Regarding bridal shower invitations, the timeline for mailing them is crucial. Typically, invitations should be sent out 6-8 weeks prior to the event to allow guests ample time to RSVP and make arrangements. The content of the invitations should include essential details such as the date, time, and location, as well as a clear RSVP deadline and contact information. To ensure that RSVPs are tracked efficiently, consider using a website or an RSVP management tool.
