Ad blocking, or ad filtering, means the ads do not appear to the user because the user uses technology to screen out ads. Many browsers block unsolicited pop-up ads by default. Other software programs or browser add-ons may also block the loading of ads, or block elements on a page with behaviors characteristic of ads (e.g. HTML autoplay of both audio and video). Approximately 9% of all online page views come from browsers with ad-blocking software installed, and some publishers have 40%+ of their visitors using ad-blockers.
Have a few different buttons on your email template: separate social media buttons that produce pre-written social posts linking to a webpage version of your email, and an "Email to a Friend" button that transfers the email into a compose window so your contacts can instantly forward the message. Just make sure your email has an opt-in button so each new viewer can subscribe to more emails from you if they like what they see.
Next up is building an email newsletter. The best services offer several ways to do this; you can import your own HTML, start from scratch, or use a pre-designed template. Most of these services have drag-and-drop UIs that let you choose exactly the elements you want to include, as well as image libraries in which you can store assets such as your logo or company photos. Tools that let you test your emails for spam are also essential since there are some seemingly innocuous terms that may send up red flags and drop all of your hard work into your subscribers' junk folders or, worse, get your emails banned before they ever reach their recipients.
