n8n Review (2026): Our Hands-On Gmail Automation Test
We did not review n8n from a feature checklist alone. We created an n8n Cloud account, connected Gmail and Google Drive, built a live workflow, published it, sent a real PDF email, and confirmed that the attachment was automatically renamed and uploaded to Drive.

What we built
- Gmail Trigger
- Gmail search filter:
has:attachment filename:pdf - Download Attachments enabled
- Binary file received as
attachment_0 - Google Drive → Upload File
- Filename expression:
{{ $now.toFormat('yyyy-MM-dd') + '_' + $binary.attachment_0.fileName }} - Publish workflow
- Send a fresh PDF email
- Verify the renamed file in Google Drive
What we liked
1. Strong data visibility
n8n exposes incoming JSON and binary data clearly. During testing we could inspect the sender, subject, message ID, attachment binary, MIME type, and original filename.
2. Powerful expressions
The date-based filename was created directly with an expression. This feels closer to programming than a strictly no-code tool, while remaining approachable.
3. Execution-based pricing
n8n Cloud bills around complete workflow executions rather than charging separately for every node in the workflow. That can be attractive when workflows become step-heavy.
4. Self-hosting option
n8n gives technical users an infrastructure option that many cloud-only automation platforms do not.
What we disliked
1. Gmail permissions are broad
Google OAuth permissions can look intimidating. A dedicated test account is a sensible choice when evaluating the integration.
2. More technical than Zapier
n8n is not the easiest tool for someone who has never worked with JSON, binary fields, or expressions.
3. More setup detail than Make for some basic flows
Make's visual module mapping can feel simpler for straightforward filters and routers. n8n becomes more compelling as the workflow logic gets more technical.
4. Cloud is not free forever
The hosted Cloud product has a trial and then paid plans. The no-license-cost core option is self-hosted Community Edition, which requires infrastructure management.
n8n vs Make vs Zapier — our current view
| Tool | Best fit |
|---|---|
| Zapier | Fastest beginner setup |
| Make | Visual multi-step business automation |
| n8n | Technical flexibility, code-friendly logic, self-hosting |
Who should use n8n?
- Users comfortable with technical concepts
- Teams building complex workflows
- Users who want API/code flexibility
- Teams that may want self-hosting
- Users who prefer execution-based pricing for multi-step workflows
Verdict
n8n is worth testing if your automations are becoming too complex for purely no-code tools. For our Gmail PDF workflow, it worked reliably after configuration and gave excellent visibility into the underlying data.
