In general, there are two types of party invitations, formal and informal invitations.
A formal invitation is normally in a set format with little to no room for creative drafting (please refer to “Invitation” under “General business” section), the following information relates to the drafting of a causal invitation. Although you can be as creative as you like in a casual invitation, please ensure you have the following:
The first thing to include in an invitation is the name of the party hosting the event or in whose name is the event being held under. If the invitee is not familiar with the host is or does not even know who the guest of honour is, he or she may not respond to the invitation.
The host can be the same as the guest of honour – e.g. Ryan’s Housewarming party, or they can be different people – e.g. Ryan’s girlfriend Meg is holding a surprise party for Ryan’s 30th birthday. In most cases, the invitees to the party are likely to be friends and relatives of the guest of honour, so there is no need to introduce him / her in the invitation. However, where the host is not the same person as the guest of honour, you may want to introduce the host as well as the relationship between the host and the guest of honour (see the example above).
Next is to decide who to invite. You should identify who you are inviting, and whether the invited guests could bring their spouses, children and other members of their family. You may want to invite your guest “on an exclusive basis” and remind them not to bring other guests. Make sure your venue has enough capacity to cater for all the invitees in case everybody accepts your invitation. Please also ensure that you include a phrase the “invite” the people. It may look impolite and insincere to send invitations to people with the venue, time and date but without the actually inviting them to attend. Depending on the situation, an invitation letter should be sent 2 to 8 weeks in advance to allow your guests sufficient time to save the date and mark their calendar.
Explain the purpose of the invitation. You should tell your guests what you are celebrating, so that they know what to expect and if necessary bring an appropriate gift. For example, a birthday present will be different from a housewarming present. Don't be afraid to mention details, such as the age of the birthday person, especially if it is a milestone birthday.
By including all the facts about your party, guests will have an easier time deciding whether they can accept the invitation and reach the event at the right place at the right time. Include the date of the party as well as the day of the week and be very specific on the time. Don’t just say Sunday afternoon as your guests do not know when to arrive – your invitation needs to tell your guests when to arrive, and if there is a specific end time, indicate that time on the invitation. You don’t want to have one guest arriving at 1.30 and the other arriving at 5.30.
Remember to tell your guests where the event will be held. Regardless of whether the party is held - in someone ’s home, or in a restaurant, club, or elsewhere, you need to provide the full name and address of the venue. Never assume that guests know where the host's home is, or where a restaurant is. If your guests are unfamiliar with the meeting place, include instructions or Google Maps location on the invitations. Providing clear and detailed instructions on how to get to the venue may seem obvious, but the wording in the party invitation is crucial to the presence of the guests.
The wording of your invitation letter should include the dress code for the type of event that you are organising. For a formal event held at an upscale restaurant or hotel, it could be black tie. For a cocktail, it could be business casual. If the party is a masquerade, the guests need to be prepared to come on with a theme. For a pool party, guests should bring swimming costumes and towels. Thus it is important to give advance notice to guests on what to wear or what to bring to the event.
You can show whether you will be providing food in drinks by indicating the type of party in the invitation – for example, a dinner party or a cocktail party. Otherwise, you can inform your guests on whether food, snack, canapes, drinks, or other refreshments will be provided so that the guests will know when they come to be hungry or full. This is also important if your guests want to bring something to the party. You can ask your guests if they have any food allergies or any special dietary requirements.
You may want your guests to respond to your event and let you know if they will attend. Give them a date you need to reply by. Also include an invitation message and tell them how to respond. It could be a phone number, email address, or response card. Knowing who and how many guests can come to the party is a great help to the host's preparation. It helps to estimate the amount of food and drinks, as well as details of seating arrangements, gift bags required for the occasion.
On the child's birthday, you can tell parents if they need to leave or stay. You may want to ask other parents to stay by getting them to RSVP. If you want to send the parents away, you can simply state in your invitation, "Please pick up your child at 6pm."
