Introduction to Email & Multichannel Marketing

Email remains one of the most effective digital marketing channels because it gives businesses direct access to their audience.

Unlike paid ads, where visibility stops when the budget stops, email allows a business to keep communicating with subscribers after they join the list. This makes email an owned channel, meaning the business has more control over the relationship with its audience.

Email is useful because it is:

• cost-effective;
• flexible;
• personalizable;
• easy to automate;
• suitable for both promotional and educational content;
• useful across the full customer journey.

Email can include banners, text, buttons, product recommendations, surveys, countdown timers, and personalized content. This makes it more flexible than channels with strict character limits or fixed formats.

Email vs. Paid Ads

Paid ads are useful for reaching new audiences, but they depend on ongoing budget. Once the business stops paying, visibility usually stops as well.

Email works differently. Once someone subscribes, the business can continue communicating with that person through campaigns and automations.

Email also benefits from trust. A subscriber has chosen to hear from the brand, while an ad is shown because of platform targeting.

In simple terms:

Paid ads help you reach people. Email helps you build and maintain the relationship.

Main Email Use Cases

Email is not only for promotions. It can support the entire customer lifecycle.

Common use cases include:

Promotions

Used for seasonal campaigns, product launches, limited-time offers, and sales announcements.

Welcome Journeys

Used to introduce the brand, set expectations, educate new subscribers, and encourage the first purchase or first action.

Reactivation

Used to reconnect with inactive subscribers who have stopped opening, clicking, purchasing, or engaging.

Loyalty

Used to reward loyal customers with exclusive access, special offers, birthday surprises, 

The Power of Multichannel Communication

If email is the foundation, multichannel marketing is the amplifier.

Customers do not interact with brands in only one place. They move between inboxes, phones, websites, apps, social media, and messaging platforms throughout the day.

Multichannel marketing means using multiple communication channels together in a coordinated way, instead of relying on only one channel.

The goal is not to repeat the same message everywhere. The goal is to use each channel for the role it performs best.

When and How to Use Each Channel

Email is best for detailed communication.

Use email for:

• storytelling;
• product education;
• newsletters;
• promotions;
• product recommendations;
• onboarding;
• lead nurturing.

Email is ideal when the message needs more context, visuals, or explanation.

SMS is best for short, urgent, time-sensitive messages.

Use SMS for:

• flash sales;
• reminders;
• last-chance offers;
• delivery updates;
• event reminders;
• cart recovery nudges.

Because SMS is direct and personal, it should be used carefully. Too many SMS messages can feel intrusive.

Push notifications are useful for quick, actionable reminders.

Use push notifications for:

• bringing users back to the website or app;
• limited-time reminders;
• product alerts;
• re-engagement messages;
• app activity prompts.

They work well when the user is recently active or already engaged with the brand.

Other channels, such as WhatsApp, Messenger, or social DMs, can be useful for conversational engagement and customer support.

Use them for:

• answering questions;
• sending order updates;
• confirming appointments;
• sharing personalized offers;
• helping customers make decisions.

How Multichannel Marketing Works

A good multichannel strategy creates a connected journey.

For example, a customer may first discover a brand through an ad, then subscribe through a pop-up, receive an email, abandon a cart, get a reminder, and finally convert after a more urgent message.

The key is that each channel should add something useful.

A bad multichannel strategy repeats the same message everywhere.

A good multichannel strategy uses:

• email to explain;
• SMS to create urgency;
• push notifications to remind;
• ads to attract;
• messaging channels to support conversation.

Why Timing, Context, and Personalization Matter

The difference between effective and ineffective multichannel marketing is execution.

Timing

Messages should arrive when they are useful.

Automation helps with this because every customer behaves differently. One person may browse at night, another during lunch, and another during the weekend.

Automations can trigger messages at the right moment, such as:

• welcome emails after signup;
• cart abandonment reminders;
• replenishment reminders;
• birthday offers;
• back-in-stock alerts;
• webinar reminders.

Context

Each message should match the customer’s situation.

If someone already purchased, they should not keep receiving abandoned cart reminders. If someone downloaded a beginner guide, they should not immediately receive an advanced sales pitch.

Context makes communication feel relevant instead of random.

Personalization

Personalization goes beyond using the subscriber’s first name.

Strong personalization uses behavior and preferences, such as:

• products viewed;
• items added to cart;
• categories browsed;
• purchase history;
• frequently repurchased items;
• downloaded resources;
• event registrations.

Instead of saying:

“Sale on all products”

A personalized message could say:

“The serum you viewed is now 15% off.”

Or:

“Your email marketing checklist is ready. Here’s the next step.”

Example 1: LumiSkin

LumiSkin launches a campaign for a new hydrating serum.

The customer journey could look like this:

1. A visitor sees an Instagram ad for the new serum.
2. They visit the website and browse hydrating skincare products.
3. A pop-up offers 10% off in exchange for subscribing.
4. They receive an email explaining how the serum works and who it is best for.
5. They add the serum to cart but do not complete the order.
6. The next day, they receive a cart abandonment email with the product they left behind.
7. If they still do not purchase, they receive an SMS reminder with a short deadline.

In this case, each channel has a different role:

• the ad attracts attention;
• the pop-up collects the contact;
• the email educates;
• the cart email reminds;
• the SMS creates urgency.

Example 2: GrowthLab Academy

GrowthLab Academy promotes a free webinar about email marketing.

The customer journey could look like this:

1. A visitor reads a blog article about email marketing.
2. An embedded form invites them to register for the webinar.
3. They receive a confirmation email with webinar details.
4. A reminder email is sent one day before the event.
5. An SMS reminder is sent one hour before the webinar starts.
6. After the webinar, they receive a follow-up email with the replay and a course invitation.

In this case:

• the blog article builds interest;
• the embedded form captures the lead;
• email provides details and education;
• SMS reminds at the right moment;
• the follow-up email continues the relationship.
