No one-click unsubscribe? It's spam.

Your marking emails might not have a one-click unsubscribe link but Gmail certainly has a one click spam button.

Two ways you can keep me as a subscriber:

1. Remind me what the hell it is your company does/sells in the first sentence. Between my signup and now, chances are about 95% that I forgot what I even signed up for.

2. Make it easy to unsubscribe. That means a very visible one-click link. Unsubscribing doesn't mean I'm no longer interested in your product. But making it difficult to unsubscribe says a lot about how I will be treated as your customer.

Go easy on the HTML / CSS / Images.

If I click an unsubscribe link and the company wants me to sign in, I mark it as spam in gmail.

Linked-In has the spammiest email protocol out of any service I have ever used. Even after signing-in there is no one-click-to-unsubscribe button (they split it into about 12 scattered categories), and they create new categories periodically and opt you in to them. This is downright deceitful. Pro tip: change your email to one that you never use. It literally came down to doing this or deleting my Linked-in account--unfathomable to me. Also: no more f@#$!ng emails at 4 in the morning. This seems like a jackpot CAN-SPAM class action suit.

@easternmonk: That's the thing -- I did mark them as spam in GMail. I assumed it would block future emails from Linked-in but not the case. ... Somehow they continued to come in.

@sehugg: That too! I complained about their this on Facebook and I had friends (yes, plural) who had deleted their account because of the spam and yet were still receiving it. Unbelievable

It's in violation of the CAN-SPAM Act

    You can’t charge a fee, require the recipient to give you any personally identifying information beyond an email address, or make the recipient take any step other than sending a reply email or visiting a single page on an Internet website as a condition for honoring an opt-out request.

Also a good reason to test your emails in different systems - Gmail often snips emails I receive, meaning the Unsubscribe link at the bottom is cut off. I'll bet that leads to increased spam reports.

Aweber had an article last week suggesting you put an Unsub link at the top of your emails as well. I haven't had the guts to do that for my template (EveryDayDreamHoliday) but as a consumer I like the idea.
