While most businesses effectively using email marketing see massive ROIs ($42 for $1 spent ), it’s usually said that a 5:1 ratio between what’s earned and what’s spent serves well as a beginning point.Â
Email marketing is able to fetch much higher ROI than other channels, for a variety of reasons:
- Email has one of the highest deliverability rate—it stands at 96%
- Email is easier to measure when the right tools are in place
- Email lends itself for great pairing with all other marketing channels (for both transactional & informational content)
- Email marketing is known to drive 9% of a website’s traffic
- 60% of shoppers have confirmed that they’ve made a purchase because of an email (contrast this with 12.5% who said the reason was social media)
So, jump in shall we?
11 Ways to Maximize Your Email Marketing ROI 1. Build a relevant email list (through segmentation) Segmentation will allow you to finetune messages, personalize offers and make recommendations in a way that shoppers feel inspired to convert—again and again!
To improve your email marketing ROI, it’s necessary to target only those who’ve shown interest in your brand and products.Â
In your segmentation efforts, create sub-groups based on browsing history, preferences and buying behavior. This makes it easier to craft precise messages and make offers that increase the chances of conversion.Â
Here are a few other to-dos to build a great email list:
Make your email opt-in prompts engaging Opt for non-intrusive pop-ups and locate them on high-intent pages like product pages for better impact, and offer sign-up forms that are quick to fill.Â
Lou & Grey, a loungewear brand, offers prompts that are easy on the eyes and uses language that’s unabrasive—one look at the way their CTAs are designed, and you’ll know they’re prioritizing one over the other!
Weed out inactive customers & subscribers regularly Check metrics like open, click-through and conversion rates to determine the extent of inaction—pick those who’ve gone quiet for a while for retargeting campaigns.Â
Get rid of hard-bounce emails & email addresses For addresses check for the frequency—if it’s repeated a few times in a row, then it’s probably invalid.Â
Look into multiple subscriptions from the same user Especially when businesses import contacts, duplications happen—ensure a user receives an email just once.Â

2. Run UX checks on content & design UX audits on content & design will tell you if customers are convinced enough to convert.Â
A/B testing will further enable you to prioritize elements that are working smoothly.Â
Here’s a checklist you can refer back to whenever you’re trying to optimize email design for improved ROI:Â
Prioritize “responsive” for mobile Mobile customers contribute to the opening of 41.6% of emails, which makes it necessary for them to be scannable, designed to adapt to various screen sizes and feature ONE prominent CTA.Â
Feature simple yet visually rich CTAs This offers direction on next steps and speeds up action, enhancing chances of conversions—well-designed CTAs also help businesses track & measure email campaigns more effectively.Â
Use subject lines that create curiosity, quickly Email subject lines that don’t exceed 10 characters, have the highest open rate of 58% .Â
A/B test important variables frequently Run tests on content variations, CTA color, size and placement, subject lines, nature of image, image placement etc.

3. Work with the right email marketing tool As your business expands and you need faster, more curated emails to sustain customer loyalty, manual emails will become difficult to manage.Â
This is when you’ll need an email marketing tool that can help you segment, automate and market great emails.Â
How do you choose a tool that will boost your email ROI?
→ One that offers a wide range of workflowsÂ
→ One that is extensively able to conduct A/B split tests
→ One that features deep analytics to identify & target shopper behavior
→ One that helps you personalize emails beyond the scope of templates
4. Identify email types to boost ROI While subscribers generally like well-designed emails, not all of them get the most opens or are even shared widely.Â
This is because not all emails are prioritized equally by your shoppers —something you’ll have to consider again and again while improving email marketing ROI.Â
While helping clients reinvent their email strategies, we’ve concluded the following emails boost ROI most rapidly:Â
Welcome emailsÂ
All great welcome emails have one thing in common: they talk straight to the needs, expectations and anticipations of their recipients.Â
This makes welcome emails inspiring enough to be opened, read through, clicked through and in the best cases, even shared.Â
Pro Tip: Set up a welcome email workflow featuring at least two and at most three emails—such a workflow can potentially generate 90% more orders than a single email!
Order confirmation emails
Almost 65% of shoppers consider order confirmation messages to be the most valuable kind to be sitting in their inbox.Â
Set expectations, use personalized language, clarify customer support information and even micro copy to make a return or issue an exchange, and you’re all set!
Cart abandonment emails
Over 40% of subscribers open cart abandonment emails—which means the more targeted they are, the more they’ll boost your email marketing ROI.Â
However, over-contacting customers through too many cart recovery emails in a row is a bad idea.Â
The ideal number : 3—space them out with two to three days between each of them!
Survey / feedback emails (that come with a reward)
Emails that solicit feedback and opinions are a lot like an honest conversation between a brand and a shopper—and this is why, when done well, they improve customer loyalty while pushing more sales.Â
Just remember:
Post-purchase emails
Now these can be just another form of order confirmation email, but not necessarily.Â
Most eCommerce businesses send just two post-purchase emails —one to confirm the order and one when the order is delivered.Â
But you can maximize ROI by sending one post-purchase email in between, just to create excitement —and if you can make a soft upsell, nothing like it.Â
5. Bring in dynamic content Along with segmenting subscribers, if you can bring in dynamic content, there’s a greater chance of seeing higher ROI.Â
In fact, research reveals this too—brands that have used dynamic content in their promotional emails have seen at least 22% increase in ROI of email marketing.Â
Drive location-based updates
Geolocation targeting is valuable because your email content becomes more relatable with this approach.Â
Talk about a store that’s opening close to the shopper—this way you can segment all those who stay close to the store (or is just a short drive away).
This is exactly why the smartest eCommerce stores ask for zip codes when asking for email sign-ups.Â
Location-based updates can also be about the weather or the season—this typically meets shoppers exactly where they are and they feel a lesser need to delay the purchase!
Feature gender-based content
This is another massive opportunity to drive your email ROI higher—segment gender based on more nuances like age group, style preferences or even new launches / clearance styles, and you’re likely to have more subscribers converting.Â
Show timed offers (that change!)
This is especially a great tactic for sending offers to long-term customers or subscribers who browse your store very often (but don’t buy.)
Creating a timed offer that changes whenever the email opens packs in more of the urgency punch—here’s an example from fashion eCommerce brand Kate Spade:
6. Incorporate social proof strategically Too much social proof or too less is a problem when it comes to email marketing ROI.Â
You wouldn’t want all your emails to carry them because it can start to seem pushy for the recipient.Â
But you would want the right emails to carry them—that too in the most strategic parts!
For example, if you know a subscriber has been browsing but not buying, it makes sense to highlight the product(s) in question and flank them with review snippets carrying real names, just like Origins does:
On the other hand, if you’re sending someone a welcome email, they would care less about what other customers are saying but will pay attention to how the founder is talking about the brand—something that Glow Recipe gets right:
Then again, if you’re targeting repeat customers who’ve been engaging with your brand for a while (by “a while,” we mean at least 6 months,) do what DermStore does:
7. Make your product recommendation emails smarter Frankly, most of your email subscribers are neck deep in messages from various brands.Â
And that means, if you have to break through the clutter and improve email ROI, you’ll have to recommend what they really, really want—and not what they just might want.Â
Focus on restock / back in stock alerts
Did they browse a certain product when it was out of stock? Or did they search for a close enough product and buy it before?Â
Either way, you can leverage restock emails like the one Kylie does (notice how it’s about just ONE product—you can even make it about a bestselling bundle):
Highlight what’s “top rated”Â
Every now and then when email subscribers aren’t sure about what to pick from your entire range of products, send them what’s trending.Â
This can be particularly beneficial in boosting ROI for customers who’ve been lying low for a bit—something Vegamour leverages in this promotional email:
Talk about what’s new on a marketplace
This helps you talk about a fresh arrival to a new store and also inform that your products are available at stores other than your own—something Hims takes full advantage of in this email:
8. Assess the effectiveness of offers Why must you replace a 10% discount with a $50 cashback?—your ROI data will tell you why.Â
Look into the following to make your email offers more compelling:
Craft offers based on motivations  Look at what drives each of your customer segments—for example, a seasoned customer might appreciate first discounted access to a product launch, while a new one may get excited when you feature on offer on their wishlisted items.Â
Use urgency & exclusivity to inspire immediate action Feature the number that’s remaining in stock, the number of people who’ve been buying the product, mention if it’s a rarely restocked item to create urgency etc.
Support offers with helpful content A 10% off on one of your hero products might sound flat to the common person—but imagine substantiating the same email communication with content that showcases while that product can make a REAL difference.Â

9. Design mobile-friendly emails If you’ve got your backend checkout flow smooth, but your emails are difficult to buy through, then your ROI will naturally suffer.Â
This is why you’ll need to ensure a number of things to make your emails mobile-friendly:
→ Use a single column as a container to pile up your images and text (this will naturally maintain an information hierarchy similar to your desktop email version.)
→ Place the most critical info between the first 300 px to 500 px of your overall email height.
→ Limit the amount of microcopy you use (as well as the number of icons—the more the takeaways, the more likely recipients will tune out.)
→ Choose solid backgrounds for images (or edit the background out to reveal a solid color like white.)

10. Automate, automate, automate! Come up with bulk & personalized email strategies backed by the power of error-free automation.Â
Here are a few aspects email automation can instantly help you with:
Post-purchase updates Create a sequence that takes the worry out of tracking delivery & fretting about shipping—given that 72% of shoppers prefer convenient delivery windows over fast shipping, this is something to include in your email marketing efforts.Â
Birthdays, anniversaries & surprises Research proves that birthday emails do wonders for customer nurturance & engagement—they get 342% more revenue per email as well as earn 179% more unique clicks.Â
Quizzes & surveys Automating quizzes & surveys based on segmentation is also a great idea—automated quizzes will ensure you’re able to match the customer’s journey and surveys will fetch you data that you can use to empower your email marketing strategy further.Â
11. Ensure the right attribution model is in place Looking at existing ROI and associated data, you’ll know if your current attribution model is falling short—you need something that’s quickly quantifiable, measurable yet error-free!
Here are a few things to consider before you swear by one attribution model or another:
Clarity on marketing goals What you’re trying to achieve through marketing and where email fits into will give some crucial answers.
Are you looking at improving customer lifetime value or is your goal more immediate conversions?
When you know what outcomes you’re looking to achieve within a period of time, you can see which attribution model offers you the depth, consistency and precision you need.Â
Customer interactions across the conversion funnel Where email comes into contact with your unique conversion funnel is a key area. What kind of touchpoints are you looking to design or refine for customers across the 5 stages of conversion?Â
This will tell you the weightage that’s to be distributed among channels and what kind of weightage email independently deserves.Â
The quantity & quality of available data When it comes to the relationship between data and attributions, it’s a bit of a chicken and egg situation. To land the right attribution model, you’ll need enough data to study.
If you don’t have a lot of data quantitatively or qualitatively, you may not be able to leverage all kinds of attribution models.Â
Attribution timeframes To lock into a timeframe for a campaign, the idea is to look at:
- The impact you want the email campaign to have
- What the typical customer journey looks like (at different stages)
- What kind of role email plays in making shoppers convert and be loyal

In eCommerce, when businesses attempt to calculate their email marketing ROI, the idea is to consider the revenue that email campaigns create and the costs that are required to run these campaigns.Â
Email marketing ROI is typically calculated as follows:
Step 1: Email Marketing Revenue - Email Marketing Costs= Net Profit
Step 2: Net Profit âž— Email Marketing Costs * 100
So, in real time, it would look something like this:
If $100, 000 is your email marketing revenue and $20, 000 is the email marketing cost, then net profit would be $100, 000 - $20, 000 = $80, 000Â
So, ROI then would be:
Net Profit âž— Email Marketing Costs * 100 = 80, 000 âž— 20, 000 *100 = 400%
What do you need to determine before calculating email marketing ROI? To calculate email marketing ROI, it’s important to look at what makes up the costs, and WHAT you count as a return.Â
In terms of revenue , a business needs to pay special attention to:
The metrics to assess campaign success
Which metrics you choose to analyze the success of your email campaigns are based on the goals you set for each campaign.Â
At Convertcart, we consider the Click Through Rate (CTR), Conversion Rate, Revenue Per Email and Return on Investment to be the most effective metrics.Â
Incremental revenue from email marketing
This is a very important factor to determine before you set about to calculate email marketing ROI.Â
Here are a few ways we’ve seen being effective in assessing incremental revenue that can be attributed to email marketing:
Use time frames for comparison: Perform A/B testing In terms of costs associated with email marketing, here are a few key areas you’ll need to look into:
- Email service provider fees
- Email marketing staff salaries
- Spends on automation tools for A/B testing, personalization etc.Â
- Segmentation & data management costs
- Spends on performance analysis & optimization
- Spends on deliverability & monitoring tools
- Content creation costs (including copywriting & design)
- Additional costs for buying templates, licenses, software etc.Â

Where does email marketing fit in marketing attribution models? ‍
Marketing attribution is an integral part of calculating an eCommerce business’ email marketing ROI.
The task of an attribution model is to assess which channels are contributing to overall conversions and in what way.Â
In terms of email marketing, the attribution models that are typically used include:Â
First click Attribution In the journey towards a successful conversion, the first click attribution gives the full credit of the conversion to the CTA the shopper first clicked on.Â
For example, a shopper first clicks on a landing page CTA and lands up on the “sale” page. However, they don’t buy immediately.Â
Two days later, they receive an email featuring a limited period sale, click on it and finally buy.Â
In first click attribution, the landing page the shopper opened in the first instance would be credited for the final conversion.Â

Last click Attribution This takes into account the last click the shopper makes before converting.Â
Let’s consider an example where a shopper steps into an eCommerce website for the first time through the brand’s “link in the bio” on Instagram.Â
Though they browse through multiple pages in this session, they eventually drop off.
A few days later, they see a Facebook carousel ad with three of the products they had seen the other day on the website.Â
They click on one of the CTAs and buy a product.Â
In last click attribution, the Facebook ad will receive the brownie points for making the shopper convert.
Custom Attribution As the name indicates, custom attribution helps eCommerce businesses apply their own subjective weightage to touchpoints as far as conversions go.Â
The weight a business ascribes to a touchpoint depends on the following:
- Rate of engagement
- Conversion rate (for each touchpoint)
- Customer feedback on CX & preferred channel
- Demonstrated customer behavior (how they interact with each channel)
- Objectives of the business
So, how does email fit into this structure?
Let’s say, social media consistently helps you get new customers and then engage them repeatedly.Â
But you’ve repeatedly found the same customers relying on your Whatsapp messages to add to cart beyond the first purchase.Â
However, you may have also seen people adding to cart after the Whatsapp messages but not buying—and buying ONLY AFTER you send them abandoned cart emails.Â
In this case, based on the factors mentioned earlier, you may want to fix 40% weight to social media, 20% to Whatsapp marketing and another 40% to email marketing.Â
Linear Attribution In a linear attribution model, an eCommerce business gives equal credit to all the channels that were in the customer’s journey up to the conversion.Â
Let’s look at an example:Â
The shopper first lands on your website through an ad on Instagram and signs up for emails.
Next, they find an email offer to make their first purchase sitting in their inbox.Â
But finally they convert, when a search enquiry they typed on Google returns the website as an ad, and they click on it.Â
In linear attribution, because there have been three touch points before the shopper became a customer, each of them will get 33.33% of weightage.Â
Position Based Attribution The assumption used in this marketing attribution is that the first click and the last click are the most important in determining conversions—it also gives secondary credit to channels that may have played a role between the first and last clicks to make the conversion happen.Â
This is why in this attribution model, a business gives 40% conversion credit to the first and last clicks and 20% divided amongst the channels in between.Â
For example, a shopper expressed interest in a product because of a Google ad but then only signed for your business newsletter.Â
Next time, they saw an Instagram ad from your business, clicked on it but didn’t convert.Â
But finally, you sent them an email with a simple message saying “Want a 15% off on a favorite you’ve been checking out?” and they converted.Â
In this case, position based attribution would give 40% weightage to the Google ad, 20% to the Instagram ad and 40% to the email.Â
Here’s what you need to do to choose an attribution model: Assess the customer journey How complex your typical shopper’s journey towards a conversion is, will be the first step to figuring out an attribution model.Â
So, let’s say your primary channel of communication is email and you’ve seen consistent conversions on your storefront through email discount announcements & offers, a first-click attribution would work well.Â
Assess the available data Both the availability and quality of data become important when you’re trying to arrive at an attribution model.Â
Typically for more complex attribution models like position based attribution, you would need access to more complex and varied data. And for this to happen multiple platforms need integration and customer data tracked in detail.Â
Focus on what you’re trying to achieve Is it to generate new leads?Â
Is it to make the most of existing email subscribers list & drive them towards conversions?Â
Or are you trying to reduce your ad spends & see if email can jump in to do most of that work?Â
What your primary business and campaign goals are will tell you how to arrive at an attribution model.Â
Research on category/industry level practices There’s also that bit about not reinventing the wheel.Â
If something has already worked for other businesses in the same category or industry, look for the “why?”

What is the most sensible way of calculating email marketing ROI? While many eCommerce businesses are continuing to go the “open and convert” way, at Convertcart, we’ve noticed ONE major flaw with this approach.Â
Insanely misleading numbers.Â
So, let’s say 100k emails are sent, of which 40k are opened, and 300 from the 40k convert (In any session on the website 7 days from opening the email) —the email send/campaign will get the credit for all 300 conversions.
This is attribution gone haywire because A LOT can happen in 7 days in terms of customer behavior and the touchpoints they access—in which case, attributing it all to email can offer attractive numbers but not let you finetune your overall ROI strategy in the long run.Â
Instead imagine the following scenario:
A shopper clicks on an abandoned cart email and lands up to find their cart waiting for them.Â
They see the brand’s making them a new offer of 15% off— the instant price drop makes them successfully checkout.Â
At Convertcart we champion this as the “CLICK & CONVERT” attribution.Â
Here’s why we’ve seen it working again and again:
- It makes measurement precise because it sticks to the SINGLE SESSION model
- It avoids measurement errors that comes with weightage % approximationsÂ
- It is HIGHLY TRANSPARENT & allows businesses to grow their email marketing strategy in a more targeted way
So, like earlier, if we have to crunch numbers, with Click & Convert attribution:
100k emails are sent, of which 40k are opened, 4k are clicked, and 100 from the 4k clicks convert in the same session —the email send/campaign will get the credit for all 100 conversions.
No confusion about how long the attribution window should be and why it should be.Â
No unnecessary attribution biases towards certain channels over others.Â
No unnecessary wait time to calculate how email is performing in REAL TIME!
No flaws when it comes to ROI data—which means better email marketing strategies in the future as well!

How is ROI data used for email marketing? The right kind of ROI data is critical for email marketing success, both in the short and long term.Â
Here’s how eCommerce businesses use ROI data to improve their email marketing efforts:
To improve campaign performance Looking at existing ROI data, you can assess the ratio between what you invested into a campaign and the returns it gave.Â
When you assess email-related metrics such as revenue per email, average order value and conversion rate, you’re better able to see which aspects of the campaign worked.Â
To allocate resources more effectively The more precise your ROI data is, the better it’ll be able to guide you with resource allocation.Â
For example, if you consistently find email marketing giving you higher ROI than other channels for 6 continuous months, you can decide to allocate more resources to it.Â
To support A/B testing efforts
When you assess ROI data, you’ll be able to better understand which aspects of an email worked for shoppers and which didn’t.Â
This can make you see patterns around well-performing subject lines, CTAs that helped convert within the same session as well as content & visual elements.Â
This is ideal for you to come up with more A/B testing ideas to put into action and build hypotheses around.Â
To decide on long-term email marketing strategy Once you begin to see the right ROI data, you’ll be able to gather a clearer picture of how to use resources for this marketing channel.Â
In addition, knowledge of what elements have repeatedly worked will help you apply them across more instances.Â
