Site, then Email, then Shell sets the letterhead your AUTOMATIC emails go out on - receipts, confirmations, the ones nobody presses send on. Your campaign emails are different: you write those, and each one used to carry its own logo and its own footer, built into that email. Change the logo and you changed it in every email, one at a time. A letterhead here is drawn once and named by as many campaign emails as you like, so changing it changes all of them.
Open Campaigns Manager, then Email Shells.
Press New Letterhead. The list starts empty, and stays empty until you draw one.
There are no ready-made letterheads. Every one on this screen is one somebody here drew, which is why a brand-new ministry opens an empty list rather than inheriting designs it never asked for.
It opens as a blank page. Drag a masthead and a foot onto it from the palette.
The palette on the right has ready-made rows - a logo masthead, a sign-off, a social row, a footer carrying your address - so a blank page does not mean building email tables by hand. Drop one in and change it. If your account has the newsletter archive, the palette also carries the real headers and footers from your Mailchimp newsletters, which are worth starting from because they are known to arrive looking right in real inboxes.
Once you have one, copy it from its row to make the next.
The copy button on a row starts a new letterhead from that one, which is how you get a second that differs only in its colours without drawing it again.
It opens in the Email Designer. Change the top and bottom however you like.
The middle section is not part of the letterhead. It is there to show you where the email will go, and it is dropped when you save - so anything you type in it is a sample for your own eyes. A letterhead has no subject line and no variables, which is why that row is shorter here than when you edit an email.
Give it a name you will recognise in a list, and Save.
"Newsletter", "Prayer letter", "Plain" - the name is what you pick from when you are writing an email, so name it after the kind of email rather than the month.
Starting a new email, pick the letterhead in the box that opens with it.
The pop-up that offers you a starter now offers your letterheads too, at the top. Pick one, then press Use on the starter you want, and both are taken at once. An email built from a product or an event is already written from that item, so there it offers the letterheads alone.
Tick "use this by default" and that campaign remembers it.
Next time you start an email in the same campaign, your usual letterhead and your usual starter are already in place - if you are happy, close the pop-up and carry on. Each campaign remembers its own, so a newsletter and a prayer letter keep different ones, and nothing is remembered until you tick the box.
Or change it later in the Letterhead box at the top of any email.
It appears round your words on the page as soon as you pick it, above and below the part you can edit, marked "not editable here" - that is the real thing that will be sent, not a preview of it. The email then holds only your words. Leave it on "No letterhead" and the email is sent exactly as you drew it, which is how every campaign email worked before this screen existed.
Double-click a row to change a letterhead later, or use the bin to delete one.
Changing one reaches every email that names it. The two right-hand columns say whether that letterhead draws a masthead and a foot - a dash in both means it draws nothing at all, which is almost always half-finished work rather than a choice.
Nothing is wrapped in a letterhead until somebody chooses one on the email. Every email you have already written and everything already sent is untouched, and stays that way until you open one and pick.
Choosing a letterhead REPLACES that email's own header and footer - they are left out when it sends, so you do not get two logos, and they disappear from the page while you are editing. Nothing is deleted: clear the box and they come straight back.
A change to a letterhead reaches every email that names it, including ones you wrote weeks ago and have not sent yet. That is the point of it - but it means a quick fix to one letterhead is not a small change. Send yourself a test from one of the emails afterwards.
Deleting a letterhead does not stop the emails that named it. They go out with no letterhead at all until somebody picks another one, so if you are replacing one, pick the new one on each email before you delete the old. You are not left to notice on your own: an email whose letterhead is not there says so under the Letterhead box, with a link to the screen that makes one, and the box that asks you to confirm a send says it too - which is the last moment you can change the answer.
The postal address and the Unsubscribe link are added when the email is sent, exactly as they always were - they are not part of a letterhead, and you cannot lose them by drawing one. If your letterhead already shows an address, no second one is added.
