Email Contents

An Email Content is what gets sent: one or more templates, with the subject lines, from names and preheader text that go with them. Holding several of each in one Email Content is how you A/B test, since a subject line or from name not assigned to a template is picked at random each send.

Instructions

1. Navigate to Email Contents > Create Email Content. Enter a name and click Next to create the container.
2. Add templates: choose from Gallery (pre-built designs), Custom HTML (paste your own), Drag and Drop (visual builder), or Text (plain text). Multiple templates can be created per Email Content for A/B testing.
3. For Custom HTML: paste HTML, upload images (JPEG, GIF, PNG, BMP, WebP), mark tracking pixels, and preview. Links and images are parsed automatically.
4. Add Subject Lines (multiple for A/B testing — click Add with AI to generate five options from a prompt; regenerate until you like the results) and From Names. Each Subject Line and From Name can be assigned to a specific template; unassigned ones are randomly selected on each send. Add Suppression Lists to prevent certain addresses from receiving this content.
5. Set Preheader Text to control the preview line an inbox shows after the subject:
   • The Preheader Text box is in the top row of the template editor, next to the template name. It is on Custom HTML and Text templates. Leave it blank for no preheader.
   • Gallery and Drag and Drop templates do not have this box. Those use the editor's own body-level Preheader Text setting instead, which is stored inside the design. Setting it in two places would give one value two owners.
   • Right-click the box to insert replacement tags. Content feeds, the unsubscribe link tags and the Signup fields are not offered here, because none of them makes sense in a preview line.
   • Up to 255 characters, emoji included. Gmail shows roughly the first 100 and Apple Mail roughly the first 140, so put the useful words first.
   • On an HTML template the preheader is placed at the top of the HTML at send time, hidden from view, and padded with invisible spacer characters. Without the padding the inbox fills the rest of the preview with the first line of body copy. It is left out of the plain text part of the message.
   • On a Text template it is written as the first visible line of the body, because a plain text email has nowhere to hide it. Tell users this before they set one there.
6. Use Replacement Tags for personalization (right-click in editor): contact fields like {First Name}, sender domain info, content feeds, and SubIDs. Tags support default values with ## syntax.
7. Send a Test email: click Test > enter email address > choose a send integration > Send.
