To install the plugin, go to your WordPress dashboard. Now go to ‘Plugins’ and click ‘Add New.’

Add new plugin

In the Add Plugins section, search for the ‘SMS alert’ Plugin.

Select SMS Alert plugin

We have successfully installed the plugin.

To connect your website to the SMS alert account, we need to log in to our SMS alert plugin.

So to login to this plugin, go to ‘WooCommerce’ and click on ‘SMS Alert,’ and you will get this page.

Go to WooCommerce and select SMS Alert

Now here, you need to enter the login details of your SMS alert account.

Enter details for SMS Alert account

As soon as you create your SMS alert account, you’ll receive the login details to your email address while creating your SMS account.

Step 3: Enable SMS Notifications

Once you enable the SMS notifications, you can start sending SMS to your customers.

So, to enable it, go to Woocommerce and click on SMS Alert and then click on ‘Customer Notifications.’

Now select when you want to send the SMS to your customers from this list and click on ‘Save changes.’

Enable SMS notifications

So now we’ve successfully enabled the customer SMS notification, and your customers will receive notifications on their purchases.

Next, let’s see how you can verify your customer before placing an order. Suppose a customer is placing an order and processing the order. You want to ensure that the order is genuine.

So, How can you Verify your customer?

You can do that by sending an OTP to your customer’s mobile number during the time of purchase or placing the order.

OTP is a one-time password that is sent to the customer’s mobile number to verify their number on our website.

So the customer has to enter the OTP and verify their mobile number before placing the order.

Enabling the OTP Feature

To enable it, go back to your WordPress dashboard and then go to OTP Settings (in your Plugin).

Enable OTP feature

Now to add the OTP feature on your checkout page, enable the option “OTP for Checkout.”

OTP for checkout

And if you want to enable OTP verification, when your customer selects a particular payment method, enable the option “Enable OTP only for Selected Payment Options.”

Then click here and choose your payment method for which you want to enable OTP Verification.

Choose Cash on delivery for payment option

Here, by selecting ‘Cash on delivery,’ you ensure that the OTP will only be sent to people who opt for the COD option.

So, when the customer selects cash on delivery payment, they will get an OTP to their mobile number for verification.

Now instead of the ‘proceed to checkout button,’ if you want to show the OTP verify button on your checkout page as shown here,

Click here to verify your phone

Enable the option “Show Verify Button at Checkout.”

Show verify button at checkout

And if you want to show an OTP Verification in a Pop-up on the checkout page like this,

Just enable the option “Verify OTP in a Popup.”

Verify OTP in Popup

Once you’re done, click ‘Save changes,’ and the OTP feature will be enabled on your website.

If your customer adds the product to the cart and clicks on ‘proceed to checkout and selects ‘cash on delivery’ as the payment method, it will ask them to verify their number to place the order, as shown here.

Validate OTP in Popup

So once they enter the OTP and then click on ‘Validate OTP’, their mobile number will be verified.

So, once your customer verifies their phone number, they will be able to place the order on your site.

So this is how you can verify your customer before they place an order on your website.

Next, let’s go to the BONUS part of this tutorial, where we will see how you can notify your customer about the product which is back in stock.

Bonus: Enabling Back in Stock Messaging Feature

Now let’s say your customer is looking for a product on your website that is not available right now, and you want to notify your customer when it is back to stock.

How will you notify your customer about it?

You can do that easily by sending an SMS to your customer when the product is back in stock.

Back in stock SMS

To send ‘back in stock’ SMS, go back to your dashboard and click ‘Back in stock.’

back in Stock tab

Now select both of these options ‘send msg to the customer when product is back in stock’ and ‘send msg to customer when product is subscribed,’ and then click ‘save.’

Check the boxes and Save

Now the back-in-stock feature will be enabled on your website.

If a customer selects an ‘Out of stock’ product from your website, they can enter their phone number to get a message whenever the product is back on stock.

Enter mobile number for SMS

So, when this product is back in stock, your customer will get an SMS to their mobile number. So once the product is back in stock, your customer will receive an SMS like this,

SMS received

So this is how you can notify your customer when the product they’re required to look for is back in stock.

Next, let’s see how you can receive SMS notifications when a customer places an order on your site.

How to Receive Notifications when a Customer places an Order?

So to receive the SMS about the orders placed on your site, go to your website’s dashboard and click ‘admin notifications.’

Once you have chosen the options of your choice, click ‘Save.’

So this is how you can receive SMS notifications when a customer places an order.

Now, if we go to the SMS alert account, we can see a trial account.

Since it’s a free trial account, we will get only 5 SMS credits which mean we can send only 5 SMS from this account. So now, to send more SMS, we need to purchase the SMS credits.

So to buy more SMS credits, go to your dashboard and click ‘Buy SMS.’


To purchase the SMS (credits), the minimum credit value is 5000, which means you can send up to 5000 SMS to your customers.
