The first message.
A WELCOME MESSAGE
"A new customer has bought [what]. Write a welcome message covering: what happens next, how to reach us, our hours, and what is included."
CONFIRMING AN ARRANGEMENT
"Here is what was agreed: [details]. Write a confirmation restating the arrangement, the price, the dates and what each party will do."
Send this every time. Most disputes involve something nobody wrote down.
SETTING EXPECTATIONS
"Write a short note for new customers explaining our support hours, expected response time, and what counts as urgent."
REQUESTING WHAT YOU NEED FROM THEM
"I need [list] from a new customer before I can start. Write a message requesting each item, explaining briefly why each is needed."
Most projects stall waiting for something the client did not know was needed.
A FOLLOW-UP AFTER TWO WEEKS
"A customer started with us two weeks ago. Write a short check-in asking whether everything is working and whether they need anything."
