For now we are able to provide default integration using the following known email providers:
Steps to send through those providers:
- add provider credentials under Setup->Email config
- authenticate sending domain within your provider account
- if sending domain is different than your main account domain, contact us to add the new domain under your account
- for example sending from email.example.com and your account is registered with example.com we will need to add sending domain under your account
Test each email provider after adding its credentials. Sending email address is important to match the authenticated domain.
Make sure your other email provider is able to cope with our email sending volume. Read more here.
