How to Set Up Omnisend for Shopify: The Complete Step-by-Step Guide for E-Commerce Store Owners in 2026

Why Omnisend Is a Top Choice for Shopify Email and SMS Marketing

Omnisend is one of the best email marketing platforms for Shopify store owners, especially if you want to combine email and SMS marketing in one unified platform. I have been building and managing high-ticket dropshipping stores for over 15 years, and Omnisend is one of the platforms I consistently recommend alongside Klaviyo for e-commerce.

What makes Omnisend stand out is its multi-channel approach. While most email platforms treat SMS as an add-on, Omnisend builds email, SMS, push notifications, and web push into one seamless workflow builder. This means you can create a single automation that sends an email first, follows up with an SMS if the email is not opened, and adds a push notification as a final touchpoint. For e-commerce stores trying to maximize every customer interaction, that is really powerful.

In this guide, I am going to walk you through the entire process of setting up Omnisend for your Shopify store. We are covering everything from installation to your first automated workflows. At E-Commerce Paradise, we use this same process when building stores for our clients, so you know it works. Let’s get into it.

Step 1: Creating Your Omnisend Account and Installing the Shopify App

Getting started with Omnisend is straightforward. Head to the Omnisend website or find the Omnisend app directly in the Shopify App Store. I recommend going through the Shopify App Store because it makes the installation and authorization process seamless.

Installing From the Shopify App Store

In your Shopify admin, go to Apps and search for Omnisend. Click Add App and follow the authorization prompts. Omnisend will request access to your products, customers, orders, and checkouts. Approve all the requested permissions because Omnisend needs this data to power its automations, segmentation, and product recommendations.

Once installed, Omnisend will guide you through an initial setup wizard that walks you through the basics: connecting your store, choosing your plan, and setting up your sender information. The free plan includes up to 250 contacts and 500 emails per month, which is enough to get started and test the platform. As your list grows, you can upgrade to the Standard plan (starting around $16 per month) or the Pro plan which includes SMS credits.

Initial Data Sync and Store Connection

After installation, Omnisend automatically syncs your existing customer data, order history, and product catalog from Shopify. This sync usually completes within a few minutes for smaller stores and up to a few hours for stores with large product catalogs or extensive order history. Wait for the sync to complete before setting up your automations so all your historical data is available for segmentation.

You can verify the sync status in Omnisend’s dashboard under Store Settings. Make sure the product count, customer count, and order count match what you see in your Shopify admin. If numbers look off, try disconnecting and reconnecting the integration, which usually resolves sync issues.

Step 2: Configuring Your Sender Information and Authentication

Before you send any emails, you need to configure your sender information and authenticate your sending domain. This is critical for deliverability and is not something you should skip.

Setting Up Your Sender Details

In Omnisend, go to Store Settings, then Sender Information. Enter your store name as the sender name and use your business email address as the sender email. Make sure the email address uses your store domain (not a Gmail or Yahoo address) because this looks more professional and helps with deliverability.

Set your physical business address in the sender settings as well. This is required by CAN-SPAM law and will appear at the bottom of your emails. If you are a home-based business and do not want to use your home address, consider using a registered agent service like Northwest Registered Agent to provide a business address for your correspondence.

Authenticating Your Domain

Domain authentication tells inbox providers that Omnisend is authorized to send emails on behalf of your domain. In Omnisend, go to Store Settings, then Sender Domains, and add your domain. Omnisend will generate DNS records (DKIM and SPF) that you need to add to your domain registrar’s DNS settings.

Copy the DKIM and SPF records from Omnisend and paste them into your DNS management panel (GoDaddy, Namecheap, Cloudflare, or wherever your domain is registered). After adding the records, click Verify in Omnisend. According to DMARC.org, proper email authentication significantly improves inbox placement, so do not skip this step.

Step 3: Building Your Signup Forms and Popups

Omnisend comes with a powerful built-in form builder that makes creating signup popups, embedded forms, and landing pages easy. You need these to capture email addresses and grow your list.

Creating a Popup Signup Form

In Omnisend, go to Forms and click Create Form. Choose a popup template from Omnisend’s template library. They have dozens of pre-designed templates optimized for e-commerce, including options with discount code offers, free shipping offers, and newsletter signups.

Customize the design to match your brand: update the colors, fonts, images, and copy. Offer a compelling incentive for signing up. For high-ticket stores, I usually recommend free shipping or a small percentage discount (5-10%) rather than a flat dollar amount, because the perceived value of percentage discounts scales with the product price.

Set the popup to trigger after 15-20 seconds on site or on exit intent. Omnisend lets you control the timing, frequency (how often it shows to the same visitor), and targeting (show on all pages or specific pages). I recommend showing the popup on all pages except the checkout page, where popups can disrupt the purchase process.

Adding SMS Opt-In to Your Forms

One of Omnisend’s biggest advantages is the ability to collect SMS consent right alongside email signups. You can add a phone number field to your popup with a checkbox for SMS consent. This is important because you need explicit consent before sending SMS marketing messages.

Keep the phone number field optional so you do not reduce your form conversion rate. Some people will give you their email but not their phone number, and that is fine. Collecting SMS consent upfront from those who are willing gives you an additional channel to reach them from day one.

Step 4: Setting Up Your Essential Automation Workflows

Omnisend calls their automated email sequences “Automation Workflows.” These are triggered by customer actions and run automatically. Omnisend has pre-built workflow templates for all the essential e-commerce automations, which makes setup fast.

Welcome Series Workflow

Go to Automations and click Create Workflow. Select the Welcome Series template. Omnisend provides a pre-built welcome workflow that you can customize with your brand messaging, product images, and incentive offers.

I recommend setting up five to seven emails over 14 days. Your first email delivers the signup incentive immediately. Subsequent emails introduce your brand, showcase social proof, provide educational content, and culminate in a purchase offer. The multi-channel advantage of Omnisend means you can add an SMS message to your welcome series alongside the emails, giving new subscribers a text reminder about their discount code on day two or three.

For the complete welcome series strategy, check out our guide on how to create a welcome email series that converts.

Abandoned Cart Workflow

Select the Abandoned Cart template from Omnisend’s automation library. This is your highest ROI automation and should be the first thing you set up after your welcome series. Omnisend’s abandoned cart workflow automatically includes the product image, name, and price from the abandoned cart, making the emails feel personalized.

Set up three to four touchpoints: email at one hour, email at 24 hours with an SMS follow-up, and a final email at 48-72 hours. The combination of email and SMS in the abandoned cart workflow is where Omnisend really shines compared to email-only platforms. For the full abandoned cart strategy, read our guide on writing abandoned cart emails.

Browse Abandonment Workflow

The browse abandonment workflow targets visitors who viewed products but did not add anything to their cart. In Omnisend, create a new workflow using the Product Abandonment template. Set the trigger to activate when someone views a product page and does not take further action within four to six hours.

These emails should be softer than your cart recovery emails since the visitor showed interest but did not commit to the cart. A simple “Still looking at

?” with the product image and a link back to the product page is effective. One to two emails is sufficient for this workflow.

Post-Purchase Follow Up Workflow

Create a post-purchase workflow that triggers after someone places an order. This workflow should include a thank you email immediately after purchase, a shipping confirmation when the order ships, a review request 7-14 days after delivery, and a cross-sell recommendation 21-30 days later.

Omnisend integrates with Shopify’s order and fulfillment data, so shipping triggers are automatic. The review request email is particularly important because reviews build the social proof that helps convert future customers. Include direct links to your Trust Pilot or Google Business Profile pages to make leaving a review easy.

Step 5: Creating Your First Email Campaign

Automation workflows run in the background, but you also need to send regular campaigns to stay top of mind with your subscribers. Campaigns are one-time sends for promotions, product launches, and newsletters.

Designing Your Campaign Email

In Omnisend, go to Campaigns and click Create Campaign. Choose Email as the channel type. Omnisend’s drag-and-drop email editor is really intuitive and comes with e-commerce-specific content blocks like Product Picker, which automatically pulls product images, titles, and prices from your Shopify catalog.

Start with one of Omnisend’s e-commerce templates and customize it with your brand colors, logo, and messaging. Use the Product Picker block to add featured products without having to manually upload images or create links. This saves a ton of time, especially for weekly promotional emails where you are featuring different products each time.

Scheduling and Sending

Omnisend provides send time optimization that analyzes your subscriber data to suggest the best time to send for maximum engagement. I recommend using this feature, at least initially, until you have enough data to determine your own optimal send times through testing.

Start with one to two campaigns per week and scale up as your list grows. Consistency matters more than frequency at this stage. Your subscribers need to get used to hearing from you regularly before you increase the cadence.

Step 6: Setting Up SMS Marketing

If you chose Omnisend partly for its SMS capabilities, now is the time to set it up. SMS marketing has significantly higher open and click rates than email, making it a powerful complement to your email strategy.

Getting Your SMS Sender Number

Omnisend provides a shared sender number by default, but I recommend getting a dedicated sender number for your brand once your SMS list grows. In Omnisend, go to SMS Settings and follow the setup process for your country. For US-based stores, you will need to register a phone number and comply with TCPA regulations.

Building Your SMS Subscriber List

You can collect SMS subscribers through your Omnisend popup forms (with the phone field enabled), through a dedicated SMS signup keyword, or at checkout by adding an SMS opt-in checkbox. Make sure every SMS collection point clearly states that subscribers are opting in to receive marketing text messages, as compliance is strictly enforced.

Adding SMS to Your Automation Workflows

The easiest way to start with SMS is to add SMS touchpoints to your existing automation workflows. In each workflow, you can add an SMS message alongside or after email messages. For abandoned cart recovery, send an email at one hour and follow up with an SMS at two hours if the email has not been opened. According to Shopify’s research on SMS marketing, SMS messages see open rates above 90%, making them an incredibly effective channel for time-sensitive communications like cart recovery.

Step 7: Configuring Segments for Targeted Campaigns

Omnisend provides both pre-built and custom segmentation. The pre-built segments are ready to use out of the box and cover common e-commerce use cases.

Using Omnisend’s Pre-Built Segments

Omnisend automatically creates segments for high-value customers, at-risk customers, new subscribers, active customers, and more. These segments update dynamically based on customer behavior, so they always reflect your current data. Start by using these pre-built segments for your campaigns and customize them as you learn more about your audience.

Creating Custom Segments

For more targeted campaigns, create custom segments based on specific criteria. For example, segment by product category browsed, average order value, purchase frequency, geographic location, or email engagement level. Omnisend’s segment builder lets you combine multiple conditions with AND/OR logic to create highly specific audiences.

Step 8: Monitoring Your Performance

Omnisend’s reporting dashboard gives you a clear picture of how your email and SMS marketing is performing. Take time to understand the key metrics and check them regularly.

Key Metrics to Watch

Monitor your overall revenue from email and SMS, open rates, click rates, conversion rates, and unsubscribe rates. Omnisend attributes revenue to specific workflows and campaigns so you can see exactly which emails are generating sales. This attribution data is invaluable for deciding where to focus your optimization efforts.

I recommend checking your Omnisend dashboard weekly. Look at your workflow performance (especially abandoned cart recovery rate) and compare campaign performance week over week. If you notice declining open rates, it might be time to clean your list or adjust your subject line strategy.

Common Omnisend Setup Mistakes to Avoid

Here are the most common mistakes I see when store owners set up Omnisend, based on my experience through our coaching program.

Skipping Domain Authentication

Just like with any email platform, failing to authenticate your domain means your emails are more likely to end up in spam. Take the time to add the DNS records during initial setup. For a deep dive into authentication and deliverability, read our complete guide on improving email deliverability.

Not Using the Multi-Channel Features

If you set up Omnisend but only use it for email, you are paying for multi-channel capability without using it. The whole point of choosing Omnisend is the ability to combine email, SMS, and push notifications in unified workflows. If you only need email, a platform like MailerLite or GetResponse might be more cost-effective.

Not Customizing the Pre-Built Workflows

Omnisend’s pre-built workflow templates are great starting points, but they are designed to be generic. Customize every email with your brand voice, product imagery, specific offers, and unique selling points. Generic templates underperform personalized content every time.

Ignoring SMS Compliance

SMS marketing has strict compliance requirements under TCPA (for US) and similar regulations internationally. Make sure every SMS subscriber has explicitly opted in, include your business name in every text, provide an easy way to opt out, and never send texts outside of appropriate hours. Non-compliance can result in serious fines.
