Images in the subject line

I’ve seen this trick used by a few senders recently, with varying effectiveness.

Where do they get these pictures?
While you can scatter any images you like across the body of your message, the subject line is limited to just text. But “text” is more than just “a, b, c” – using RFC 2047 encoding you can use any character you like, including many tiny pictures.

Experian, Vertical Response and Bronto all have some interesting things to say about the effectiveness of using these.
Finding the right glyph can be tricky. Macs have a fairly decent glyph search engine (under Edit > Special Characters… in most applications) while Windows has a fairly mediocre one (Start > All Programs > Accessories > System Tools > Character Map > Advanced View). Both are missing some useful features, though, so I put together something better.
emailstuff.org/glyph lets you search for glyphs by name. It’ll tell you about related glyphs (“helicopter” and “airplane”, or “package” and “wrapped present”) which can help you find the right image when you don’t know it’s name. And, once you’ve chosen a glyph, it shows how to use it in various encodings (if you’re using a GUI tool or a web form to compose your emails you can probably just copy and paste, but it’s handy for manually editing messages when your composition tool isn’t unicode-friendly).
Will all your recipients be able to see these glyphs? All mail clients support utf-8 text and this sort of encoding so the only issue is whether the recipient has a font installed with the glyph in it. That’s operating system specific, rather than depending on the web browser or mail client, so if you want to test – and you probably should – you can get away with just Windows and OS X for desktop, iOS and Android for mobile.
Have fun! But don’t overdo it.

Meaningless metrics

I’ve been having some conversations with fellow delivery folks about metrics and delivery and bad practices. Sometimes, a sender will have what appear to be good metrics, but really aren’t getting them through any good practices. They’re managing to avoid the clear indicators of bad practices (complaints, SBL listings, blocks, etc), but only because the metrics aren’t good.
This made me laugh when a friend posted a link to a Business Insider article about how many website metrics aren’t useful indicators of the business value of a website.  Then I found the original blog post referenced in the article: Bullshit Metrics. It’s a great post, you should go read it.
I’d say the concluding paragraph has as much relevance to email marketing as to web marketing.

Phones part of SMS botnet

Spammers have been moving into the phone market for a long time. Just recently security firms have discovered an Android  botnet. This botnet sends viruses over SMS, and when a link in the SMS is clicked, the phone is infected with the virus which then sends more SMS.
The technology for blocking and reporting SMS spam is comparable to email blocking technology 10 or 12 years ago. There just aren’t many tools for people to use to control this spam. M3AAWG is addressing mobile spam, but it still seems that the volumes are increasing without much recourse. Even the 7726 reporting number doesn’t seem to stop the spam (nor remove per-text charges).
At least in the beginning of the email spam problem, we didn’t have botnets. Now, at the beginning of the curve for SMS spam, we already have self replicating botnets. I’m afraid the good guys might be behind on this issue.
Then again I might just be cranky because SMS spammers woke us up at 4:30 am.

There is no bat phone

I don’t have much to add to Al’s post about the lack of people to call at different ISPs to get mail delivered. I will say there was a time some ISPs had staff that would deal with senders and blocking problems. But those positions have gradually been eliminated over the last 2 or 3 years. In some cases the employees left for greener pastures, in others they were subject to layoffs and budget cuts. In most cases, though, the employees were not replaced.
ISPs have moved to complex and multi-tired spam filtering. They’ve removed the ability of most employees to actually interrupt the filtering and special case a sender. Getting mail delivered is about sending mail that recipients want. It’s not about who you know. It’s about how much recipients like your mail.

Troubleshooting tools

There have been a number of comments on my post about Hotmail moving to SPF authentication having to do with troubleshooting authentication failures. I have been helping clients troubleshoot these issues, and am able to take on new clients to solve authentication problems. Contact me for more information.
Of course, many of these issues can be solved with access to the right tools. Steve’s been working on a number of tools that may help the troubleshooting process and we’ve recently launched them on Emailstuff.org. The website itself contains a number of DNS and data related tools we use for investigations and thought we’d share with the public at large.
One of the really useful tools is the SPF record expander. Plug in any domain, like google.com, and see what IP addresses they authorize to send mail.

TWSD: Adapt to filters

This morning the new Yahoo! CEO posted about changes to Yahoo! mail. I logged into one of my Yahoo accounts to check and see if I had access to the new Yahoo! mail client yet. I don’t, but I did notice that spammers have adapted to the new Yahoo model of disabling filters in the mail folder. Most of the mail in my inbox has, at the very top of the message “Click not spam to enable links!”
My favorite has to be the animated gif of how to click “not spam.”
Spammers spend so much time and energy compensating for filters, hopping IP addresses, rotating through domains, and specially creating mail for different ISPs. I have to wonder, though, if they would waste less time by sending opt-in mail.
