A few things can cause broken code or attachments in a delivered campaign.
Below, you'll find information on the most common causes and how to troubleshoot them.
- The spam filter or email server scanning your incoming message may have seen something it doesn't like in your content and has "quarantined" the message, which creates the format changes you're seeing.
The IT group that manages your subscriber's incoming email servers will be the best source to determine why the spam filter has flagged your email as spam.
- Anti-virus programs will sometimes "break" multipart email templates and display them as raw HTML code.
To fix this, your recipient will need to change their anti-virus settings to accept or trust multipart email messages. For additional guidance, contact the software company that produces the anti-virus program.
- Some email programs will display multipart messages as garbled code or an attachment if an email message doesn't contain both HTML and plain-text content.
If you see this issue when sending a test email, send your test from the Confirm step of the campaign builder instead of the Design step.
- If you send to Outlook accounts, remove the "To:" field personalization on the Setup step of the Campaign Builder.
