Deep Dive Into Email Marketing
Email marketing benchmarks for DTC brands
Email marketing serves as the foundational retention channel for any online store. It allows you to send long-form content and complex visual layouts directly to buyers.
Brands use automated flows and weekly campaign broadcasts to engage their list over time. This approach builds trust and keeps your product top of mind.
The average ecommerce store generates a $0.10–$0.25 per email of its total revenue from this channel. You can expect strong performance when you segment your audience properly.
How good is a 30% email open rate for ecommerce?
Many founders ask this question when auditing their current performance metrics. An open rate around 30% is standard but often inflated by privacy updates.
Apple introduced Mail Privacy Protection (MPP) that automatically open messages in the background. This technology makes open rates an unreliable metric for measuring true engagement.
The average click rate of 1.69% provides a much better indicator of actual buyer interest. You should look at revenue per recipient instead of open rates to measure success accurately.
Founders must shift their focus toward conversion metrics and total revenue generated. Measuring clicks and placed orders gives you a clear picture of channel health.
SMS vs. email click through rates comparison
Email click rates look lower than text message rates, but the overall volume drives massive revenue. Automated email flows consistently deliver higher conversion rates than standard campaign blasts.
Text messaging generates higher click rates due to high immediate visibility. Email requires users to actively open the message and click a link inside a complex layout.
The cost to send an email remains incredibly low even at high volume. You can nurture leads for months without burning through your marketing budget.
You get a lower percentage of clicks per email, but you can afford to send many more emails. This volume advantage makes email the ultimate long-term retention tool.
Is Email or SMS marketing better ROI for DTC brands?
Email historically delivers a massive return on investment for scaling brands. The platform allows for deep storytelling that builds long-term emotional connection.
Customers expect brands to email them regularly with updates and educational content. This channel owns the customer relationship without relying on paid ad platforms.
You spend pennies to send thousands of emails to your established customer base. The low overhead creates profit margins that paid acquisition simply cannot match.
Text messaging delivers strong returns but carries a much higher hard cost. Email wins the return on investment battle purely due to its near zero marginal cost per send.
Email vs. SMS marketing ROI comparison
Email does have drawbacks regarding inbox competition and slow response times. A customer might not see your message until a day or two after you send it.
Deliverability issues can also trap your messages in spam folders if you manage lists poorly. You must constantly clean your subscriber list to maintain high placement rates.
This channel works best for brands with complex products requiring education. It fits founders who prioritize high profit margins on their retention efforts.
We recently audited an apparel brand struggling with repeat purchases. We rebuilt their post purchase email flows to educate buyers about fabric care which increased their lifetime value.
Deep Dive Into SMS Marketing
Average SMS marketing conversion rate for e-commerce
SMS marketing puts your brand directly into the text message inbox of your customers. It forces you to communicate with extreme brevity and clear calls to action.
Customers read most text messages within a few minutes of delivery. This rapid consumption makes the channel incredibly powerful for driving urgent sales.
The conversion rate hovers around 1% for standard broadcast campaigns. Automated flows perform much better and generate higher revenue per message sent.
Brands see the best conversion rates during high-urgency events like product drops. The immediacy of the channel forces the customer to make a quick buying decision.
Should ecommerce brands invest in SMS marketing?
Text messaging requires a larger budget than email due to higher carrier costs. The return on investment justifies the expense when you use the channel correctly.
Brands see high engagement when they reserve text messages for truly important updates. You must respect the intimate nature of a personal text inbox.
Sending too many text messages will ruin your list and waste your money. You need to treat this channel as a premium touchpoint for your best buyers.
The high cost forces you to segment your audience aggressively. This strict segmentation ultimately leads to better marketing habits across your entire business.
SMS vs email open rates ecommerce 2025
Comparing open rates between these two channels reveals a massive gap in visibility. Text messages boast a delivery rate near 98%.
You must remember that text message open rates actually reflect delivery rates rather than active reads. Customers see the preview text on their lock screen without opening the actual message.
The real metric to watch is the click rate which shows actual intent. High visibility makes this channel perfect for urgent product drops and VIP announcements.
When researching sms vs email open rates ecommerce you will find text always wins on raw visibility. This visibility comes at a premium price that you must manage carefully.
SMS marketing vs email marketing pros and cons
The biggest advantage of text marketing is the immediate capture of customer attention. You can launch a flash sale and see a revenue spike within minutes.
The primary drawback is the strict character limit and lack of visual formatting. You face much higher unsubscribe rates if you message your list too frequently.
Customers tolerate daily emails but they will opt out of daily text messages immediately. You must carefully balance your desire for revenue with the customer experience.
The cost structure also presents a major hurdle for brands with small margins. You must calculate your break even point before scaling your text message volume.
SMS marketing cost vs email marketing cost
Text messages cost significantly more to send on a per message basis. This higher cost forces brands to be highly strategic about segmenting their text audience.
You cannot afford to blast your entire SMS list with generic weekly updates. You must treat this channel as a premium touchpoint for your most engaged buyers.
Email platforms typically charge a flat monthly fee based on your total subscriber count. Text messaging platforms charge based on the actual number of messages you send.
This variable cost structure means your expenses scale directly with your marketing activity. You must ensure every text message campaign has a clear path to profitability.
Head-to-Head: Key Decision Factors for Email vs. SMS Marketing for Ecommerce Brands
How do ecommerce SMS and email open rates compare in 2025?
| Metric | SMS | |
|---|---|---|
|
Average open rate |
20–45% |
97–98% |
|
Average click-through rate |
10–20% |
|
|
Average conversion rate |
1–3% |
2–6% |
|
List growth speed |
Fast |
3–4x slower |
SMS wins on open rate by a margin that no email optimization can close. Email wins on list size, cost efficiency, and total revenue in automated flow contexts because the volume advantage compounds over time.
Which channel wins for abandoned cart recovery?
SMS wins on speed, and email wins on depth. An SMS sent 15–30 minutes after cart abandonment converts at 15-20% on average.
An email sent at the same interval converts at 3–5%, but an email sequence over 24–72 hours recovers more total revenue because it reaches a larger portion of your abandoning traffic.
What does email vs. SMS marketing actually cost for ecommerce brands?
A Klaviyo account with 25,000 active contacts costs around $400 per month. Scaling up to 50,000 contacts only raises the monthly price to roughly $700.
Standard text messages in 2026 run between $0.01 and $0.05 per send based on length and platform. Adding images or video turns the message into an MMS which costs between $0.03 and $0.30 per send.
That higher variable cost becomes irrelevant when the channel converts well. Spending $1,500 on text campaigns makes complete sense when it drives $25,000 in immediate revenue.
Which channel drives better ROI for DTC brands?
Email typically shows higher total revenue attribution because list sizes are larger and cost per send is lower. SMS typically shows higher revenue per message sent because of the engagement rate advantage.
Comparing them on ROI in isolation misses the real answer. Email is your long-term relationship channel and SMS is your activation channel, and they are solving different problems in the customer journey.
Klaviyo email vs. SMS: which drives more revenue?
Klaviyo released its 2025 Benchmark Report to answer whether email or SMS drives more revenue. The data shows clear differences in how both channels perform across online stores.
Standard SMS campaigns produce a slightly higher average revenue per recipient than basic email campaigns. This early advantage comes from high visibility since text messages guarantee almost total delivery.
Email takes the lead when you analyze the highest-performing stores. The top ten percent of email campaigns generate more revenue per recipient than the best SMS campaigns.
Automated flows drive the biggest returns regardless of the channel you choose. The data proves that automated sequences generate up to thirty times more revenue than standard one-time broadcasts.
SMS wins when you need immediate cash flow from a fast flash sale. Email wins when you want to build a reliable foundation for long-term customer purchases.
What is the best platform for running email and SMS together?
Klaviyo is the consensus choice for scaling DTC brands that want both channels in one platform with unified customer profiles. Postscript is the strongest SMS-only alternative for brands already satisfied with their email stack.
Attentive is the enterprise-tier SMS option for brands above $10M in revenue that need advanced segmentation and dedicated support.
Expanding Your Strategy
Building Your Subscriber Lists
You cannot market to an empty database. List growth requires deliberate effort and strong incentives.
Email list growth usually relies on a standard website pop up. Brands offer a percentage discount in exchange for an email address.
Text message list growth requires a different approach due to higher customer friction. People guard their phone numbers much more closely than their email inboxes.
You must offer a stronger incentive to capture a phone number. Many brands offer a larger discount or exclusive product access for SMS subscribers.
Two-step pop-ups work best for capturing both data points. You ask for the email first and then request the phone number on the second screen.
This method secures the email even if the customer abandons the phone number step. You build your foundational list while slowly growing your premium text list.
Segmenting Your Ideal Customer Profile
Sending the same message to everyone destroys your profit margins. You must segment your audience based on actual purchase behavior.
We build a tiered Ideal Customer Profile structure for our clients. This approach works much better than targeting broad demographics.
Your highest tier consists of repeat buyers who purchase at full price. These VIP customers deserve early access to new products via text message.
Your middle tier includes seasonal buyers and discount shoppers. You should target this group heavily with email campaigns during major promotional events.
Your lowest tier features unengaged subscribers who have never purchased. You must suppress these contacts from your expensive SMS campaigns entirely.
Proper segmentation protects your sender reputation and improves your overall metrics. It ensures you spend your marketing budget on people who actually convert.
Adapting Retention to AI Search
Search engines like Amazon A9 and Rufus are changing how customers find products. Generative Engine Optimization impacts how you should write your retention copy.
Customers now expect direct and highly relevant information immediately. Your emails must answer common product questions clearly without aggressive marketing fluff.
You can use email to educate your audience about specific use cases. This content mirrors the specific long tail queries they use in AI driven search environments.
Text messages should link directly to optimized product pages. The landing page experience must match the brevity and clarity of the text message itself.
Aligning your retention copy with your search strategy creates a seamless customer journey. It reinforces your brand authority across every touchpoint.
Compliance and Legal Guidelines
You cannot ignore the strict laws governing retention marketing. Violating these rules leads to massive fines and blocked sender accounts.
Email marketing falls under strict regulations regarding privacy and data collection. You must provide a clear physical address and an easy way to unsubscribe in every email.
Text messaging faces even stricter regulations regarding consumer protection. You must obtain explicit written consent before sending a single promotional text.
Checking a box during checkout does not always count as proper consent for SMS. You must use clear disclosure language near the phone number capture field.
You must also respect strict quiet hours for text messaging. Sending a promotional text in the middle of the night will trigger immediate complaints.
Maintaining compliance protects your business from costly litigation. It also forces you to respect your customers and build a higher quality subscriber list.
The Impact of Pricing on Channel Strategy
Product pricing directly influences which retention channel performs best. High ticket items require a completely different approach than low cost consumables.
You cannot rely solely on SMS to sell a high priced luxury item. The customer needs more information and visual proof before they spend that kind of money.
Email provides the necessary space to justify a premium price point. You can share founder stories and detailed manufacturing processes to build perceived value.
Lower priced consumable products thrive on SMS marketing. The customer already understands the value and simply needs a quick reminder to repurchase.
You must align your channel strategy with your specific pricing model. Forcing the wrong channel on your product will artificially depress your conversion rates.
Customer Acquisition Cost Reduction
Rising ad costs make paid traffic less profitable every year. You must lower your overall Customer Acquisition Cost to survive in modern ecommerce.
A strong retention program offsets the high cost of acquiring new buyers. You can afford to pay more for a customer if you know they will buy again.
Email marketing serves as your primary tool for recovering acquisition costs. The near zero send cost allows you to squeeze margin out of every subsequent purchase.
SMS marketing accelerates the payback period for your initial ad spend. A well timed text message can turn a first time buyer into a repeat customer within days.
Tracking your blended metrics gives you a complete picture of profitability. Your retention efforts should actively drive down your long term acquisition costs.
Standard Operating Procedures for Send Schedules
Consistency is the most important factor in retention marketing. You must build Standard Operating Procedures to govern your sending schedule.
We manage hundreds of SOPs to ensure our clients maintain a profitable rhythm. You cannot rely on random inspiration to drive your email and SMS campaigns.
Your email schedule should include a mix of educational content and direct promotions. You should aim for a consistent minimum of two emails per week.
Your SMS schedule requires much tighter control to prevent list fatigue. You should limit text campaigns to major holidays and highly urgent product drops.
Documenting these processes ensures your marketing team never misses a send. It removes emotion from the process and keeps your brand visible.
Creative Strategies for Text vs Email
The format dictates the creative approach you must take. You cannot simply copy your email text and paste it into an SMS platform.
Email allows for rich visual layouts and high resolution photography. You can build complex content hierarchies that guide the eye toward the buy button.
Text messaging limits you to plain text and perhaps a single image. You must rely entirely on punchy copywriting and a strong offer.
Your emails should focus on telling a compelling story. Your text messages should focus purely on creating friction free urgency.
Testing different creative angles helps you understand what resonates with your audience. You must continuously iterate on your designs and copy to prevent fatigue.
AOV and Lifetime Value Expansion
Average Order Value dictates how fast your brand can scale. Both email and SMS provide excellent opportunities to increase this critical metric.
You can use post purchase email flows to cross sell related products. Recommending a complementary item a week after delivery often yields high conversion rates.
Text messaging works incredibly well for limited time bundle offers. You can text your VIP list an exclusive link to purchase a high value product kit.
Focusing on Lifetime Value transforms your business from a transactional store into a brand. Retention marketing is the only reliable way to drive this metric upward.
Every dollar you invest in these channels compounds over time. Your list becomes a proprietary asset that generates predictable cash flow on demand.
Deliverability and Sender Reputation
Getting an email into the primary inbox requires ongoing technical maintenance. You cannot simply press send and assume the customer will see it.
Internet service providers constantly monitor your sender reputation. They will route your messages to the spam folder if you receive too many complaints.
You must actively prune your email list to remove unengaged contacts. Sending messages to people who never open them destroys your deliverability scores over time.
Text messaging does not suffer from traditional spam folders. Carrier networks will completely block your number if you violate their sending policies.
You must monitor your bounce rates closely on both platforms. A sudden spike in hard bounces usually indicates a critical problem with your list hygiene.
Protecting your sender reputation ensures your marketing messages actually reach your buyers. It is the invisible foundation of a profitable retention program.
Holiday Season Strategy for Both Channels
Black Friday and Cyber Monday require a completely different approach to retention. The sheer volume of marketing messages forces brands to fight aggressively for attention.
Your email strategy must start weeks before the actual holiday weekend. You should use early November to educate your list and tease upcoming promotions.
During the actual holiday weekend you should increase your email sending frequency dramatically. Sending two emails per day is completely acceptable during peak shopping events.
Text messaging becomes your secret weapon during the final hours of a sale. A text message sent four hours before a promotion ends will drive massive last minute revenue.
You must secure your sending limits and platform approvals well before November. Waiting until the last minute will result in delayed campaigns and lost sales.
A coordinated dual channel strategy maximizes your revenue during critical shopping periods. It ensures your best offers break through the intense holiday noise.
Handling Opt Outs and List Churn
Every marketing channel experiences a natural rate of subscriber churn. You should expect a small percentage of people to unsubscribe after every campaign.
An unsubscribe is actually better than a spam complaint for your long term health. It gracefully removes a person who is no longer interested in your product.
You should monitor your opt out rates to gauge the quality of your content. A sudden spike indicates that your messaging was either too frequent or irrelevant.
Text message opt outs happen much faster than email unsubscribes. Customers will text STOP the exact moment they feel annoyed by your frequency.
You must replace these lost subscribers continuously to maintain baseline revenue. Your lead generation efforts must run constantly to offset this natural churn.
Accepting churn as a normal part of business prevents emotional decision making. It forces you to focus on acquiring high quality leads who actually want to hear from you.
Analyzing Heatmaps and Click Data
You must look beyond high level metrics to truly understand customer behavior. Analyzing exactly where people click reveals massive optimization opportunities.
Email platforms often provide heatmap reports for your campaign sends. These reports show which images and links receive the most attention from your readers.
You will often find that text links perform better than large graphic buttons. This data allows you to simplify your email designs and focus on what actually works.
Text messaging offers fewer data points but link tracking remains critical. You must use unique tracking links to attribute revenue accurately to your SMS campaigns.
Reviewing this data monthly helps you refine your creative approach over time. You stop guessing what the customer wants and start building strategies based on actual behavior.
Data driven marketing eliminates wasted effort and maximizes your return on investment. It turns retention marketing from an art into a predictable science.

Frequently Asked Questions
Should I use email or SMS marketing for my online store?
Use both if you are above $1M in annual revenue. Start with email to build your list and automate your core flows, then add SMS once email is generating consistent retention revenue.
What are normal SMS vs. email open rates for ecommerce?
Email open rates between 20–35% are normal for broadcast campaign sends, while automated flows regularly hit 40–60%. SMS open rates run 97–98% regardless of send type.
How often should I send SMS vs. email to my customers?
Send email two to four times per week to your engaged segments. Limit SMS campaign sends to two to four times per month, since higher frequency accelerates opt-out rates significantly and those opt-outs are permanent.
What is the average SMS marketing conversion rate for ecommerce?
SMS campaign sends average 2–4% conversion. SMS flows like abandoned cart and back-in-stock alerts regularly convert at 8–15% because the timing is tied to a high-intent customer action rather than a scheduled broadcast.
Is SMS marketing cost-effective compared to email for ecommerce?
Yes, when send frequency is managed correctly. The higher cost per message is offset by higher engagement and conversion rates for brands that treat SMS as a high-intent, low-frequency channel rather than a broadcast vehicle.
