  • Goal: Trying to use Workflow for sales, spend fluctuations alerts via E-mail -->

  • Steps:

  • Details:

  1. Email sent to multiple recipients is considered one email, or multiple.
  2. If there is a way to increase email/hour limit
  3. Invalid login: 451 Internal server error - is this recipient side issue or sender side.

Hi @Chetan_Modi,

Our rate limit is based off of the number of recipients (not the number of Retool email queries)

Paying users can send up to 120 Retool Emails per hour while free users can send up to 50 Retool Emails per day. That error indicates you're hitting the limit. How often is that happening? What would you need for your use case? Retool email resource running into error: Invalid login: 451 Internal server error - #2 by Alice

I wanted to let you know that there might be a discrepancy in the error message for the email feature. It currently says, "You cannot send more than 50 per hour," while the limit appears to actually be 50 emails per day

Hi @Arthur_moiret_bisiaux,

Thanks for flagging! I'll make sure our team is aware.

Free user here. Can't send more than 8 or 9 emails from a loop block as part of a Workflow, before it shows the 50 email-an-hour error. Tried setting the execution to Sequential to no avail.
