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.
Reconnecting Your Email
First, go to your profile page by clicking your name in the top left.
Scroll down to Email Accounts and find your disconnected email account.
Next, click "Connect" next to the email account. It may be a red "Reconnect" button. You may be prompted to provide additional information so simply follow them when they appear.
