Yes, you can use HTML in your autoresponder and follow up messages. We provide 600+ HTML templates, as well as a drag and drop email builder that you can use to edit your HTML message content.
However, do recognize that some email programs do not support HTML. For that reason, you should always include a plain text version of your message, even when you are also sending an HTML version. By default HTML messages you create with our drag and drop email builder will have a plain text version of the message automatically generated.
When you send a message that includes both a plain text version and an HTML one, each subscriber will see the version that their email program supports (if it supports HTML, they'll see that version; if not, they'll see the text version).
AWeber offers hundreds of templates you’re welcome to use! If you would ever find yourself wanting to modify an existing template or would like a custom template built for you to reflect your branding, our Template Team would be happy to modify existing templates or design a custom template for you!
