The last step in completing a successful direct mail campaign is measuring success. While noticing that sales increased during the time you were running the campaign, or that many people used the coupon code that was on your postcard provides a good thumb in the air estimate, it’s important to get a better grasp on how much revenue came directly from sending direct mail.
Every ESP will give you tools to create an opt-in form for your site. Generally speaking, the less information you ask for (at this initial stage, at least), the better. The more information you ask for, the less likely your prospect is to complete the process. You’ll obviously need to ask for an email address, and I also highly recommended that you ask for a first name so you can personalize your emails. However, asking for any information beyond these two fields can decrease conversion rates significantly without adding much valuable data.
Not really. Email addresses that belong to an "opt in" list have opted to receive emails from, say, the list-purchasing company -- not your company. Even if the opt-in process includes language like, "Opt in to receive information from us, or offers from other companies we think you might enjoy," the fact is the recipient doesn't recall having a prior relationship with you, specifically. This makes it highly likely for the recipients to mark you as "spam" when you arrive in their inboxes. Hey, if they don't recognize you or remember opting in to communications from you ... can you blame them?
Just like with any other form of advertising, you will need to hit people with your message more than once in order to maximize effectiveness. Your first send might pique their interest, but people are receiving mail at the same time they are getting home, and are facing many distractions. By consistently sending marketing messages, you increase the chance that they will convert.
Ensure that your email meets spam guidelines. The CAN-SPAM Act are laws that govern how you can craft emails. To stay compliant with the act, there are several things you must include and things you must avoid doing to ensure that your emails aren't considered spam.[9] For one, there must be an unsubscribe button somewhere in the email so that people can opt out of receiving them. Another rule is that recipients must know who they are receiving the email from, so include an accurate header or reply address where they can point their concerns or comments.[10]

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.

If you are still interested in trying direct mail, I would suggest using USPS Every Door Direct Mail Service. With this service, you can target the specific area you are interested in sending a mailer to. If you have the budget, send out 1,000 direct mail pieces to start and see how many sales you get. It’s a good idea to include a promotion, like 15% off of your first purchase, to entice people to buy your product. If you use a code that is unique to your direct mail campaign, you will also be able to track how many sales came directly from your direct mail piece.
There are many vendors out there who sell lists or rent them (though renting means that the list seller maintains ownership and control of the email list). These are collections of email addresses that the vendors sell to any business or individual who can pay the fees. Your email list is considered to be a purchased or shared list if it’s provided to you by a third party, like an email list vendor or affiliate. There's a few ways that vendors build these non opt-in email lists.
