Let’s look into the 5 best email copywriting tools that can boost your email marketing efforts in 2025.

What is Email Copywriting?

Email copywriting is the process of writing an email for a customer or potential customer that will get them to buy something.

But in this case, conversion doesn’t just mean making a sale.

It could be about getting a reply to your email, someone signing up for your newsletter, or maybe a download for your ebook — really, it’s any goal you want to hit with that email.

Before we jump into knowing the different types of email copywriting tools, let’s take a moment to explore the key components of an email copy.

Key Components of an Effective Email Copy

All effective email copy contains three crucial components:

• Subject line: it’s the first thing the recipient sees and really impacts whether they’ll open your email. According to research, 47% of recipients open emails solely based on their subject lines. 

• Email body: The email body is where you’ll find the main part of your message. It can share a story, give details about what you offer, highlight social proof, or offer useful information.
• Call to action: Call to action is basically letting your reader know what to do next after they finish reading your email — like signing up for your webinar or downloading a report, for example. A study reveals that a single, clear call to action (CTA) in a sales email can boost sales by 1617%.
