Email mosaics by Email on Acid

Today, ISPs block a lot of the images in your email marketing campaigns. That’s not anything new. But what is new is the soon-to-be realistic use of mosaics in your emails. What are mosaicsMosaics are complex HTML tables that impersonate images. How can a table impersonate an image? The HTML table has so many rows and columns, each cell having a background color, that it can really look like an image. And above when I say “what is new”, I don’t mean brand new like the new baby ficus tree that Loraine in the cube next to me bought to replace the last one that she killed after throwing it at me.

Creating mosaics just got a lot easier

Mosaics themselves aren’t new. But compared to how difficult it used to be to create one, a new tool called Mozify coming from Email on Acid will make creating mosaics a lot easier. You see, in the past, to realistically create one that actually looked like an image took forever and was a giant pain in the (insert expletive here). So why would you use a mosaic in the first place? Well it’s a bit like slipping images into your email campaign and always having them displayed even if images are turned off. Since the mosaic isn’t really an image, the ISP doesn’t notice it. But your recipients sure do. In Mozify beta testing, one company saw a 346% increase in click throughs. So why do I think using mosaics is going to become a bad idea? Because mosaics will be blocked from email marketing campaigns in the near future.

Why would mosaics be blocked from email campaigns?

To understand my point, you’ll first have to understand why ISPs block images from your email messages in the first place. The top reasons Gmail, Hotmail, and others block images is privacy. Typically there is a one pixel image embedded into each email that is sent. When you open this email message, Gmail calls back to the email marketer’s server to retrieve the one pixel image. When that happens, the email marketer’s server now knows you’ve opened the email. And that verifies your email address is valid, is being used, by you, right now, at this very moment, in the privacy of your own home, and there you sit without yet having run the straightening iron through your hair. Now, that email marketer knows what you look like without makeup and hair frizzed all over the place. Well ok, so he doesn’t know that much. But it is still a validation to the sender that your address is in use. And if the sender was a spammer, you wouldn’t want him to know that.

The reason Gmail wants to block images is infrastructure

Very few words in the English language are as boring as the word “infrastructure.” You want to lose a bunch of readers of your blog articles quickly? Just pop that word into print and you’ll see what I’m talking about. Concerning Gmails desire to preserve infrastructure, Richard Evans, Director of Partner Marketing at Silverpop, says

Rendering 3k worth of HTML vs. 30k of HTML and images across millions of inboxes and dozens of emails per inbox each day is a substantial reduction in load on the (email) infrastructure.

If you are Gmail, and you have millions of inboxes, you’d be very interested in reducing the load on your infrastructure. Thus,

Gmail has a vested interest in blocking images in emails

Also, consumers are reading more and more emails on mobile devices and thus are incurring higher data usage fees. Setting a mobile device to disable images will reduce data usage and thus consumers are already demanding a lower filesize of their individual emails.

Mosaics will be blocked as well

After all, mosaics, which are meant to temporarily replace an image, are somewhat large in filesize themselves. If the ISP is blocking your 50k image because of their interest in reducing load on their infrastructure (sorry, had to use that word again), and now you’re slipping a 48k mosaic in there, Gmail will probably not like that.

Gmail will create scanning technology that determines that a mosaic is being used in an email, strip it out, and leave you with the same email-images-not-being-displayed problem that you started with. After a while of having mosaics blocked, I can foresee some not-so-intelligent email marketer who will try to game the system. They’ll try decreasing the number of rows and columns used in their mosaics to try to skirt around the Gmail filter. But once Gmail catches up on that little trick, the marketer just might find themselves blocked. Or worse, banned. Or worse still, flummoxed (whatever that means). Or worst-est still, they might get fired from their current email marketing role and have to come work here and sit next to Loraine (flying ficus trees are dangerous; just a warning.)

Getting images displayed

So what can you do to avoid this whole “images blocked”, “mosaics blocked”, “emails banned”, “ficus tree thrown at me” situation? Richard Evans continues, saying,

Get back to basics. If you follow these steps you’ll do a lot better getting your images displayed in the first place.

  • Only send to true opt-in subscribers
  • Ask recipients to add you to their safe senders list (try a set of dedicated campaigns targeted to just recipients at a single ISP asking them to add you to their safe senders list (read this article on How to double your Gmail inbox placement rates
  • Encourage recipients to click through or reply to your email directly-remove unengaged subscribers 
  • Don’t go nuts during the Christmas season by sending huge volumes of email unless you’ve properly ramped up your sending
