Step 1: Connect Omnisend to Your WordPress Website
Once you’ve signed up for your Omnisend account, the first step is to connect it to your site. If you don’t have an e-commerce store, no worries — Omnisend supports WordPress and many other platforms.
Here’s how to connect Omnisend to WordPress:
- From your Omnisend dashboard, click the Connect Your Store button.
- Choose WordPress from the list of supported platforms. Omnisend also supports Shopify, Wix, WooCommerce, BigCommerce, and more.
- Follow the three-step connection process:
- Download and activate the Omnisend WordPress plugin.
- Copy your API key from Omnisend.
- Paste the API key into the plugin settings on your WordPress dashboard and verify the connection.
To install the plugin, go to your WordPress dashboard, hover over Plugins, and select Add Plugin. Search for Omnisend, then install and activate the plugin called Newsletters, Email Marketing, SMS, and Popups. If you’re using WooCommerce, there’s a dedicated plugin available as well.
After activation, return to Omnisend, copy your API key, and paste it into the plugin’s home screen in WordPress. Click Connect Omnisend, and then verify the connection back in your Omnisend account by clicking the Check API Connection button.
Once connected, your WordPress site will appear in your Omnisend store settings, and you’re ready to start collecting leads!
Step 2: Create a High-Converting Pop-Up Form
With your WordPress site connected, it’s time to design a pop-up form to capture visitor emails. Pop-ups are one of the most effective ways to turn website traffic into subscribers because they grab attention immediately and can be highly customized.
To create your pop-up form:
- In your Omnisend dashboard, click Forms from the left menu.
- Omnisend provides a pre-selected pop-up template that you can preview and launch right away. Alternatively, click View Other Form Types to browse a wide range of templates sorted by goals, themes, and form types.
- Choose a template that fits your brand and goals. For example, select a branded email capture pop-up designed to collect email addresses with a simple offer.
- Click Use Template to open the form builder and start customizing.
The form builder is intuitive and powerful:
- Left panel: Drag and drop elements like email fields, phone number fields, buttons, countdown timers, and even interactive elements like a Wheel of Fortune.
- Right panel: Customize behavior and theme settings, including when the pop-up appears, targeting rules, scheduling, frequency, and even A/B testing.
- Bottom tabs: Edit the form itself, success messages after submission, and subscribe states for returning visitors.
- Center preview: See your changes live and click directly on any element to edit text, images, buttons, or layout.
- Top-right toolbar: Toggle between desktop and mobile previews, undo/redo changes, save progress, and enable the form to publish it.
To customize your form quickly:
- Click on the placeholder image to replace it with one that matches your brand.
- Adjust the background and button colors using the color swatches in the layout settings to align with your brand guidelines.
- Edit text directly in the preview area, much like editing an email or document.
- Customize the button’s call-to-action text from the button text settings panel.
Don’t forget to configure form behavior settings such as audience tags, scheduling, device targeting, and frequency to maximize conversions. Also, make sure to update your success and subscribe notifications to maintain consistent branding across the entire form experience.
Before publishing, always preview your form on both desktop and mobile to ensure it looks great across devices.
Once you’re happy with your design and settings, simply click Enable Form to make it live on your WordPress site. Because you’ve connected your site via the API key, there’s no need for embedding or coding — Omnisend handles the integration seamlessly.
Step 3: Set Up an Automated Welcome Email Workflow
Capturing emails is just the beginning. To build trust and engagement, it’s crucial to follow up with new subscribers immediately. That’s where Omnisend’s email automation shines.
Here’s how to set up a welcome email that sends automatically when someone subscribes via your pop-up form:
- From the Omnisend sidebar menu, click Automation.
- You’ll see a default welcome email workflow ready to use. You can select this or explore other automation workflows offered by Omnisend.
- Hover over the workflow you want and click Customize Workflow to open the automation builder.
- In the automation builder, you’ll see a visual flow starting with a trigger (subscriber signup), followed by a delay (default 1 minute), and then the welcome email.
- Customize each step by clicking it and editing settings in the right panel — for example, adjust the trigger filters or edit the email content.
- To edit the email message, click Edit Content to open the full email builder and add your welcome text and links to lead magnets like a free ebook.
- When everything looks good, click Start Workflow to activate your automation.
This automated welcome email delivers immediate value, fulfills any promises made in your pop-up offer, and sets a positive tone for the relationship with your subscribers.
Step 4: Test Your Setup and Monitor Results
After setting up your pop-up form and welcome email automation, it’s essential to test everything to ensure it works smoothly.
Visit your website and wait for the pop-up to appear (in this example, it shows after 3 seconds). The form should look professional and not intrusive or spammy.
Fill out the form with a test email and submit. You should see a success message confirming your subscription.
Wait for the delay period you set (e.g., 1 minute), then check your email inbox. You should receive the automated welcome email with your lead magnet link.
Back in Omnisend, you can monitor form views, submission rates, and subscriber counts in the Forms Management and Audience & Contacts sections.
This setup creates a seamless lead generation and nurturing process that builds trust and engagement from day one.
