You may have noticed that when an automatic receipt goes to your donors in response to an online gift, it is sending from email@example.com
This will not impact any deliverability of your receipts (we have a phenomenal deliverability rating), but, you may want the additional customization so your donors feel like they know who is messaging them.
To allow for this to work, you will need to add two text records to your DNS settings.
Follow the instructions here, and add these two records (SPF and DKIM) on your domain.
Once you are done, let us know at firstname.lastname@example.org and we can monitor the status!
