I broke this post into two sections so that I could walk you through the entire list building process. Part one will focus on the technical aspects of creating a path that helps your blog’s visitors become subscribers. And part two will focus on engaging those subscribers with effective email campaigns. All in all, by the end of this post, you’ll have everything you’ll need to build a massive email list. Let’s get started!
Established Enterprise software providers at the big end of town including IBM, Oracle, Salesforce, Adobe and Teradata started building their own platforms. But to accelerate their evolution they started acquiring technology start-ups that added features and market share.  Salesforce bought Exact Target, IBM purchased SilverPop and Oracle bought Eloqua.
Groups are specialized list fields that correspond to fields on your signup forms. They let you ask your contacts to self-categorize with preset responses that you provide. For example, a garden shop might ask their contacts what best describes them: a gardener, landscaper, or indoor plant enthusiast. After contacts self-select their interests, you can create internal tags based on group data, or send email campaigns to a segment containing one group, a few groups, or all of them.

The following table provides a list of the version and build numbers for each update to Office 365 ProPlus released in the following update channels: Monthly, Semi-Annual (Targeted), and Semi-Annual. Each entry in the table links directly to the release notes for that release. The release notes provide information about features, security updates, and non-security updates that are included in the update to Office 365 ProPlus.

The key here is to ask regularly rather than just once or twice. Most of your followers only see a fraction of your posts, and you should be getting new followers every day, so it makes sense to request subscriptions at regular intervals. If you can offer some sort of incentive or even just promise exclusive content within your emails, that helps too.
