Clicking on the “download report” page popped up a signup window. They ask for first name, last name, company and and email address, but only require an email address. There is a link to their privacy policy and two unchecked boxes. The first is “I would like to subscribe to Smith-Harmon’s monthly newsletter, which is full of email marketing tips, news and research.” The second is “Please have a representative contact me to discuss how Smith-Harmon can help my company with its email program.”
How does their process incorporate best practices?

TWSD: Run, hide and obfuscate

Spammers and spamming companies have elevated obfuscating their corporate identities to an artform. Some of the more dedicated, but just this side of legal, spammers set up 3 or 4 different front companies: one to sell advertising, one or more to actually send mail, one to get connectivity and one as a backup for when the first three fail. Because they use rotating domain names and IP addresses all hidden behind fake names or “privacy protection services”, the actual spammer can be impossible to track without court documents.
One example of this is Ken Magill’s ongoing series of reports about EmailAppenders.

Their actions, chronicled in his posts, are exactly what I see list providers, list brokers and “affiliate marketers” do every day. They hide, they lie, they cheat and they obfuscate. When someone finally decides to sue, they dissolve one company and start another. Every new article demonstrates what spammers do in order to stay one step ahead of their victims.
While Ken has chronicled one example of this, there are dozens of similar scammers. Many of them don’t have a persistent reporter documenting all the company changes, so normal due diligence searches fail to turn up any of the truth. Companies looking for affiliates or list sources often fall victim to scammers and spammers, and suffer delivery and reputation problems as a result.
Companies that insist on using list sellers, lead generation companies and affilates must protect themselves from these sorts of scammers. Due diligence can be a challenge, because of the many names, domains and businesses these companies hide behind. Those tasked with investigating affiliates, address sources or or mailing partners can use some of the same investigative techniques Ken did to identify potential problems.

The Weekend Effect

Sending mail only Monday through Friday can cause reputation and delivery problems at some ISPs, even when senders are doing everything right. This “weekend effect” is a consequence of how ISPs measure reputation over time.
Most ISPs calculating complaint rate use a simple calculation. They measure how many “this is spam” clicks a source IP generates in a 24 hour period. Then they divide that number by how many emails were delivered to the inbox in the same 24 hour period.
The weekend effect happens when a sender sends on weekdays and not on the weekend thus lowering the number of emails delivered to the to the inbox. Recipients, however, still read mail on the weekend, and they still hit the “this is spam” button on the email. Even if the number of “this is spam” clicks is lower than a normal weekday, with no incoming email the rate of spam complaints goes above ISP thresholds. Even a very well run mailing program may see spikes in complaint rate on the weekends.
Now, when the ISPs are measuring complaint rates over time, they take the average of the average complaint rates. If the rates spike high enough on the weekend (and they can spike to the 1 – 3% range, even for a well run list), that can hurt the senders’ reputation.
The good news is that ISPs are aware of the weekend effect and take this into account when manually looking at complaints. The bad news is that not all of the major ISPs take this into account when programatically calculating reputation.
There isn’t very much senders can do to combat the weekend effect, except be aware this can happen and may be responsible for poor mailing performances on Monday. If you are seeing delivery problems you think may be a result of the weekend effect you can contact the ISPs and ask for manual review of your reputation. Some ISPs can provide manual mitigation for senders with otherwise clean stats. d

Going out of business email strategies

Chad White of Smith-Harmon posted a report today on shutting down email marketing programs when going out of business. He looks in detail at how a number of companies handled their email marketing during the going-out-of-business process. There is a very solid mix of examples of how companies handle things. Some companies do things very badly, like never mention over email that they’re going out of business or neglect to follow CAN SPAM regulations. Others used their list as a communications tool that survived the dissolution of the parent company.
The full report is well worth a read, but the take home messages are clear.

How Spamfilters Work

AllSpammedUp has a post describing the primary techniques anti-spam filters use to identify mail as spam or not spam. While is this not sender or delivery focused knowledge, it is important for people sending mail to have a basic understanding of filtering mechanisms. Without that base knowledge, it’s difficult to troubleshoot problems and resolve issues.

Confirmed opt-in

I spent the morning in multiple venues correcting mis-understandings of confirmed opt-in. The misunderstandings weren’t so much that people didn’t understand how COI works, but more they didn’t understand all the implications.
In one venue, the conversation centered around how small a portion of deliverability the initial subscription process affects. Sure, sending unwanted, unexpected email can and does cause reputation problems, but merely using COI as a subscription methodolgy doesn’t automatically give a sender a good reputation or good delivery. Senders using COI as a subscription practice need to also need to send relevant and engaging mail that their recipients expect to receive. They need to handle their bounces well and purge or re-engage inactive subscribers. They need to keep their complaints low and their responses high.
How you manage subscriptions is only one factor in reputation schemes, and even if the subscription method is COI other factors can negate any bonus involved.
The second conversation involved Ken challenging me on the comment I left on his quiz yesterday. I said COI wasn’t foolproof and he challenged me to explain how. I did, and he’ll be following up next week.
