To ensure reliable email delivery and consistent performance across all workspaces, SmartSuite enforces daily email sending limits on certain plans.
My email did not send: check these five things, in order
Administrators and Solution Managers can open the automation's run history to see the failed step. If you have neither role, send this page and the record name to the person who manages the solution.
The daily limit. Trial, Team and Professional workspaces have a workspace-level limit on emails sent in a 24-hour period. When it is reached, any automation or action that sends an email fails with a message that the workspace has reached its email sending limit; sending resumes when the window resets. See How Email Limits Work.
The recipient count. Send an Email allows up to 50 addresses combined across Send To, CC and BCC; more than that may produce delivery errors. See Recipient Limits.
Your own mail account. The limit counts emails sent from SmartSuite's own address: the Send an Email action, which sends from a generic SmartSuite address, and system notifications. The Google Gmail and Outlook Email actions send from the connected account and are outside the limit, so switching to one of them is the fix for the Email Sending Limit Reached error. See Common Automation Error Troubleshooting.
The automation did not run at all. The automation did not run, or the run failed before the email step. The checks are in Fix an automation that did not run.
A higher limit. A workspace that regularly sends a high volume of email can contact SmartSuite Support to discuss the options. See What You Can Do If You Reach the Limit.
Still stuck: select the chat button in the lower-right corner of SmartSuite. The panel shows the current service status under Search for help; to reach support, select Ask a question. Include the automation link (the three-dot menu, then Copy Link), the time of the send and the link to the record. To copy it, select the link icon next to the record number, or choose Copy Link in the record's three-dot menu. The full fix guide is Fix an automation that did not run.
Which Plans Are Affected
Trial, Team and Professional workspaces have a daily email sending limit.
Enterprise and Signature plans are not subject to email sending limits.
How Email Limits Work
The limit applies at the workspace level, covering all emails sent from the workspace within a 24-hour period.
This includes emails sent by automations, system notifications, and other email-based actions.
Once the daily limit is reached, any automation or action that attempts to send an email will fail and display a clear message indicating that the workspace has reached its email sending limit.
Email sending automatically resumes when the 24-hour window resets.
Recipient Limits
The Send an Email automation allows up to 50 total email addresses combined across Send To, CC, and BCC. Exceeding 50 recipients in total may result in delivery errors.
What You Can Do If You Reach the Limit
If your workspace regularly sends a high volume of emails and needs a higher limit, you can contact SmartSuite Support to discuss available options.
These limits help maintain dependable email delivery for all customers while ensuring SmartSuite continues to perform reliably at scale.
