Following up with the meeting planner is crucial to your success as a Speaker.  I have listed a few ideas below to add to your arsenal and keep being pleasantly persistent with meeting planners!

1. Send the latest media interview (TV, Radio, Podcast, etc) that you were a guest on to help showcase your expertise.
2. Find out when their birthday is and send them a card in the mail.
3. Send a copy of your latest blog post, white paper or if you host your own show, ask if they would like to be on your mailing list.
4. Send them article of interest for their industry.
5. If you are speaking near their area, invite them to be a guest to hear you first hand.
6. Introduce them to industry contacts that would benefit them or their business.
7. Send a followup email or conduct a call just to check in.
8. Send a thank you note. 
9. Connect with them on social media outlets.
10. Send a promotional item, or copy of your book as a gift.
