Hello Anthony,
First, I want to thank you for sharing your feedback on this. As you know, our client's satisfaction is mutual and is key to our success. I also want to let you know that we post any upcoming changes/announcements in our Bulletins section -- of which we posted details on the
6/17 update (effective, today) such as the changes made on the Opt-Out page.
That said, I understand your concern regarding the changes made to the Opt-Out page. I'll share my perspective on the matter below.
I agree that the font size and positioning acknowledging removal from a mailing list is quite large (it could probably use some better alignment and styling), but the benefit is that customers who opt-out see it very visibly that they have been successfully opted out. This will
hopefully provide enough gratification to them, so they don't report your message as spam and simply delete it. As you may already be aware, this can effectively increase overall deliverability to various ISPs.
As far as the line that reads, "Was the e-mail SPAM?" is concerned, this allows our Mail Operations team to minimize the barriers between e-mail recipients and them to report unsolicited e-mail. (That is, less hoops for a recipient to jump through to inform the team of a client who isn't exhibiting proper e-mail practices.) The following result of that question, assuming they click Yes, is our Mail Ops team will actively investigate the complaint and determine if a client is failing to send mail within our guidelines.
The best way to look at it, is this: It's much better for us to detect less than desirable email activity, than say, AOL or MSN. We can help proactively inform clients that their activity falls outside the guidelines and give them the tools and
best practices for properly sending e-mail. If an e-mail recipient has any doubt that an Opt-Out will work, they are very likely to utilize their provider's Report Spam button which, even individually, can have a drastic impact to your (and our) deliverability rating.
From my brief conversation with the Mail Ops team on this, they have received qualitative and useful feedback from recipients which aid them in their plight to provide industry-leading e-mail deliverability for all our clients.
I've let our Mail Ops team know about your feedback and they probably have a few pointers or interesting positions on the topic.
I have a question, what would you like our Opt-Out form to appear like? We're open to all of our client suggestions.
Thanks again for your feedback, we strive to provide the best experience for clients like yourself as well as your recipients. It's a win-win situation.
