FAQs

Can I track if my recipient opened the attached file?

No, the tracking will only be with respect to the campaign. We will not be able to track whether the attachment file got downloaded/opened.

What happens if my attachments exceed the maximum file size limit specified by my email delivery provider?

This will lead to a hard bounce and the email will not be delivered.

What happens if the URL for the file attachment was faulty or incorrect?

The email campaign will not be delivered and this will be reported as 'Attachment failures' on the campaign analytics page.

What happens if the attachment files are missing in the URL I provided?
