How to bypass Salesforce's mass email limit?
On the Salesforce platform, you can send mass email (using the API or Apex) to a maximum of 5000 external email addresses per day per org. Under certain conditions, Salesforce Support may temporarily raise your org's mass email limit. For details, see Mass Email Limitations in the Salesforce Help.
Depending on your business, your org may permanently need to send more emails per day. To support this, JustOn can integrate with the Amazon Simple Email Service (SES) to send out invoices, dunning reminders and account statements.
The Amazon SES integration is an enterprise extension feature and subject to additional charges. For details, contact our service team.
For details about enabling the Amazon SES integration, see Enabling Amazon Simple Email Service.
