If people are not receiving emails sent through Planning Center, your Organization Administrator can unblock those email addresses.
First, ask the person not receiving emails to check their Spam folder to ensure the emails aren't going there. If they're not going to Spam, follow the steps below to unblock the person's email address.
From the person's profile, select the error icon next to the email address.
If you know the email address should work, click Unblock to unblock the email.
If the email address is actually incorrect, you can edit or delete it by clicking the pencil on the profile page.
