"While mailing subscribers is indisputably important, there are several reasons why the importance of capturing email addresses has nothing to do with sending your new subscribers another email. And how you obtain those addresses has become critical."

If you take them aside in confidence and buy them a drink or two, most people working in email marketing will eventually admit there’s a hungry beast they have to deal with that is never full and always has an appetite for more. No matter how much or how often they feed it, it’s a bottomless pit.

"Every marketer knows that one of your greatest assets is your email list. In the '90s and early '00s, relatively little attention was paid to how you actually built that mailing list; the focus was on building the biggest mailing list possible, and mailing lists were often bought, sold, or shared. Nobody really thought about the concept of "permission", after all email was the closest thing to free advertising and marketing you could get, and if somebody had an email address, it was considered fair game."

"As email marketers we often get ‘in the weeds’ – focused on whether or not the opt-in box is checked (if you’re collecting email addresses from Canadians, CASL says it matters), agonizing over where the email sign-up call-to-action appears on your Website and trying to figure out if someone who offers to send your ‘sign up today’ message to 70 million qualified (according to them) prospects around the world is worth the $1,500 they’re going to charge you (hint: it’s likely not)."

"At FierceMarkets, a digital B2B publishing company, anywhere from 30%-80% of our email newsletter list growth comes from converting web visitors into subscribers. In this article, I’ll share what’s working for us, and hopefully you’ll be able to apply it to your organization."

"Getting end customers to go paperless is a focus for many companies and one of the easiest ways to do this is ask them to switch off paper for their bills and receive an electronic version instead."

"MarketingProfs started in 2001 and built up entirely organically a list of mailable email addresses that stands at over 300,000 today. In 2013, we deployed over 10 million such acquisition emails. So, having seen literally hundreds of advertisers trying thousands of offers has given us a great portal into what works in B2B email marketing."

"the single most important piece of data for a successful email program is the email address. You may think, "Hey Bob, thanks for that blinding glimpse into the obvious." The truth is, this is a piece of data that if often beyond the control of the email team to actually gather, as this is usually a function of the web team. "

"With leading marketing technologies already established and new technologies emerging on a seemingly daily basis, marketers are faced with making decisions about how to optimize and deliver results with their technologies of choice."

"Drip marketing describes a series of predesigned emails sent on a predetermined schedule geared toward education, branding, positioning, or selling of your product. Drip marketing emails are distributed to a broad audience; lead-nurturing emails are distributed to a specific segment."

"Triggered messaging is a rapidly growing part of marketing with extremely good ROI. It's about delivering business messages that are personalized and near-real time: often sent by email but increasingly by other channels such as within web pages. "

I got some great insights on responsive design and coding for non-techies from my colleague Luca Bellavita, a design and HTML manager for Alchemy Worx, which I shared in a recent ClickZ column. But one thing that’s been taking a lot of my head space lately is how and when to leverage responsive design and coding in unconventional ways.

"It’s a near certain fact that much of a marketer’s time is spent on analysing specific campaign ROI, or put another way, how much marketing spend was needed to generate a particular sale. It does seem to make sense that if a brand is employing a vast number of channels to reach a customer – PPC, social, email, display – it will want to know how to spend its limited resources, in order to optimise future campaigns. However, I am not convinced that campaign level ROI is the best metric for measuring campaign effectiveness."

"As email marketers, it's our job to get a slice of that Mother's Day pie. Let's take a look at how online retailers are promoting the holiday."

"Each of these titans has been aggressively building and buying their way to deliver on the promise of a CMO-focused, cloud-based, integrated cross-channel platform that places the digital marketing controls squarely in the court of the marketing organization and relieving long-standing resource dependencies on other internal and external organizations. It is a vision that, in most of these and many other competing organizations, has been branded the “Marketing Cloud,” and it is set to be the key driver in marketing technology evolution and decision-making for the coming five years."

"I call bullshit. Because - in email- relevance is irrelevant, once the consumer chooses you. (Cue the wailing and gnashing of teeth music.) Why do I know this? Statistics."

"Conversion rate optimization (CRO) is the technical term for strategically planning your tests. It’s the active process of defining the metric you’re trying to optimize, creating several hypotheses about what tweaks in your campaigns may increase your conversion rate, and measuring the effect of each hypothesis. It applies equally to email and landing pages, but I’ll limit the discussion here to email as much as possible."
