Text to Image ratios in email

One of the questions I get from folks about delivery is what the optimal text to image ratio there should be in an email. I’ll be honest, I hate this question. Why? Because the question is actually irrelevant. I’ve seen companies with a single image and no text get to the inbox. I’ve seen companies with no images get to the inbox. The text to image ratio is not going to make or break delivery.
Sending mail that the user expects and wants is the crucial part of delivery. If the user wants a single image? That’s the right ratio. If the user wants a readable message with images turned off? That’s the right ratio. Fretting about 20/80 or 18.5/81.5 or 43.256666/56.743334 is getting buried in details and missing the bigger picture.

Emails should be readable. These days, being readable on mobile is critical. This is the single best argument I can think of against one-image emails. And there are still folks who read email with images off by default. Being one of them, I think it gives me insight other delivery folks lack. If I am engaged with a brand, how do I show it outside of loading images? What kinds of things let the brand know I’m still a happy recipient?
If anyone tells you that your delivery problems are the result of a bad text to image ratio, run away. There is zero chance that’s actually true. Filters aren’t going to just look at the ratio and block ratios that fall into a certain range.
What filters are going to do is take the text to image ratio as part of the fingerprint of an email stream. They’re going to recognize certain factors about emails that users like, and factors about emails that users don’t like. Some of these factors will be things like the text to image ratio. But the “wrong” ratio isn’t why mail is being filtered. Mail is being filtered because the recipients aren’t interacting with it enough and the ratio is just one part of the way the ISP identifies it.
Stop fretting over your exact text to image ratios. The right, or wrong, ratio isn’t a true factor in delivery. Instead, focus on creating an email stream that users want, expect, and engage with. This starts with address collection, but collecting accurate addresses isn’t enough. You also need to provide value to them.
Sending mail users want is the key to reach the inbox. Doing that takes time and investment by the sender.

Image Blocking

I received this email earlier this week, an email that I wanted but this is how it arrived.
email example 1
The email contained a single image link, a text line of who the message was sent to, the senders name, address, and finally an unsubscribe link.
Good news, the email is CAN-SPAM compliant! Bad news, I have no idea what the content of the message is and it looks somewhat spammy.  The email was sent to my Junk Folder and all images were blocked. As a good netcitizen, we’re trained not to click links if we’re not sure what they are.
Here is another message I received around that same time and also had the images blocked.  I immediately recognize the domain name, bowling.com and there is text that mentions bowling shoes, balls, and bags. Being an avid bowler, I wanted this message and I will be adding them to my safe senders list in Outlook.

The good news for marketers who rely on image based emails is Gmail and many mobile mail clients will auto-load images but there are still many clients that will only display images if the user sets the sender as a trusted sender.  If you are sending a Welcome Message, it’s best to include text along with your images so the recipient can recognize your email and will then add you as a trusted sender.  You can also segment your list by users who are opening the images. The recipients who have not loaded the images would get a different version of the message that includes more text.

Open subscription forms going away?

A few weeks ago, I got a call from a potential client. He was all angry and yelling because his ESP had kicked him off for spamming. “Only one person complained!! Do you know him? His name is Name. And I have signup data for him! He opted in! How can they kick me off for one complaint where I have opt-in data? Now they’re talking Spamhaus listings, Spamhaus can’t list me! I have opt-in data and IP addresses and everything.”
We talked briefly but decided that my involvement in this was not beneficial to either party. Not only do I know the complainant personally, I’ve also consulted with the ESP in question specifically to help them sort out their Spamhaus listings. I also know that if you run an open subscription form you are at risk for being a conduit for abuse.
This abuse is generally low level. A person might sign up someone else’s address in an effort to harass them. This is a problem for the victim, but doesn’t often result in any consequences for the sender. Last week’s SBL listings were a response to subscription abuse happening on a large scale.
