Just to let you know:
Sometimes, things happen and we may not be able to deliver a webinar you've booked to attend. If that's the case, we'll let you know as soon as possible and we'll reschedule it.
If you can't make the webinar you've booked to attend then that's OK. If you could let us know you won't be joining us that would be great. We hope to be running these regularly so if you'd like us to let you know when it is taking place again, let us know.
If you have any questions, then please send an email to firstname.lastname@example.org.
