Hi @Zam 

Help articles for using Email by Zapier: https://zapier.com/apps/email/help

Symptoms

When using the Send Email action, Zapier might display an error message: “Email by Zapier: Sorry! That is too many emails sent. Please try Mandrill, Mailgun, Gmail, or others for bulk email”. This usually occurs when the Zap is turned on.  

Causes

This happens when the Email by Zapier app limits the number of emails you can send within a specific timeframe to prevent spam.  The allowed email limit per hour depends on your Zapier plan:

• Trial or Free plan: 5 emails per account per day.
• Any paid plan: 10 emails per account per hour.

When the error message says “Held” like that, is it held until after the hour is up and then released? Can I stack emails in the queue and then they will be sent out as the rate limit allows, or if I go over the rate limit in any given period is it stuck in limbo forever?

Hi @IgoleHadod 

You would likely need to go to the Zap Runs and manually replay.

You can add a Delay (After Queue) step to space out the processing of the Email step.

NOTE: Adding a Delay step will create a multi-step Zap that requires a Zapier paid plan.

Held

A held status indicates that the Zap run is being held for one of a few reasons.

Held statuses can be caused by:

• Too much data: too many steps (100+) would have been triggered when Zapier checked for new data. This "flood protection" prevents you from accidentally using a large number of tasks. 
• Disconnected app: one of the app accounts used in the Zap is disconnected.
  • Reconnect the app account, then replay the held Zap run.
• Task limit reached: the account reached the task limit for its plan or uses a premium app that is not supported by the plan.
  • To replay the held Zap run, upgrade your Zapier plan.
• Payment issue: the payment information on the account has expired.
  • To replay the held Zap run, update your payment method.
• Restricted app: in Team or Company accounts, your Zapier account owner or admin has limited the use of the app and you do not have permission to use it.
