Sales is all about follow-up.
Not only sales but marketing is also the process of follow-up.
They are just in different forms.
Sales is a one-to-one follow-up.
Marketing is one-to-many follow-up.
You will need both forms to build up the trust with clients.
More importantly, whether sales or marketing follow-up, you all need to do it more than once…
Probably much more than once.
