SMS marketing is no longer the sidekick to email. For many brands, it’s becoming the main character in their customer engagement story. Yet the smartest eCommerce marketers are not choosing between the two. They are integrating email and SMS into a single, unified strategy.
With Omnisend, this is easier than ever. You can run both channels in the same platform, target the same audience with personalised offers, and make every customer touchpoint count. Let’s explore why more brands are doubling down on text and how you can make the most of it.
Why SMS Marketing Works So Well
SMS has always been a direct, personal way to reach customers. Today, its power is amplified by three big trends:
Unmatched open rates – SMS boasts up to 98% open rates, with most messages read within minutes.
Shorter attention spans – Quick, concise messages are more likely to be consumed and acted upon.
Privacy-first marketing – With stricter data privacy rules, opt-in SMS lists are now a goldmine of engaged, permission-based customers.
Unlike social media algorithms, SMS delivers your message straight into the customer’s hand. That’s why brands are using it for launches, flash sales, reminders, and even post-purchase engagement. And with most shoppers checking their phones multiple times per hour, the window for impact is almost instant.
Why Omnisend Is the Perfect SMS + Email Hub
Running your SMS and email separately can be messy. You risk duplicated messages, inconsistent branding, and fragmented reporting. Omnisend solves this by keeping both channels under one roof.
Key benefits include:
- Shared audience profiles – Keep a single customer record with all their email and SMS activity.
- Cross-channel automation – Build flows that trigger the right message on the right channel at the right time.
- Consistent brand voice – One platform means your campaigns always feel like they came from the same place.
- Unified analytics – Measure the combined impact of SMS and email in a single dashboard.
Pro Tip: With Omnisend’s segmentation, you can target customers by behaviour across both channels, for example, sending SMS only to those who opened your last email but didn’t click through.
SMS and Email Integration: The Winning Flows
Here’s where Omnisend really shines. You can layer SMS into your existing email flows or build SMS-first automations for faster results.
1. Welcome Flow
- Email: Send a detailed welcome email introducing your brand story and key products.
- SMS: A short, friendly text offering a welcome discount code for immediate engagement.
Pro Tip: Use SMS for urgency (“Your 10% off expires in 48 hours”) and email for storytelling.
2. Cart Abandonment
- Email: Send product images, benefits, and testimonials.
- SMS: A quick nudge with the direct checkout link.
Pro Tip: SMS works best within 1–2 hours of abandonment, while email can follow up later with more context.
3. Flash Sales & Product Drops
- SMS: Alert your VIP list instantly when the sale goes live.
- Email: Follow up with full product details, bundles, and upsell offers.
Pro Tip: Reserve SMS for time-sensitive deals so customers learn to act quickly when they see your texts.
4. Post-Purchase Upsell
- Email: Share how-to guides, usage tips, or product care instructions.
- SMS: Suggest a related product with a discount code for their next order.
Pro Tip: Strike while excitement is high send SMS within 3–5 days of delivery.
Crafting SMS Messages That Convert
The beauty of SMS is also its biggest challenge: you only have 160 characters. This means every word needs to earn its place.
Best practices for SMS copy:
- Lead with value (“Get early access to our winter sale”)
- Add urgency (“Ends tonight at midnight”)
- Include a short, trackable link
- Keep your tone conversational and on-brand
Example:
“Your VIP access is here! 🌟 Shop our winter sale now for 20% off sitewide. Ends midnight! [link]”
Pro Tip: Always test variations. A small tweak in wording can make a big difference in clicks and conversions.
Avoiding Common SMS Marketing Mistakes
Even with Omnisend’s tools, some brands still trip up. Here’s what to avoid:
- Over-messaging: SMS fatigue can cause unsubscribes. Keep it to high-value messages.
- Ignoring time zones: Avoid sending texts at odd hours. Omnisend’s scheduling tool can help.
- Skipping consent: Always make sure customers have opted in to receive texts.
The ROI of Omnisend SMS Marketing
When email and SMS work together, they don’t just double your reach, they multiply it. Omnisend’s own research shows brands using both see up to:
- 250% higher conversion rates than email-only campaigns
- 30% more revenue from automated flows
- 3x faster click-through rates from SMS compared to email
For example, one fashion retailer using Omnisend integrated SMS into their abandoned cart flow. In just 60 days, cart recovery revenue jumped by 42% without increasing ad spend. Another skincare brand layered SMS into their loyalty program updates, resulting in a 25% boost in repeat purchases.
