Below is some suggested wording for your use in an email to invite volunteers to your VolunteerHub site. Please fill in the underlined sections with wording appropriate to your organization.
Dear Name of Volunteer,
Name of Your Organization is excited to introduce our new and easy way to sign up for volunteer opportunities! Please visit our new site for volunteer opportunities at https://nameoforganization.volunteerhub.com and click the "Create Account" link in the top-right corner to create your volunteer account. Once you create your account, you will be directed to a list of volunteer opportunities. Just click on the "Sign Up" button next to an opportunity - that's it!
Thanks to our collaboration with VolunteerHub, it is now easy and convenient for you to sign up for opportunities that fit your schedule or cancel shifts you can no longer attend.
Thank you for your support!
Best regards,
Name of Volunteer Coordinator
