Marketing metrics: What to measure across email, SMS and social

It’s easy to get bogged down in the numbers. While it might seem like the done thing to trawl through every fact and figure your marketing tools can provide, you don’t need to track every metric under the sun.

Instead, focus on the handful of marketing metrics that tell you what really matters: whether people are paying attention, taking action and sticking around.

If you’re running a multi-channel marketing strategy, things get a little more complicated. Each channel has its own metrics and its own idea of what “good” looks like. Before you know it, you’re up to your eyeballs in data, with very few useful answers to show for it.

In this guide, we’ll cover the key marketing metrics worth tracking across email, SMS and social media, what each one actually tells you, and how to bring the numbers together so you can make better decisions about your next campaign.

What are marketing metrics?

Marketing metrics help you understand how your marketing is performing. They can tell you how many people saw your campaign, how many engaged with it, how many took the action you wanted and whether your audience is growing or dropping away.

The right marketing metrics depend on what you're trying to achieve. There's no single number that tells you whether a campaign was successful.

For most small business campaigns, the important marketing metrics fall into three areas:

• Awareness: getting your name in front of more of the right people
• Engagement: getting people to read, click, reply or share
• Conversion: getting people to buy, book, sign up or come back

There are also channel health metrics, such as email bounces and SMS opt-outs, that help you understand whether your audience and campaigns are in good shape.

If your goal is awareness, reach and audience growth matter. If it's conversion, a post with thousands of likes and no sales isn't necessarily a win.

Start with your goal, then choose the marketing metrics that show whether you're getting there.

Define your goals before tracking marketing metrics

Before you look at a single report, decide what success means for the campaign in front of you.

Because let’s face it: A metric is only useful if it connects to a goal.

For example, if you're launching your business to a new audience, you might focus on reach, impressions and audience growth. If you're promoting a limited-time offer, clicks and conversions are likely to matter more.

This simple approach stops you from measuring everything simply because your marketing platform makes the numbers available.

Email marketing metrics to track

Email marketing is usually the channel with the most data behind it, which makes it the easiest place to get distracted.

However, these are the key email marketing metrics you really ought to keep an eye on.

Open rate

Open rate is the percentage of recipients recorded as opening your email. It's a useful directional signal for how your subject line and sender information are performing.

Treat it as a guide rather than a hard fact, though. Privacy features in some email apps can affect how opens are recorded, so open rate isn't a perfect measure of whether someone actually read your email.

Use open rate to compare your own campaigns over time, alongside stronger action-based metrics such as clicks and conversions.

Click rate

Click rate shows the percentage of recipients who clicked at least one link. It's one of the clearest signs that your content and call to action encouraged someone to take the next step.

It also helps to look at which links got clicked. If everyone clicks the image at the top and nobody reaches the button at the bottom, that tells you something about your layout and what people find most compelling.

Conversion rate

Conversion rate tells you how many people went on to complete the action you wanted, whether that's buying, booking or registering.

It's the metric that links your email to real business results, so it's worth setting up site tracking to see what happens after someone clicks.

Email bounce rate

Email bounce rate tells you how many emails couldn’t be delivered.

A rising bounce rate indicates your list needs cleaning, and ignoring it can affect your sender reputation and your ability to reach the inbox.

Keep an eye on both the overall trend and any sudden changes after a particular campaign or list import. A spike in bounces after importing new contacts, for example, could indicate that some of the data is outdated or inaccurate.

If you’re looking to keep your bounce rate low, building a clean, high-quality email list is a good place to start.

Our guide to building a quality email marketing data pool covers the best practices and steps to follow.

Unsubscribe rate

Some unsubscribes are normal and can even help keep your list healthy. A sudden spike after a particular campaign, though, is worth paying attention to.

It could point to the wrong message, the wrong audience or too many emails being sent in a short space of time.

Our guide to segmentation and personalization explains how these approaches can help you deliver more relevant messaging to your target audience, which can help reduce unsubscribe rates.

Replies

Replies are easy to overlook, but they're one of the clearest signs that someone is willing to engage directly with you.

If your emails invite a response, track how many people actually reply and pay attention to what they tell you. The qualitative feedback in those replies can be just as useful as the number itself.

SMS marketing metrics to track

SMS marketing is different from email because there's no traditional open rate to rely on. That means SMS marketing metrics tend to focus more heavily on delivery, engagement and the action someone takes after receiving a message.

Delivery rate

Delivery rate shows the percentage of messages that were successfully delivered to recipients.

It's useful for monitoring list quality and technical delivery, but it doesn't tell you whether someone actually read the message.

If delivery rates drop, check for incorrect or outdated numbers in your list. Clean data matters even more here because every message you send has a cost.

Click-through rate

If your text includes a link, click-through rate is one of your clearest engagement metrics.

SMS gives you very little space, so a low click rate can be a sign that the offer or the reason to tap wasn't clear enough.

Keep the message short and make the next step obvious.

Conversion rate

Conversion rate tells you how many recipients completed the action you wanted.

SMS can work particularly well for time-sensitive offers, reminders and other messages where timing matters. Compare conversion rates across different types of SMS campaigns to see which ones are generating meaningful results.

Opt-out rate

Opt-out rate shows how many people unsubscribe from your SMS marketing, for example by replying STOP where that mechanism is used.

Texts feel personal, so people may be quick to opt out if they feel spammed. A rising opt-out rate is a useful signal to review how often you're sending messages and how relevant they are to the people receiving them.

Replies

If you invite people to text back, track how many do and what they say.

Replies turn a one-way broadcast into a conversation, and they can give you useful feedback you wouldn't get from clicks alone.

Social media metrics to track

Social media has no shortage of numbers, and plenty of them can be vanity metrics.

A post can look popular without doing much for your business. The most useful social media metrics are the ones that connect directly to what you're trying to achieve.

Impressions and reach

Impressions count how many times your content was shown. Reach counts the number of people who saw it.

Together, these metrics help you understand how far your content is travelling, which is particularly useful for awareness campaigns.

Engagement rate

Engagement rate measures interactions such as likes, comments, shares and saves relative to an audience measure such as reach, impressions or followers.

The exact calculation varies between social platforms, so make sure you're comparing like with like.

Comments and shares can provide particularly useful signals because they involve more active participation and can help content reach additional people.

Clicks

If you're using social media to drive traffic, clicks are an important metric to watch.

They show whether your post gave people a reason to find out more, and they're the bridge between social activity and what happens on your website.

Follower growth

Follower growth shows whether your social audience is increasing or decreasing over time.

Look at the trend over weeks and months rather than day-to-day, and watch for spikes after specific posts so you can identify what may have driven new followers.

Follower growth is most useful when you're also looking at the quality and engagement of the audience you're attracting.

Conversions from social media

This is where social media can get harder to measure.

Use tracked links or unique offer codes so you can see which sales, sign-ups or bookings started through social.

Without this, it's easy to undervalue or overvalue the time you spend there.

Which marketing metrics should you track?

You don't need to track every metric available in every marketing platform.

The best marketing metrics help you answer a specific business question.

Here's a simple way to match the right metric to your goal:

You don't need to track everything in the table for every campaign. Choose the three to five marketing metrics that best match what you're trying to achieve.

How to measure marketing across channels

Looking at each channel on its own only tells you part of the story.

Your customers don't think in channels.

They might see a post on Instagram, open an email a few days later and buy after a text reminder. The real insight comes from looking at how your channels work together.

Compare like with like

An SMS click rate and an email click rate aren't directly comparable. The channels work differently, and people use them in different moments.

Instead of ranking one channel against another, compare each campaign against your own past results on the same channel.

That gives you a much more useful benchmark and helps you spot genuine changes in performance.

Look for patterns across campaigns

When you run the same message across email, SMS and social, check where people engaged and where they converted.

You might find social is particularly useful for getting attention, email helps people consider the offer and SMS prompts action.

That tells you how your channels may work together and can help you plan your next campaign.

Remember that the channel that gets the final click isn't necessarily the only channel that influenced the conversion. Use your tracking data to understand the journey rather than assuming every sale belongs entirely to the last interaction.

Test, learn and repeat

Marketing metrics are most useful when you act on them.

Try one change at a time, like a new subject line, a shorter text or a different time to post, then see what moves.

Small, regular improvements add up much faster than a big overhaul once a year.

Keep your marketing reporting manageable

You don't need a complicated reporting setup to get started.

Pick three to five marketing metrics that match your goal, check them after every campaign and write down what you learned.

For example:

1. Choose the goal - awareness, engagement or conversion.
2. Pick the metrics - select the numbers that show progress towards that goal.
3. Measure the campaign - record the results consistently.
4. Compare with previous campaigns - look for meaningful changes rather than isolated numbers.
5. Make one improvement - test a change and measure what happens nextMarketing metrics: a quick checklist

Before you finish analysing a campaign, ask:

• Did we measure the metric that matches our main goal?
• Did people engage with the campaign?
• Did they take the action we wanted?
• Did the campaign generate conversions or other meaningful results?
• Did our audience grow, shrink or stay the same?
• Were there any warning signs, such as email bounces or SMS opt-outs?
• What should we change or test next time?

This gives you a simple way to turn marketing data into decisions rather than simply collecting numbers.
