Buying email lists doesn't just damage your deliverability and brand reputation -- it can also put your email account at risk. Email clients like Gmail, Yahoo!, and Outlook don't want to be associated with accounts that recipients repeatedly flag as spam. Email service providers like AWeber go as far as immediately closing your account if it suspects you're sending unwanted content.
Not only was this initial email great, but his response to my answers was even better: Within a few days of responding to the questionnaire, I received a long and detailed personal email from Matt thanking me for filling out the questionnaire and offering a ton of helpful advice and links to resources specifically catered to my answers. I was very impressed by his business acumen, communication skills, and obvious dedication to his readers.
A web-based interface is often available to allow people to subscribe, unsubscribe, and change their preferences. However, mailing list servers existed long before the World Wide Web, so most also accept commands over email to a special email address. This allows subscribers (or those who want to be subscribers) to perform such tasks as subscribing and unsubscribing, temporarily halting the sending of messages to them, or changing available preferences - all via email. The common format for sending these commands is to send an email that contains simply the command followed by the name of the electronic mailing list the command pertains to. Examples: subscribe anylist or subscribe anylist John Doe.
Are you willing to alienate people who disagree with your opinion? Sure, not everyone who disagrees with you will unsubscribe. But if you can’t take the risk of alienating a large portion of them, it’s better to avoid the topic. The only exception are friendly disagreements. For example, it can be a good idea to show your support for a specific sport team, even if you know many in your audience like another team. As long as they don’t take the sport very seriously, it can be just a fun thing to talk about. I could, for example, tell that I’m more of a dog person (we have two dogs) than a cat person. I have nothing against cats, but I like walking with dogs. I doubt almost any cat person will hold that against me.
Then, let's say you write 30 blog posts a month. That means you'd get 60 leads in a month -- 2 from each blog post. Now keep doing that for a year. The work you did to blog that first month will continue to drive leads throughout the year. That means you're actually getting 4,680 opt-in contacts a month by the end of a 12-month period because of the compounding effects of blogging -- not just 720 opt-in contacts (60 leads*12 months).
