so nobody ever receives “Hi ,”

any real contact, before you send
“Hi {FirstName}” stopped impressing anyone a decade ago.
Subject line, preview text, body, button label. Standard fields and every custom one you store — each with a fallback, so a contact with no company still reads like a sentence somebody wrote.

And when it's blank
Nobody ever receives “Hi ,” because a field was empty.
Any field, anywhere in the email
First name, company, job title, plan, renewal date — or any custom field you store. Put it in the subject line, the body, the button, anywhere text goes.
Subject line
{{FIRSTNAME}}, your {{PLAN}} plan
Every tag gets a fallback, so a contact with no company still reads naturally. This is the step most tools skip and most embarrassing sends come from.
Preview the email as any real contact on your list, compare two side by side, and send yourself the resolved version before you commit to the send.

See it as they will, before you send
Fields, fallbacks, conditional sections and AI variants — with the preview and the checks that stop any of it going wrong.
Subject line, preview text, body copy, button labels. Standard fields and every custom field you've added to a contact.
Set what shows when a field is empty, so a contact with no company still reads like a sentence somebody wrote.
Show or hide a whole section on a condition — plan, country, signup date, anything you store. One template, several emails.
The line that decides whether the email is opened at all gets the same fields and fallbacks as the body.
Ask for the same email rewritten for a different audience and get a version per segment, not just a different first name.
Pick anyone on your list and see exactly what they'll receive, with resolved values highlighted so the differences are obvious.
Put two contacts' versions next to each other to check the personalisation actually changes something worth changing.
A typo in a field name is flagged before you send, along with any tag that has no fallback set.
See what share of the list actually has each field populated, so you know when a fallback is doing most of the work.
Test sends arrive fully resolved for a chosen contact, rather than showing you raw tags in your own inbox.
Values are filled when the email goes out, so a contact who updated their company yesterday gets today's version.
Analytics shows what personalisation is worth on the same send, so you keep the fields that earn their place.
