Hi, @RyanFromWhidbey. First, to be clear, Netlify provides DNS hosting services but we do not provide any emails hosting at all.
You can configure the DNS records for your email service at Netlify. However, the emails services themselves are always hosted outside of Netlify. This might be Gmail, Zoho, email provided by the domain registrar, or any other third-party email service.
If you are getting “email limit reached” errors they can only come from your third-party email service and only their support team can assist with resolving that.
When moving to Netlify DNS, one common issue is not transferring “all required records” to Netlify. I put “all required records” in quotes to highlight that we don’t know what “all required records” are for your (or any other domain). That is something you must determine on your own as it is specific to whatever email hosting you are using and Netlify isn’t privy to that information.
Once you do have a list of all required records, it is important to copy them to Netlify DNS before making the name server record changes to finalize the switch to Netlify DNS.
There is more about this in detail here:
There is a section in the documentation above titled:
I did not copy my records before switching name servers and my email (or other service) stopped working. How do I fix this?
The answers in that section may be helpful in resolving this issue. If there are other questions about this, please let us know.
