When is REALLY the best day to send out e-mail newsletters?

There are so many recommendations and statistics floating around about which day is the best to send out our e-mail newsletter.

We dedided to talk to communications specialist Tomas Kruse, who agreed to share his experiences about the subject.

Here’s his opening svada!

– You can stick those where the sun don’t shine along with the daily horoscope and other over-simplifying “facts”. Working out the best weekday and time for an e-mail newsletter is hard work with your own data, and not something you can learn from other peoples experiences. What you CAN learn from those experiences though is how and what to test, and not getting lazy when you think you’ve found the answer. But first and foremost, get to know your audience.

Which day do YOU think it’s best to put out your newsletter?

– It really depends on the segment. A good newsletter would be personalized as much as humanly possible to the reciever, and different segments will have different life-rythms, which means that the best time for THEM to recieve my newsletter also differ. But if you put a gun to my head and ask for one single answer, I’d say tuesday around 11.45 AM. Why? The work-week is well underway, lunchbreak is coming up and more people have time to actually read your message.

Is there anything special you should look for in your data besides days and times?

– As in all data mining you should be looking for general trends in your population. You might not have a lot of information on your subscribers, so a place to start out is to figure out if they are private or corporate. Private would be Outloook/Hotmail, Gmail, AOL and such, and corporate would be anybody with a company address. In my experience “privates” should recieve e-mails on evenings or weekends, while corporate should be contacted during working hours, not too early and not too late. And then, if for example you know their age, there will be diffences between young and old and so on. But really this is nitpicking and something you should only care about, when you master the basics: Really tight subject lines with a strong CTA and relevant (individualized) content.

What’s the status with HTML and text-only e-mail newsletters these days?

– Hubspot posted a study recently that I completely agree with. HTML e-mails are gaining grounds, but you should still keep the amount of HTML to a minimum. I can recommend reading their post: http://blog.hubspot.com/marketing/plain-text-vs-html-emails-data

Do you have any tips to connecting your e-mail marketing with social?

– First of all, do it! The more you can connect user data from different platforms, the better you can serve the right content to your users. I urge you to collect, connect and use data to increase relevance, but rather than pretending to be an e-mail/SoMe connection expert I’ll leave you with the advice of smartinsights.com, which pretty much sums up my thoughts: http://www.smartinsights.com/traffic-building-strategy/integrated-marketing-communications/connected-email-and-social/

Which is your favourite newsletter (headlines, content, frequency, technical, value)?

– Can I pick only one favourite? I like What We’re Reading (http://www.nytimes.com/newsletters/what-were-reading) from NYT for general news of the World, Cook Smarts for my foodie-fetish (http://www.cooksmarts.com/sign-up/we-believe-in-empowering-home-cooks/), The newsletter of Human Rights Watch for being newsletter industry leader in my current area of work (https://www.hrw.org/), and TED is just awesome in its whole scope (http://www.ted.com/newsletter). But as an eye and copy candy addictive, I think I love the HTML-overloaded newsletter from The Cool Hunter the most (http://www.thecoolhunter.net/subscribe).
