- Complete email tests
Next, perform the following email tests to ensure your email service is working properly:
- Test sending and receiving emails between two email addresses with the same domain. For example, using the domain example.com, conduct a test where the email addresses thomas@example.com and angela@example.com send and receive emails to and from each other.
- Test sending emails from a Lark business email address to an external email address.
- Test sending emails from an external email address to a Lark business email address.
- If you have an email address that uses a different domain provided by the original business email provider, test sending and receiving emails between that address and a Lark business email address. If you don't have an email address with a different domain, you can skip this test.
