Event Name
Ensure that your events are big and bold. If your event's got a tagline, make it smaller than your event names instead of the same size.
Host Name
State clearly who is the organiser of the event. If you have other event partners like associations, media partners and sponsors. Remember to include them as well.
Date, Time, Location
Ensure that you include the date, time and location (inclusive of the name of the room/hall and level).
RSVP Number
State the contact person and number to call to RSVP. If possible, allow more than one mode to RSVP, if possible. e.g. telephone, fax and email.
Significance of Event
If possible, it'll be good to let the attendee have more information about the event such as a short introduction of the event, event history, if any, benefits of attending, who should attend, testimonials from last event's attendees, if any, etc.
Dress Code
This is especially important if it is a dress up party or formal party. Nowadays, you also need to be careful about the term "business attire" because some companies have dress down policies that allows their employees to work in polo T-shirts and jeans. Therefore, business attire for them would be polo T-shirts and jeans. If it's shirt and pants that you mean, state that clearly. Alternatively, you can list attires which the attendees should not wear e.g. round neck T-shirt, sandals, etc.
Directions and Parking Instructions
Not everyone will be familiar with the location. If possible, include a map with parking instructions. It'll also be helpful if you can include a complimentary parking coupon with the invite.
Names of Speakers
If your event is a business event and you are able to confirm your speakers and preferably their speaking topics, include it in their invitation.
Statistics have shown that event invitations which includes speaking topics and especially the names of who's speaking typically get a higher response rate than those without.
VIP and Guest of Honor
Include the name of the VIP or Guest of Honor can be a great crowd puller and can be one of your major selling points.
Website Address
If you have a website address, don't forget to include that in your invite. And remember to keep it up to date on the latests updates.
