Your first sentence should make the right person think:
“This may be for me.”
Instead of:
“Welcome to my amazing community!”
Try:
“Are you a new community owner struggling to get members to participate?”
Or:
“If creating dinner every night feels exhausting, this community gives you a simpler plan.”
Lead with the person or the problem—not only the name of your community.
What problem could you mention in the first sentence of your next ad?
