"You have exceeded your quota for Email Delivery Service"

We send invoices out to clients through ERPNext. It’s been working fine for the past month but today we got an error saying that we’ve exceeded the quota for email delivery service. The error message was this:

press.api.email.EmailLimitExceeded: You have exceeded your quota for Email Delivery Service. Try upgrading it from, Frappe Cloud

Is this an issue with Gmail? (our email provider) or with ERPNext? I read in some other forums that there is a limit to the number of emails sent out in a day but we shouldn’t be close to those numbers. At most, we send out maybe 100 emails a day. What could be the issue here? Do we need to upgrade the Frappe Hosting plan?

@wenybai There is no email limitation from frappe/erpnext side you have to increase email limit from email provider side.

@wenybai Seems like you are using Frappe Cloud - Email Delivery Service to send emails from your site whose quota limit is exceeded. In case you have a default Email Account setup you need to uninstall the Email Delivery Service app from your site or raise a support ticket for the same at support.frappe.io.

Yes thank you, I didn’t realize Email Delivery Service was a separate app from ERPNext. I was able to upgrade my plan to increase the quota from Frappe Cloud and everything is working now!
