I think what Brian and the testers are missing is that 15k is neither big enough to be impressive nor small enough to be inviting. It’s not a number that works effectively as social proof, and while I can’t test it out myself, I believe, based on evidence for social proof around the web, that DIYthemes would have had much better success with a combined number in the 50k+ range as mentioned above.
In 2002 the European Union (EU) introduced the Directive on Privacy and Electronic Communications. Article 13 of the Directive prohibits the use of personal email addresses for marketing purposes. The Directive establishes the opt-in regime, where unsolicited emails may be sent only with prior agreement of the recipient; this does not apply to business email addresses.

We also love how consistent the design of Uber's emails is with its brand. Like its app, website, social media photos, and other parts of the visual branding, the emails are represented by bright colors and geometric patterns. All of its communications and marketing assets tell the brand's story -- and brand consistency is one tactic Uber's nailed in order to gain brand loyalty.
The most advanced email marketing services offer custom workflows where you can specify triggers based on actions (such as opening an email or making a purchase) or on inaction (such as ignoring emails). With these services, you can also set up a series of emails (such as tutorials) to be sent to segments of users, and you can pause or stop a campaign at any time. You can also move contacts into new segments once they have completed tutorials.
So, building up lists of emails is a task you must put some effort behind in order to kick your email marketing efforts into gear. The problem is nobody really wants more email, particularly spam from unknown sources. When I talk about buying email lists, I’m am not talking about buying or renting so called opt-in lists from list brokers. I’m talking about offering something of value as a way to motivate someone to willingly exchange their email address with you in order to receive your offers and additional contact.
Video advertising - This type of advertising in terms of digital/online means are advertisements that play on online videos e.g. YouTube videos. This type of marketing has seen an increase in popularity over time.[51] Online Video Advertising usually consists of three types: Pre-Roll advertisements which play before the video is watched, Mid-Roll advertisements which play during the video, or Post-Roll advertisements which play after the video is watched.[52] Post-roll advertisements were shown to have better brand recognition in relation to the other types, where-as "ad-context congruity/incongruity plays an important role in reinforcing ad memorability".[51] Due to selective attention from viewers, there is the likelihood that the message may not be received.[53] The main advantage of video advertising is that it disrupts the viewing experience of the video and therefore there is a difficulty in attempting to avoid them. How a consumer interacts with online video advertising can come down to three stages: Pre attention, attention, and behavioural decision.[54] These online advertisements give the brand/business options and choices. These consist of length, position, adjacent video content which all directly affect the effectiveness of the produced advertisement time,[51] therefore manipulating these variables will yield different results. Length of the advertisement has shown to affect memorability where-as longer duration resulted in increased brand recognition.[51] This type of advertising, due to its nature of interruption of the viewer, it is likely that the consumer may feel as if their experience is being interrupted or invaded, creating negative perception of the brand.[51] These advertisements are also available to be shared by the viewers, adding to the attractiveness of this platform. Sharing these videos can be equated to the online version of word by mouth marketing, extending number of people reached.[55] Sharing videos creates six different outcomes: these being "pleasure, affection, inclusion, escape, relaxation, and control".[51] As well, videos that have entertainment value are more likely to be shared, yet pleasure is the strongest motivator to pass videos on. Creating a ‘viral’ trend from mass amount of a brands advertisement can maximize the outcome of an online video advert whether it be positive or a negative outcome.
CPC (Cost Per Click) or PPC (Pay per click) means advertisers pay each time a user clicks on the ad. CPC advertising works well when advertisers want visitors to their sites, but it's a less accurate measurement for advertisers looking to build brand awareness.[63] CPC's market share has grown each year since its introduction, eclipsing CPM to dominate two-thirds of all online advertising compensation methods.[24]:18[62]:1
Rob, you don’t say who ‘booted’ you from using it. A significant GDPR factor is non-profits having to consent/re-consent those on established email lists and experiencing significant proportions of lists being lost because people miss the notifications or are too busy to fill in yet more forms. However, I have found a few using a ‘one-touch’ re-subscription button that takes immediate effect, without the recipient having to do anything else. It would appear that the re-subscription rate is higher, the easier it is to activate. On enquiry, I was told that they were using mail chimp for this.
All text is boring, but too many images, in relation to the amount of text in the email, can actually increase the likelihood your email will get picked up by a spam filter (spammers use this tactic, to hide spammy words from filters). In addition, images draw attention, but you do not want them to draw too much attention, away from important text.  You’ll be in good shape if you enter your text first, then sprinkle images where it’s appropriate. 

While it’s tempting to say that we were able to create such a massive email list all by ourselves the reality is that it impossible to get that far without the help of some friends. As an entrepreneur one of our most valuable resources is our community of peers. While it may be easy to view others in your niche as your competitors, you’ll actually get a lot of more out of your entrepreneur community if you actually view them as potential partners who can help you out. http://fredericgonzalo.com/wp-content/uploads/2017/05/email_2.jpg

Most graphic designers managers have at least a bachelor’s degree—usually in art, computer science, or marketing. Classes in all of these areas will help a graphic artist gain a better perspective of what consumers (and employers) are looking for. In addition, internships and volunteering of design services for non-profit organizations are fantastic ways for artists to build a portfolio prior to entering the field.

Direct mail is a type  of direct marketing in which businesses send letters, postcards or other promotional materials to past, current or potential customers or clients. Direct mail campaigns may be targeted to either a consumer or business or both.  In many cases, the mailing is directed to a target demographic (i.e. home owners) or geographic market (i.e. a specific neighborhood). In most cases, it's mass or bulk mailing, but you can send direct mail in smaller quantities as well.
