Troubleshooting email delivery issues for customer contacts
Description

If an email fails to send due to an error. Here's why it happens and how to resolve it.

Invalid Email

Reason The email address doesn’t look right. The email mistyped (‘gmail’ instead of ‘gmail’) or mixed up the address format (‘[email protected]’ instead of ‘[email protected]’).
Resolution Check the email format in Contacts. Verify the address before contacting the customer. If delivery issues arise, use another contact method. Contact support to resolve this issue.

Mailbox Error

Reason It looks like there’s a problem with your customer’s mailbox right now. It could be full or offline.
Resolution This problem is often temporary. Try sending it again in a few days or getting in touch with your customer another way. Once resolved, you’ll be able to resend any emails that didn’t get through.

Autoresponder

Reason While sending your email, we received an automatic response from your customer’s mail server. This could be an out-of-office message or an address not found error.
Resolution If your customer hasn't responded promptly, email them using your regular email program. This way, you can see if there's an automatic response. Inform your customer about the issue you're encountering.

Blocked

Reason The mail server or internet service provider (ISP) used by your customer blocked the email delivery.
Resolution Servers or ISPs could block the emails. Ask your customer to check for any blocks. We send from [email protected]. Retry sending after removing blocks. 

Spam

Reason Your customer has reported your email as spam. This means their mail service won’t let our mail service send them any more emails.
Resolution

To unblock spam, get customer consent for your emails. Verify the correct email address and permission to email. Emails come from [email protected]. Contact support to resolve this issue.

Not Delivered

Reason Mail delivery can fail for various reasons. Here are a few things to check or ask your customer to verify to ensure the email gets delivered.
Resolution

Check the email address is correct and free of typos. If the email fails to send because of a full inbox or a deleted address, send a test message and check for error responses. Ask your customer if their spam filter is blocking your email.
