They say that spam filtering is becoming a growing problem for them as the seek to deliver opt-in newsletters.
Several note that unsubscribe messages get particularly hard. Is anyone else having a problem and how are you trying to get around it?
Perhaps for HTML the best solution would be to do the unsubscribe as an image; however, most of the web-based providers force you to use their "unsubscribe" message. And even if you used an image on the HTML, there is still a problem for text-based versions - it would take some creative and convoluted writing.
I've been using Vertical Response, but increasingly I think their servers are being blacklisted. One of my clients couldn't receive his last marketing mail because his ISP had banned Vertical Response. Vertical Response customer support was a great help, and the ISP eventually lifted the ban, but how many other ISPs use the same aggressive blacklist? How many of the big providers - Lyris, E-Mail Labs, and others - are now on blacklists?
You mentioned running the mail through SpamAssassin. I think Lyris offers a similar capability on their web site. I haven't tried either yet, but I will.
I think its a great topic, Cyril. I'd like to hear how others are designing, writing, and delivering with spam filters - and blacklists - in mind.
Or are we? I have taken the word "unsubcribe" out of my newsletters and replaced it with other language that seems to less attractive to filters - saved half a point on the Lyris scale, but I am sure some people filter much harder on that word than Lyris does.
Just thought I would bounce this back up and see if anyone else had any thoughts...
