Thank you for reaching out in the Community! In order to send a simple text email, you will select the blank template from the template picker in Constant Contact. From there you will need to drag and drop a text block in to your email. I have included a couple articles that will walk you through the steps.
If you would still like to be contacted and connected to our support team via phone, please send us an email at socialsupport(at)constantcontact(dot)com with a reference to this post, your username and a good contact phone number.
