Email Marketing Terms You Need to Know (Without the Jargon)
Starting with email marketing can feel a little like learning a new language. CTR, segmentation, A/B testing — what does it all mean, and why should you care?
Don’t worry — you’re not alone. The good news is, you don’t need a marketing degree to understand these terms. Once you learn the basics, it’s much easier to plan smarter campaigns, track your success, and feel more confident hitting “send.”
Let’s break down the essential email marketing terms without the techy talk.
1. Subscriber
This is anyone who has signed up to receive your emails. They’re on your email list — which means they’ve said “yes” to hearing from you.
2. Open Rate
This tells you how many people opened your email. It’s usually shown as a percentage.
Example: Email Marketing Terms
If you send an email to 100 people and 40 open it, your open rate is 40%.
Why it matters: High open rates mean your subject line is working, and people want to hear from you.
3. Click-through rate (CTR)
This shows how many people clicked a link inside your email.
Example: Email Marketing Terms
You send a newsletter with a link to your blog. If 10 out of 100 people click it, your CTR is 10%.
Why it matters: A good CTR means your content is engaging and your call-to-action (CTA) is clear.
4. Unsubscribe Rate
This is the number of people who opt out of your list after receiving your email.
Why it matters: A few unsubscribes are normal. But if you see a spike, it might mean your content isn’t resonating — or you’re emailing too often.
5. Deliverability
This refers to whether your emails reach the inbox (instead of ending up in spam or bouncing).
Why it matters: If people never see your email, they can’t engage with it. Using clean lists and avoiding spammy language helps improve deliverability.
6. A/B Testing
Also called “split testing,” this means sending two versions of your email (A and B) to a small portion of your list to see which performs better — then sending the winner to the rest.
You can test things like:
-
Subject lines
-
Button text
-
Images or layout
-
Send time
Why it matters: It’s one of the easiest ways to improve your results without guessing.
7. Segmentation
This means dividing your list into smaller groups based on interests, behavior, or data.
Example:
You could send one email to people who downloaded your free guide and a different one to your paying customers.
Why it matters: Segmented emails are more relevant — and more likely to be opened and clicked.
8. Automation
Email automation lets you send emails automatically based on certain actions.
Examples:
-
A welcome email when someone signs up
-
A follow-up if someone doesn’t open your first email
-
A reminder when a cart is abandoned
Why it matters: Automation saves time and helps you stay consistent without doing everything manually.
9. Call to Action (CTA)
This is the part of your email that tells your reader what to do next — like “Download the guide,” “Shop now,” or “Book your call.”
Why it matters: A strong CTA guides your reader toward the result you want — more clicks, signups, or sales.
10. Conversion Rate Terms
This measures how many people took action after clicking — like making a purchase, signing up, or downloading something.
Why it matters: It’s the ultimate goal of most marketing emails — turning readers into customers or clients.
Bonus: “Bounce Rate”
This shows how many emails didn’t get delivered. There are two types:
-
Soft bounce: Temporary (like a full inbox)
-
Hard bounce: Permanent (like a fake or closed email address)
Why it matters: High bounce rates hurt your deliverability. Clean your list regularly to keep it healthy.
