Email + SMS marketing: a winning combination for e-com growth

In the fast-paced world of e-commerce, staying connected with your customers is essential to driving sales and fostering loyalty. As an online retailer, you have many marketing channels at your disposal, but two powerhouses stand out: email and SMS marketing. These tried-and-true strategies have proven their worth time and again, but what happens when you combine them? 

In this post, we'll explore how integrating email and SMS marketing can supercharge your e-commerce sales and take your business to new heights. Platforms like Klaviyo, Justuno, and Yotpo offer robust features to help you achieve this synergy. Here’s what you should know.

The powerhouses: email & SMS marketing

Email marketing

Email marketing has been a staple in the e-commerce marketer's toolkit for years. It involves sending targeted, personalized messages to your subscribers' inboxes to promote your products, share valuable content, and nurture customer relationships. With an impressive ROI of $42 for every $1 spent, it's no wonder that email remains a go-to channel for online retailers.

SMS marketing

SMS, or text message marketing, has emerged as a highly effective way to reach customers on their most personal devices. By sending short, timely messages directly to your customers' phones, you can grab their attention, drive urgency, and inspire action. SMS boasts open rates as high as 98%, making it a powerful complement to your email campaigns.

Benefits of email marketing for e-commerce

Here's how email marketing can be your e-commerce superpower:

Direct communication channel

Email marketing provides a direct line of communication with customers. Unlike social media, where algorithms control visibility, emails go directly to their inbox, ensuring your message is seen by your recipient.

High return on investment (ROI)

Email marketing offers a high ROI. For every $1 spent, the average return is $36, making it a cost-effective marketing strategy. This high ROI is due to the low cost of email campaigns compared to other marketing channels.

Personalization and segmentation

Emails can be highly personalized and segmented based on customer behavior, preferences, and purchase history. This allows for tailored messaging that resonates with individual customers, increasing engagement and conversion rates​​​​.

Customer retention and loyalty

Email marketing is instrumental in retaining customers and fostering loyalty. Regular communication through emails keeps your brand at the forefront of customers' minds and encourages repeat purchases. Loyalty programs integrated with email marketing can enhance this effect by rewarding customers for their ongoing engagement​​​​.

Driving traffic to your website

Emails can drive significant traffic to your e-commerce site. Including links to your products, blog posts, and landing pages in your emails encourages recipients to visit your site, explore your offerings, and make purchases.

Measurable results

Email marketing platforms provide comprehensive analytics that help track the success of campaigns. Metrics such as open rates, click-through rates, conversion rates, and unsubscribe rates offer valuable insights into customer behavior and the effectiveness of your strategies​​​​.

Automation capabilities

Automation in email marketing allows you to send timely and relevant messages based on customer actions. Automated emails, such as welcome series, abandoned cart reminders, and post-purchase follow-ups, promote continuous engagement without manual effort​​​​.

5 Steps of email marketing

Benefits of SMS marketing for e-commerce

SMS marketing brings its own set of powerful benefits to the table:

  • High open rates: SMS messages boost significantly higher open rates compared to emails, often exceeding 90%. This ensures that your message is almost always seen by the recipient, making it an effective way to deliver important information quickly.
  • Immediate delivery and engagement: SMS marketing allows you to reach your customers almost instantly. Most people read text messages within minutes of receiving them, which is ideal for time-sensitive promotions, flash sales, or urgent updates.
  • Direct and personal communication: Text messages create a direct and personal line of communication with your customers. The intimate nature of SMS makes recipients feel valued and more likely to engage with your brand.
  • Cost-effective marketing: SMS marketing is relatively inexpensive compared to traditional advertising methods. With a lower cost per message, it’s an affordable way for businesses to reach a large audience, making it accessible for companies of all sizes​​.
  • Enhanced customer retention: SMS marketing can help retain customers by providing regular updates, exclusive offers, and personalized content. This continuous engagement keeps your brand top-of-mind and encourages repeat purchases​​.
  • Integration with other marketing channels: SMS marketing can be seamlessly integrated with other marketing strategies such as email, social media, and loyalty programs. This multi-channel approach facilitates a cohesive customer experience and maximizes the reach and impact of your marketing efforts​​​​.
  • Opt-in marketing: SMS marketing is an opt-in channel, meaning customers have actively chosen to receive messages from your brand. This level of consent typically results in a more engaged and receptive audience, improving the effectiveness of your campaigns.
  • Reduced risk of spam: Unlike email marketing, SMS messages are less likely to be filtered out as spam. This means your messages are more likely to reach the intended recipients without being lost in cluttered inboxes.

Benefits of combining email and SMS marketing

When you integrate email and SMS marketing, you create a powerful synergy that amplifies the strengths of each channel. Here are some key benefits of this dynamic duo:

Increased reach: By leveraging both email and SMS, you can connect with a wider audience and ensure your messages are seen.

Enhanced engagement: Combining the in-depth content of email with the immediacy of SMS keeps customers engaged and drives higher response rates.

Improved segmentation: With data from both channels, you can create more targeted segments and deliver hyper-relevant messages.

Boosted retention: A multi-channel approach helps you build stronger customer relationships and increase lifetime value.

Maximized ROI: By optimizing your email and SMS campaigns based on performance data, you can achieve a higher return on your marketing investment.

Platforms like Klaviyo offer seamless integration of email and SMS marketing, making it easy to harness the power of both channels.
