In email marketing, everybody speaks about layouts, designs, campaigns, messages, code, and templates. An important difference is that Email Templates, which are reusable layouts, and Email Campaigns, which are your individual email messages.
Email Marketing makes it possible to reuse campaign designs (user will be able to make the duplicate templates) or replicate existing campaigns but you should put reusable content in templates and message-specific content in campaigns.
You can also create your own template to match your brand. You can even insert regularly used images, videos, logos, or recurring content into your template, and reuse it for future campaigns.
A campaign is the email message you design and send to your specific contacts or bunch of smartlist.
After you select a template, you'll design your campaign on top of the template layout. In Email Builder, you can duplicate, delete, and rearrange different types of element blocks quickly.
