4aGoodCause uses a transactional email service, SendGrid, to send donation receipts, alerts, and other emails on your behalf. 

To improve your deliverability, SendGrid automatically adds sender identification (authentication) to the emails. This identifies who is sending the email and helps protect email senders and their recipients from spam, forgery, and phishing. Authentication helps email providers like Gmail, Yahoo or Hotmail understand where the email is originating from.  

By default, when a donor receives a donation receipt, they will see the From Email Address you enter into your campaign combined with a "via 4agoodcause.com" tag. An example of sender identification might be "donations@yourdomain.org via 4agoodcause.com".

Many email providers such as Gmail and Yahoo have specific rules to block email that comes "via" third-party services like 4aGoodCause. In addition, some nonprofit organizations have specific settings on their email domain to not allow emails to be sent on your behalf by a third party (DMARC policy).

For these reasons, we strongly recommend you authenticate your domain with our email provider. Without authentication, you risk some of your donation receipts being blocked or getting caught in spam filters. 

Authentication will give our email provider permission to identify your receipts as coming directly from you and the "via 4agoodcause.com" tag will be removed for all receipts coming from your domain. 

To authenticate your domain, you'll need to make a few changes in your domain's DNS records, so you will probably want to ask your website manager or domain registrar for help. To have your email domain authenticated with our email provider please contact us at support@4agoodcause.com to receive instructions to give to your website manager or domain registrar.
