The content of your Send Test emails should look the same, but a few things will be different:
Merge fields will not pull actual data (Example: Hi [Contact First Name]). This includes the Company Information in the footer.
Subject lines will have "Email Test" before it.
All Dynamic Content will display in email test sends.
Footer address will not pull actual data.
The email will be sent from a "donotreply" address and may land in your SPAM folder.
Use the Send Test button while working on your template to see how your design and formatting looks, not to see the final product.
Add yourself as a contact in your database, then send the email to yourself as if you are a recipient of this email.
💡 Tip: If you send a Basic email to yourself only, the company information block in the footer will not populate. You need to send to two or more contacts to view the company information footer.
