There are seemingly endless elements that go into planning a party, but sending out invitations is one of the most vital! Once you’ve picked out the perfect invitations and narrowed down your guest list, send the invitations out in plenty of time so your guests can start making plans to attend. Be sure to address and mail the envelopes correctly to make sure everyone gets their invitation. If you’re not keen on sending out a lot of paper invitations, consider alternatives, such as digital invitations. Method 1 of 5 1. Finalize your guest list at least 4-6 months before the party.
