Do I have to send save the date to everyone?

Save the dates are not a formal requirement, and you are free to send them to a smaller group. Many couples send them only to guests who live abroad, who need to book flights, or who have busy schedules. They might also send them to close family and the bridal party, who need to plan ahead for hen dos and stag dos. For local guests, a standard invitation is usually enough. If you send save the dates to some people and not others, be careful. Guests who do not receive one may hear about the date from someone who did, and that can feel awkward. To avoid confusion, you can simply not send save the dates at all, and instead rely on your invitations. Or you can send them to everyone, even if some guests do not strictly need them. Another option is to share the date informally with the people who need it, by phone, email or a quick word, and then send formal invitations to all guests later. That way, no one feels left out. The most important thing is that every guest receives a proper invitation in good time. Save the dates are a bonus, not a promise to everyone. Use them in the way that works for your wedding and your guest list.
