Explain clearly what people will receive in return for their emails: tips, tricks, news, case studies, special offers, promotions, or whatever you will send them. I.e. give a solid reason to subscribe to your mailing list.
Social psychologist Howard Leventhal conducted a study on urgency by testing how people responded to packets of information about tetanus. His goal was to see how he could convince more people to get vaccinated.
Effective direct marketing begins with data. Marketers examine categories of customers or prospects they think will be interested in their product or service, and develop or procure lists for making contacts.
When you have a list of subscribers who have specifically agreed to receive emails from you, you have an asset that can be leveraged over and over again. You can use that email list to drive traffic to different websites and sales pages again and again, and this is why you must cherish your list like an apple of your eye. The better you treat your list; the better the return will be when you want it.

2) Free tools. Create templates, rank checkers, calculators and widgets and let people use them to their heart’s content and even enable them to pass them around. Aaron Wall of SEO Book is a master of this one.
Is bounce rate an accurate metric to look at when valuing your email marketing campaigns and the quality of your marketing list? I don’t think so. Most of email blasts have an average bounce rate of 20%. It’s just the reality of it. Instead, I would use ROI as a standard metric for any type of marketing efforts.
Start by creating a sign up form and adding the form to your website. Try offering an incentive in exchange for an email address, like a free course, ebook or discount.  Then, write engaging content that readers will find valuable.

Throughout the day, you and your employees probably interact with many customers and prospects on the phone. Before you hang up, always ask if they would like to join your email list. Give them a brief statement of the benefits of enrolling — for example, exclusive offers and discounts only available to email subscribers.
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.
Select your target market – Who are you going to be marketing to? Try to get as specific and relevant as possible, only broadening your reach when you feel you need more people to reach out to. The more targeted your audience, the more targeted you can make your approach. Remember, however, that while adding data to flush out your target market is good, you need a way to actually collect this data and your audience.
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.
If you don’t currently have any downloadable guides to offer (more on that later), it’s best to stick with a traditional newsletter page like this one. A page like this offers an opportunity to outline the benefits of joining your newsletter, letting you reach current blog readers who need that little extra nudge to sign up.
According to recent research examining brain activation, few things light us up quite like seeing our names in print or on the screen. Our names are intrinsically tied to our self-perception and make up a massive part of our identity.
And sure, when you compare a nickel for a thousand emails to, say, a hundred bucks  for a thousand emails (which is TWO THOUSAND TIMES the cost), it’s easy to further calculate that even if the response rate is only 1/2000th as good, you’re still coming out ahead.
You’ll still run into the same problems as buying a list. The people you’re emailing did not request information from you directly, and will likely view your messages as spam. The more complaints you get, the worse your delivery rate will be.
People like more choices, so consider creating subscription levels that let people sign up to receive content that’s relevant to them. For example, if you sell widgets and tax advice, provide three options on your opt-in form that allow users to sign up to receive info about widgets, info about tax advice or both. Further customize by allowing them to designate how frequently they’d like to hear from you — weekly, monthly or only when something really special is going on. People may be more likely to sign up for your email list if they have some control over the content they’ll receive.
Hyperlinked email signatures can lead people to a landing page where they can sign up for your mailing list. Plus, if you’re already in a natural email conversation with them, subscribing to more emails can be a natural next step.
Design The single column vs. dual column debate will arise here, but there are also a ton of other design elements that can be tested in an email, such as the images included (if there are any), the color scheme, the styling of the text, etc.
The identity of the marketer and/or operator and details of where and how they may be contacted should be given in the offer, so as to enable the consumer to communicate directly and effectively with them. This information should be available as a permanent reference which the consumer can keep, i.e. via a separate document offline, an online document, email or SMS; it should not, for example, appear only on an order form which the consumer is required to return. At the time of delivery of the product, the marketer’s full name, address and telephone number should be supplied to the consumer.
All direct marketing communications must include some method with which to track responses. A call to action might direct customers to call a specific number exclusive to that campaign, or to click on a link to a website with a landing page that exclusively handles responses from a given campaign (See also Post-Click Marketing). Direct marketers use the response-rate data to gauge how effective their communication is, and whether or not it needs to be changed for the next release. Such data is not only used to adjust the immediate campaign, but is also coordinated with data from other campaigns in order to present the direct marketing team with a better overall picture of their target markets. The data can then be used to more effectively optimize communication for specific market segments.
If the desired outcome of any webpage is an email signup, the structure of the content should be styled as a landing page; in other words, no sidebars, no footer, a subdued header, and plenty of single-column copy that dives right in to what the page is about.
All of the things I have gone through in this post are great ideas and experiences I have made, and I know for sure that they will help you to effectively grow your email list and keep your email marketing budget intact.
