Email newsletters are still one of the best ways to keep in constant contact with your customers. The fact is some of them might not have embraced social media just yet and email newsletters serve as a great personal way of communication.

Some of you will have already got yourself setup and maybe wondering how to grow your list. So direct from the people that should know (MailChimp the email newsletter service we use a recommend) here are some of their tips.

• Place your email newsletter signup form on your home page (MailChimp gives you free signup boxes that you can customize and copy-paste to your website).
• Link to your signup form from every page of your website (you might add a link to your footer, or side navigation).
• Place a link to your email signup form in your email signature (ask everyone in your company to do it too)
• Add the link to your signup form in all the invoices your company sends
• Offer free giveaways to one lucky subscriber (it can be a company t-shirt, or something kooky, like a 20 pound box of banana candy).
• Post free whitepapers or helpful articles on your site. They'll get downloaded like crazy, if you just offer them for free, and with no registration. Inside your whitepaper, place your own "full page ad" to your newsletter.
• Send out personal, one-to-one emails to all your clients, and ask them to please signup to your newsletter.
• In your "Contact Us" form on your website, add a checkbox to "signup for our newsletter"
• Add an "opt-in for our newsletter" checkbox in your e-commerce checkout page.

So there are just some quick tips for growing your opt-in email newsletter list.
