Common Omnisend Mistakes Brands Make & How to Fix Them

If you’re using Omnisend for your ecommerce email marketing, you’re already ahead of brands stuck with clunky, generic email tools. But even the most user-friendly platforms come with a learning curve — and small missteps can tank your open rates, hurt your ROI, and waste hours of work.

According to Omnisend’s 2024 Ecommerce Email Marketing Benchmark Report, brands that use basic segmentation see 30% higher open rates than those that blast generic campaigns to their entire list. Avoid these 7 common Omnisend mistakes to get the most out of your email marketing budget.

1. Skipping Audience Segmentation

The most common Omnisend mistake we see? Brands blasting identical campaigns to their entire subscriber list. This ignores the fact that a first-time visitor has completely different needs than a repeat customer who buys from you monthly. Generic blasts lead to higher unsubscribe rates, lower engagement, and wasted send quota.

How to Fix It

• Use Omnisend’s native segmentation tools to group subscribers by purchase history, engagement level, location, and browsing behavior.
• Create targeted segments for high-value customers, lapsed buyers, and new subscribers to send hyper-relevant content.
• Set up dynamic content blocks in emails to show different products or offers to different segments automatically.

2. Overcomplicating Email Automations

Omnisend’s automation workflows are a huge selling point — but many brands go overboard. We’ve seen stores set up 20+ overlapping automations with conflicting triggers, like sending two separate abandoned cart emails 10 minutes apart. This confuses subscribers and hurts your sender reputation.

How to Fix It

• Audit all active automations every quarter to remove redundant, outdated, or conflicting workflows.
• Stick to 5 core automations to start: welcome series, abandoned cart, browse abandonment, post-purchase follow-up, and win-back for lapsed customers.
• Use Omnisend’s visual workflow builder to map out triggers and delays clearly before activating new automations.

3. Ignoring Omnisend’s Pre-Built Templates

Building every email from scratch wastes hours of design time, and amateur designs can hurt your brand credibility. Many brands don’t realize Omnisend offers hundreds of pre-built, mobile-optimized templates specifically for ecommerce use cases.

How to Fix It

• Browse Omnisend’s template library for campaigns, automations, and promotional emails that match your brand’s needs.
• Customize templates with your brand’s logo, brand colors, and product images in minutes using the drag-and-drop editor.
• Save your customized templates as defaults to speed up future campaign creation.

4. Neglecting Mobile Optimization

Over 60% of emails are opened on mobile devices, but many brands still send emails with tiny fonts, hard-to-click buttons, and layout issues that break on small screens. Omnisend’s mobile preview tool is free to use, but most brands skip it entirely.

How to Fix It

• Always use Omnisend’s mobile preview feature before sending any campaign or automation email.
• Keep email copy short (under 200 words per section) and use large, tappable CTA buttons (at least 44×44 pixels).
• Avoid using too many images or complex layouts that may not render properly on older mobile devices.

5. Forgetting to Test Campaigns Before Sending

Nothing hurts your brand’s credibility like a typo in a subject line, a broken product link, or a discount code that doesn’t work. Yet many brands hit “send” on campaigns without any testing, assuming everything is set up correctly.

How to Fix It

• Use Omnisend’s test send feature to send drafts to internal team members across different email providers (Gmail, Outlook, Apple Mail).
• Run A/B tests on subject lines, send times, and CTA copy for every major campaign to improve performance over time.
• Double-check all links, discount codes, and product inventory before activating any automation or campaign.

6. Underusing Omnisend’s Analytics Dashboard

Omnisend provides detailed, ecommerce-specific analytics — including revenue per email, conversion rates, and top-performing products — but many brands only check their open rates. This means they miss out on insights that could double their email ROI.

How to Fix It

• Set aside 30 minutes every week to review your Omnisend analytics dashboard, focusing on conversion rate and revenue per campaign.
• Tag your campaigns and automations clearly to track performance of specific promotions or product lines.
• Use performance data to pause low-performing workflows and double down on high-converting segments and automations.

7. Improper Ecommerce Store Syncing

If your Omnisend account isn’t syncing correctly with your Shopify, WooCommerce, or BigCommerce store, you’ll end up with outdated customer data, missing product images in emails, and broken abandoned cart workflows. This is one of the most frustrating (and fixable) Omnisend mistakes we see.

How to Fix It

• Re-integrate your ecommerce store with Omnisend if you notice missing data, following the platform’s official step-by-step integration guide.
• Check your sync settings monthly to ensure new products, customer profiles, and order data are pulling in correctly.
• Use Omnisend’s product catalog feature to auto-populate emails with up-to-date pricing, images, and stock levels.
