Using Attachments in Automations

Automation emails can include file attachments — PDFs, images, and other documents — so contacts receive the resources they need right alongside your message. This article covers what you can attach, how to add attachments to a step, and best practices for deliverability.

What you can attach

PDF documents (guides, brochures, reports)
Image files (JPG, PNG)
Other documents (limited by file size)
Resources and educational materials

File Size Limits

Maximum file size per attachment: 3 MB
Recommended: Keep attachments under 5 MB for optimal deliverability
Each email provider has different limits, so deliverability may fluctuate based on the recipient's provider.

Adding attachment to automation steps

Navigate to Automations and create a new automation or edit an existing one.
Add an Email step where you want to include attachments.
Compose your email content.
Look for the Attachments or Add Files option.
Select your PDF or other file from your computer.
Wait for the upload to complete.
Verify the file appears in the template.
Save the automation step.

Best Practices for Automation Attachments

File Preparation

Name files clearly and professionally (for example: 2025_Financial_Planning_Guide.pdf).
Compress large files to reduce size — free file compressors can be found online.
Run a test with the file to ensure accuracy when received and opened.
Include a quick file description in the body of the email.

Deliverability Considerations

Smaller attachments have historically better deliverability.
Some email providers flag large attachments as spam.
Consider linking to documents instead of attaching, especially for larger files.

Linking vs. Attaching

When to Attach Files

Small files under 2 MB
Documents contacts need to save or print
Personal or confidential information
One-time resources

When to Link Instead

Large files over 5 MB
Frequently updated content
Resources that may change
Content you want to track opens on

Setting Up Linked Resources

Upload the document to your website or cloud storage.
Generate a shareable link.
In the automation email, add a link with descriptive text.
Example: "Download our complete guide here."

Troubleshooting & Attachment Issues

"My attachment won't upload."

Check that file size is within limits.
Ensure the file format is supported (PDF, JPG, PNG).
Try compressing the file.
Check your internet connection.
Try a different browser.

"Contacts say they didn't receive the attachment."

Check spam folders — attachments can trigger spam filters.
Verify the file uploaded successfully in automation settings.
Send a test email to yourself to confirm the attachment arrives.
Consider file size — very large files may be blocked.

"The attachment looks wrong or won't open."

Test the file on multiple devices before adding it to an automation.
Ensure the PDF is not password protected or corrupted.
Try re-exporting or re-saving the PDF.
Check that the file wasn't saved in an unusual or proprietary format.

"Can I change an attachment after an automation is running?"

Changing the attachment in automation settings affects future sends only.
Contacts who already received emails keep the original attachment.
To update, edit the automation step and replace the file.
Consider creating a new automation version for major changes.

FAQs on Automation Attachments

Q: How many attachments can I include in one automation email?

A: Typically, 1–3 attachments are recommended for deliverability. Too many attachments can trigger spam filters.

Q: Can I use different attachments for different contacts in the same automation?

A: No — all contacts going through a specific automation step receive the same attachment. For personalized documents, you'd need to set up different automation branches or steps.

Q: Will attachments work in text-only emails?

A: Attachments are sent with both HTML and plain text emails. Recipients can download them regardless of email format preference.

Q: Can I attach compliance PDFs that are automatically generated?

A: If you have compliance PDFs generated through Levitate's compliance flow, those are handled separately. For automation attachments, you'll need to manually upload the PDF file.

Q: Do attachments count against my sending limits?

A: Attachments don't directly count against sending limits, but large attachments may slow sending. File size affects deliverability more than count limits.

Q: Can I attach files from Google Drive or Dropbox directly?

A: Currently, you'll need to download the file from cloud storage and upload it to Levitate. Direct cloud integration for attachments may not be available.

Q: Will mobile users be able to view PDF attachments?

A: Yes. Most mobile devices can open and view PDF attachments. Recipients may need a PDF viewer app depending on their device.

Q: Can I see who downloaded or opened my attachment?

A: Attachment-specific download tracking may not be available. You can see email opens, but not separate attachment analytics.
