There are many, many tools that can aid you in your direct marketing campaigns, such as lead generation tools to help you generate your list of prospects to outreach tools, which will help you actually launch the campaign.
Other media, such as magazines, newspapers, radio, social media, search engine marketing and e-mail can be used to elicit the response. A survey of large corporations found e-mail to be one of the most effective forms of direct response.[22]
Resending the email can yield big gains, since you can potentially reach subscribers who might have missed your first email. You could try a different subject line or slightly different content in the body. You’ll also want to segment out the responders—that could be just people who ordered, or everyone who opened or clicked.
Below, you’ll get a step-by-step look at what segmentation is (and why it works), as well as some simple, yet powerful pieces of advice on segmenting subscribers to maximize the impact of your email list.
People enjoy offering feedback on information that pertains to them. On certain pages of your website, include a form that asks visitors what questions they might have about your business. You might also create a live chat tool that invites questions and email addresses from people who have stayed on your website for a certain amount of time.
I am a scientist. My e-mail has been drawn from publicly-available sites related to science. My name and e-mail is being sold as part of a 7 Million+ e-mail list to biomedical companies and anyone who wants to buy targeted lists. I NEVER gave permission to use my name and e-mail and in fact requested that my name be removed. The company continues to make profits by selling my name + 6.999 million others. I don’t care what country you are from, this is UNETHICAL and ILLEGAL (in my eyes). Of course, who as the money to try and persecute such crooks? Worse yet, if I live in South Africa and the company is selling from India, how can US laws affect or cover me? These guys work across transnational borders because they know that they can operate across international borders online, without any regulation (unless they operate from the US, perhaps). So no fear, no penalties, no recrimination, no fines, just sickening profits from unjust and unfair and illegal marketing methods. Because frauds all abuse innocents.

One service that has been really liked by the crowd is that of a company called Database of Decision Makers. It offers you a never before heard offer of replacing the bad contacts with good ones, in case you come across any. They have established a good network of lead grabbers and can offer you a healthy database of the most recent contacts, new and freshly updated.
Platforms like BuddyPress for WordPress make it easy to set up a community and foster interaction between your brand and your customers. Include a sign-up form for your newsletter on every page of the community.
Further, a consumer who does not wish to receive further prerecorded telemarketing calls can “opt out” of receiving such calls by dialing a telephone number (required to be provided in the prerecorded message) to register his or her do-not-call request. The provisions do not cover calls from political organizations or charities.[16]
OptinMonster* is a powerful option here. I’ve mentioned it in the WordPress plugins above and that’s how OptinMonster started out. It’s now a fully fledged cloud app that supports both HTML and WordPress. It provides a great overview for all of your list building efforts and makes it easy to deploy split tests with a few clicks. Pricing starts at $19/month (or $9/month when paid annually).
Thrive Architect* – This is a WordPress plugin that allows you to create custom page/post layouts. It comes with plenty of landing pages templates and integrates with most popular email providers. Price starts at $67 for lifetime updates and 12 months support.
When the presentation of an offer also features products not included in the offer, or where additional products need to be purchased to enable the consumer to use the product on offer, this should be made clear in the original offer.
Use a recognizable sender name – If your subscribers don’t recognize who is sending the email, they might not open it. Use something that is easy to recognize, this may be your name or your brand name – whatever people are more likely to recognize.
If someone actually had a good email list, they’d keep it to themselves because they don’t want to see the value of those email addresses diminished by letting other people get their hands on it. Think about it — would you sell or share the email addresses of those who have voluntarily opted in to receive email from you? I didn’t think so.
I’ve found this as possibly the most effective way to gather a lot of email subscribers in a very short period of time. Giveaways are a great tactic that leverage network effects to increase the reach of your message. 
– Provide webinars. People love free educational seminars, that’s why webinars are considered the best performing lead magnet. However they have one downside: they take more time and effort to prepare and implement. Anyway, keep webinars in your mind as they can transform your business.
We provide marketing lists to many well known global companies. I’m sure they wouldn’t have came back to extend their license with us again and again over the years if their marketing campaigns results are so poor as you said.
Not only do you make the most of a sticky situation, the emails you’ll collect by doing this are incredibly valuable as the visitor has already decided to purchase something from you. That means they are highly interested in your brand and what you have to offer.
2. The information contained is captured in a consistent form which you have control over – easier to integrate back into your customer database or tie to existing customers leveraging social channels (did you know that before? doubtful)
This is also common. Remember, if you want people to join your email list, you need to give them a reason to join. And if you’re not giving away a discount, the next best thing is this: give away content.
Selling your Email List can put you in a state of trouble. Its better if you connect with professionals on Professional Employment & Business Networking Site | Opportunity to grow your business. Here, people who may need Email list can contact you.
– Product/service registration. When people subscribe for your service or product trial, you can add an option to join your list and receive useful tips, updates, best practices, tutorials, guides, etc. etc.
If you have a brick-and-mortar presence where you interact with customers face-to-face, create an email campaign just for those walk-ins. Launch a store membership they can sign up for via email at the register. This is a smart way to keep in touch with repeat customers and reward their loyalty to your product.
While content marketing has proven itself to be the best strategy for bootstrapped startups, the problem is that most company blogs are poorly designed for conversions, focusing on featuring useless items like social media banners and category links.
