The task of asking members to renew their membership in your association during a pandemic can be a delicate and tricky thing. Everything is so uncertain right now.
You should let them know that you recognize the challenges they are facing and that even though money might be tough right now, you truly appreciate their continued support.
You will want to remind them that their commitment allows your association to continue focusing on its mission, communicating relevant industry specific content, providing valuable member only resources, and offering educational programs and events.
Often it's easier to keep your current members than recruit new ones, so be sensitive to their current situation.
