The follow-up that happens whether or not you remember.
Most lost deals are not lost to a better product. They are lost to a third message nobody ever sent.
Nothing sends until a person approves it

A sequence that watches for enquiries going quiet, writes the next message from that customer's own history, and holds it in a queue until somebody approves it.
Where the deal actually goes
Monday, they ask what it costs. You answer the same day, which is the part everybody gets right.
Then they say they will think about it, and the conversation stops. Tuesday is busy, Wednesday is busier, and by the following week the thread has scrolled up past four newer ones. Nobody decided to stop chasing. It just stopped happening.
Three weeks later they buy from whoever sent the third message.
The sequence, and the actual words
Four touches over two weeks. Copy them and run them by hand if you like, they work either way.
Answer the question they asked
The bit most people get right. Answer properly, and add one thing they did not ask for.
Nudge, without asking if they got it
Never send just following up. Add something. A slot, a detail, a reason to reply.
Change the question
If they have not answered twice, the question is wrong. Ask something easier to say yes or no to.
Close the loop cleanly
Give them a way out. It gets you an answer, and it keeps the door open for later.
Who runs this
Every industry we work with runs some version of this. It is the most universal sequence there is.
Where this stops working
A follow-up sequence cannot fix a weak offer. If the price is wrong or the product is not right, four well-timed messages just get you a faster no. This works when the deal was real and the attention ran out, which is most of the time, but not all of it.
Questions people ask
Will the AI send these on its own?
No. It drafts and stops. Every message waits in a queue until a person approves it.
How does it know somebody has gone quiet?
No inbound reply within the window you set. Twenty-four hours, three days, a week, whatever fits how you sell.
Can I change the messages?
All of them. These are a starting shape, and the ones above are yours to copy whether or not you buy anything.
What if somebody replies mid-sequence?
It stops immediately and hands the conversation to a person. Nobody gets a day-seven nudge after they have already answered.

Twenty minutes on your real list. Most people find something from last week they had genuinely forgotten about.
