Keeping all the settings same, I observe that for a certain size (with simple textual content) the emails to subscribers go as intended (well, at least the test email did – didn’t try the actual subscribers yet). However, I added an image to the newsletter and then it didn’t go to the test subscriber.
Is there a size related issue which prevents emails from going out ?
An image can trigger a spam filter. The image is hosted in your website?
Most of the time the filter is on your provider. I had such problem on few installation where removing the image solved the problem… And when discovered I contacted the provider to ask it to tune the spam filter. Let me know!
Thanks Stefano – that helped. I was able to chat with the support and essentially get my SMTP configuration right. Apparently, it wasn’t – though strangely, my all-text emails/newsletters were still going out.
Now since I’ve got my SMTP correct, I experimented with sending out a newsletter containing a (600×400) image. Here’s the interesting part: _some_ of the recipients (mostly gmail accounts) did not receive it.
