Bounces & Undelivered Emails

Sometimes, you will receive a note within your Opportunity Details page that alerts you about an undelivered email. There are various reasons why your email may not have delivered.

Bounce Flags on Contacts

Pitchbox shows a red triangle bounce flag next to a contact to show that an email has previously bounced to this recipient.

Bounce warnings (red triangle)

When an email to a contact bounces, Pitchbox adds a note on the Opportunity Details page and marks the contact with a red bounce triangle. Pitchbox then stops sending further emails to that contact. This protects your email account's reputation.

Why an email might not be delivered

Incorrect email address. This is the most common cause. One wrong character, such as a missing letter or an extra space, is enough to make an email bounce.

Spam filters and blacklists. Email providers filter out messages that look like spam. Suspicious wording, too many links, or large attachments can cause an email to be flagged and never reach the inbox. Recipient servers may also block your emails if your sending IP address or domain is on a blacklist, often because of earlier spam complaints. You can check the health and deliverability of your email address on the Email Accounts page using MXRight.

Full mailbox. If the recipient's inbox is full, their server may reject new messages until space is cleared.

Temporary server issue. Server outages or configuration errors can stop delivery even when everything is set up correctly on your end.

Blocked sender. The recipient may have blocked your email address or domain, either deliberately or by mistake.

Removing a bounce flag

If you've fixed the problem, or want to keep emailing the contact anyway, click the red bounce triangle and select "Click to Remove Bounce Flag".
