  • Create the final seating chart based on confirmed guest counts.

3. Logistics and Vendors

  • Break it Down: Tackle one section of this list per week rather than trying to complete everything in one sitting.

Frequently Asked Questions

When should I send out my wedding invitations?

Invitations are typically mailed six to eight weeks before the wedding. If you are having a destination wedding, you may want to send them out earlier, around three months in advance.

What if I haven't received all my RSVPs by the deadline?

Once the deadline passes, reach out to the missing guests personally via phone or email. Give them a firm "final" date to respond so you can provide accurate numbers to your caterer.

When is the best time to apply for a marriage license?

Requirements vary by location, but most marriage licenses have an expiration date. Check your local clerk’s office website to see how long your license is valid to ensure you don't apply too early.
