While you’re working on your email campaign, plan to send a few test emails to make sure your design looks fabulous in a variety of email clients. Send test emails to yourself and your team members.


Testing options

Testing is not a step to be missed in the campaign sending process. There are four tools you can use for testing inside WordFly.


Send Test Emails Send a few test emails before you deploy your campaign
Inbox Preview See your design in multiple email clients and scan for potential spam content
Subscriber Preview Preview personalization in your email and subject line with data pulled from your list
Email Checklist Review required elements, links, and images in your email. Download an image of your email to share.


What to expect when testing emails

  • Your test email is a full featured copy of your email.
  • List data field personalization is not included in test emails because the list is not using the same data as the list assigned to your campaign. Learn more about testing personalization.
  • Subscriber data field personalization can be included in test emails if the email address you are testing has those subscriber data fields saved on their WordFly subscriber profile. For example, if First Name has been imported for the email address being tested then First Name will appear in the test email.
  • All test addresses are saved in a list: Default Test List. You can access this list by looking up any addresses on the test list using Subscriber > Subscriber Search.


Send test emails

Send test emails to verify that everything is working properly in your email and that the design is rendering well. All WordFly user addresses automatically appear in the list. Send to a group or team by using an alias email set up by your organization. Add the alias email to the test list.


1. In your email campaign, click the Testing tab


2. Click Send Test Emails


3. Select the recipients

  • To add a new address, enter it in the input box, then click Add. You can only add one address at a time. 
  • Select the email formats you’d like to send. You will receive one test email for each version you select.
  • Select if you’d like to add the word TEST or a time stamp to the end of your subject line.


4. Click Send Test

Note: The button will be gray when no addresses are selected.


Testing tips

Are test emails not arriving in your inbox?

Make sure you have enough email clients represented in your test list.
For example, you might want to set up a general address with all the major ISPs (Gmail, Hotmail, Yahoo). Send your test emails to these accounts and check out how your email renders in those email browsers. Or use WordFly’s Inbox Preview to test your email across multiple email clients. 


Is any part of your email rendering oddly?
Pay attention to your email client stats to know where you should be focusing your attention. Check out Subscribers > Insights for an overview of email clients. The majority of rendering issues come up in Outlook on PC but typically most of your subscribers will be using a web-based email client or opening on a mobile device. If you are running into an Outlook issue, check out our article about Outlook rendering.


Click on your linked images and test links.
Are the links redirecting to the correct landing pages? It’s important to test every link in the email. It’s usually the one link that isn’t tested that ends up breaking when the email sends. Also be sure to check out the Email Checklist page for any issues.
