I've just started planning a design for a promotional email. There's going to be a large image near the top of the email with the word FREE in large letters making up part of the image.
I was wondering whether this might cause some trouble with spam filters. I'd imagine if you wrote FREE in huge letters in text it might trigger some filterage but do spam filters scan images (using some kind of visual text recognition scanning technology) for text?
I have heard of some filters scanning image content, which was a while back when loads of image-based stock spam was being sent. I haven't heard much about this since, but based on experience the vast majority of filters do not looks for specific words within images.
If you want to be sure, you can always give it a run through our spam testing tool.
Yeah needs to be done. I'll let you know what I find.
