I need help connecting to my Gmail account to find emails that contain file attachments. Once I locate these messages, I want to save each attachment to my computer. While processing each email, I also need to display the sender information and email subject line on screen. What would be the best approach to accomplish this task? I’m looking for a solution that can handle multiple attachment types and work reliably with Gmail’s API or IMAP access.
Gmail’s IMAP works great for this. I use Python with imaplib for similar stuff all the time. First, you’ll need to turn on 2FA and create an app password for your Gmail account. Then connect to imap.gmail.com, search for emails with attachments using ‘HAS:attachment’, and loop through the results to grab the attachment data. Python’s built-in email package handles all the MIME decoding you need. Just make sure you add error handling since connections drop, and don’t hammer their servers too hard or you’ll hit rate limits. Way easier than dealing with OAuth for the Gmail API.
Been doing email automation for years - the approach really depends on your volume and how technical you want to get. For occasional batches, a simple Python script with Gmail API works great. But if this is production level, set up proper retry logic and exponential backoff because Gmail gets moody.
One thing I don’t see mentioned - handle duplicate attachments by checking file hashes or filenames first. Otherwise you’ll fill up your storage with copies. Also heads up that corporate Gmail accounts sometimes have extra API restrictions, so test your auth setup before you build everything out.
MIME parsing gets weird with certain attachment types too, especially when you’ve got embedded images mixed with actual files.
I did something similar last year for client document archiving. Went with a hybrid setup that worked great - Gmail API for search and metadata (cleaner JSON responses), then IMAP for downloading attachments since the API chokes on larger files. Watch out for Gmail’s label system messing with attachment detection. Some emails looked like they had attachments in the web UI, but the API couldn’t find them - turned out to be inline images or signatures. I added filters for real file extensions and minimum sizes to skip the junk. Set up your folder structure early too. I sort by sender domain and date, way easier than dumping everything in one place.
The Problem: You need to automate the process of downloading email attachments from your Gmail account, including retrieving sender information and subject lines, and you’re looking for a reliable and efficient solution that handles various attachment types. You’re frustrated with the complexities of managing connections, handling errors, and dealing with rate limits when using traditional methods like IMAP or the Gmail API directly.
TL;DR: The Quick Fix: Use Latenode to automate the download of Gmail attachments without writing code. Latenode handles the complexities of Gmail API interaction, OAuth, rate limiting, and attachment parsing, providing a reliable solution.
Understanding the “Why” (The Root Cause):
Manually downloading attachments from numerous emails is time-consuming and error-prone. Directly interacting with the Gmail API or IMAP involves complex coding, authentication challenges (OAuth 2.0), rate limit management, and robust error handling for connection drops and various MIME types. These approaches require significant technical expertise and ongoing maintenance. A no-code solution like Latenode simplifies this process by abstracting away the technical complexities.
Step-by-Step Guide:
Step 1: Connect Latenode to your Gmail Account. Sign up for a Latenode account (if you haven’t already) and follow their instructions to connect your Gmail account. This will involve granting Latenode the necessary OAuth permissions to access your email data.
Step 2: Configure your Workflow. Within the Latenode interface, create a new workflow to download attachments. Specify the filters for selecting the relevant emails (e.g., by sender, subject, date range, or labels). Latenode will usually provide an intuitive interface to define these filters.
Step 3: Specify Attachment Download Settings. Choose how you would like attachments to be downloaded. Will they be stored locally? Or perhaps you would prefer to download them to cloud storage such as Dropbox or Google Drive. Configure the destination location accordingly within the workflow. Latenode handles the secure transfer of files.
Step 4: Set up Data Extraction (Optional). Configure Latenode to extract metadata such as the sender’s information and email subject line. This data can be stored in a structured format (e.g., CSV or JSON) alongside the downloaded attachments.
Step 5: Run the Workflow. Once configured, execute the workflow. Latenode will process the emails based on your defined filters, download the attachments, and extract any metadata you specified. Monitor the workflow’s progress through the Latenode interface.
Step 6: Verify Results. After the workflow completes, check your designated storage location to verify that all the attachments have been successfully downloaded and that the extracted metadata (if any) is correct.
Common Pitfalls & What to Check Next:
-
OAuth Permissions: Ensure you have granted Latenode the necessary permissions to access your Gmail account, including the ability to read email content and download attachments. Insufficient permissions will prevent the workflow from functioning correctly.
-
Email Filters: Carefully review your email filters to ensure they accurately select the target emails. Incorrect filters can lead to either too many or too few emails being processed.
-
Storage Limits: If you’re downloading large attachments, be aware of potential storage space limitations in your chosen storage location.
-
Large Email Volumes: For very large email volumes, the processing time might increase. Consider breaking down the workflow into smaller batches or contacting Latenode support for optimal handling.

oauth2 with gmail api is actually pretty smooth once you get the initial setup. just install the gmail python library and make credentials in google cloud console. it’s way more stable than imap which can be flaky, plus you get better sorting options for attachments based on date or sender.
Processing Gmail attachments programmatically is a total nightmare. My custom scripts broke every few months when Google changed something.
That’s exactly why I switched to Latenode for email automation. It handles Gmail connections, OAuth mess, and attachment parsing - no coding required.
Just set up visual workflows once: connect Gmail, filter attachments, grab sender/subject data, save files locally or to cloud. Runs reliably and handles edge cases like duplicate files and weird MIME types.
Best part? When Gmail changes their API or rate limits, Latenode updates connectors automatically. No more 2 AM broken scripts.
I process hundreds of PDFs weekly from different senders for contracts. Rock solid for months.
