Use one message on the page, in the email, and in the announcement

An offer that is rewritten for every channel becomes three offers. The page says one thing, the email says a friendlier thing, and the short announcement in a window says a third. A person who sees two of them has to guess which one is current.

Three places

Pick the sentence from Write an offer a stranger can repeat and put that sentence in three places:

• the first screen of the page
• the first lines of the email to people who came last season
• the card or the short announcement that points back to the page

The page can add the schedule under the sentence. The email can add the date and a link to the form. The announcement can be only the sentence and the link. The offer does not get a new slogan in any of the three.

What may change

The format changes. An email has a subject line, and the subject line can be the sentence itself, cut to the length the mail program will show. The announcement has less room, so it keeps the sentence and drops the second line about beginners, provided the page one tap away still has that line. A detail can move to the place that has room for it. The claim cannot fork.

What stays put

Who it is for, what they can do, and the single next action stay the same words. If Thursday at 6 fills up, all three places say full, or the announcement comes down. A page that says “book Thursday” while the email still says “spaces left” is two campaigns.

This is a method for the message. It does not rank channels, and it does not ask the page to carry a different promise from the letter.

Seal one sentence in three places

Take the sentence that already survived the stairwell in Write an offer a stranger can repeat. Put those words in three places on the same day.

The first screen of the page carries the sentence, then the schedule. The email to people who came last season carries the sentence in the opening lines, then the date and the link to the form. The card carries the sentence and the link, and it drops the line about beginners only because the page one tap away still has that line.

Read the three out loud, one after another. If you hear a friendlier verb in the email, or a shorter promise on the card, you have three offers. Put the original sentence back before any of them is sent.

What a subject line is allowed to cut

The mail program will hide the end of a long subject. Cut the sentence at a word the program will still show. Do not invent a warmer subject that no longer says who it is for. A subject that says “We saved you a spot” while the sentence says “book if you have attended before” is a fork. The person who reads only the subject has been told a different offer.

The announcement has less room than the email. It keeps the sentence and may drop the second line. It may not replace the sentence with a pun. A detail moves to the place that has room. The claim does not.

When the fact changes, all three move

If Thursday at 6 fills, the page, the email, and the card either say full or the card comes down. Leaving the card up because it was already posted is how a person arrives from the card and meets a full row the card did not mention. Take the card down, or change it in the same hour as the page.

A later campaign does not get a new slogan “for the channel.” It gets this sentence again, or it gets a new sentence that has passed the stairwell on its own. Two sentences in circulation are two offers, even when both are true about different sessions. Name the session in the sentence so the truths do not collide.

A check before anything is sent

• The page, the email, and the card contain the same sentence, not a paraphrase.
• The subject line is that sentence, cut on a word, or it is omitted.
• The beginner line is on the page even if the card dropped it.
• A full session is full in every place that still mentions it.

This check is the method. It does not say which place is more important. It says a person who sees two of them should not have to guess which one is current.

The page is the source of the sentence

The page holds the full sentence, including the beginner line. The email and the card are copies with less room, not co-authors. When you are unsure which wording is current, you open the page. You do not open the last email that went out, and you do not open the card that is still pinned. Those can be stale on purpose while you are mid-edit, and they must not stay stale after the edit is done.

Put the sentence in the HTML as text, not as an image of text. A card can be an image because a card’s room is small and its tools are crude. The page should not be an image. If the sentence is burned into a picture, a full Thursday cannot be updated by editing a line. It waits on a new export. That wait is how the three rooms drift.

Keep the source sentence above the schedule, in the same words a person on the stairwell heard. The schedule remains the proof under it. The email may link to the page. It does not get to summarize the schedule in a friendlier way that hides a full row.

What the email may add, and only that

The email may add a date stamp and a single practical line the page already shows: what to bring, or where the door is. It may not add a new claim. “Doors open 15 minutes early” is allowed if the page says it. “Your spot is reserved” is not allowed if the page says the person still has to book. The subject line is the sentence cut at a word, or it is omitted. A subject that teases and a body that clarifies is two offers in one envelope. The person who reads subjects in a list never sees the clarification.

If the mail program will clip the subject, cut at a word that still contains the refusal or the action. “Returning visitors can book Thursday at 6” can lose the beginner half only if the body still has it and the subject does not invent a different group. Cutting to “Thursday at 6” is tighter and still true. Cutting to “We saved you a spot” is a different offer. Do not cut your way into a lie that happens to be shorter.

The card comes down on the same hour

A card that cannot be edited in place has to be removable. If Thursday fills at noon and the card cannot change until tomorrow, take it down at noon. Absence is more honest than a card that still invites the booking. The page and the email change in that same hour, even if the card’s tool is slow. “We will fix the card in the morning” is how a person books from the card overnight and meets a full row.

Write the hour down when you do it. The note is the method: page, email, and card, and the time each one moved. A campaign report that says the card “performed” without saying whether the session was still open is not a check. It is a number with no sentence attached. This publication does not print that number on the page.

A second sentence has to earn the stairwell

A later week is not an excuse to keep a second slogan alive “for people who already know us.” If the offer is still Thursday at 6 for returning visitors, the sentence is the same sentence. If the offer is a different session, that session gets its own sentence, read aloud, with its own proof. The old card comes down so the two sentences are not both in circulation. Two true sentences about two different sessions still collide when a person sees both and cannot tell which session is which. Name the session in the sentence. “Thursday at 6” is doing that work. “Join us” is not.

Before anything is sent, read the page sentence and the email body side by side, then the card. They match, or the card is gone, or you are not done. The beginner line is on the page even when the card dropped it. A full session is full everywhere it is still mentioned. This is the method. It does not rank the three rooms. It stops a person from having to guess which room is current.

Copy from the file, then stop

Whoever prepares the email opens the page and copies the sentence from the HTML, then stops editing it. A tweak “so it sounds like email” is a new sentence. If the HTML sentence is too long for the subject, cut at a word. Do not rewrite. The card is produced the same way, the same hour, from the same line. A shared slide that is “close enough” is how the three rooms fork. Close enough is a second offer.

After the send, the HTML is still the source. If a typo is fixed on the page an hour later, the email that already went is a record of the old line, and the card still up has to match the new line or come down. You do not get to have three current lines. You get one current line and, at most, one sent record that is already in the past.
