"RuffRuff 予約販売" helps you reduce lost sales opportunities that occur when items are out of stock, before a new product launch, or while waiting for restock.
It lets you implement pre-order sales on your Shopify store surprisingly easily, letting you register an unlimited number of pre-order products and accept an unlimited number of pre-orders. It can also prevent customers from ordering pre-order and regular products in the same order, and can send restock notifications when the arrival date is undetermined.
It also has many unique features not found in other pre-order apps, such as "deferred payment," which lets you collect payment before the product ships.
For an ecommerce site, email marketing is an important marketing method for building customer relationships and growing sales.
The blog article below introduces the benefits of email marketing on Shopify and recommended email marketing apps. Feel free to use it as a reference.
This article explains in detail the features, functionality, pricing, and usage of "Omnisend," a popular email marketing app on Shopify sites.
What is Omnisend?

Omnisend is the second most well-known email marketing app after Klaviyo. It's relatively affordable to get started with compared to Klaviyo, and its settings screen, while in English, is intuitively easy to understand.
Features of Omnisend
Omnisend has 3 key features
- A rich feature set
- No coding required
- Free to get started
We'll explain each in detail
A rich feature set
Omnisend does more than just send email newsletters — it comes with a rich set of features, including a form builder for collecting email addresses, an automation feature to automatically send newsletters based on conditions, and analytics functionality to analyze the newsletters you've sent.
Intuitive to use with no coding required
If you've ever touched "Notifications" in the Shopify admin, you probably know that customizing the email body requires a certain amount of HTML and CSS knowledge. And many people have probably given up on customizing it as a result.
Omnisend has an editor feature that lets you easily create emails, so you can intuitively create freely customized HTML emails (rich emails).

Free to get started
With Omnisend, up to 500 emails/month are free, and up to 250 SMS messages/month are free. This means you can try out the app hands-on to see if it's genuinely useful, without spending any money.
Key features of Omnisend
Omnisend's basic features are the following 4
- Collecting email addresses
- Managing email addresses
- Sending newsletters
- Analyzing sent newsletters
We'll explain each in detail
Collecting email addresses
To send a newsletter, you need email addresses to send it to.
With Omnisend, you can easily create a newsletter signup form to collect email addresses and embed it on your Shopify store.
Managing email addresses
You can manage collected email addresses along with additional information, such as "how the address was collected," "whether they're subscribed to the newsletter," and "whether they've purchased a product," and you can also use that additional information to create segments.
Sending newsletters
As you'd expect from an email marketing app, Omnisend has two types of newsletter delivery features. The first is "Campaigns," a feature for manually sending emails. The second is "Automations," a feature for automatically sending emails based on certain conditions.
Using these two features together lets you run email marketing efficiently.
Analyzing sent newsletters
Omnisend has features to analyze whether a sent newsletter "actually reached the managed email addresses," "was opened," and "had links inside it clicked."
By using Omnisend, you can go beyond simply sending a newsletter, and instead run a measure-analyze-improve PDCA cycle for your email marketing efforts.
Omnisend pricing plans
As mentioned above, Omnisend can be used for free, but the price changes based on the number of email addresses on your list and the number of emails you send.
We've listed reference pricing below. For more precise figures, check the pricing simulator on Omnisend's official site.

Benefits of using Omnisend
Automatic integration (sync) with your Shopify data
The reason Shopify stores choose Omnisend over other email marketing apps is likely its automatic integration with Shopify data.
Because it integrates with your Shopify customer list and product data, you can skip the hassle of migrating email addresses from Shopify to Omnisend, or manually looking up products in Shopify and copy-pasting product information for your newsletter.
Track customer behavior data
Omnisend has a feature that automatically tracks customer behavior data. This feature is available even on the free plan, and lets you see how customers navigated your site before making a purchase.

Easily create HTML emails (rich emails)
As mentioned earlier, creating an HTML email (rich email) without an editor is quite difficult. Omnisend's editor lets you place the parts you want to use (images, buttons, etc.) via drag and drop and simply fine-tune the content, making it easy to create HTML emails. It also comes with a rich set of templates, so using a template that fits your purpose lets you create a newsletter in a short amount of time.
Automatic newsletter delivery
Step emails and scenario emails are important email delivery methods in email marketing.
It's best to avoid having a person manually time and send step emails or scenario emails, from the standpoint of workload and the risk of human error.
Omnisend has a feature that automatically sends newsletters based on conditions, so once you set it up, it will keep sending your step emails and scenario emails automatically from then on.
Drawbacks of using Omnisend
Costs money
You can use it for free, but if you need a certain number of emails on your list or emails sent, costs apply. Some large Shopify stores spend several hundred dollars or more.
Consider whether to use it by comparing the customer relationships and sales growth achieved through your newsletter against the cost of Omnisend.
The admin dashboard is in English
Omnisend's admin dashboard doesn't support Japanese. The English used in the admin dashboard isn't especially difficult, but it might be a bit of a hurdle for those who aren't comfortable with English.
Omnisend's admin dashboard doesn't support Japanese, but rest assured that you can still send Japanese-language newsletters with Omnisend.
Your account gets deleted if unused for over six months
Please note that with Omnisend, your account is automatically deleted if you haven't accessed it for more than six months. For example, even if you're only using Omnisend's automation feature and otherwise leaving it untouched, your account — along with any automations you've set up — will be deleted. (We've experienced this issue firsthand with a client we support, and re-setting everything up was a real hassle.)
If you're using Omnisend, be sure to log in regularly.
