There are numerous ways you can save a template to be used again for future email campaigns. It is good practice to do so as it will save you time on having to duplicate content. Using attributes inside email template content, you can store templates and reuse them as the data saved against the attributes is not static.
Emails templates are not to be confused with Section Layout Templates. These are pre-provided email layouts in the web interface which allows you to populate an email layout rather than building the layout from scratch.
Once you have finished building the email body in the design editor you can use the Save as Content Email Template option using the expandable side menu next to the Done Designing button. You’ll be prompted to provide a name for the template, then you can save.
Once templates are saved, you can select them at the beginning of all new email creations selecting the Choose a Template option.
If templates are not used for 6 months, content will expire and they will no longer be available for editing or sending.
