Email Marketing
Owing to its ease of use, email has become a very cost-effective marketing channel. Keeping in touch with customers has become incredibly simple; it's just a question of sending an email.
There is an important distinction between email marketing and Spam. You need to make sure that what you are sending is relevant to the recipient. A badly placed message could in some instances backfire.
Email marketing does provide great opportunities to communicate new products, new prices, discounts, special offers or any other company information you think might be of interest to the customer. It's a chance to reinforce your brand in the customer's mind too.
There are plenty of off-the-shelf packages available to help collate your marketing data and capitalise on it. Please note, the use of email marketing is governed by legislation, so make sure you are up to date on what is and isn't allowed - a fact sheet on this is available from the Red-tape team.
