How to use these templates
Every template below is written the way a person types, not the way a marketing department writes. Square brackets mark the part you must replace with something specific from the conversation. If you cannot fill a bracket, do not send that message: the fact that you have nothing specific to say is the actual problem, not the wording.
The timings are counted from the trigger event, and they assume working hours. If the interval lands outside a reasonable window, push it to the next morning rather than sending late. Nothing in a sales sequence is urgent enough to justify a message at eleven at night.
