cOASIS uses Amazon Web Services (AWS) to send emails from cOASIS. AWS requires the registration of the domain or domain email address to verify your ownership of the domain. Major email providers (e.g., Gmail.com1 and Yahoo.com2) have recently updated their guidelines to require new DNS entries to authenticate the sender email, reduce spam, and to increase email deliverability.
Best practice
The current best practice is to register the domain you will use for sending emails from cOASIS (e.g., myassociationdomain.com). This domain will be registered with AWS. Registering the domain will have the following outcomes:
1. Allows sending emails from your domain through cOASIS
2. Does not require the registration of specific email addresses
3. Allows sending email with any domain-based email address as the MAIL FROM or REPLY-TO address
4. Maximizes deliverability based on current security and spam guidelines
5. Requires creating multiple new DNS entries for your domain with your domain registrar or DNS provider
6. The registration process can take several days to complete
