About email attachments about-email-attachments
You can attach one or more files to an email delivery.
There are two possible cases:
- Select a file and attach it to the delivery as it is.
- Personalize the content of the attachment for each recipient. In this case, you need to create a calculated attachment: the name of the attachment is computed at the time of delivery for each message depending on the recipient. The content can also be personalized and converted into PDF format at the time of delivery, if you have the Variable Digital Printing option.

To avoid performance issues, images included in emails cannot exceed 100 KB. This limit, set by default, can be changed from the NmsDelivery_MaxDownloadedImageSize option. However, Adobe strongly recommends to avoid large images in your email deliveries.
Adobe also recommends to limit the size and number of attached files. By default, you can only add one file as an attachment to an email. This threshold can be configured from the NmsDelivery_MaxRecommendedAttachments option.
