Can I Send Attachments in a Campaign Sequence?
No, attachments are not supported in campaign sequences.
This is a deliberate choice, as attachments can significantly hurt your email deliverability. To help protect your sender reputation and inbox placement, attachments are disabled for automated sequences.
When Can I Use Attachments?
You can still send attachments in the following cases:
Manual replies sent from the master inbox
Programmatic replies sent via the API
If you need to share files as part of a sequence, we recommend using a link to a hosted file (such as a Google Drive or Dropbox link) instead.
