Question

Gmail search throttling issues with Zapier automation

I created a Zap to search my Gmail account for emails with a specific subject line and then count the number of emails that match that specific subject line. This search repeats 5 times for 5 different specific subject lines.

The Zap worked great for a few days but now every time the Zap runs it is put on hold because the Gmail search is being throttled.

I read that this can be due to the number of API requests per hour so I added a 1 hour delay between each Gmail search within the Zap however the issue is still occurring.

Also I do have a paid professional Zapier plan.

Is there a potential fix for this?

Hy ​@GenerousZaps 

You can try:

Combine 5 searches into 1 using Gmail's OR operator:

subject:("Subject A" OR "Subject B" OR "Subject C" OR "Subject D" OR "Subject E")

Or use curly brace syntax:

subject:{SubjectA SubjectB SubjectC SubjectD SubjectE}

This reduces 5 API calls → 1 API call (25 units → 5 units per Zap run).

Why This Works

  • Cuts API usage by 80% immediately

  • Keeps you safely under the 250 units/second burst limit 

  • Removes need for 1-hour delays entirely

If Throttling Persists

Add a "Delay After Queue" step (not internal delay) to space out entire Zap runs, or check if other Zaps access the same Gmail account—all share the same per-user quota.

Hope this helps you get it sorted!
