Announcements are mailed the day of the wedding or the day after the wedding. Announcements are sent to those NOT invited to the wedding . . . but who will be interested in knowing it has occurred.
Example? Dear Great Aunt Sally lives in a nursing home on the other side of the country. Her health does not permit her to travel. Send her an announcement after the ceremony.
And yes, you send announcements out to people you know but cannot afford to have attend. Just make sure announcements are mailed AFTER the ceremony. That way, no gift-giving obligation is implied.
Invitations are mailed before the wedding and sent only to those you wish to attend.
Are you perhaps thinking of save-the-dates? Save-the-dates are not necessary, unless long-distance travel is involved for many or all of your guests.
Example? Destination wedding in the Bahamas. Your guests need advance notice so they can save up for their airline tickets.
If you are having the wedding in your hometown and most (if not all) of your guests are local, then there is no need for save-the dates.
Wordings for all three . . . invitations, announcements, and save-the-dates . . . can be found at verseit.com.
