How To Get Started with Back in Stock
Video Transcription: Welcome to Back in Stock! We will now take you through the install process along with offers and further information to help you get started. Back in Stock will start by asking for permissions – it will then go through the setup routine and check your store’s theme. If we have a premade integration for your theme, it will automatically apply it. This will add a Back in Stock button onto your product page. If we do not have an integration available for your theme, you will want to use the floating button integration. This will add our widget onto the side of the product page. If you want a theme integration for your theme, just get in contact with us on firstname.lastname@example.org, and we would be happy to get one setup for you.
We will now create your first notification. Back in Stock will navigate you to an active stock product. You can take a look at the new button widget and then sign up for a notification once the product is restocked. Shopify emails will be sent out to your customers automatically. The notifications can be limited, so only so many SM per level of stock. For example, if you restock five of our product and have the notification rate set to 2, it will send out 10 vacations each day or hour depending on setting. You can also set a minimum inventory quantity before any notifications will send out. On the dashboard, you can see a quick overview of incoming and outgoing notifications. There is also a Most Wanted area – this will filter products with the most recent and sent notifications. More options can be found in the dashboard from email reports to app integrations. If you have any issues or questions just let us know!
Analytics Dashboard and Reports – The analytics dashboard is the most powerful and advanced tool for store owners. With it, they can monitor conversion rates as well as notifications sent to their users in order to better understand how customers are interacting with them or keep track of which products have gone out of stock at any given time.
Quantity Required Field – When a customer is in the process of signing up for notifications about an out-of-stock product, they will have to enter their desired quantity. If it is not greater than zero, then we’ll show them an error message with instructions on how to fill that field; otherwise, both the quantity and its accompanying label can be edited right from within Settings.
Customizable Email Template – Many customization options are available to store owners in the email notification settings. Customizing subject lines, headings, text colors, and body is just a few clicks away with an easy-to-use template panel. Images for products can be modified as well by uploading from your computer or selecting one of our premade templates that will fit any business needs.
Email Delivery Settings – Back in Stock provides flexibility by letting you decide how often to notify your customers and whether they are for available products or preorder items. You can restrict the number of notifications going out, set a minimum inventory level before sending them, and disable all email notifications temporarily.
Customizable Signup Form & Button – The ‘Notify me when available’ button and signup forms are customizable so they match your Shopify theme. When you click the Notify Me When Available’ button, a form pops up for users to enter their email address in order to receive notifications about when products are in stock again on your site.
Instant and Scalable Email Delivery – If your store goes through inventory and restocks very quickly, this will be the ideal feature for you. Back in Stock’s rapid email delivery can help your store obtain an extremely high conversion rate. And if you have a large influx of customers day-to-day, rest assured that Back in Stock is equipped with the capacity to handle volume. In fact, we typically send out half-a-million emails each month! So whether your store has constant demand or fluctuating periods between major sales events (which most online retailers do), there isn’t any need worry about the software being overworked by all its responsibilities.
Instant Setup – As soon as you install the app, a ‘Notify Me When Available’ button will show up on product pages. Back in Stock integrates with more than 50 of the most popular Shopify themes, but if the app does not support a theme you’re using, we are happy to create custom integrations. Just reach out to us.
Experienced Support – The team at Back in Stock will work tirelessly to make sure that every small detail is taken care of. You can email our support team at any time, and we’ll get back to you ASAP.
Mailing List Integrations – Our mailing list integrations allow you to collect new email subscriptions when customers click the ‘Email me when available’ button on out of stock products. This way, you know right away what kind of products your target customers are interested in and can follow up with them with personalized campaigns in the future.
Shoelace Retargeting Integration – If you’re looking to boost your conversion rates even more, you can connect your Back in Stock and Shoelace accounts to create retargeting campaigns and re-engage the right customers.
