If digital marketing were the Olympic games, SEO, PPC and Social Media Marketing would be your sprints, swimming and gymnastic events. Everyone tunes in to these and loves the spectacle. In contrast, E-mail marketing is fencing; many people don’t give it enough love, but those who do find great joy and success.

For those of you sitting on the fence (😏See what we did there?😁), this article might help clarify a few things about this once-heralded form of marketing.

Before we get into the technicals, let’s take it back to basics.

What is E-mail Marketing?

One of the oldest forms of digital marketing/communication, e-mail marketing, is a digital marketing strategy that involves sending e-mails to a group of recipients to build and maintain relationships, increase brand awareness, and drive sales or conversions. It’s highly effective and direct communication with your audience, allowing you to reach them in their inboxes.

In today’s digital age, e-mail marketing remains a powerful tool for businesses looking to connect with their audience, promote their products or services, and drive revenue. It’s a cost-effective, targeted, and versatile way to communicate with potential and existing customers. In this comprehensive guide, we will delve into the world of e-mail marketing, covering everything from its fundamentals to advanced strategies to help you harness its potential and achieve your marketing goals.

Fun Fact: In 1978, the first marketing e-mail was sent to an e-mail list of 400 addresses, resulting in approximately $13 million in sales.

Building E-mail Lists

Building a high-quality e-mail list is the foundation of successful e-mail marketing. Your e-mail list is a collection of individuals who have opted to receive your e-mails. 

Here’s how to build and maintain a robust e-mail list:

Opt-in Forms: Place opt-in forms on your website, landing pages, and social media profiles to capture e-mail addresses from interested visitors.

Lead Magnets: Offer valuable incentives like eBooks, discounts, or webinars in exchange for e-mail sign-ups.

Segmentation: Segment your e-mail list based on demographics, behaviour, and preferences to send targeted and relevant content.

Cleanse Your List: Regularly remove inactive or bounced e-mail addresses to maintain list quality and deliverability.

The POPI Act 

The Protection of Personal Information Act (POPI) is a law that regulates the collection, processing, and storage of personal information by organisations. The act aims to balance the rights of individuals to protect their personal information with the needs of businesses to collect, use, and store such information for legitimate business purposes.

POPI caused quite a shake-up in the marketing world as it forced many businesses to change their way of marketing to people and how they came into possession of the information of people to market to.

If you need a quick brush-up on the key provisions of the act, here you go:

Consent: Organisations must obtain the informed consent of individuals before collecting, processing, or storing their personal information. You must make it blatantly obvious to the user that they are signing up to a mailing list.

Purpose Limitation: Enterprises must only collect, process, and store personal information for specific, explicitly defined, and lawful purposes.

Data Quality: Companies must take reasonable steps to ensure that the personal information they collect, process, and store is accurate, complete, and up-to-date.

Data Security: Businesses must take reasonable steps to protect the security of personal information, including protection against unauthorised access, damage, loss, or theft. Storing information on Excel spreadsheets and sharing them simply won’t cut it anymore.

Data Retention: Organisations must only retain personal information for as long as necessary to fulfil the specific purpose for which it was collected.

Data Access and Correction: Individuals have the right to access their personal information held by organisations and to request the correction of any inaccurate information.

Data Transfer: Organisations must obtain the consent of individuals before transferring their personal information to third parties and ensure that such third parties are subject to equivalent protection.
