One of thr most important things you can do for your hustle right now and for the long term: stay in touch with your clients.
Don’t offer any services, don’t mention anything that sounds like you’re trying to sell them anything. Don’t mention retainers or fees. This isn’t quite the time for all of that and you know it. They definitely know it. But, the least you can do is check in on them. See how they’re coping and dealing with everything going on right now. Send a text, send an email, leave a voicemail. Be genuine. Ask how are they doing. Ask if they need anything you might be able to help with. And let that be the only thing you bring up in the conversation.
Make it a point to be there for you clients so they will always be there as your clients. It doesn’t take anything away from you. It doesn’t cost you anything but your time. And you’ll be thankful in the long run. And so will they.
