Quick answer
Share a wishlist as help, not a demand. Send the link with a short warm message and explain that guests can use it if they want a clear idea.
Good wording
"If you would like to choose something useful, I collected a few ideas here." This sounds lighter than "please buy only from this list".
Timing
For a birthday, send it 1-3 weeks before the event. For a wedding, share it with the invitation or when guests ask about gifts.
Reminders
One reminder is enough if the chat is busy or the event is close. Keep it practical: time, address, and wishlist link in one message.
What not to say
Avoid pressure, deadlines that sound harsh, and phrases that forbid other gifts. The wishlist should reduce stress, not create it.
Preparing a birthday?
Collect wishes in one link so guests can see available gifts and avoid duplicates.
