When you try to send an email through LeadSimple, you may sometimes encounter an error that says "Access Denied: You need to reconnect your email account".
This means that your email account has become disconnected from LeadSimple so the software can't send emails from that email address until you reconnect it.
To connect your email account, click your name in the side bar,
click the "Email Accounts" link,
and click the red "Reconnect" button on the right-hand side of your previously connected email account. You may be prompted to provide additional information so simply follow them when they appear.
