Digital Onboarding can send emails using your existing SMTP service by filling in the same fields you would to configure an email client. There are two caveats to this approach.
- We can't gather stats on bounced emails because we won't receive notifications about bounces.
- You will have to scale the service appropriately as load increases.
If these caveats are acceptable this is a suitable option. If they are not acceptable it is recommend you use a dns approach so that we can gather stats on bounced emails and scale the service automatically as load increases.
