Write your emails

In short

You write emails in the editor, as a reusable template or straight in a campaign. Both use the same editor, which checks the email as you type.

Write a template

Step 1: On Templates, click New template.
Step 2: Write the subject and the email. Add variables like {{first_name}} from the toolbar at the bottom.
Step 3: Add the compliance footer: the unsubscribe link and your postal address. Every email needs both.
Step 4: Work through Inbox readiness beside the email until it's mostly green.
Step 5: Click Preview (the eye) to see it filled in for a real contact.

The template editor: subject, body with variables, the toolbar below, and Inbox readiness, AI review and Test email on the right. — The editor. Inbox readiness and AI review sit beside the email; the toolbar is below it.

Everything saves as you type; Save (or Ctrl+S) saves at once. On Templates, each template's menu (the three dots) has Edit, Duplicate and Delete.

The editor

Visual (the brush): For writing: formatting, links, images, emoji, variables and the footer.
HTML code (<>): Shows the email's HTML, to edit it directly.
Designed emails: An email built in HTML, with its own layout, is shown as it looks and edited in the code view, so its layout is never flattened. Convert to simple text turns it into an ordinary email.
Desktop and Mobile: Show how the email reads on each, in the editor and in Preview.

Plain, short emails reach the inbox more often than designed ones. Save designed layouts for people who know you.

Variables

Variables are filled in for each contact when the email is sent.

{{first_name}}: Becomes: Any column of the campaign's list, by its name.

{{sender_name}}: Becomes: The sending mailbox's name. Also {{sender_first_name}} and {{sender_email}}.

{{unsubscribe_url}}: Becomes: A link to unsubscribe in one click. Required in every email.

{{physical_address}}: Becomes: Your business address from Settings. Required in every email.

{{RANDOM | Hi | Hello}}: Becomes: One of the options for each contact (spintax), so emails don't all read the same. Options can hold variables.

Variable	Becomes
`{{first_name}}`	Any column of the campaign's list, by its name.
`{{sender_name}}`	The sending mailbox's name. Also {{sender_first_name}} and {{sender_email}}.
`{{unsubscribe_url}}`	A link to unsubscribe in one click. Required in every email.
`{{physical_address}}`	Your business address from Settings. Required in every email.
`{{RANDOM \| Hi \| Hello}}`	One of the options for each contact (spintax), so emails don't all read the same. Options can hold variables.

A contact with no value for a variable an email uses is skipped, not sent a broken email. Set a name on every mailbox: without one, {{sender_first_name}} comes from the address and reads “Sales” for sales@.

Inbox readiness

Beside the email, Inbox readiness scores it as you write: spam-trigger words, subject length, links, images, length, formatting, tone, personalisation and variety. Each item says why it matters, and many have a one-click fix or Fix with AI.

These checks are advice; they never block sending. What blocks sending are the template rules: the unsubscribe link, the postal address, and variables the list can fill.

AI review

On a template, open AI review and click Review now. SendPath AI reads the saved email for a misleading subject, risky claims or anything that looks like phishing, and suggests changes you can apply. It only warns; it never passes or blocks an email.

Preview and test emails

Preview shows the email filled in for a real contact. A test email sends it to you from one of your mailboxes, filled in with the first contact on the list. A campaign needs a test of its current emails before it can start; change the emails afterwards and it asks for a new test.

If something's wrong

The template fails the check.: It's missing {{unsubscribe_url}} or {{physical_address}}, or a brace is missing in a variable. The check names which.
{{physical_address}} is empty in the preview.: Add your business address in Settings.
My designed email looks different in the visual view.: Designed emails are edited in the HTML code view. The visual view only shows them.
