This article discusses how to implement Follow-Up Emails. To learn more about the Follow-Up Email feature, click here.
To successfully implement your Follow-Up Email solution, ensure you've read through and met the following requirements:
Once you've read through and met the previous requirements, you can begin setting up your Follow-Up Email.
You have two options for sending your Follow-Up Email via an Email Service Provider (ESP):
1. Using Your Own ESP
2. Using PowerReviews as Your ESP
If you're using your own ESP to send your Follow-Up Emails, you will need to include a Write-a-Review link for customers to leave their review. The Write-a-Review link in your email must include these two variables:
1. pr_source=email
2. pr_merchant_user_email=<user email> (if you are encrypting email addresses, you must use pr_emuid instead)
For example, a Write-a-Review link may look like this for a given product (note that both variables are included in the string):
Reviews collected in this manner with the included variables will receive the 'Verified Buyer' badge in your Review Display.
If you're using your own ESP to send your Follow-Up Emails, PowerReviews recommends encrypting your customers' email addresses to ensure their privacy when they submit reviews.
By forcing email address encryption, the URL of the Write-a-Review form won't accept clear-text email addresses, even if the customer's email address exists in the PowerReviews database. It's also important to note that you can't pass the pr_merchant_user_email parameter to generate your Write-a-Review form. Instead, this parameter is replaced with pr_emuid, and the value associated with this parameter is an encrypted version of your customer's email address. PowerReviews uses a 128-bit AES/CTR/NoPadding cipher, along with the AES algorithm.
Contact your Implementation Team or Account Team for the necessary information needed to encrypt the email address strings. Once received, use the following steps to complete the process:
1. Lowercase the email string
2. Encrypt the email using an AES cipher, with the unique 16-digit string provided by PowerReviews as the encryption key and 'EmailPWRIVSpecIV' as the IV
3. Convert any '+' characters to '==PLUS==' in the encrypted email string in Step 2
4. URL-encode the string from Step 3 using UTF-8 encoding
5. Assign the resulting string to the pr_emuid parameter within the Write-a-Review wrapper page URL
Once you've read through and met the previous requirements, navigate to the PowerReviews Portal to get started.
1. Click + Setup in the left navigation menu
2. Click Email Manager on the Products page
3. You will be directed to the Content tab, where you can begin filling out the required information (this can be edited at any time in the future):
4. Click Save Content
5. You can send yourself an email preview by entering your email address and clicking Send Test Email (explained more below)
PowerReviews uses a process called IP warming, which gradually increases the number of emails sent, so that IP reputation is sustainably built over time. One factor that can impact ongoing IP reputation and prevent emails from being reliably delivered is sending drastically different volumes of emails on a day-to-day basis. To minimize these fluctuations and ensure a higher level of IP reputation, we automatically adjust the number of emails sent by a client per day, based on the expected volume.
More information about IP warming and how we scale our email sends can be found here.
For items purchased by the same customer on the same day, we will send up to 10 items in a single email. More than that, and it will be broken out into additional emails of up to 10 items.
When you click Send Test Email, you'll receive both an HTML version of the email and a plain-text version of the email. It's important to note that only one of these email versions is sent to your customers.
The HTML email is sent to your customers by default, unless their email preference is to receive text-only emails. In that case, those customers would receive the plain-text version.
The test email you receive will reference your Product Data and will pull in items from your catalog as 'dummy' data.
Once you've read through and met the previous requirements and completed the email configuration setup under the Content tab, you can move on to the Settings tab to schedule and activate your emails.
Determine how many days after purchase you want to send your emails to your customers, and adjust the toggle arrows accordingly. If you use the Checkout Beacon for your Order Data, PowerReviews will use the date that is triggered at the point of purchase, not the shipping date. If you use an Order Feed for your Order Data, PowerReviews will use the date that is passed in the order_date column. Consider this as you are determining the number of days post-purchase you want to use for the first email send.
You may want to configure your Follow-Up Emails in a particular format, depending on your average customer's cart size and your desired user experience with the email itself. You can choose between two different email templates and two different review collection methods, which are explained below. All customization options can be selected on the Settings tab under Follow-Up Features.
