If you're looking to send a one-time email to all of your customers, your options within your instance may be limited to either using triggers or creating an announcement that everyone will see upon logging in. However, we recommend utilizing a third-party campaign manager like Mailchimp to send out mass emails to your entire customer base. With Mailchimp, you can easily export your contacts and import them into the platform. Not only is the importing process simple, but Mailchimp can also alert you if any of your contacts have bad email addresses. So, if you're looking for a reliable solution to send mass emails to your customers, Mailchimp is a great choice to consider.
