Subject Lines
Can we put the FREE!!! Myth to bed?
Really. Single words in the subject line don’t hurt your delivery, despite many, many, many blog posts out there saying they do. Filters just don’t work that way. They maybe, sorta, kinda used to, but we’ve gotten way past that now.
In fact, I can prove it. Recently I received an email from Blizzard. The subject line:
Laura — Last Chance to Claim Your FREE Copy of Warlords of Draenor — Including Level 90 Boost! Offer Expires Monday! Last Chance to Claim Your FREE Copy of Warlords of Draenor — Including Level 90 Boost! Offer Ends Monday!

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.

Subject lines
There has been a lot of discussion in various places recently about subject line length and how it affects email marketing. There have been multiple studies done on how the subject line affects opens and clicks. (Mailchimp, Alchemy Worx, Mailer Mailer, Adestra). The discussion has even spilled over into Ken Magill’s newsletter today.
I’ve had a couple people ask me my opinion on subject line over the years. My general response is that subject line length is not directly measured by spamfilters and so don’t fret about the length. It is true that consistently crafting poor subject lines can indirectly cause delivery problems. Send mail few people open and that will hurt your reputation over time.
I think Ken really said it best, though.
