Guest Speaker Invitation Letter

Formal Invitation Letters for Guest Speakers, Keynote Speaker, Workshop speakers/facilitators can be quite a challenge to write if you have never written one.  Like every letter, an invitation letter usually reflects the personality and the values of the person or organization writing it.  A good guest speaker invitation letter should be easy to read, respectful and clear, with all the information your guest speaker needs to make a decision.

Please use this sample guest invitation letter as a source of inspiration for you own letter. You can make your letter less formal or even more formal, as long as you keep all the information necessary for your invited speaker to decide whether to accept your invitation or not.

When and How to deliver a guest speaker invitation letter

Guest speakers play a major role in any event. As a result, it is important that the organizers of the event send out the guest invitation letter as early as possible. For popular speakers and celebrities you may need  up to 6months to two years.

Many speakers today will be happy to receive an email invitation. However it is advisable to send a hard copy of the invitation letter to the guest speaker. You may then choose to send a scanned or PDF copy of the letter to the speaker via email.
