What are the salesforce email limits?
I use Apex and Flow to send acknowledgment emails to customers in different scenarios. From Apex, I use Messaging.Single email. I want to know if the email sent from Apex and flow will be counted against the limit of 5000 because, as per doc, SingleEmailMessage itself has a 5000 limit.
I have come across an article that says the salesforce email limits up to 5,000 external email addresses per day for each licensed organization. If the orgs are created before Spring '19, then the daily limit is only for emails sent via Apex and Salesforce APIs (excluding REST APIs). If orgs are created after Spring '19, it applies to email alerts, simple email actions, Send Email actions in flows and REST APIs.
