How Squarespace Domains writes each name
The same record is written differently depending on the panel. At Squarespace Domains:
Domain root (SPF)
- Type
- TXT
- Name
@- Value
v=spf1 include:_spf.google.com ~all
DMARC
- Type
- TXT
- Name
_dmarc- Value
v=DMARC1; p=none; rua=mailto:informes@empresa.example
DKIM (example)
- Type
- CNAME
- Name
selector1._domainkey- Value
selector1-empresa-example._domainkey.empresa.example
Example values: yours depend on which services send with your domain. An SPF copied from somewhere else may leave out your invoicing program.
Check that it has gone in properly
DNS changes take anything from a few minutes to a few hours to show. Once you have pasted the records, run your domain through the X-ray.
