What is email marketing

Email marketing is one of the most powerful tools in digital advertising. It's fast, cost-effective, and highly customizable. Emailing refers to the process of sending bulk emails — usually commercial — to a list of contacts. These emails promote products or services, or they may serve to inform subscribers, which is commonly referred to as a newsletter.

Email Deliverability

Deliverability refers to whether your emails reach your recipients’ inboxes — not their spam folders. Internet Service Providers (ISPs) are now stricter with filtering rules. Poor list quality, bad reputation, or low engagement can get you flagged.

How an Email Campaign Works

To be effective, a campaign must follow five strategic steps:

1. Target

Start with market research and an opt-in database. Know your audience before sending. Never buy low-quality lists — see our warning in Buy or rent email lists: risks and rules.

2. Create

Design your email with a clear layout, attractive visuals, and compelling CTAs. Read more about email graphic and technical design.

3. Test

Before launching, test different versions (A/B testing) to see which one performs better.

4. Send

Use reliable tools to manage timing, frequency, and automation. Proper configuration can make or break a campaign.

5. Analyze

Review open rates, click rates, and bounce rates to improve future campaigns. Don't forget to clean your list — explore our page on how to verify and maintain your mailing list.

Strategy: Prospecting vs Loyalty

Prospecting Emails

These are cold emails aiming to attract new customers. They need to be short, direct, and engaging. Include clear links and calls to action. To optimize performance, check our pre-campaign checklist.

Customer Loyalty Emails

These include newsletters and post-purchase emails. Their goal is to build trust and maintain engagement. Informative content, exclusive offers, or loyalty programs can turn a one-time buyer into a loyal customer.
