Keep the rhythm
The traditional sales approach is to call each person on the phone book, promote your service, convince them that yours is good for them, and close the deal.
A better way is to ask for an email, build a list, and then promote it from your own desk.
Here's another one: you can make ads, run them on any social platform, and wait for people to come.
But no matter what methods are being used, the campaign must have a rhythm. The rhythm shows your job, your role, and your duty. It doesn't seek likes or applause but presents an act of your service. The rhythm shows your commitment to the people you serve.
Customers want to know if you'll still be around when they're ready to buy, to upgrade, and to change. Keep the rhythm.
