The 11 best Email Marketing platforms in 2025

Email marketing continues to be an essential tool for any business thanks to its ability to deliver measurable results and its high return on investment. For every euro invested in email marketing, businesses can generate up to 36 euros in revenue.

Not only is it a direct way to communicate with your customers, but it also allows you to personalize messages and automate campaigns tailored to your audience’s needs. This makes it a must-have strategy for boosting sales, building customer loyalty, and fostering lasting relationships.

How to collect email adresses for Email Marketing

Collecting email addresses for email marketing must be done ethically and in compliance with legal regulations, such as the General Data Protection Regulation (GDPR) in Europe. Here are some legal and effective strategies:

1. Create forms on your website or landing pages

• Add an eye-catching form to your website where visitors can sign up to receive valuable content, such as guides, ebooks, discounts, or newsletters.
• Use clear calls-to-action: “Subscribe to receive exclusive tips” or “Download our free ebook on X.”

2. Host events or webinars

• Organize online or in-person events on topics relevant to your target audience. Request email addresses as part of the registration process.
• Include consent checkboxes for future communications.

3. Use lead magnets

• Offer exclusive content like:
  • Free ebooks.
  • Useful templates.
  • Tools or resources.
  • Access to courses or webinars.
• The key is to provide valuable content for your audience.

4. Implement loyalty programs

• If you run a repeat business (e.g., e-commerce), offer benefits like discounts or points in exchange for signing up.

5. Social Media campaigns

• Use Facebook, Instagram, or LinkedIn Ads to drive traffic to email capture pages.
• Offer incentives: “Get an exclusive 10% discount by signing up here.”

6. Collaborate with other businesses

• Partner with non-competitive businesses to share audiences and promote joint events or campaigns.

7. Collect emails at physical events

• If you attend trade shows or conferences, gather emails through surveys, giveaways, or discount codes.

8. Retarget current customers

• If you have a database of customers from previous purchases, request their consent to add them to your email list.

9. Run contests

• Launch online contests or giveaways, asking participants to provide their email addresses to enter.

Effective Email Marketing: Practical tips to connect with your audience

Speak directly to your subscribers

When writing emails, use a friendly and approachable tone. Address readers in the second person, using words like “you,” to make them feel personally spoken to.

For example: ✅ “Discover how your business can stand out and gain more visibility.”
❌ “We offer tools to improve businesses.”

Focus on benefits, not features

Rather than describing what you do, highlight how your products or services improve your customers’ lives. Answer the question: What’s in it for me?

Instead of saying: “We design websites with advanced SEO.”
Say: “Attract more visitors to your website and turn them into clients with optimized design that ranks on Google.”

Be human and authentic

Forget the cold, corporate tone. Write as if you’re emailing a friend. People appreciate sincerity and avoid emails that sound generic or overly technical.

For example: ✅ “We understand managing an online business can be challenging. That’s why we’re here to help.”
❌ “Our mission is to optimize integral business solutions.”

Have a clear goal for each email

Every email you send should have a single purpose. Whether it’s downloading something, scheduling a call, or visiting your website, define the goal and ensure the content clearly leads to that action.

Make it easy to read

No one wants to read long, dense paragraphs. Structure your content to make it visually appealing:

• Use headings and subheadings.
• Include lists or bullet points.
• Leave space between text blocks.
• Add images or GIFs to reinforce your message.
